Sqldatasource.updatecommand

May 11, 2006

I have a SQLDataSource that has an UpdateCommand assigned to it.  At certain times I may need to change the UpdateCommand to save different info to the database.  I thought I would be able to use sqldatasource.updatecommand.equals() to change the UpdateCommand and then call the sqldatasource.update method, but it didn't work...the default command was still used.  Is there something else I need to change?  I figured my next option would be to create another sqldatasource.  Any help would be great!

UpdateCommand For SQLDataSource

Apr 13, 2007

I have a custom setup so bear with me here in my explanation.  The SelectCommand for my SQLDataSource gets data from a table using a QueryString for filtering by the record ID. A Repeater control is then used to populate the data into different Textboxes on the page (and a custom HTML-editor control). This works 100%.  I'm trying to use the UpdateCommand for the SQLDataSource to then update the record with the data that the user changes. (Example: FieldA is "foo" and the user changes it to "foobar". When the form is submitted, it then updates FieldB to be "foobar").  The form is being submitted, but the data isn't being updated at all.  Any ideas? Thanks for the help in advance.

Hello all,
I am trying to update the record which involed the modification of key in Datakeynames, but when i click the update button from gridview, it doesn't allow to change the value of modified column.
<asp:SqlDataSource ID="SqlDataSource1" runat="server" DataSourceMode="DataSet"                 ConnectionString="<%$ ConnectionStrings:WebsiteDataConnection %>" OldValuesParameterFormatString="old_{0}"                SelectCommand="SELECT * FROM [ServiceAgents]"                InsertCommand="INSERT INTO ServiceAgents VALUES(@Ser_STATE, @Ser_CITY, @Ser_AGENT, @Ser_PHONE, @Ser_EQUIPMENT)"                UpdateCommand="UPDATE ServiceAgents SET AGENT=@AGENT, PHONE=@PHONE WHERE (STATE=@STATE and CITY=@CITY and AGENT=@old_AGENT and EQUIPMENT=@EQUIPMENT)"                DeleteCommand="DELETE FROM ServiceAgents WHERE (STATE=@STATE and CITY=@CITY and AGENT=@AGENT and EQUIPMENT=@EQUIPMENT)" >                                <UpdateParameters>                    <asp:Parameter Type="String" Name="AGENT" />                    <asp:Parameter Type="String" Name="PHONE" />                                         <asp:Parameter Name="old_AGENT" />                    <asp:Parameter Type="String" Name="STATE" />                    <asp:Parameter Type="String" Name="CITY" />                    <asp:Parameter Type="String" Name="EQUIPMENT" />                </UpdateParameters>                                <InsertParameters>                    <asp:ControlParameter Name="Ser_STATE" ControlID="TextBox_state"/>                    <asp:ControlParameter Name="Ser_CITY" ControlID="TextBox_city"/>                    <asp:ControlParameter Name="Ser_AGENT" ControlID="TextBox_agent"/>                    <asp:ControlParameter Name="Ser_PHONE" ControlID="TextBox_phone"/>                    <asp:ControlParameter Name="Ser_EQUIPMENT" ControlID="TextBox_equip" />                   </InsertParameters>                                <DeleteParameters>                   <asp:Parameter Type="String" Name="STATE" />                    <asp:Parameter Type="String" Name="CITY" />                    <asp:Parameter Type="String" Name="AGENT" />                    <asp:Parameter Type="String" Name="EQUIPMENT" />                </DeleteParameters>                            </asp:SqlDataSource>

SqlDataSource && DetailsView UpdateCommand

Mar 6, 2006

Hi
I have a Page with a DetailsView and SqlDataSource. When Editing the DetailsView the Sql;DataSource UpdateCommand does not seem to pick up the @parameters of the form fields. I have used OnItemUpdating to view all Keys/OldValues/NewValues passed into the UpdateCommand but nothing seems to be picked up.
When I place a value into UpdateCommand it updates correctly but does not when I use the form. At this stage I have simplified the code down to typical Master-Details Pages (Separate) using a QueryString to filter the SelectCommand. But nothing seems to work.
Please help! I have wasted so much time trying to resolve this and I am on deadline and need this to work.
Thanks
Dave

SQLDataSource: Update 2 Tables With 1 UpdateCommand?

Mar 16, 2007

I have a Gridview (edit enabled), connected to a SQLDataSource.
 SQLDataSource populates the gridview from 1 SelectCommand.
 figure1:
ColumnA | ColumnB | ColumnC
 
I have 2 SQL Server 2005 tables: Table1 and Table2 
Now on my SQLDataSource's UpdateCommand, I want the value of ColumnB to go to Table1's ColumnB, and ColumnC to go to Table2's ColumnC.
How do I do this?
I understand I can't do this with 1 UPDATE-SET sql query. Maybe I can with stored procs or something, but im kinda noobish when it comes to this. How? Thanks

How To Programmatically Construct The UpdateCommand For SqlDataSource

Aug 1, 2007

Hi, All
I'm using Gridview and SqlDataSource to dynamically display the contents in different tables, as followed:
<%   dataSource.ConnectionString = System.Configuration.ConfigurationSettings.AppSettings["connectionString"];   dataSource.SelectCommand = "SELECT * FROM " + tableName;   gridView.DataBind();
   dataSource.UpdateCommand = "";%>
<asp:SqlDataSource ID="dataSource" runat="server"></asp:SqlDataSource><asp:GridView ID="gridView" runat="server" DataSourceID="dataSource" AllowPaging="True" AllowSorting="True" AutoGenerateEditButton="True" BorderColor="Silver" BorderStyle="Solid" BorderWidth="1px" CellPadding="3" PageSize="20" DataKeyNames="ID" OnRowDataBound="tableGridView_RowDataBound">    <HeaderStyle BackColor="#C0C0FF" />    <AlternatingRowStyle BackColor="#C0FFC0" /></asp:GridView>
The datasource take the "tableName" as argument to determine which table to display. My problem is I can't figure out a way to programmatically construct the UpdataCommand for the SqlDataSource. I try to get the field names from the HeaderRow, but all the cells are empty in this row.
Does anyone know what causes the problem or how to construct the UpdateCommand properly. Thanks!

GridView Update, With SqlDataSource UpdateCommand Set From Code-behind. (C#)

Mar 9, 2006

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

Have A Problem With UpdateCommand

Dec 28, 2006

Hello everyone,
 I am a bit new to ASP .Net so forgive me, if I dont understand something right off.
I am writing a page that gets code from the SQL database and puts it into a GridView. To get the information I am using SqlDataSource. I cant post an error message because I am running this off remote server but though testing I figure that it crashes when I add
Analysis = @Analysis
line into the UpdateCommand. First I thought that maybe my parameters were not read correcty but when I tried something like
Analysis  = 6
it worked. Then I tried to replace CQNo=@CQNo with
CQNo = @Analysis
and it also worked.
 I am very much puzzed at this. In SQL database CQNo is varchar, WorkDate is DateTime and Analysis is Money type.
 Can someone please help, I am out of ideas. Thanks!
<asp:SqlDataSource ID="myEfforts" runat="server"
SelectCommand="SELECT SNo, CQNo, WorkDate, Analysis, Design, Coding, Testing, DesRev, CodeRev, PeerRev, SysTest, PostInstall, Others, TotEff FROM Effort WHERE EmpId = @EmpId ORDER BY WorkDate DESC"
DeleteCommand="DELETE FROM Effort WHERE SNo=@SNo"
UpdateCommand="UPDATE Effort SET CQNo = @CQNo, WorkDate=@WorkDate Analysis=@Analysis WHERE SNo=@SNo">
<SelectParameters>
<asp:SessionParameter DefaultValue="" Name="EmpId" SessionField="PR_EmpIDVal" Type="String" />
</SelectParameters>

Manipulating A SqlDatSource UpdateCommand In Code-behind

Jul 20, 2007

We've got an employee database that I'm modifying to include two photos of each employee, a small thumbnail image and a full-size image.  The HR department maintenance page contains a listbox of employee names, which, when clicked, populates a detailsview control.To get the images to display and be updatable, I've had to structure the following SqlDatasource and DetailsView:
1    <asp:DetailsView ID="dvEmp" runat="server"2      AutoGenerateRows="false"3      DataSourceID="dsEmpView"4      DataKeyNames="empID">5    <Fields>6    <asp:CommandField ShowEditButton="true" ShowCancelButton="true" ShowInsertButton="true" />7    <asp:BoundField HeaderText="Name (Last, First)" DataField="empname" />8    <asp:TemplateField HeaderText="Thumbnail photo">9    <ItemTemplate>10   <asp:Image ID="imgThumbnail" runat="server" ImageUrl='<%# formatThumbURL(DataBinder.Eval(Container.DataItem,"empID")) %>' />11   </ItemTemplate>12   <EditItemTemplate>13   <asp:Image ID="imgThumbHidden" runat="server" ImageUrl='<%# Bind("thumbURL") %>' Visible="false" />14   <asp:FileUpload ID="upldThumbnail" runat="server" />15   </EditItemTemplate>16   </asp:TemplateField>17   <asp:TemplateField HeaderText="Full Photo">18   <ItemTemplate>19   <asp:Image ID="imgPhoto" runat="server" ImageUrl='<%# formatImageURL(DataBinder.Eval(Container.DataItem,"empID")) %>'  />20   </ItemTemplate>21   <EditItemTemplate>22   <asp:Image ID="imgPhotoHidden" runat="server" ImageUrl='<%# Bind("photoURL") %>' Visible="false" />23   <asp:FileUpload ID="upldPhoto" runat="server" />24   </EditItemTemplate>25   </asp:TemplateField>26   </Fields>27   </asp:DetailsView>28   29   <asp:SqlDataSource ID="dsEmpView"30     runat="server"31     ConnectionString="<%$ ConnectionStrings:eSignInConnectionString %>"32     OnInserting="dsEmpView_Inserting"33     OnUpdating="dsEmpView_Updating"34     SelectCommand="SELECT empID, empname, photoURL, thumbURL FROM employees where (empID = @empID)"35     InsertCommand="INSERT INTO employees (empname, photoURL, thumbURL) values(@empname, @photoURL, @thumbURL)"36     UpdateCommand="UPDATE employees SET empname=@empname, photoURL=@photoURL, thumbURL=@thumbURL WHERE (empID = @empID)">37     <SelectParameters>38       <asp:ControlParameter ControlID="lbxEmps" Name="empID" PropertyName="SelectedValue" Type="Int16" />39     </SelectParameters>40   </asp:SqlDataSource>41   42   -----43   44   Protected Sub dsEmpView_Updating(ByVal sender As Object, ByVal e As SqlDataSourceCommandEventArgs)45     Dim bAbort As Boolean = False46     Dim bThumb(), bPhoto() As Byte47     If e.Command.Parameters("@ename").Value.trim = "" Then bAbort = True48     Dim imgT As FileUpload = CType(dvEmp.FindControl("upldThumbnail"), FileUpload)49     If imgT.HasFile Then50       Using reader As BinaryReader = New BinaryReader(imgT.PostedFile.InputStream)51         bThumb = reader.ReadBytes(imgT.PostedFile.ContentLength)52         e.Command.Parameters("@thumbURL").Value = bThumb53       End Using54     End If55     Dim imgP As FileUpload = CType(dvEmp.FindControl("upldPhoto"), FileUpload)56     If imgP.HasFile Then57       Using reader As BinaryReader = New BinaryReader(imgP.PostedFile.InputStream)58         bPhoto = reader.ReadBytes(imgP.PostedFile.ContentLength)59         e.Command.Parameters("@photoURL").Value = bPhoto60       End Using61     End If62     e.Cancel = bAbort63   End SubIf the user updates both images at the same time by populating their respective FileUpload boxes, everything works as advertized.  But if the user only updates one image (or neither image), things break. If they upload, say, just the full-size photo during an update, then it gives the error "System.Data.SqlClient.SqlException: Operand type clash: nvarchar is incompatible with image".I think this error occurs because the update command is trying to set the parameter "thumbURL" without having any actual data to set.  But since I really don't want this image updated with nothing, thereby erasingthe photo already in the database, I'd rather remove this parameter from the update string.So, let's remove the parameter that updates that image by adding the following code just after the "End Using" lines: Else
Dim p As SqlClient.SqlParameter = New SqlClient.SqlParameter("@thumbURL", SqlDbType.Image)
e.Command.Parameters.Remove(p)
(Similar code goes into the code block that handles the photo upload)Running the same update without an image in the thumb fileupload box, I now get this error: "System.ArgumentException: Attempted to remove an SqlParameter that is not contained by this SqlParameterCollection."Huh?  It's not there?  Okay, so lets work it from the other end: let's remove all references to the thumbURL and photoURL from the dsEmpView datasource.  We'll make its UpdateCommand = "UPDATE employees SET empname=@empname WHERE (empID = @empID)", and put code in the dsEmpView_Updating sub that adds the correct parameter to the update command, but only if the fileupload box has something in it.  Therefore: If imgT.HasFile Then
Using reader As BinaryReader = New BinaryReader(imgT.PostedFile.InputStream)
bThumb = reader.ReadBytes(imgT.PostedFile.ContentLength)
e.Command.Parameters.Add(New SqlClient.SqlParameter("@thumbURL", SqlDbType.Image, imgT.PostedFile.ContentLength))
e.Command.Parameters("@thumbURL").Value = bThumb
End Using
End If
(Similar code goes into the code block that handles the photo upload)But reversing the angle of attack only reverses the error. Uploading only the photo and not the thumb image results in: "System.Data.SqlClient.SqlException: The variable name '@photoURL' has already been declared. Variable names must be unique within a query batch or stored procedure."So now it's telling me the parameter IS there, even though I just removed it.ARRRGH!What am I doing wrong, and more importantly, how can I fix it?Thanks in advance.

Dynamic SQL Generation For The UpdateCommand Is Not Supported

Nov 7, 2007

Dynamic SQL generation for the UpdateCommand is not supported against a SelectCommand that does not return any key column information.

I am getting the above error if i try to create a update command through a Command builder in .net cf on a SQLCE 3.0 database

The Select query I used for creating the update command is 'SELECT * FROM Users'


I populated a datatable with the above query through a DataAdapter, to check for the primary key and the primary key was available in the table. But still the CB could not able to create an Update Command for that query,

The Primary Key column that I use is of type GUID

Then when try to do the above job using a Typed DataSet with TableAdapters , then it throws the following error

'Update requires a valid UpdateCommand when passed DataRow Collection with modified rows'

can any one please tell me a way to fix this ,

Thanks and Regards

SELECT A Single Row With One SqlDataSource, Then INSERT One Of The Fields Into Another SqlDataSource

Jul 23, 2007

What is the C# code I use to do this?
I'm guessing it should be fairly simple, as there is only one row selected. I just need to pull out a specific field from that row and then insert that value into a different SqlDataSource.

Sqldatasource

Jan 15, 2007

hi all,
in all my 2.0 learnings and books i keep coming across the page element <asp:sqldatasource>.
I have always (in 1.1) used server side connections and adapters to bind my Sql datasets to any control needed.  Now that im learning 2.0 im finding it difficult to understand using control on the page to bind my data.  Can someone explain the benefits of using this data source?  Ideally i would like to keep my data access layer separate from my presentation layer but i'd really like to understand why this method seems so popular.
thanks in advance,
mcm

Using SQLDataSource

Feb 23, 2007

Hi, I am new to ASP.NET 2.0 and I am trying to use VWB to bind my web site to a SQL Express edition. I used SQLDataSource to specify the .mdf file so I can connect to my tables but when I click on the advanced button to generate the Insert, Update, Delete SQL I find it grayed out and it cannot be clicked. I looked into several tutorials online and I couldn't find the problem, can anyone explain what I am missing or doing wrong? Any suggestion is very appreciated. Thanks

Using An SQLDataSource For Than Once

Aug 21, 2007

Hi,
I'm trying to go through a checkbox list and inserting them into a database using a sqldatasource with the following code:For Each li As ListItem In Locations_Checkbox.Items
If li.Selected = True Then
 
Dim DataSource2 As SqlDataSource = CType(InsertProgrammeLocations, SqlDataSource) DataSource2.InsertParameters.Add("ProgrammeID", li.Value)
DataSource2.Insert()
 
 
End If
Next
When more than one checkbox is ticked, I'm getting the error 'The variable name '@ProgrammeID' has already been declared'. How do I close or reset my Datasource before I try and use it again?
Thanks for your help

What Is SqlDataSource

Oct 29, 2007

Hi, I want to know when to use an sqlDataSource object because I used to populate for example a listBox control in visual studio net 2003 from AQLK server database by using a connection object, command object, dataAdapter object and a DataSet object. I discovered if I use sqlDataSource object (using visual studio net 2005) ,all I need is to write the connection string and a Select statement as properties for that sqlDataSource, so why to use the above mentioned objects(connection,command,adapter,dataset) while I can access any database in sql server through the use of sqlDataSource?
I appreciate if you can explain to me the difference and when to use an sqlDataSource
thx

Do You Really Use SqlDataSource?

Dec 9, 2007

Hi,
I have an application w/ n-tier design so I've never used the SqlDataSource up to this point but having to do my own sorting for GridViews is not something I want to keep dealing with. I'd like to take advantage of some of the packaged features too.
My question is: are there any purists out there who opted to use SqlDataSource. If so, what do you think about it? It's nice that SqlDataSource makes things simple but having data classes and dealing w/ exceptions in those classes certainly make an application pretty robust. Should I entertain the idea of using SqlDataSource or stay as a purist and keep doing things the old fashioned way?
