For those who do not know on how to generate Events in Grid View you can follow these steps below: I have a project that I coppied the above code into.
The Grid View does know the events that should be used to implement them, so the exceptions shown above are thrown when you try to perform one of these operations, but you have implemented the appropriate event handler.
The example shown here is for a Grid View, but the same types of event handlers must be implemented in roughly the same way for other data controls including the Form View, Details View, and List View. This is the final Grid View markup, so you can see the event handlers we’re going to implement.
Here's some code that needs to retrieve a Pk of one of the bound items and then perform some work on the data (in this case the business object): This seems like a lot of code to have to write just to retrieve data context.
The code first has to retrieve the Grid View Row, which is done by retrieving the Command Argument which in this case a row index of the rendered grid view items.

NET forums is how to deal with exceptions like The Grid View 'Grid View1' fired event Row Editing which wasn't handled.The Grid View 'Grid View1' fired event Page Index Changing which wasn't handled.Now let’s create a method for executing the Update or Insert.
