DetailsView Control (Please Help!!!!)
May 14, 2006
Can someone please tell me what I am doing wrong...
I have a simple webform that has contains a GridView and a DetailsView. Once the GridView is populated the user simply selects a record from the list. The DetailsView is them populated with all of the data from the selected record.
The DetailsView is bound to a SQL DataSource/CustomerData. I have made sure that the DV control has the Edit/Update Command listed. The user can click the Edit button and successfully edit the fields but when the user clicks the "Update" button I am getting the following message.
Updating is not supported by data source 'CustomerData' unless UpdateCommand is specified
Why isnt the control handling the Update.
Many Thanks!!!!

Hi all,I want to be able to implement what the following site shows in regards to dynamically displaying Data views of various types: http://quickstarts.asp.net/QuickStartv20/aspnet/samples/data/GridViewMasterDetails_vb.aspx I follow everything to the 'T' but for some reason all my data views are showing even before any initial selection is made in the drop down. How can I have certain grids appear only after a selection from another control has been made?Thanks in advance,Nick

I have 2 Gridviews and a DetailsView for each GridView. The first Gridview and DetailsView work fine and I can Insert, Delete and Update the DetailsView just fine. However the second Gridview/DetailsView will only let me Insert but not Delete or Update. When I click on the "Delete" button it just ignores me. If I do an "Edit", when I try to click on the "Update" button it is ignored again and I have to click on "Cancel". I don't get any error messages...
Anyone have an idea what might be wrong?

Hi,I am using detailsview to update my database and got a question regarding datetime format. Here is part of my code:
<asp:TemplateField HeaderText="Project Deadline">
<EditItemTemplate>
<asp:TextBox ID="txtDeadline_edit" runat="server" Text='<%# Bind("pro_app_deadline") %>'></asp:TextBox>
<asp:CompareValidator ID="txtDeadlineedit_validator" runat="server" ErrorMessage="Not a valid date format" ControlToValidate="txtDeadline_edit" Operator="DataTypeCheck" Type="Date"></asp:CompareValidator>
</EditItemTemplate>
<ItemTemplate><asp:Label ID="txtDeadline" runat="server" Text='<%# Eval("pro_app_deadline") %>'></asp:Label>
</ItemTemplate></asp:TemplateField>
Since the format of my parameter 'pro_app_deadline' is datetime, it get stored as YYYY-MM-DD hh:mm:ss in datebase. If I want to validate user's input like above way, it always fails since hh:mm:ss append to YYYY-MM-DD. My question is, is there some way I can avoid hh:mm:ss?
Thanks a lot!

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

Hi,I'm trying to create a registration page that I've divided into multiple pages (first page for basic details, next page for address, etc.). I insert the record in the first page, and update it in the other pages. I pass the newly created ID to the other pages using the Page.PreviousPage property. In the second page, I have the SqlDataSource configured as "SELECT * FROM [Table] WHERE ID = ?", and the UpdateCommand is "UPDATE .... WHERE ID = ?". In Page_Load, I am updating the SelectCommand to "SELECT ... WHERE ID = " & intID, and the UpdateCommand similarly. The I do a dtlsvw.Databind()But when I go to the next page (the newly created ID is being passed properly), the update doesn't do anything. The new record doesn't contain the values in the detailsview. Can somebody help me out? Thanks,Wild Thing

For some reason I can't make the stars align. Could someone spot the problem here? I'm looking to select the Identity of my last inserted record in the code behind my DetailsView. Here are the relavent bits:
Stored Procedure:ALTER PROCEDURE usp_EW_INSERTMajor
@StartDate datetime, @Finishdate datetime, @ProjectName nvarchar(1000), @WorkCell nvarchar(1000),
@JobName nvarchar(1000), @PartName nvarchar(1000), @StatusID int, @ResponsibleID int, @FacilityID int
AS
Set nocount on
DECLARE @ProjectID int
/*This saves the bits to the Project table*/
INSERT INTO EW_Project (ProjectTypeID,FacilityID,StartDate,FinishDate,Status,EmployeeID)
VALUES(1,@FacilityID,@StartDate,@FinishDate,@StatusID,@ResponsibleID)
/*This saves the bits to the Major table*/
SET @ProjectID = SCOPE_IDENTITY()
INSERT INTO EW_MajorBasic(ProjectID,ProjectName,WorkCell,JobName,PartName)
VALUES (@ProjectID,@Projectname,@WorkCell,@JobName,@PartName)
Set nocount off
SELECT @ProjectID as ProjectID
SQLDataSource<asp:SqlDataSource ID="ProjectData" runat="server" ConnectionString="<%$ ConnectionStrings:myConnectionString %>"
SelectCommand="usp_EW_GETMajorBasic"
SelectCommandType="StoredProcedure"
UpdateCommand="usp_EW_UPDATEMajorBasic"
InsertCommand="usp_EW_INSERTMajor"
InsertCommandType="StoredProcedure"
UpdateCommandType="StoredProcedure"
DeleteCommand="DELETE FROM EW_Project WHERE ProjectID = @ProjectID"
>
<UpdateParameters>

<asp:Parameter Name="StartDate" Type="DateTime" />
<asp:Parameter Name="Finishdate" Type="DateTime" />
<asp:Parameter Name="ProjectName" Type="String" />
<asp:Parameter Name="WorkCell" Type="String" />
<asp:Parameter Name="JobName" Type="String" />
<asp:Parameter Name="PartName" Type="String" />
<asp:Parameter Name="StatusID" Type="Int32" />
<asp:Parameter Name="ResponsibleID" Type="Int32" />
<asp:CookieParameter CookieName="EW_FacilityID" Name="FacilityID" />
</UpdateParameters>
<InsertParameters>
<asp:Parameter Name="StartDate" Type="DateTime" />

OnItemInserted="DetailsView1_ItemInserted">
Code-Behind: Sub DetailsView1_ItemInserted(ByVal sender As Object, ByVal e As DetailsViewInsertedEventArgs) Handles DetailsView1.ItemInserted
Dim newID As Integer = e.Values("ProjectID")
testlabel.Text = newID
End Sub
To be clear, everything is working. When I come to this page with an ID, the records display fine (Select works). The Update and Delete work just fine. The Insert works fine too. It's just that the ItemInserted part does not want to grab the ProjectID. Specifically, testlabel displays a Zero.

I have been stuck on this problem for over a week, and have ripped out about all of my hair, so here it goes.
I am working on a portfolio on a website that administrators are allowed to update, but the public may only view....easy enough? The grid has three parameters; CatID, Descrip, and Pic - as seen below.
<asp:SqlDataSource ID="SqlDataSource2" runat="server"
ConnectionString="<%$ ConnectionStrings:NORTHWNDConnectionString %>"
SelectCommand="SELECT [CatID], [Descrip], [Pic] FROM [Categories]"
UpdateCommand="UPDATE Categories SET Descrip = @Descrip, Pic = @Pic WHERE CatID = @CatID"
DeleteCommand="DELETE FROM Categories WHERE CatID = @CatID"
InsertCommand="INSERT INTO [Categories] ([CatID], [Descrip], [Pic]) VALUES (@CatID, @Descrip, @Pic)" >
<DeleteParameters>
<asp:Parameter Name="CatID" Type="String" />
<asp:parameter Name="Descrip" />
</DeleteParameters>
<UpdateParameters>
<asp:parameter Name="Descrip" />
<asp:parameter Name="Pic" />
<asp:parameter Name="CatID" Type="String" />
</UpdateParameters>
<insertparameters>
<asp:parameter Name="CatID" Type="String" />
<asp:parameter Name="Descrip" Type="String" />
<asp:parameter Name="Pic" Type="String"/>
</insertparameters>
</asp:SqlDataSource>
The first this I am not sure of, is whether Pic should be a String or not.
Basically I am using Detailsview for the administrator to update, and the gridview for the public view.
<asp:DetailsView ID="DetailsView1" runat="server" AllowPaging="True"
AutoGenerateRows="False" DataKeyNames="CatID" HeaderText = "Portfolio"
DataSourceID="SqlDataSource2" Height="50px"
Width="300px" Font-Size = "14px" HeaderStyle-Font-Size="Larger" HeaderStyle-BackColor ="#27437D" HeaderStyle-ForeColor = "White"

<asp:boundfield DataField="CatID" HeaderText="Building/Job Name" ReadOnly="True" SortExpression="CatID">
</asp:boundfield>
<asp:boundfield DataField="Descrip" HeaderText="Description" SortExpression="CompanyName">
</asp:boundfield>
<asp:TemplateField HeaderText="Picture">
<EditItemTemplate>
<asp:TextBox ID="TextBox1" runat="server" Text='<%#Eval("Pic")%>' ></asp:TextBox>
</EditItemTemplate>
<InsertItemTemplate>
<asp:TextBox ID="TextBox1" runat="server" Text='<%#Eval("Pic")%>' ></asp:TextBox>
</InsertItemTemplate>
<ItemTemplate>
<asp:Image ID="Image1" runat="server" ImageUrl='<%# Eval("Pic") %>' />
</ItemTemplate>
</asp:TemplateField>
<asp:commandfield ShowDeleteButton="True" ShowEditButton="True" ShowInsertButton="True">
</asp:commandfield>
</Fields>
<HeaderStyle BackColor="#27437D" Font-Size="Larger" ForeColor="White"></HeaderStyle>
<alternatingrowstyle backcolor="#DCDCDC" />
</asp:DetailsView>
And my Gridview...
<asp:GridView ID= "GridView1" runat="server" DataSourceID="SqlDataSource2" AllowSorting="True" BackColor="White" CellPadding="3" Caption = "Portfolio"
Font-Size ="14px" BorderColor="#999999"BorderStyle="None"BorderWidth="1px"GridLines="Vertical"AutoGenerateColumns="False">
<FooterStyle BackColor="#CCCCCC" ForeColor="Black" />
<RowStyle BackColor="#EEEEEE" Font-Size = "Small" ForeColor="Black" />
<columns>
<asp:boundfield DataField="CatID" HeaderText="Building/Job Name"></asp:boundfield>
<asp:boundfield DataField="Descrip" HeaderText="Description"></asp:boundfield>
<asp:TemplateField HeaderText="Picture">
<EditItemTemplate>
<asp:TextBox ID="TextBox1" runat="server" text='<%# Eval("Pic") %>'
></asp:TextBox>
</EditItemTemplate>
<ItemTemplate>
<asp:Image ID="Image1" runat="server" ImageUrl= '<%# Eval("Pic") %>' />
</ItemTemplate>
</asp:TemplateField>
</columns>
<PagerStyle BackColor="#999999" ForeColor="Black" HorizontalAlign="Center" />
<SelectedRowStyle BackColor="#008A8C" Font-Bold="True" ForeColor="White" />
<HeaderStyle BackColor="#27437D" Font-Bold="True" ForeColor="White" />
<AlternatingRowStyle BackColor="#DCDCDC" />
</asp:GridView>
Now as I was looking around on the web I saw many people converting the path of the image to binary and the casting it to the DB, and likewise retrieving it from the DB as binary and converting it to an image, the problem is, I don't know how to do this.
Any help to ease my troubles is apprechiated greatly.
Edit: Also I am not totally sure what the '<%Eval("Pic") %>' is doing, it was autofilled for me.
Edit again: Another thing, if I replace any of the ImageUrl to an image path on the computer it does fill the space in the gridview/detailsview. However, with both cases I get a Operand type clash: nvarchar is incompatible with image error.

I have a SQLDataSource bound to a DetailsView. In which event would I catch a Primary Key violation? Would be an event of the SQLDataSource or the DetailsView? And which particular event? A small example would be great. Thx.

Hi all,We're selecting data from our database, FirstName, LastName, MobileNumber etc.We're using the detaials view function to return it in a table upon selection. However all of the variables are returned as they are in the database, ie: without spaces. We tried putting in spaces by selecting "AS what ever", but MSSQL does not seem to like spaces.Any ideas?Thanks

I am attempting to setup a Master-Details with GridView/DetailsView but I can't seem to find any information on using a stored procedure that requires parameters with the SqlDataSource control. SelectCommandType specifies that you are using a stored proc. SelectCommand specifies the name of the proc, but I haven't found any information on how to pass a parameter to the stored procedure.Is it even possible or do I have to forget about using the DetailsView control altogether?

I've been playing around with the new data controls (DetailsView,FormView) and have been having problems when attempting to update a record that has a uniqueidentifier as its primary key.I get the error message:
Object must implement IConvertible. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.InvalidCastException: Object must implement IConvertible.I gather this is because there is a bug that has propagated from the beta version.One suggested work around is from http://64.233.183.104/search?q=cache:GDjA62POtgcJ:scottonwriting.net/sowBlog/archive/11162005.aspx+Implicit+conversion+from+data+type+sql_variant+to+uniqueidentifier+is+not+allowed.+Use+the+CONVERT+function+to+run+this+query.&hl=en
The crux of the problem, it appears, is that the <asp:Parameter> value for the uniqueidentifier field is, by default, set to Type=�Object�. To fix this, simply remove the Type property altogether. That is, change the SqlDataSource parameter setting from something like:
<asp:SqlDataSource ...> <InsertParameters> <asp:Parameter Name=�UserId� Type=�Object� /> ... </InsertParameters></asp:SqlDataSource>
to:
<asp:SqlDataSource ...> <InsertParameters> <asp:Parameter Name=�UserId� /> ... </InsertParameters></asp:SqlDataSource>
This change worked for me; once the Type was removed the exception ceased and the updates/inserts worked as expected.Unfortunately this only partially worked for me as while it is fine for deletes it won't work for updates.If anyone can help shed any light on this I would greatly appreciate it.CheersMark

UPDATE #2: When it said "Do you want to install Microsoft SQL Server" I said "yes" and that caused it to work. I exited and re-ran and now the print runs w/o the "install SQL Server" (If the prompt had said "Do you want to install the print dialog" we wouldn't be having this discussion...)
UPDATE: After posting this i discovered that the same thing occurs when attempting to print the report direct from IE6: First a dialog pops up "Do you want to install this software?" Name: Microsoft SQL Server. When I click "Don't Install" I get the dialog "unable to load client print control." Since this happens direct from IE6 I suspect it's browser settings. I'll resume tomorrow and post a followup.
My WinForm C# app integrates Reporting Services by calling them from WebBrowser controls. The problem is attempts to print cause a dialog: "unable to load client print control."
I've read prior posts that say "enable Active-X in your browser" - I don't know how to do that from a WebBrowser control.
Any ideas how to support Reporting Services "Print" from within a WebBrowser control?

My development environment includes Visual Web Developer, SQL Server 2005 Express and SQL Server Management Studio Express. I have a .sql control string that creates a database. The control string is in my App_Data folder within my web site. When I use SQL Server Managment Studio Express to run the .sql control string and create the tables etc. it does it in my SQLEXPRESS folder and not in the web.
How do I run the .sql file so it will create the database in my App_Data folder within the web site?
Thanks,
Kyleq

SelectCommand="SELECT [icon], [file_name], [path] FROM [tblfile] WHERE ([file_name] = @file_name)">
<SelectParameters>
<asp:ControlParameter ControlID="txtSearch" DefaultValue="0" Name="file_name" PropertyName="Text"

Hi! I'm building a web application with ASP.NET, and using MS SQL 2000 for my database server.
How should I do to guarantee the integrity of the data in spite of the concurrent access? Meaning... how can I make sure that more than 1 user can update 1 table at the same time, while no error will occur? Do I need to add some codes at my aspx file? Or do I need to do something to my database? Or do I not have to worry about it?
Thank you.

If i use the TimeTracker app from the starter kit suite and I enter my SQL connection in the web.config file it works fine,
If i build a simple app with just a sqladapter, sqlconnection and dataset control then enter in the page_load procedure
sqlDataAdater1.fill(dataset11)
datagrid1.databind()
It keeps giving my errors see below: I created a connection with the sqlconnection control and used the same userid and password I used in the time tracker stater kit's web config file which works - I have no idea what is going on
*** is it better to create the sqlconnection control first then create the sqladapter or vise versa.

I'd like to check to see if a record exists in one table before inserting data into another.
