To get the row index of DataGrid when change(asp:radiobuttonlist) occur in row of the TemplateColumn

<asp:DataGrid ID="dgTier2" runat="server" AutoGenerateColumns="False" Width="578px" 
     Height="83px" OnItemDataBound="dgTier2_ItemDataBound">
    <asp:BoundColumn  DataField="TypeID" HeaderText="TypeID">
    </asp:BoundColumn>
    <asp:BoundColumn  DataField="Type" HeaderText="Category Type">
    </asp:BoundColumn>
     <asp:TemplateColumn HeaderText="Manual Tracking Option" >
      <ItemStyle VerticalAlign="Bottom" />
       <itemtemplate>
        <asp:radiobuttonlist id="rdbtnManual" runat="server" on RepeatDirection="Horizontal">
        <asp:listitem id="M"  runat="server" Text="Manual" Value="1" />
        <asp:listitem id="A"  runat="server" Text="NoManual" Value="0" />

My answer..

I have add the OnSelectedIndexChanged property in itemtemplate column.

<asp:TemplateColumn HeaderText="Manual Tracking Option">
    <ItemStyle VerticalAlign="Bottom" />
    <itemtemplate>
    <asp:radiobuttonlist id="rdbtnManual" runat="server" AutoPostBack="true" OnSelectedIndexChanged="ManTracChanged" RepeatDirection="Horizontal">
    <asp:listitem id="M"  runat="server" Text="Manual" Value="1" />
    <asp:listitem id="A"  runat="server" Text="No Manual" Value="0" />
    </asp:radiobuttonlist>
    </itemtemplate>
</asp:TemplateColumn>

in code behind

  'for storing list of RowIndex which change occur  
  Private objListManTrack As New List(Of Integer) 

  Protected Sub ManTracChanged(ByVal sender As Object, ByVal e As EventArgs)
       Dim RowIndex As Integer = Nothing
       Dim rblist As RadioButtonList
       rblist = CType(sender, RadioButtonList)
       Dim modifiedgriditem As DataGridItem = CType(rblist.Parent.Parent, DataGridItem)
       RowIndex = modifiedgriditem.ItemIndex

        If Session("objListManTrack") Is Nothing Then
            objListManTrack.Add(RowIndex)
            Session("objListManTrack") = objListManTrack
        Else
            objListManTrack = Session("objListManTrack")
            objListManTrack.Add(RowIndex)
            Session("objListManTrack") = objListManTrack

        End If

End Sub

in function i am making the list of index Of the Grid Rows which got changes.

finaly get the list of updated rows then we can reflect the changes to DB in one Button click event....
