How to open an aspx page in a div tag that comes a modal dialog?

[soft_coder]

Hi! I am working with jquery and I need to open an aspx page in a div tag that comes as a modal dialog.

I am successful in doing the following:

$("#addaccount").load('test.html');
$("#addaccount").load('test.php');
$("#addaccount").load('test.jsp');

But when I do this:

$("#addaccount").load('test.aspx');

Something goes wrong and I am unable to do so.
Can someone help me!
