I already spend 2 days trying to solve this issue but no luck on how to solve this.I have a Grid View to display data from the database then it also have functionality to modify and delete.You need to include the Grid View Command Field column to add Edit, Update and Cancel Buttons in the Grid View. You need to include Template Field for every column you want to provide Editing because Template Field provides you both Item Template and Edit Item Template to create interface for two separate Grid View modes. You need to handle Grid View events such as Row Editing, Row Canceling Edit and Row Updating to provide desired editing functionality.Font-Names="Verdana" Font-Size="10" Data Key Names="Product ID" Auto Generate Columns="false" onrowcancelingedit="Grid View1_Row Canceling Edit" onrowediting="Grid View1_Row Editing" onrowupdating="Grid View1_Row Updating"In the above code, I set two properties Show Edit Button and Show Cancel Button of Command Field. w=800" src="https://taditdash.files.wordpress.com/2014/06/debugger-inside-gridview-rowupdating-event.png? w=800&h=359" alt="Debugger Inside Grid View Row Updating Event" width="800" height="359" class="size-full wp-image-328" srcset="https://taditdash.files.wordpress.com/2014/06/debugger-inside-gridview-rowupdating-event.png? w=230" src="https://taditdash.files.wordpress.com/2014/06/gridview-on-browser.png? w=800" alt="Grid View on Browser" class="size-full wp-image-335" srcset="https://taditdash.files.wordpress.com/2014/06/230w, https://taditdash.files.wordpress.com/2014/06/gridview-on-browser.png? w=416" src="https://taditdash.files.wordpress.com/2014/06/gridview-cell-showing-updated-value.png? w=800" alt="Grid View Cell Showing Updated Value" class="size-full wp-image-331" srcset="https://taditdash.files.wordpress.com/2014/06/416w, https://taditdash.files.wordpress.com/2014/06/gridview-cell-showing-updated-value.png?If we move our mouse on to the variables, which hold the cell values, we can see the old value instead of new updated value (Refer the debugging Screen Shot at the Top). When posting in this forum, please always provide as much detail as possible.
The Row Updating event is raised when a row's Update button is clicked, but before the Grid View control updates the row.
This is the current ASP code for my Grid View: The problem is I can't update a certain record after click the Update Button, please see the image below: When I'm in debug mode, it does not pass on On Row Updating event instead it passes to On Row Editing.
before that i want just using Find control and casting and then retrieving all lot code. If values are same they could notify user to change the value(give new cell value).

This enables you to provide an event-handling method that performs a custom routine, such as canceling the update operation, whenever this event occurs. On Row Updating(Grid View Update Event Args) method also allows derived classes to handle the event without attaching a delegate.
