user control in a datagrid does not work with a delegate and event

Hi, I have a user control that raises an event which works perfectly
outside a datagrid. But trying to do this within a datagrid causes
some problems.

Here is what I have. For the given datagrid, in the event handler for
ItemDataBound, I have

enable_disable userContentEnableDisable =
(enable_disable)e.Item.FindControl("userContentEna bleDisable");

//tying handler to the event
userContentEnableDisable.OnSelectionModeChange += new
enable_disable.SelectionModeChangeHandler(userCont entEnableDisable_OnSelectionModeChange);

Then when I perform an action that raises an event, I get the
System.NullReferenceException.

Again, this user control's delegate and event work without a problem
outside the datagrid. Any ideas?
