asp.net gridview AjaxControlToolkit

Question

Can I use AjaxControlToolkit to check whether ASP.NET GridView is Empty or Not?

Answer 1

An empty GridView control still renders its EmptyDataTemplate (or its EmptyDataText), so you can't just check if its associated <table> element is empty.

You might want to specify a custom EmptyDataTemplate that renders an element with a well-known id, then use $get() on the client-side to check if that element exists.

You can also create an extender on the GridView that passes its Rows.Count property to the client side using an ExtenderControlProperty.
