Drag&Drop problem with RadGrid in WebPart

[Oleg]

Hi, I develop WebPart included RadGrid 2008 Q2. I want to use Drag&Drop in this grid and set next options:

grid.ShowGroupPanel =

true;

 

grid.ClientSettings.AllowDragToGroup =

true;

 

I build and deploy WebPart  on test machine (VPC for SharePoint developer from Microsoft). It works fine. After I deploy WebPart on my work server (2003 Server SP2 + IE7). Add this WebPart on page. I see that Drag&Drop doesn't work. Mouse cursor doesn't look like as cross and I can't move a column header to group panel. What's a problem in? Thank you.

Hi Oleg,

I'm afraid that I'm not sure what may be the cause for such behavior from the given details. It will be highly appreciated if you can send us (attached to a formal ticket) a sample project in which this behavior can be reproduce or at least some code snippets and implementation details.

All the best,

Hello Oleg,

Unfortunately I'm unable to reproduce the described behavior locally. Are there any javascript errors on the page? Can you please check if the MOSS is configure correctly and has MS AJAX extensions installed?
