If I call the Bind Grid() at the start of Row Updating then the Drop Down List is available, but the selected Value is lost.

I have therefore added the relevant xml, and when creating the grid, create the column as a Template Field and the Edit Item as a Drop Down List with its own Sql Data Source.

So far so good, this all works, the grid is displayed, the Drop Down List appears, filled with the correct data, shows the correct initial item and lets the user select another. The when trying to get the value from the Drop Down List in the Row Updating event, I cant find it. I create a Recursive Find Control method that ran through every control on the page, and it cant find it.

In my custom grid View control I cannot raise the Row Updated event.

I have tried to add an event handler to the Row Updated event of my custom control but it is not called.
