Nested datagrid event firing - item index of parent grid

[Andy]

Hello,

I have a datagrid within another datagrid. The innder datagrid
contains a dropdownlist which fires an event as index change
(OnSelectedInde xChanged). I can get the ItemIndex of the dropdownlist
using this code below:

((DataGridItem) ((DropDownList) Sender).NamingC ontainer).ItemI ndex;

This returns the ItemIndex of the dropdownlist of the inner datagrid.
However, I need to know the ItemIndex of the outter datagrid (the
parent datagrid) where the event is firing. So I use the following
code, but it did not work.

((DataGridItem) ((DropDownList) Sender).NamingC ontainer.Parent .FindControl("L ineItemGrid")). ItemIndex;

What should I do to get the ItemIndex of the parent datagrid.

Thanks a lot.

Hi Andy,

The NamingContainer to the child DataGridItem is the child DataGrid; the
NamingContainer to the latter is the parent DataGridItem that you are trying
to access.

((DataGridItem) ((DataGrid)((Da taGridItem)((Dr opDownList)Send er).NamingConta iner).NamingCon tainer).NamingC ontainer).ItemI ndex;
