Because the This example has a text box that accepts user input, which is a potential security threat. NET Web pages validate that user input does not include script or HTML elements. event to examine the values of a return value or output parameters, or to determine whether an exception was thrown after an Update operation has completed. What I have done to narrow down the problem: (1) Replace Object Data Source with an equivalent Access Data Source : same problem.(2) Check that sequence, parameter names and number of Bind("xxx") in Edit Item Template is identical to Object Data Source's parameter collection (3a) Create a new Test.aspx, using Access Data Source, update command works. Such concept is often called persistence ignorance.

I have written a Data access layer that the database object classes call to access the data. there any tools to tell me what events has been fired upon clicking a Form View's linkbutton? I have debugged that ODS's On Updating event is not invoked when I press the link button whose command name = "Update". NET's official class library between clicking the button and ODS's On Updating event, an exception must have been thrown, but it simply does not throw to the surface (believe me, I am already working under debug mode, every uncaptureded error must throw to surface).Such exception is probably aroused when ODS's do not match ODS Update Method's parameter.My current solution is a method in the class "Device" that just goes back via a "return" command and so the Row Updating from my code behind is doing the job... I think it would be useful for you: Hm thank You for Your answer, but it is not possible to use the Update-Event of the grid right?

operation is performed, the On Updating method is called to raise the Updating event.

The following code example demonstrates how to use a Drop Down List control, Text Box controls, and several Object Data Source controls to update data.
