On page 434, the Sender object isn't working for me. You have to write a small event handler for the GridView1_PageIndexChanged event. It is supposed to contain the following:

But when I typed "Sender." no intellisense came up. I changed it to GrideView1.PageIndex and GridView1.PageCount and it works.

I can see the usefulness of using the Sender object, and I want to know why it isn't working.

Now I do have my code in a code-behind file instead of in <script> tags, would that be the reason?

Well, the intellisense comes up, but it only lists 5 items like ToString, not the PageIndex or PageCount items. I rebuilt the page without the code-behind, putting the functions in the <script> tags and got the same result. Intellisense doesn't list the correct options. The functions do work, but I'm a little disappointed that the Intellisense doesn't work properly.

Am I doing something wrong?
