Grid on DocumentPane not filled

[jpl]

Hello,

I have an MDI App using a DockingManager. The DockingManager is in the main Form. Rather than using AutoDetectChildForms and create DocumentPanes automatically by MDIChild Forms additions to the main Form, I prefer using custom DocumentPanes that I add programmatically to the DockingManager (because the AutoDetectChildForms feature clears the main Form's MDIChildren collection, and its a pity).

It works well... But !... any RadGridView designed on a custom DocumentPane doesn't fill with datas and doesn't display anything. (Even with this simple sample, 
List<string> myList = new List<string>();
myList.Add("One");
myList.Add("Two");
myList.Add("Three");
radGridView1.DataSource = myList;
)

Of course, I checked that the program does execute the lines above, the DataSource is well defined but the grid doesn't display anything. If I put the grid on a simple form, it works, of course.

What's going wrong with that ?!

Hello _,

We tried to reproduce this problem, but to no avail. Please send us a simple project that reproduce it so that we can test it locally. You can do so by opening a support ticket from your Client.net account.
 
Thank you in advance.

Here is a simple project reproducing the behaviour. Run it and choose a name of new tab to display/hide. On each tab you'll see a RadGridView empty while a DataGridView is filled in the same context.

Hi _,

The problem is related to BindingContext of RadGridView. Currently you can bind or set the DataSource property of RadGridView after the host DocumentPane window is docked. The issue is already solved and the fix will be available for upcoming major Q3 release planed for next month.

Sorry for the inconvenience. Your Telerik points have been updated.


Kind regards,
