OnSelectedIndex Changed runs twice!

VB Programmer

Using ASP.NET 2.0...

My GridView is partially defined as such....

<asp:GridView ID="CartGrid" AutoGenerateCol umns="False"
DataKeyNames="I D" OnSelectedIndex Changed="Remove CartItem"
CellPadding="4" runat="Server"
ForeColor="Gray " GridLines="None " Width="90%"
BorderStyle="In set"
BorderWidth="1p x" Caption="Shoppi ng Cart" Font-Bold="False"
CaptionAlign="L eft">
<Columns>
<asp:ButtonFiel d
CommandName="se lect" Text="Remove" />
<asp:BoundFie ld
DataField="Name " HeaderText="Nam e">
<ControlStyle
Width="300px" />
<ItemStyle Width="300px"
/>

As you can see, when the user clicks "Remove" it runs the "RemoveCartItem "
function, defined as such...

Sub RemoveCartItem( ByVal s As Object, ByVal e As EventArgs) Handles
CartGrid.Select edIndexChanged
Dim ID As String = CartGrid.Select edDataKey.Value
Profile.MyShopp ingCart.RemoveI tem(ID)
BindShoppingCar t()
End Sub
Sub BindShoppingCar t()
If Not Profile.MyShopp ingCart Is Nothing Then
CartGrid.DataSo urce = Profile.MyShopp ingCart.CartIte ms
CartGrid.DataBi nd()
lblTotal.Text = Profile.MyShopp ingCart.Total.T oString("c")
BindShippingDdl ()
End If
End Sub

I put a breakpoint on RemoveCartItem and the code is running twice each
time. Any ideas why?

Thanks!

FYI: Even AFTER I comment out the BindShoppingCar t call it still calls
RemoveCartItem twice...

Any ideas?

Got it! I removed "Handles CartGrid.Select edIndexChanged" from
RemoveCartItem and it works. It was calling twice, once from the dg and
once from the SelectedIndexCh anged event I suppose.

OnSelectedIndexChanged event not firing on a DropDownList within a DataList

by: Paul L | last post by:

Hi, I have an issue with the OnSelectedIndexChanged event not firing for a DropDownList control which is in the ItemTemplate of a DataList. I have made an exact copy of the DropDownList control, and placed it outside of the DataList and it fires the event just fine. So it's definitely to do with it being in a template. I've managed to reproduce the issue on a small test app, the code and html is below:

For most users, this new feature is actually very convenient. If you want to control the update process,...
