How can i trap the SelectedIndexChanged event on a dropdown within a Datagrids EditItemTemplate colu

[Dave M]

I have a datagrid with two edititemtemplate columns that contain
dropdownlists, these are 1)lists manufacturers of cars, 2)lists car
models for a manufacturer.

i need to rebind the second dropdown with only the models for the new
manufacturer that has been selected from the first dropdown, this means
i have to trap the SelectedIndexChanged event of the first drop down
list

Q. How do i trap the selectedIndexchanged event of a dropdown in the
edititemtemplate of a datagrid?

u can create a eventhandler function and assign it onselectionchanged in the
aspx page

eg:-
<ItemTemplate>
<aspropDownList id="DropDownList1" runat="server" Width="128px"
OnSelectedIndexChanged="DropDownList2_SelectedIndexChanged"
AutoPostBack="True">
