using frames is agaist current desigh standards.

if you really must than create a html page and have each frame's source set to the proper aspx page.

why are you trying to do this though?
maybe web parts can help you?

Definately consider web parts for your project as you can have multiple containers within one page. Start with a container using a div tag. Then create 4 more containers within that div tag. Then you will need to drag and drop a WebPartZone container into each frame. That should get you started. Let me know if you need a sample application.

Are you sure you don't want 3 user controls (ASCX) on the same page, instead of 3 ASPX pages? That's what user controls are for -- you create them and put them on any pages that can use them, sort of like frames but much better because they can all access the master page server side, and the parent page can access any public members of the controls, all using server-side code.

Even if those ASCX pages need to sometimes be on their own page, you can just create container ASPX pages for those controls.

Sorry I didn t specify the requirements correctly. Here is what I need:
i ll have a check box list. Each checkbox will be associated to a url address like: the checkbox1 is associated to http://url1 checkbox2 is associated to http://url2 ...and so on. According to the checkboxes the user will check off, i will load a page containing multiple frames. Each frame will include the page related to its URL defined in the checkbox list. I load a page including only the URLs of the checkboxes that the user chose.
Thanks a lot.

You might want to look into using HTML's IFRAME tag, if you haven't used that before. Basically let's you create in-line frames.

But as mladen said earlier, I would avoid frames in general if you can ... maybe step back and give us a more concrete example of what you are trying to do.

load all the selected pages (according to the selected checkboxes) in a brain new multiframwe page.
For example: I will display a page with 3 frames: first frame contains google home page, second frame contains ebay and third page contains yahoo home page. All this because let s say the user checked off yahho, ebay and google in the checkbox list.
Thanks

then put 3 frames in your page and then set each frames src with javacsript in the onclick event of the checkbox.

yes, but if the user checks off 4 checkboxes, then i will have to load a frameset with four frames according to the checkboxes. so the framset or number of iframes has to be set dynamically according to what the user chooses.
Thanks

If you used web parts you could accomplish this very easily as their is a Web Page Web Part property for a control. They can all be added dynamically as well. Let me make a book recommendation:

Darren Neimke's "ASP.net 2.0 Web Parts in Action"

Then use a simple REPEATER control and generate as many IFRAMES as you need. It's the same as generating DIV's or table rows or anything other HTML element on the page based on a datasource, only your template contains IFRAME tags.

I put 6 iframes in aspx page. In my Checkboxlist server control Whenever the user checks off a checkbox, In code behind I build a string including the list of all the selected URLs with the format: 'page1','page2',...., Then I pass that string to a javascript function that accepts 6 arguments: arg1, arg2...,arg6 (some arguments will just be empty when i call the function)

In the javascript function, I have this to set the URL for the iframe:

if (arg1!=null) document.getElementById("myframe1").src=arg1;
if (arg1!=null) document.getElementById("myframe1").src=arg1;
....etc

The result:
Here the result I got: If the user selects 2 checkboxes, I get 6 iframes with the first 2 set to the right URLs that the user selected and the last 4 iframes just empty.
I guess we are advancing (thanks for the iframe idea)
Now: if the user selects only 2 checkboxes, How can I get rid of the last 4 empty iframes on the page when the user didn t select them and display only 2 iframes.
The same thing if the user selects only 4 checkboxes. I don t want to have 6 iframes with the 4 first set to the selected URLs and the last 2 mainly empty. I want only 4 iframes displayed on the resulting page.

I guess this a javascript function since, remember I implemented the logic of setting iframes' URLs in javascript code.
Thanks a lot guys.

It's fairly trivial JavaScript to create as many iframe elements as you need and set their URLs, I'd recommend using DOM methods to create them:

http://msdn.microsoft.com/workshop/author/dhtml/reference/methods/appendchild.asp?frame=true

I can't say I think this is a good layout though. Very easy to get cluttered and chopped off, and don't be surprised if a number of JS-heavy pages don't work properly when they're framed.

I think you would be much better off to do this server-side, as opposed to client-side. Much, much easier and it will work with more browsers.

Also -- do not forget that cross-domain frames are often blocked by security settings on browsers these days ....

i must stress again to not use frames.
if you must, use divs with IFRAME in each one.

Ok, how do I do that differently to avoid trouble in future and for the code to be cross browser compatible or on the server side?
P.S: Spirit, I am using iframe and not frame
P.S j.Smith: If I use repeater for server side, what d be the datasource in my case?
Thanks for having walked me through this.

I did this on server side but it was slow (at least it worked on both firefox and IE which didn t when I used the client side version):
HtmlGenericControl IfURL = new HtmlGenericControl("iframe");
IfURL.ID = "myNewIframeIdd" + i;
IfURL.Attributes.Add("src", this.myChkBoxList.Items[i].Value);
HtmlTableRow tblRw=new HtmlTableRow();
HtmlTableCell tblCell=new HtmlTableCell();
tblCell.Controls.Add(IfURL);
tblRw.Cells.Add(tblCell);
MyTable.Rows.Add(tblRw);

Thanks.

DON'T USE HTML TABLES. Use DIVs (like everyone has been suggesting)
