Datagrid rowupdating

New Edit Index 'Bind data to the Grid View control. Bind Data() End Sub Private Sub Create Data Table() Dim cmd As New System. Dim dt = CType(Session("dt"), Data Table) 'Update the values. After it has been clicked the postback places that row in edit mode. At this point in time the above Edit Item Template is displayed with two Image Buttons within it.One has it's Command Name = "Update" and the other "Cancel".event is raised when a row's Update button is clicked, but before the Grid View control updates the row.This enables you to provide an event-handling method that performs a custom routine, such as canceling the update operation, whenever this event occurs.(Note, in the gridview the Enable View State="False" - if I set it to True I get the standard "Failed to load viewstate. error) One strange thing that I've noticed that makes me think it's a View State problem is that if I change the Command Name of the Update button to "Edit" that postback event does get captured in the Row Command event... 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).

After searching long and hard I found a great article that solved my issue.

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.

To cancel the update operation, set the collections, if necessary, before the values are passed to the data source.

Take a look at the page load if you are binding on post back then the values get updated before you are able to access them.
