RadControls for Asp.Net Q2 2007 issues of upgrading .NET from 2.0 to 4.0

[George Leung]

Hi, we upgraded our web site from .NET 2.0 to 4.0, then some controls of RadControls for Asp.Net Q2 2007 can't work properly.

Test Enviroment :

 

IE Version : IE8

IIS Version : 5.0

RadControls Version : RadControls for Asp.Net Q2 2007(ASP.Net 2.X)

 

Issue one :

If a page used controls in assembly named RadAjax.Net2, there will be some Javascript errors caused when loading these pages. Please see picture "err1.jpg";

 

If I remove these ajax controls from this page , there will be no Javascript error.

 

Issue two:

I can’t select a Item from RadComBox. And RadComBox will always only display the last item if I click the left mouse button. Please see picture "err1.2pg";

My question is :
Can "RadControls for Asp.Net Q2 2007" work on .NET 4.0? If yes, what I should do to fix above two issues? If not, what I shall do if I have to use .NET 4.0?
I tried Telerik.Web.UI_2012_1_411_Dev.msi on .NET 4.0. There are big differences between RadControls for Asp.Net Q2 2007 in coding. If I use  

Telerik.Web.UI_2012_1_411_Dev.msi , I have to change huge amount of code. I can't afford it.

Would you give me some solutions to solve this problem? thanks in advance.

George,

I am sorry to report that Telerik no longer offers full support for the use of the 5+ year old RadControls for ASP.NET 2.0, as noted on their .NET Support page. These products are in "Extended Support" phase:

"When a product enters the Extended Support phase, it will no longer receive active support. Support for these products will be available on a pay by incident basis and will be available for at least 2 years after a product suite leaves the Limited Support phase."

You will need to upgrade your application to the latest release of the RadControls for ASP.NET AJAX, as they're built against .NET 4.0 and optimized for this environment. By upgrading, you'll be able to take advantage of their comprehensive support during your redesign phase. And, your RadControl applications will take advantage of over 5+ years of bug fixes and product enhancements. So, you're better off to spend the time recoding as opposed to desperately trying to patch non-supported applications.

Hope this helps!
