I am binding to a custom datasource in the code behind.It gets into the "On Row Updating" event just fine, but there are no New Values or Old Values. Regarding on the Grid View control's Row Updating event problem, it is the expected behavior because when we do not associate Grid View(or other ASP.New Values collection is empty in the Row Updating event Handler. New Values contains the collection of values updated in the Grid View control. The database table used here has just two fields (sid and sname) My code is as follows: Web Page: --------------------------------------------------------------------------------------------------- im having the same problem i think: in my case i have set binding for template fields; ive a grid with 2 types of field: - bound filed editable (no the tamplate) - bound readonly field (template field) ive set Eval for the template and it is readonly, i placed also Bind to make a test but still count is zero; also had a try changing the datasource, and sure i have set the key field for the grid. OK, so I solved my problem, but not straight forward. I am having a similar problem, but I don't have any Edit Item Template items in my grid. I just changed my code to use an Object Data Source. I just selected the Auto Generated Edit Button and Auto Generated Delete Button properties to True in the properties tab for the grid. Took 15 minutes to change it, my code is half if not less than it was before, and all I worked hard for now just works straight forward. This enables you to provide an event-handling method that performs a custom routine, such as canceling the update operation, whenever this event occurs.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.
