So when we use these special key words as the Command Name for the buttons in the Grid View, they automatically invoke the built in functionality of the Grid View when we click on the button.As our code does not handle those events hence they throw an exception.When you click on edit button of the Grid View a Javascript error occurs : “Microsoft JScript runtime error: Sys. Page Request Manager Server Error Exception: The Grid View ‘gd Test’ fired event Row Editing which wasn’t handled.” At first look you may think that you have not handled some events fired by the Grid View. The mystery behind this error is the property “Command Name”.The simplest solutions for this error is : Just change the “Command Name” property of the “Edit” button from “Edit” to “Edit Row”(or something else which is relevent to you but make sure it is not “Edit”). After scratching my head for sometime I found that the words like “Edit” are reserved to invoke some built in functionality of the Grid View.However wen I click on Update nothin happens, currently it isn't connected to the database I just want it to change the text of a button so I know the update works.All was workin fine b4 I added the Update Panel and Content Template.Instead, it throw an exception Object reference not set to an instance. Protected Sub Grid View1_Row Updating(By Val sender As Object, By Val e As System. Open() cmd = New My Sql Command("update login set username='" & txt Name1.

We can achieve the same functionality using Datakeys.
