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
(OnSelectedIndexChanged). I can get the ItemIndex of the dropdownlist
using this code below:

((DataGridItem)((DropDownList)Sender).NamingContai ner).ItemIndex;

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).NamingContai ner.Parent.FindControl("LineItemGrid")).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)((DataGridItem)((DropDow nList)Sender).NamingContainer).NamingContainer).Na mingContainer).ItemIndex;
