Gridview onrowupdating not
You may notice that the last column of the Grid View is a Delete column that let user delete the record from database, so I have placed Delete link button inside the tag and have specified on Click property as Java Script confirm return value, so that when user clicks on it he/she sees a confirmation box whether he/she really wants to delete the record.You can notice that I have kept Required Field Validator too inside the Edit Item Template as I want the textbox to be validated for empty data.In the same way you can put any kind of Validation controls inside Edit Item Template to validate the form element while user will click Update link.Till now our Grid View is ready to be populated, now let’s write a method to populate the Grid View.
To populate the Grid View, I am calling Bind Data() method from Page_Load event after checking Is Post Back property of the page, so the Grid View will only be populated when there is no postback on the page (when the page loads for the first time).
When Update link of the Grid View will be clicked (in edit mode), On Row Updating event will fire that will call Update Record method.
