Gridview Button For Calling Sqldatasource.update Fails
Aug 1, 2007
<!-- Trying
to create a GridView Survey form:
Hi [User]
Do you have these assets?
[Gridview]
Tag Number Response
123
[Yes ] [No] [Comments textbox]
234
[Yes ] [No] [Comments textbox]
Goal: The desire
is for the user to click Yes or No and have the database updated with the
user's name, date, response and any comments.
So far, I have
created SqlDataSource with Select and Update commands, created the gridview and
response buttons, setup the RowCommand and On_Updating Functions.
Problems:
1) If I call the update() function for SqlDataSource1 and misuse the Defaultvalue parameters to run the sql, no update is posted to the database.
2) If I use the On_Update function to set the parameter values, I get "Data type mismatch in criteria expression." (Additionally, the On_Update function runs twice which I don't understand)
Can anyone tell
me what/why? (and how to fix it?)Sorry for the deluge, but here is the code:
-->

I want to update two tables in one page. So I created two FormView bound on two SqlDataSource controls, and I create a Update button on the bottom of page. And I writen some codes as below:
btnUpate_Click(object sender, EventArgs e){
sqlDataSource1.Update();
sqlDateSource2.Update();}
But, the records haven't updated.
In SqlDataSource2_Updating() function, I found all the parameters is null.
So, how to modify my code to do it.

I have a gridview that is tied to a SQLDataSource control which is inside an update panel.
What I'm trying to accomplish is when the page is loaded the gridview is filled from the SQLDataSource. I have some textboxes also on the page so that the user can add new items to the gridview. The update panel trigger is tied to my code behind page through a button click which added the new data to the DB with an INSERT statement. Since the gridview was inside the update panel I thought when I placed the new data into the DB and the update panel caused the portion of the page that holds the gridview to refresh that the gridview would show the newly added data but it is not.
I am missing something but I do not know what. I tried adding a gridview1.databind() and SQLDataSource1.DataBind() but niether caused the update of the gridview as I had hoped.
Thanks for any of your help.

Hi all
I have a GridView on an aspx page, that is enabled for editing, deletion and sorting.
In the Page_Load event of the aspx page, i add a SqlDataSource to the page, and bind the source to the GridView.
When i click the update, or delete button, it makes a PostBack, but nothing is affected. I'm sure this has got something to do with the parameters.
First, i tried having the GridView.AutoGenerateColumns set to True. I have also tried adding the columns manually, but no affect here either.
The code for setting the commands, and adding the SqlDataSource to the page are as follows:
string strConn = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString; string strProvider = ConfigurationManager.ConnectionStrings["ConnectionString"].ProviderName; string selectCommand = "SELECT * FROM rammekategori"; SqlDataSource ds = new SqlDataSource(strProvider, strConn, selectCommand); ds.ID = "RammeKategoriDS"; ds.UpdateCommand = "UPDATE rammekategori SET Kategoribeskrivelse = @Kategoribeskrivelse WHERE (Kategorinavn = @Kategorinavn)"; ds.DeleteCommand = "DELETE FROM rammekategori WHERE (Kategorinavn = @Kategorinavn)"; Parameter Kategorinavn = new Parameter("Kategorinavn", TypeCode.String); Parameter Kategoribeskrivelse = new Parameter("Kategoribeskrivelse", TypeCode.String); ds.UpdateParameters.Add(Kategorinavn); ds.UpdateParameters.Add(Kategoribeskrivelse); ds.DeleteParameters.Add(Kategorinavn);
Page.Controls.Add(ds);
SqlDataSource m_SqlDataSource = Page.FindControl("RammeKategoriDS") as SqlDataSource;
if (m_SqlDataSource != null) { this.gvRammeKategorier.DataSourceID = m_SqlDataSource.ID; }
As mentioned - no affect at all!
Thanks in advance - MartinHN

Hi,
Using VS.NET 2008 Beta2, and SQL Server 2005.
I have a gridview bound to a linq data source, and when trying to update a row, I get an exception that no rows were modified.
The query generated is:
UPDATE [dbo].[package]
SET [owner_id] = @p5
WHERE ([package_id] = @p0) AND ([title] = @p1) AND ([directory] = @p2) AND ([owner_id] = @p3) AND ([creation_date] = @p4)
-- @p0: Input Int32 (Size = 0; Prec = 0; Scale = 0) [20006]
-- @p1: Input String (Size = 22; Prec = 0; Scale = 0) [Visual Studio.NET 2005]
-- @p2: Input String (Size = 26; Prec = 0; Scale = 0) [MSI_Visual_Studio.NET_2005]
-- @p3: Input Int32 (Size = 0; Prec = 0; Scale = 0) [10000]
-- @p4: Input DateTime (Size = 0; Prec = 0; Scale = 0) [11/07/2007 12:00:00 a.m.]
-- @p5: Input Int32 (Size = 0; Prec = 0; Scale = 0) [10001]
-- Context: SqlProvider(Sql2005) Model: AttributedMetaModel Build: 3.5.20706.1
If I run it manually on sql server, it fails until the directory column is removed. The type is varchar(50), with a uniqueness constraint. However, this is same type as the title column, which doesn't have this problem.
Thanks,
Jessica

Hi all,
I have a gridview bound with a SQLDataSource. I am using the Update feature of the SQLDataSource to update a SQL Server database with values entered into the gridview. However I am not getting it to work. I believe this is due to the controls that contain the user entries are not the gridview itself, but rather child controls within the gridview. I have been using the names of the actual controls but nothing happens. Upon submit, the screen returns blank, and the database is not updated. Here is some code:
<asp:GridView ID="GridEditSettlement" runat="server" AutoGenerateColumns="False" BackColor="Navy"
BorderColor="IndianRed" BorderStyle="Solid" Font-Names="Verdana" Font-Size="X-Small" DataSourceID="SqlDataSource_grid" AllowPaging="True" AllowSorting="True" ForeColor="White" DataKeyNames="legid">

<asp:BoundField DataField="StartDate" HeaderText="Start Date" ReadOnly="True" />
<asp:BoundField DataField="EndDate" HeaderText="End Date" ReadOnly="True" />
<asp:BoundField DataField="CounterpartDealRef" HeaderText="CP Deal Ref" ReadOnly="True" />
<asp:TemplateField HeaderText="Preliminary Settlement Price" ><ItemTemplate>

<AlternatingRowStyle BackColor="White" ForeColor="#333333" />
</asp:GridView>
<br />
<asp:SqlDataSource ID="SqlDataSource_grid" runat="server" ConnectionString="<%$ ConnectionStrings:DealCaptureDev %>" SelectCommand="sp_get_single_deal" SelectCommandType="StoredProcedure" UpdateCommand="Update trDealLeg Set PrimarySettlementPrice=@primarysettlement, AgreedSettlementprice=@agreedsettlement, LastUpdate=GetDate(), LastUpdateBy=Session('userid') Where LegID=@legid" EnableCaching="True" ConflictDetection="CompareAllValues" ProviderName="System.Data.SqlClient">
<SelectParameters>
<asp:QueryStringParameter DefaultValue="" Name="dealnum" QueryStringField="deal"
Type="String" />
</SelectParameters>
<UpdateParameters>
<asp:ControlParameter ControlID="txtLegId" PropertyName="Text" Name="legId" />
<asp:ControlParameter ControlID="txtPrimarySettlement" Name="primarysettlement" PropertyName="Text" />
<asp:ControlParameter ControlID="txtAgreedSettlement" Name="agreedsettlement" PropertyName="Text"/>
<asp:SessionParameter DefaultValue="" Name="userid" SessionField="userid" />
</UpdateParameters>
</asp:SqlDataSource>
As seen above, controls such as txtPrimarySettlement are referenced but the update is not successful. The text boxes are within the GridEditSettlement gridview. In the .aspx code I cannot use FindControl (at least I don't think it will work).
So the questions are: Is it possible to reference the child controls, if so - how? Is there another way to do this, such as in the vb code behind - in the either the gridview's RowUpdating event or the SQLDataSource's Updating event.
What is the best approach? Anyone come up against this issue before?
Thanks,

Hi,I have an updatable DataGrid linked to a SQLDataSource in a web site developed using VS2005. Update works fine unless a value in the existing row is Null. Only one column in the database allows nulls.Putting a debug stop in the SqlDataSource1_Updating event, I checked the parameter value in the Immediate window and got the following result:?e.Command.Parameters(16){System.Data.SqlClient.SqlParameter}System.Data.SqlClient.SqlParameter: {System.Data.SqlClient.SqlParameter}DbType: Int32 {11}Direction: Input {1}IsNullable: FalseParameterName: "@original_FiresolveJobNo"Size: 0SourceColumn: ""SourceColumnNullMapping: FalseSourceVersion: Current {512}Value: NothingIs there a property I can set to generate a suitable Null check clause for the Update statement?Many Thanks,Keith.

I can get it to fill with data by manually filling the GridView without using a SqlDataSource but then I cannot get the sorting to work when I do it that way. Actually not sure if the sorting will work this way either as I cannot get it to fill with data. Any ideas would be much appreciated.

Hello.When I create a user at the ASP.NET database, I need to insert more fields than the defaults, and I do it like this: Dim customProfile As ProfileCommon = ProfileCommon.Create(CreateUserWizard1.UserName, True)
customProfile.telephone =
(CType(CreateUserWizard1.CreateUserStep.ContentTemplateContainer.FindControl("TelephoneText"),
TextBox)).Text(telephone example)Those data are inserted at the DB at the aspnet_Profile table, in the fields PropertyNames & PropertyValuesString, but they are saved together (see image above)
I want to separate those properties in the GridView as long as each property appears in a column, is it possible? Thank you very much, i'm expecting your answers.

Ok, this seems really straightforward, but I'm completely lost. I created a sqldatasource control that uses an INSERT stored procedure. I can click on test it tests just fine, inserts everything into the database.Now, I want this sqldatasource control to fire when a button is clicked, but I have no idea how to do this, I looked at the parameters and cant find an execute or anything like that to use. Let me know how to execute this sqldatasource, it'd really help me out. I know you can do EVERYTHING in the code behind file, but I'm rather new to VB and I'm probably gonna save that for another day. Here's what I have now:basic sqldatasource : <asp:SqlDataSource ID="SqlProcDS" runat="server" ConnectionString="<%$ ConnectionStrings:pubsConnectionString %>" InsertCommand="ins_test" InsertCommandType="StoredProcedure" SelectCommand="ins_test" SelectCommandType="StoredProcedure"> <SelectParameters> <asp:ControlParameter ControlID="TextBox1" Name="a" PropertyName="Text" Type="String" /> <asp:ControlParameter ControlID="TextBox2" Name="b" PropertyName="Text" Type="String" /> <asp:ControlParameter ControlID="TextBox3" Name="c" PropertyName="Text" Type="String" /> </SelectParameters> <InsertParameters> <asp:Parameter Name="a" Type="String" /> <asp:Parameter Name="b" Type="String" /> <asp:Parameter Name="c" Type="String" /> </InsertParameters> </asp:SqlDataSource>in the vb file : Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click 'Somehow execute sqlProcDS here?!End Sub

Hi
I have a gridview which is using a SQLdatasource, to update the table. One of my parameters on the SP is username.
At the moment on page load I am declaring a session variable
Session("UserName") = me.user.identy.name
I then amend the update parameter in the SQL Datasource to accept the username from the session variable. - works fine, I was however wondering if there is a way of returning the username directly into the sqldatasource without having to pass it through a session variable?
regards
Tom

Hi guys! I have a simple windows form where a gridview is being populated by a database. I have checked the ability to update, insert delete. And everything is fine but when i want to delete a row it throws an exeption. The exeptions says: "Must declare the scalar variable "@id"."I haven't changed the delete, update and insert commands. They are as fallowsDeleteCommand="DELETE FROM [recepti] WHERE [id] = @id"InsertCommand="INSERT INTO [recepti] ([ime], [recepta], [snimka], [snimka2], [tip]) VALUES (@ime, @recepta, @snimka, @snimka2, @tip)" SelectCommand="SELECT * FROM [recepti]"UpdateCommand="UPDATE [recepti] SET [ime] = @ime, [recepta] = @recepta, [snimka] = @snimka, [snimka2] = @snimka2, [tip] = @tip WHERE [id] = @id" The id column is auto generated, unique, also it's a primery key.So any idea where is the problem?

Hi,I have two SQLDataSources called "LeagueTableHome" an "LeagueTableAway" on my page.
I want to create another SQLDataSource called "LeagueTableTotal" on my page which adds up all the totals from each of the other two sources.
The datasource looks like this:
Team, Pld, W, D, L, F, A, Agg, Pts
my code for LeagueTableHome looks like this:
SELECT HomeTeam, 1 AS Pld, CASE WHEN HomeScore > AwayScore THEN 1 ELSE 0 END AS Won, CASE WHEN HomeScore = AwayScore THEN 1 ELSE 0 END AS Draw, CASE WHEN HomeScore < AwayScore THEN 1 ELSE 0 END AS Lost, HomeScore AS Scored, AwayScore AS Against, HomeScore - AwayScore AS Agg, CASE WHEN HomeScore > AwayScore THEN 3 ELSE 0 END AS Pts FROM tblFixtures WHERE (CompID = 1) AND (HomeScore IS NOT NULL)
I want then to show LeagueTableTotal in a GridView.
Can anybody help?

I cant seen to change the Select command for a SQL Datasourcetry #1 SqlDataSourceProfilesThatMatch.SelectCommand = strSQLForSearch SqlDataSourceProfilesThatMatch.SelectParameters("ProfileID").DefaultValue = pProfileID SqlDataSourceProfilesThatMatch.SelectParameters("LoggedInUsersZipcode").DefaultValue = pUsersZipCode SqlDataSourceProfilesThatMatch.SelectParameters("ZipDistance").DefaultValue = pDistance
NewProfilesThatMatchGridView.DataBind()
try #2 SqlDataSourceProfilesToBeMatched.SelectParameters.Clear() SqlDataSourceProfilesThatMatch.SelectCommand = strSQLForSearch SqlDataSourceProfilesThatMatch.SelectParameters.Add("ProfileID", pProfileID) SqlDataSourceProfilesThatMatch.SelectParameters.Add("LoggedInUsersZipcode", pUsersZipCode) SqlDataSourceProfilesThatMatch.SelectParameters.Add("ZipDistance", pDistance)
NewProfilesThatMatchGridView.DataBind()
No errors but no rows show in the gridview. If I debug and get the value strSQLForSearch and paste it into a new SQL query window I get results.
Any ideas????

Hello
I'm experiencing some problems, binding a SqlDataSource to a GridView.
The following code creates the SqlDataSource: string strConn = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString; string strProvider = ConfigurationManager.ConnectionStrings["ConnectionString"].ProviderName; SqlDataSource ds = new SqlDataSource(strProvider, strConn); ds.SelectCommand = "SELECT * FROM rammekategori";
Then i bind the SqlDataSource to a GridView:
GridView1.DataSource = ds; GridView1.DataBind();
ErrorMessage:
Format of the initialization string does not conform to specification starting at index 0.
Exception Details: System.ArgumentException: Format of the initialization string does not conform to specification starting at index 0.Line 24: GridView1.DataBind();Am i totally off target here? Can it be something about, that you have to set the datasource of the gridview, before the Page_Load event?
Thanks - MartinHN

Hi, I'm new in ASP 2.0. I need to incorporate edit and delete capability in GridView. Using the wizard, i've generated this code. When I delete a row, it gets deleted but update does not work. I've tried several ways. I got no error or exception. But row is not updated. I've checked database, and I think the update query is not executing at all. Please let me know, what I'm doing wrong? Here is the source code for reference. I'm using Visual Studio 2005 with SQL server 2005 Express Edition. Regards
==========================================================
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="QuoteItemID" DataSourceID="SqlDataSource1"> <Columns> <asp:CommandField ShowDeleteButton="True" ShowEditButton="True" CausesValidation="False" /> <asp:BoundField DataField="QuoteItemID" HeaderText="QuoteItemID" InsertVisible="False" ReadOnly="True" SortExpression="QuoteItemID" /> <asp:BoundField DataField="QuoteID" HeaderText="QuoteID" SortExpression="QuoteID" /> <asp:BoundField DataField="ChargeCodeID" HeaderText="ChargeCodeID" SortExpression="ChargeCodeID" /> <asp:BoundField DataField="RateItemAmount" HeaderText="RateItemAmount" SortExpression="RateItemAmount" /> </Columns> </asp:GridView> <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ratesdb %>" DeleteCommand="DELETE FROM [Quote_item] WHERE [QuoteItemID] = @QuoteItemID" InsertCommand="INSERT INTO [Quote_item] ([QuoteID], [ChargeCodeID], [RateItemAmount]) VALUES (@QuoteID, @ChargeCodeID, @RateItemAmount)" SelectCommand="SELECT * FROM [Quote_item]" UpdateCommand="UPDATE [Quote_item] SET [QuoteID] = @QuoteID, [ChargeCodeID] = @ChargeCodeID, [RateItemAmount] = @RateItemAmount WHERE [QuoteItemID] = @QuoteItemID" ConflictDetection="CompareAllValues"> <DeleteParameters> <asp:Parameter Name="QuoteItemID" Type="Int32" /> </DeleteParameters> <UpdateParameters> <asp:Parameter Name="QuoteID" Type="Int32" /> <asp:Parameter Name="ChargeCodeID" Type="Int32" /> <asp:Parameter Name="RateItemAmount" Type="Decimal" /> <asp:Parameter Name="QuoteItemID" Type="Int32" /> </UpdateParameters> <InsertParameters> <asp:Parameter Name="QuoteID" Type="Int32" /> <asp:Parameter Name="ChargeCodeID" Type="Int32" /> <asp:Parameter Name="RateItemAmount" Type="Decimal" /> </InsertParameters> </asp:SqlDataSource>

I have a SqlDataSource that I need to remove the first 3 rows from before it is bound to a GridView. How would I go about doing this?
(if I could remove them at the db level in the sproc I would, but right now that is not an option - so I need to do it once I've already received the data)
Thanks.

Hi,
I have a GridView connected to a sqldatasource control. Everything is working great, updates, paging and filtering with one exception. When the user enters in a name like O'Reilly (with a single quote), the page errors. The error returned is:
Syntax error: Missing operand after 'Reilly' operator.
Here is the definition of the sqldatasource:
<asp:SqlDataSource ID="SqlDataSourcePersons" runat="server" ConnectionString="<%$ ConnectionStrings:database %>" SelectCommand="SELECT [Id], [FirstName], [LastName], , [PersonTypeId], [WorkerId], [_workerNTId], [Title], [City] FROM [Person]" FilterExpression="(FirstName like '{0}%') AND (LastName like '{1}%') AND (WorkerId like '{2}%') AND (City like '{3}%')" ProviderName="System.Data.SqlClient"> <FilterParameters> <asp:ControlParameter ControlID="TextBoxFirstName" Name="FirstName" DefaultValue="%" PropertyName="Text" Type="String" /> <asp:ControlParameter ControlID="TextBoxLastName" Name="LastName" DefaultValue="%" PropertyName="Text" Type="String" /> <asp:ControlParameter ControlID="TextBoxWorkerId" Name="WorkerId" DefaultValue="%" PropertyName="Text" Type="String" /> <asp:ControlParameter ControlID="TextBoxCity" Name="City" DefaultValue="%" PropertyName="Text" Type="String" /> </FilterParameters> </asp:SqlDataSource>
Any suggestions would be appreciated.
Thank you, Jim

Hi all, first post, and I am desperate.
I have a SqlDataSource with a Select, Update and Delete command. From what I understand, scalar variables should be read automatically from the GridView's BoundField columns when it executes a command on it. Here is my code:
<asp:GridView
ID="teamGrid"
EmptyDataText="n/a"
DataKeyNames="TeamId"
AutoGenerateColumns="false"
DataSourceID="teamSource"
OnRowEditing="validateEdit"
OnRowDeleting="validateDelete"
runat="server">
<Columns>
<asp:CheckBoxField DataField="TeamApproved" HeaderText="Approved" />
<asp:BoundField DataField="TeamName" HeaderText="Team Name" />
<asp:TemplateField HeaderText="City">
<ItemTemplate>
<asp:Label runat="server"><%# Eval("City") %></asp:Label>, <asp:Label runat="server"><%# Eval("ProvinceCode") %></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="RequestedDivision" HeaderText="Division Req." ControlStyle-Width="60px" />
<asp:BoundField DataField="DivisionCode" HeaderText="Assigned Division" ControlStyle-Width="60px" ConvertEmptyStringToNull="true" NullDisplayText="n/a" />
<asp:BoundField DataField="DivisionNumber" HeaderText="Division Number" ControlStyle-Width="60px" ConvertEmptyStringToNull="true" NullDisplayText="n/a" />
<asp:BoundField DataField="Password" HeaderText="Password" ConvertEmptyStringToNull="true" NullDisplayText="n/a" />
<asp:CheckBoxField DataField="Paid" HeaderText="Paid" />
<asp:HyperLinkField Text="view players" ItemStyle-Width="70px" ItemStyle-HorizontalAlign="Center" DataNavigateUrlFields="TeamId" DataNavigateUrlFormatString="viewTeamPlayers.aspx?teamId={0}" ShowHeader="false" />
<asp:CommandField ItemStyle-HorizontalAlign="Center" ItemStyle-Width="30px" ButtonType="Link" EditText="edit" ShowEditButton="true" ShowHeader="false" />
<asp:TemplateField ShowHeader="False" ItemStyle-HorizontalAlign="Center" ItemStyle-Width="30px">
<ItemTemplate>
<asp:LinkButton runat="server" CausesValidation="False" CommandName="Delete" OnClientClick='return confirm("Deleting this team will also delete the players. Are you sure you wish to continue?");' Text="delete" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
<asp:SqlDataSource
ID="teamSource"
ConnectionString="<%$ ConnectionStrings:MB %>"
SelectCommand="SELECT TeamId, TeamName, ProvinceCode, City, DivisionCode, DivisionNumber, TeamApproved, RequestedDivision, Paid, Password, CaptainId, Player2Id, Player3Id, Player4Id FROM [Team]"
UpdateCommand="UPDATE [Team] SET TeamName = @TeamName, DivisionCode = @DivisionCode, DivisionNumber = @DivisionNumber, TeamApproved = @TeamApproved, Paid = @Paid, Password = @Password WHERE TeamId = @TeamId"
runat="server" />
</form>
I apologize for the way the code is put in, the code thing cut off a lot of the text! The problem I'm getting is, when the 'Update' button is hit, I get the error: Must declare the variable '@TeamId'.
I've tried putting "Update Parameters", that takes away the error, but the row does not update. I've browsed the internet and saw the same problems in lots of areas, but either a) none of the solutions work for me, or b) they don't really apply to my case.
I'm using ASP .NET 2.0, and (obviously) C#. SQL Server database.
Any help is greatly appreciated. Thanks in advance,
- Branden

hello all
1) I was using SQLdataSource and bind it with the gridviw to show its data. so that is how is running
when the page load, i see the data is posted on the page on the gridview.
But what i need to do when I want a user to click a button and then the Gridview show the data.
As i was creating a SQLDatasource, it was click click and click but I want to put that sqldatasouce to load the data in gridview by a click event.
2) my second question is also related to the first one or just similar.
I dont want to get all the data rather filter it.
so once the page load, there is a button and a text box.
In the text box user going to type the EmployeeID and click the "Employee Info" button and then the data would show up.
Rather i use te DetaildView Control . What should I do to load the information on the Text boxes rather then on the GridView since it is going to be a single recrod.
Thanks all

There are so many ways to use database in asp.net/ado.net, I'm a bit confused about their difference from the performance point of view.So apparently SqlDataSource in DataReader mode is faster than DataSet mode, at a cost of losing some bolt-on builtin functions.What about SqlDataSource in DataReader mode vs manual binding in code? Say creating a SqlDataSource ds1 and set "DataSourceID" in Gridview, vs manually creating the SqlConnection, SqlCommand, SqlDataReader objects and mannually bind the myReader object to the gridview with the Bind() method.Also Gridview is a very convenient control for many basic tasks. But for more complex scenarios it requires lots of customization and modification. Now if I do not use gridview at all and build the entire thing from scratch with basic web controls such as table and label controls, and mannually read and display everything from a DataReader object, how's the performance would be like compared to the Gridview-databind route?

Hi,
I think the title explains it all really. I cannot configure the SqlDataSource to add Insert, Update and Delete statements - not through the wizard anyway.
The view combines two tables, each containing 3 columns. I have tried using different combinations of columns, and ended up selecting all of them (making sure the foreign key column of the first table was given a different alias to the primary key column of the second table) but I still cannot enable editing.
Cheers,
Patrick
