Objectdatasource onupdating not firing

Rated 3.95/5 based on 669 customer reviews

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).

The Expanded Image and Collapsed Image properties set the URL of the images to use to expand and collapse.The Object Data Source control enables developers to associate data or business layer classes with the ASP. I covered some aspects of the Object Data Source control in "Cache In Using the Object Data Source Control" specifically, the object instantiation and data caching.Methods of such classes can be designated as methods for data-bound controls to execute common operations, such as select, delete, update, and insert.It is simply a tool; a powerful tool indeed but not necessarily ideal for every situation.The Object Data Source control is particularly suited for declarative programming and, in general, all those scenarios where your information fits well in the control s programming interface.
