I've converted a buttonfield to a TemplateField with a button in it

Previously, in the Rowcommand, to identify the row when the ButtonField was
clicked, I had this code:

Dim index As Integer = Convert.ToInt32(e.CommandArgument)
Dim row As GridViewRow = MyGrid.Rows(index)

However, with the new TemplateField (with a button in the TemplateField), in
the RowCommand, it does not understand 'e.CommandArgument'

I get the error that the "input string was not in the correct format"

What am i missing here?
 
Hi Elmo,

ButtonField automatically puts the index to CommandArgument property of the
button. Now, because you changed it to TemplateField you are responsible for
binding the value manually yourself:

<asp:GridView runat="server" ID="MyGrid" AutoGenerateColumns="false">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:Button runat="server" ID="btn"
CommandName="MyCustomCommand"
CommandArgument='<%# Container.DataItemIndex
%>' Text="Click Me" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>

And the vb.net code behind:

Protected Sub MyGrid_RowCommand(ByVal sender As Object, _
ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) _
Handles MyGrid.RowCommand

If e.CommandName = "MyCustomCommand" Then
Dim index As Integer = Convert.ToInt32(e.CommandArgument)
Dim row As GridViewRow = MyGrid.Rows(index)
End If

End Sub

Hope it helps
