(datagrid) Retrieve the selected value (template dropdown control)

I have a template column with a dropdown control (in a datagrid).

I have AutoPostBack set to TRUE because I need to update a file when a selection has changed.

My question:

How to retrieve the selected value when posted back in the code behind? not knowing witch DDL was changed.

Here is the template code if it can help.
Thanks,



<asp:TemplateColumn>
<ItemTemplate>
<asp:DropDownList AutoPostBack=True id=DropDownList1 runat="server" SelectedIndex='<%# GetSelIndex(Container.DataItem("id")) %>' DataSource="<%#
GetUserType() %>" DataTextField="value" DataValueField="id">
</asp:DropDownList>
</ItemTemplate>
</asp:TemplateColumn>

You need to make an event handler for the drop down list.

EG:

Code:

---

    Public Sub Task_Changed(ByVal sender As Object, ByVal e As EventArgs) Handles cboGroup.SelectedIndexChanged
Response.write sender.Items(sender.SelectedIndex).Value
    End Sub

---

Make the HANDLES handle one of your drop down lists, but after that, you can send the SelectedIndexChanged event of ANY drop down to that same function.
