When dragging a column for reordering or grouping, I get the error below.
When I drag fast enough, I can get the reordering and grouping to succeed most of the time.
This error started occurring when I upgraded to the new version of controls - 2013.1.403.1050.
Also upgraded from Silverlight 4 to Silverlight 5.

Thanks

Hello Steve,

Could you test your solution with our latest internal binaries - version 2013.1.0507 and let me know about the result ?

Hi,

I overwrote the dll's in the C:\Program Files (x86)\Telerik\RadControls for Silverlight Q1 2013\Binaries\Silverlight folder with the ones in the latest internal binaries.
Then I reapplied the references in my silverlight projects.
I get compile errors related to the Telerik controls. Below is an example:

XAML
The name "RadDatePicker" does not exist in the namespace "http://schemas.telerik.com/2008/xaml/presentation"

CS
The type or namespace name 'RadDatePicker' could not be found

Thanks

Hi Steve,

Do you have reference to Telerik.Windows.Controls.dll ? If yes, can you try to clean and rebuild the solution? Also, please check if all the referred dlls have one and the same version.

Hi Yordanka,

Thanks for the quick reply.

Telerik.Windows.Controls.dll is referenced
The versions of the 11 Telerik references all point to the same version.
I have cleaned and rebuilt.
I have not touched the noxaml folder/files.

Hello  Steve,

We have tested it with the assemblies from the last Internal Build, but we were not able to get the error. Please note that the RadDatePicker needs the Telerik.Windows.Controls.Input.dll and it could be great if you can check this one also. In case you are still getting the error it could help if you can send us your project along with the assemblies you are using so we can get to the bottom of it.

Hi Georgi,

The dll's for the internal build were marked as blocked. I dicovered this by creating a test silverlight app and adding the Telerik references. The issue showed in the compile of the test app. Once the dll's were unblocked, the application compiles and runs.
But, the error of not being able to reorder or group remains.

Thanks,
Steve

I have reproduced this issue in a test app that I built from scratch.
Reordering and grouping works fine when the gridview is in the root layout grid,
and also when the gridview is in a radpane.
But when the radpane hosts another radpanegroup, and the gridview is in the nested radpane below,
the errors start occurring.

I can upload the entire solution with bin, or just the source.

Thanks,
Steve

Hello, I am wondering if this issue has a resolution to it. Should I send someone the sample project that reproduces the error?

Thanks,

Hello Steve,

Thank you for the details.

I was able to reproduce the problem and logged it as a bug. We will do our best to address it in one of the next internal builds.

I've updated your Telerik points accordingly.

Hi Steve,

We are sorry for the late replay.
While investigating the issue we have found you that it as a Dockiing issue and it is not as simple as it may seems. The issue is caused by the using of nested docking ( pane group hosted in a pane), which currently is not supported. Nevertheless we are researching nested docking and it would be great if you can give us more information of the scenarios in witch you are using it.
According to the fix for the issue, we have some internal fix and if it passes the necessary testing it would be available in one of our next internal builds.

Edited again!

The fix works! So far everything else seems to work. I will know for sure with further testing, but as of now, release 527 allows the application to once again properly reorder and group.

Thank you,
Steve
