    The RowDeleted and RowDeleting event handlers are probably not getting executed because it does not appear as though anything is calling the delete command. You’re not generating a delete button and your custom button is not calling the delete command. See the example in the RowDeleting event documentation for how to implement the use of the event. Notice that the example sets the “AutoGenerateDeleteButton” property to true. When they user clicks that button, the RowDeleting and then RowDeleted events will fire.

    I’m not sure why your custom button’s handler is not getting executed. Can you confirm that your page is indeed posting back? Are you able to debug through the code to see what steps it is taking during the postback? As Muhammad requested, will you please include your page load code as well as any other relevant code?
