Handle Update(Grid View Row row, Int32 row Index, Boolean causes Validation) 1226 System.
Handle Event(Event Args e, Boolean causes Validation, String validation Group) 716 System.
I want to control the "Row not found or changed" exception alerting the user that the record he's trying to update has been modified by someone else. https://msdn.microsoft.com/fr-fr/library/ui.webcontrols.linqdatasourcestatuseventargs.exceptionhandled(v=vs.110)Here you're just doing something in case of exception, but you don't actually handle it, you don't tell the stack that you've handled this case, all is well, no need to worry about it.
At the 'On Updated' method of the Linq Data Source, I can handle the exception by doing this: The problem is that a Java Script exception is raised and the alert does not appear, as you can see in my Firebug console: can I avoid that Java Script error and show my 'alert'? By the way, I would not check the HResult code of the exception (which seems flaky), but I would check the type of the exception.
