DataGrid and a DropDownList

[mendhak]

I've got a template column in a datagrid which consists of a dropdownlist. I am handling the selectedindexchanged event of the dropdownlist, no problem. But what I want to do, is this:

If the selected index of the dropdownlist in row #7 changes, I'd like for a textbox in that same row to be enabled.

This was easy with the DataGrid's ItemDataBound event. All I had to do was:

DropDownList ddl=(DropDownList)e.Item.FindControl("cmbLeaveType");
string strLeaveType = ddl.SelectedValue.ToString();
TextBox txtTDT = (TextBox)e.Item.FindControl("txtToDateTime");

switch(strLeaveType)
					{
						case "LeaveWithoutApplication":
							txtFDT.Enabled = false;
							break;
// and so on

Thing is, I don't know how to access the "correct" textbox or control.

Any guidance?
