When I finally resort to set the Update Method's parameter manually, everything works!This is a strong evidence of such a possible exception.NET is smart enough to do it for me automatically !! Supplement information: Upon clicking Edit Item Template's update link button: Item Command event is triggered, then return and goes no further. This is my foresaid work around solution: programmatically fill in datasource's parameters, when apparently ASP. However, I am still appreciate if anyone can explain this problem.Why isn't Form View's Item Updating event fired, when obviously link button's command name = "Update"? protected void Form View1_Item Command(object sender, Form View Command Event Args e) protected void Object Data Source1_Updating(object sender, Object Data Source Method Event Args e) protected void Object Data Source1_Inserting(object sender, Object Data Source Method Event Args e) private void set ODSParameter(Object Data Source Method Event Args e) Thanks for your suggestion, but I don't think it is a common practice to invoke ODS' update event manually.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. The Update method is invoked directly by the data-bound control instead.The Drop Down List displays the name of a Northwind employee, while the Text Box controls are used to enter and update address information. One piece of additional information: certain bind fields in the formview's edit template are optionally set to invisible during the course of editing.
