Rowupdating is not fired in gridview - featherweight sewing machine dating

Do not use this parameter to identify the current row. The Row Updated event occurs after the Validate Row event, which is fired before the modified row is saved to the data source.

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.I am using a SQLData Source to populate my gridview in ASP. When I hit Edit, the textboxes appear and I am able to edit my values. I am using a SQLData Source to populate my gridview in ASP. When I hit Edit, the textboxes appear and I am able to edit my values. In the Row Editing function, the edit textboxes appear and I can get the "old" values Then the page renders, I edit the textboxes and hit Update.When I hit Update, the changes are not saved, and there is no error message. When I hit Update, the changes are not saved, and there is no error message. Then the page posts back, the text boxes go back to being labels and the new values are lost, and the Row Updating code never fires. Yes, I did put the breakpoint at the Row Updating line (and not in the function).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.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.We’ll start with binding data to the Grid View, then build up functionality from there.First, we’ll implement a method to databind the Grid View, which will be called whenever databinding needs to be performed.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.NET 2.0 most of the examples and tutorials deal with setting the Data Source ID, which buys you a lot of automation that you may not even appreciate unless you’ve done this the old fashioned way.
