    Having 2 "out of domain" pages in one aspx page with dynamic heights

    Hi Team,

    I have to adjust two pages which are provided by 2 diff. services based on some query string, as of now I am using iframes but could not set the height dynamically. Both the child pages can came up with any height.

    and iframes are useless in this case as I have to set some height or else it will take the defualt value for height property.

    I tried to set it thru java script and css but got the "access denied error" as java script could not do anything outside domian/application.

    Is there any other control which can be useful in such cases. If yes, how can we use it.

    Thanks,
    Manik

      I don't know why you're having a problem.
      I was able to set the height and width of an iframe with both CSS and JavaScript:

      Code:
      <iframe id="theiframe" src="http://bytes.com/topic/asp-net/answers/874341-having-2-out-domain-pages-one-aspx-page-dynamic-heights#post3512844" style="height:50px; width:50px;" ></iframe>

<script type="text/javascript">
   var theiframe = document.getElementById('theiframe');
   theiframe.style.width="300px";
   theiframe.style.height="500px";
</script>
      -Frinny

              you have to set height and width 100%
              try this

              Code:
              <html>
<body>
<iframe scrolling=auto id=rf src="http://bytes.com/topic/asp-net/answers/874341-having-2-out-domain-pages-one-aspx-page-dynamic-heights#post3512844" frameborder=0 allowtransparency=true style="width:100%;height:100%"></iframe>
</body>
</html>

                          child page should take as much space as much the content it has..lets say if the content is till 200px and rest of the page is blank..it should take up to 200px only and second child page should start from there..

                          right now by using above code - child page is taking 1000px and thn second child page is rendering..tht directly menas that there is a 800px white space between the two content

                              hmm... it's look like you are trying to merge multiple html files into one :)

                                  Have you considered using percentages instead of pixels for your heights?
                                  How is this dynamic? What is setting the heights?

                                          Oh wait I think I see your problem now...
                                          You want to resize the IFrame according to the content within it...
                                          You can't get the "size" of the content because it's in the IFrame...hmmm

                                          I wonder if you could use cookies?

                                                  I'm going to move your question to the JavaScript forum. I'm not entirely sure how you would solve this problem and I think they might know (I'm certainly not a JavaScript expert).

                                                  I think that using a combination of Cookies and the iframes' onload event will do the trick though.

                                                  When the content is loaded in the iframe it'll have to set a cookie that indicates it's physical size....the onload event is fired whenever content is loaded in the iframe, at that point your code should check for the cookie and resize the iframe accordingly.

                                                  The trick will be timing though.....

                                                          Well, you could convert the aspx pages into "content pages" and use a master page. See if you could load the 2 content pages into 2 different placeholders in the master page.
