TreeView Ajax

Hello, I want to use a TreeView with Ajax, i put a TreeView inside a UpdataPanel but no compatibilty, So how to do for using a TreeView in Ajax, thank's.

You can either buy a 3rd party control that uses ajax, hack around with the prerender event, write your own treeview control, or wait around for a future ajax release that may or may not support it.


what do u mean bye hack the prerender


I have heard of some people writing code in the prerender event to handle the maintenance of the tree since it is not supported in update panels (although during the CTPs, it appeared to work well...that is why I mentioned waiting as an option because I heard they may fix it with the next release). We do not do this because we never got it working 100% without errors, and we bought the telerik ASP.NET control suite, which includes a tree with ajax functionality.


Hello, Can I know when the next release of asp.net ajax will appear??


Hi kadben,

You can find the Asp.Net Ajax Future at this url: http://quickstarts.asp.net/Futures/ajax/default.aspx You can down it here: http://www.microsoft.com/downloads/details.aspx?FamilyID=4cb52ea3-9548-4064-8137-09b96af97617&DisplayLang=en

In additional, here is the document for "Changes between the ASP.NET AJAX ("Atlas") CTP and the RTM Releases".

http://ajax.asp.net/documentation/AspNet_AJAX_CTP_to_RTM_Whitepaper.aspx

Hope it helps.
