Anybody know how to get a Templatefield column of text-boxes to feed data typed into them back into a sql database using the SqlDataSource already being used in the gridview the templatefield is in and a buttonfield using an update function? I was just wondering if anybody has any idea how to get this to work because I haven't been able to find any way of doing this.
Please let me know if any of you need any more information to help you solve this dilemma.
I am able to get the information to feed back into the SQL server if i enable edit and change the information in the textbox as well as another column's field in the same row, but it won't update if I only change the information in the textbox whether in edit mode or just clicking the update button.

So, changing the property of the SQLdatabase from CompareAllValues to OverwriteChanges fixed this issue. It is now allowing the changes to be written back to the sql database by just changing the textbox in the row/column that needed to be updated without having to change anything else.

I'm trying to update the 'question' field when I hit the 'update' button for a specific row. I am able to change the text when I hit the 'edit' button, but when I hit the 'update' button it reverts back to its original value. Nothing is changed in the database either.
Here is my markup:

EDIT:
After looking, in my EditItemTemplate, I bind the question to the textbox. Is it possible that after I click the update button that the original question is databound to the textbox again before it tries to update? If this is the case, how would I get around that?
After looking further into it, I realized I had forgotten the apparently very important "DataKeyNames" attribute in my GridView tag. I feel really dumb. Here is the new working code.

You need to handle this in OnRowEditing method.
protected void OnRowEditing(object sender, GridViewEditEventArgs e)
{
e.NewEditIndex -- will get you the Index of gridview, store this in some session or some variable .Helps you while you updating
//Assign value to the textbox.
Text1.text=GridView1.Rows[e.NewEditIndex].Cells[0].Text
Text2.text=GridView1.Rows[e.NewEditIndex].Cells[1].Text
}
And in 'Add' button event check for EditIndex is NULL
public void Button1_Click(object sender, System.EventArgs e)
{
If (EditIndex is null)
/// DO Insert
Else
// Do Update with EditIndex
}
This was working correctly, but now its inserting duplicate rows everytime I perform an insert from the page. Both rows are good with all data inserted correctly, but its putting the record in the database twice each time. How do I stop this?
VB.net code:
Protected Sub gvOnCallSchedule_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.CommandEventArgs) Handles gvOnCallSchedule.RowCommand

Try
dsOncallGroup.Insert()
Catch ex As Exception
MsgBox(Err.Description, MsgBoxStyle.Critical, "SQL Error")
End Try
End If
If e.CommandName = "Delete" Then
Try
dsOncallGroup.Delete()
Catch ex As Exception
MsgBox(Err.Description, MsgBoxStyle.Critical, "SQL Error")
End Try
'Response.Redirect("Default.aspx")
End If
End Sub

Put a break point on the call to dsOncallGroup.Insert() and see if it is called twice, if so then it is your code doing it and you can figure out where the second call is happening by examining the Call Stack window (Debug -> Windows -> Call Stack).
If there are not two calls in the code, then you need to investigate if a trigger has been added to your database that is somehow causing extra data to be inserted.
I have a DetailsView that looks just about perfect. The only thing is, there is one field that actually gets its information from another table. It is an ID field that is linked to another table in the database and I was hoping that there was some way to get that one field in the DetailsView to pull the information from the other table.
Is there a way to maybe add a + (plus sign) next to the PicklistID and then have it show the results of the other query? (SELECT TEXT FROM PICKLIST WHERE PicklistID = #PicklistID???)
UPDATE 1/11/12: The PICKLISTID in the table PICKLIST is not unique or a primary key so I cannot reference it from the SURVEY table. Is there a way to give these 2 columns a relationship so that I can just change my SELECT statement in my DetailsView to include the PICKLISTID?
UPDATE 1/23/12: I'm still stuck on this. I am not getting how to make this work at all. Help would be appreciated. I am still new....

You can do that, but maybe not in the way you want to.
The simplest way would be to use the DataBinding event on the DetailsView itself. Then use code to run the query.
Another way would be to create your own control as a subclass of BoundField and override the OnDataBindField method
The most performant way would be to join the data at the source in a DataView or another construct. Ideally the joining of data should be done as close to the actual source of the data (e.g. in a SQL query or view) to avoid unnecessary trips across the network to the database. For a single row it wouldn't be a big issue, but that is generally what you should do.
Working with .NET 2.0, I have a FormView with fields bound to an ObjectDataSource (ODS). Those fields start out with the correct values—that is, they come from the Person object when the ODS’s SelectMethod is called—but after making changes and calling the ODS’s UpdateMethod, I can’t get these new—or any—values from the fields from anywhere in the update’s call stack. My code looks like this:
<div id="personInfo"><asp:FormView ID="fvwPerson" runat="server" DataSourceID="srcPerson" DefaultMode="Edit">
<EditItemTemplate>
<table border="0" width="100%" style="font-weight:bold">
…
<td align="right">
First Name:
</td>
<td>
<asp:TextBox ID="txtFirstName" runat="server" Text='<%# Bind("FirstName")%>' />
Middle Name: <asp:TextBox ID="txtMiddleName" runat="server"
Text='<%# Bind("MiddleName")%>' />
Last Name:
<asp:TextBox ID="TextBox5" runat="server"
Text='<%# Bind("LastName")%>' />
…
</EditItemTemplate>
</asp:FormView>
</div>
…
<asp:ObjectDataSource ID="srcPerson" runat="server" SelectMethod="GetPersonInfo" UpdateMethod="SavePersonInfo"
TypeName="BLL.Person">
<SelectParameters>
<asp:SessionParameter Name="personID" SessionField="personid" DefaultValue="0" />
</SelectParameters>
<UpdateParameters>
<asp:Parameter Name="firstName" Type="String" Direction="Input" DefaultValue="Fail 1!" />
<asp:Parameter Name="middleName" Type="String" Direction="Input" DefaultValue="Fail 2!" />
<asp:Parameter Name="lastName" Type="String" Direction="Input" DefaultValue="Fail 3!" />
</UpdateParameters>
</asp:ObjectDataSource>
In SavePerson, the parameter values are “Fail 1!”, “Fail 2!”, and “Fail 3!”, respectively. I’ve also tried using FormParameters, with the same results:
<asp:FormParameter Name="firstName" FormField="txtFirstName" Type="String" Direction="Input" DefaultValue="Fail 1!" />
<asp:FormParameter Name="middleName" FormField="txtMiddleName" Type="String" Direction="Input" DefaultValue="Fail 2!" />
<asp:FormParameter Name="lastName" FormField="txtLastName" Type="String" Direction="Input" DefaultValue="Fail 3!" />
I also tried preceding the field names with "fvwPerson.". I also tried handling the Updating event for the ODS but e.InputParameters all began with "Fail". I really thought I was following all the right examples, what am I doing wrong? Please save me from having to call DirectCast(fvwPerson.FindControl("fieldName"), TextBox).Text 38 times! Thank you…
EDIT 7/6/10: I probably should have mentioned that I have only the item template for editing, not one for viewing (I didn't feel I should have to duplicate all those controls), and as the FormView tag indicates, edit is its default mode. Is that a potential source of my problem?
