For some reason, the Event Receiver doesn't seem to fire at all.The List Instance made from this list definition is a Hidden List (Not sure if this can be issue) Following is file for Event Receiver: What have I confirmed/tried? Confirmed that Custom List Definition List Template is "10101" .
This enables you to provide an event-handling method that performs a custom routine, such as canceling the update operation, whenever this event occurs.
A Grid View Update Event Args object is passed to the event-handling method, which enables you to determine the index of the current row and to indicate that the update operation should be canceled.
The Row Editing event loads the page and the page loads the Usercontrol again now the gridview is in edit Mode but the Grid View Row Updating event is not fired when the update button is clicked.
I already spend 2 days trying to solve this issue but no luck on how to solve this.
In this method, we have to get changed values of Text Box and Drop Down list and also we need the primary key value for the record that is being edited.
