.NET Forum / ASP.NET / General / December 2007frameset in visual studio 2005
Hi there, I'm working on creating a web page having two sections. The top one does not change (it loads the data from a database once) and the second section has two possible schemas (it's actually two different pages). The solution I have found is to create two horizontal frames and set the first page as the source for the first frame and then programmatically change the source for the second frame to display one of the other two possible pages. I have seen VS 2005 does not have a frameset control and I had to add it manually in the aspx file. My questions are: 1) Why VS2005 does not have support for the <frameset><frame> control? 2) Is it possible to accomplish this result with a different aproach with no frames? 3) Is the use of frameset an outdated practice? If yes why? 4) What's the difference between frame and iframe? Is it's use a good practice? Thank you very much, Ivar > 1) Why VS2005 does not have support for the <frameset><frame> control?

MasterPages create a similar sort of effect as framesets, although architecturally they are very different - MasterPages are UserControls, and the entire page gets rebuilt every time the content page changes... > 3) Is the use of frameset an outdated practice? Depends which particular "guru" you ask... :-) > If yes why? http://apptools.com/rants/framesevil.php http://www.456bereastreet.com/archive/200411/who_framed_the_web_frames_and_usability/ http://www.sitepoint.com/forums/showthread.php?t=257936&highlight=frames > 4) What's the difference between frame and iframe? Frames need to live within a frameset (OK, that's not 100% accurate) but iframes are inline frames which mean that they live within the main page and allow independent content. > Is its use a good practice? There's no real need for them any more, IMO, especially with the advent of AJAX which supports updating of page sections via callback without needing to postback the entire page...  SignatureMark Rae ASP.NET MVP http://www.markrae.net Thank you. I did not find an explanation like yours before, this is why I posted it here. Thanks again.

[quoted text clipped - 9 lines] > Depends who you talk to: > http://www.webdevout.net/articles/beware-of-xhtml You may be right. Can you use frames in a valid html strict DTD ? I just go by what I read and hear. If you say it ain't so - and you have that MVP title- then I must believe you. Why are there rumors that frames are being deprecated? here's a link you might like http://htmlhelp.com/reference/html40/html/doctype.html#strict and here's one from the w3c http://www.w3.org/TR/html401/index/elements.html have fun > Can you use frames in a valid html strict DTD ? HTML 4.01 has three DTDs: HTML 4.01 Strict DTD includes all elements and attributes that have not been deprecated or do not appear in frameset documents. HTML 4.01 Transitional DTD includes everything in the strict DTD plus deprecated elements and attributes. HTML 4.01 Frameset DTD includes everything in the transitional DTD plus elements and attributes for creating frames. If frames are avoided, there is no need to use this DTD. > Why are there rumors that frames are being deprecated?

SignatureMark Rae ASP.NET MVP http://www.markrae.net >> Can you use frames in a valid html strict DTD ? > [quoted text clipped - 20 lines] > > What am I supposed to learn from those...? ** That Strict DTD is the only DTD that does not allow deprecated tags. ** Strict DTD does not allow frames. therefore : yes, lets hear it - frames will be going away as the industry moves to strict DTD. The transitional DTD and the frameset DTD allow deprecated tags, but the strict DTD does not, right? The Strict DTD does not allow framesets, right? Deprecated tags should not be used because the support for those tags will eventually go away, right? Shouldn't one expect that when the deprecated tags go away, so will the DTDs that allow them? Since the frameset DTD is one of those DTDs that allow deprecated tags, then it will probably go away. The end > The transitional DTD and the frameset DTD allow deprecated tags, but the > strict DTD does not, right?

There are eleven tags which are deprecated in the strict DTD: APPLET, BASEFONT, CENTER, DIR, FONT, IFRAME, ISINDEX, MENU, S, STRIKE, and U. They will eventually be removed from the frameset DTD too. However, the frameset DTD itself will remain for the forseeable future, specifically to support frames - that's what it's for... > Shouldn't one expect that when the deprecated tags go away, so will the > DTDs that allow them? The transitional DTD will eventually disappear leaving only strict DTD and frameset DTD. > Since the frameset DTD is one of those DTDs that allow deprecated tags, > then it will probably go away. It will remain as long as the strict DTD - both will eventually be replaced by newer standards...
