Hi, I'm trying to convert from RadControls for .NET to RadControls for Ajax .NET Q3 2010.

For all other components its been easy but for the RadWindow I can't get it to display the actual file.

I'm calling the window from a button click in the codebehind, and it displays the modal background effect but no actual file. 

I've tried paring it right back to basics, taking out a lot of the previously set properties, as well as setting the NavigateURL both in the properties and in the codebehind, and have tried a full URL, eg http://www.google.com to rule out any potential pathing issues but nothing seems to work.

Any ideas?

Thanks

Cheryl

Further to this, if I try to view the page in IE9 I get the modal background showing with no window regardless of whether compatibility is on or off.
If I try with FF I get the background, plus a window but the window is empty.

Hope that helps....

Hi Cheryl,

Actually, the IE9 browser was officially released and thus - officially supported by us - after the Q3 2010 release of RadControls. The problem you experience is due to a js error which is thrown while the lazy UI creation of RadWindow is in progress - that is why you do not see it displayed.


To resolve the problem you should upgrade to a version of RadControls which supports IE9 - the earliest one is Q1 2011 as stated in our release notes below:

Thanks for the reply.  The drawback with upgrading to a later release is that from the Q1 2001 release (which should solve my problem), is that I'd also be forced to move from .NET 2 which is not ideal for this particular project at the present time.

It is unfortunate that the IE9 support coincided with the dropping of the .NET2.0 support

Hello Cheryl,

Generally, .NET  is considered to be backwards compatible, so upgrading to 3.5 or 4.0 shouldn't be too complex, yet If it is not an option for the time being you can stick with the RadControls version that supports .NET 2.0 (the last one is Q3 2011 SP2) and use a function override to have the RadWindow work under IE9. More details about this are available in this forum thread.

Nevertheless, I would advise that you upgrade to the latest version (which is currently Q1 2012) as soon as possible, because 1) you would no longer need this override, 2) we no longer support .NET v2.0 and 3) in the last year we have added several new controls and extended the functionality of the old ones significantly.


All the best,
Marin
