>Hi keith thank . but i dont want to use frameset? do have an idea. one question can i use aspx for my frameset?

The frameset page itself can only be an HTML page. It has no content except the layout of the frames and the url of the page to display in each frame. Each frame can be linked to an aspx page.

The only other way to show multiple web pages on one aspx page is to create a WebRequest for each page that you want to display, strip out the header tags from the HTML, and add the remaining HTML to the Response stream of the "master page". You can add it to the cell of a table to control exactly where it displays. If you do this you will lose the ability to interact with server-side controls in the individual pages and the possibility of id conflicts in controls.
