Detailsview1 fired event itemupdating which
However, when I tested it I got the error "The Details View 'dv Grid' fired event Mode Changing which wasn't handled." This post stated "Either implement that event or remove the handler from the code-behind." This however made no sense to me. All these webforms controls require the data source to operate, and auto editing, auto deleting, auto sorting, etc. Am I creating the markup for a second third and fourth detailsview to display what is needed for edit, delete, and insert?

Then double clicking it opened textboxes for the item field contents and changed thelinkbuttons to read update and Cancel. Doubleclicking New after several attempts eventually changed the details view to field headers with empty textboxes with the linkbuttons Insert and Cancel. Double clicking brought me back to the original detailsview. Http Exception: The Form View 'dv Bulletins' fired event Item Updating which wasn't handled. There are many variations of online dating scams originating in Russia and Eastern Europe but they have in common a high emotional and financial cost to unsuspecting scam victims.This is my first experience using the details view. The fifth one sent me to Startv20/util/srcview.aspx? I was able to populate it from one datasource if the selection were made at the top level, or a different datasource if it were populated at the inner level.
