parent.document .getElementById ("file1iFrame") .height
self.parent.par ent.document.ge tElementById('f ile1iFrame')

What's the difference client-side between a master page and a non-master page?

Hi, I have a page with a series of child pages loaded into an iframe. When I move from page to page, I store an object containing the child's control data in a variable on the main page, then use that data to populate the controls when the child page is opened again.

I'm building a page in vb.net with several user controls on it. I'm using user controls instead of a frames page since I've seen this recommended many times in this user group. I want just one of the user controls to do a postback but not the rest of the page. Is this possible? it seems like it should be. If it is, please explain how I can do it. Thanks. -- moondaddy@nospam.com

I have an old existing website with a Header/ Left Hand Menu and a iframe as the main body content, adjacent to the menu. So for every click on the menu item, I used to load a aspx page on the iframe and hence i am not loading the entire menu and header for each request. When I try and port the above model to Master Page 1) The menu ( I thot of having the Menu Web control), Header would be moved to the master page.

Hi, I want to use 2 master pages, one for the main part of the site, the other for the admin pages. They are quite similar, with many shared elements. Ideally I would like to have a parent master page, which both of these child master pages are based on, and in turn the final pages are based on one of these child master pages.
