Hello

I've a problem, see attached code.

If you open the second form and open the combobox and then click on the group (dropdown is not closed because of the dropdown closing event) and then close the form. The dropdown "hovers" without any form/control.

Kind Regards,

Christian

Problem on move the current row on the grid

Insert Document Window

Hi,

Is there anyone who could tell me a way to insert a document window?

I am using radDock.DocumentManager.DocumentInsertOrder = DockWindowInsertOrder.ToBack;

If I added 3 DocWindows, it will be placed as Doc1 - Doc2 - Doc3

I wanted to place Doc3 between the other two if Doc1 is the ActiveWindow.

I am looking to insert an item in radDock.DockWindows but it has no Insert property.

RadDock.AddDocument always place it last or first depending on InsertOrder.

Am I missing a Property to allow such case?

Drag-n-drop Pageview, GridView, etc causes Exception

I'm getting an exception when I drag and drop a PageView, GridView, and a few other controls to the Form.

system.nullreferenceexception: object reference not set to an instance of an object (see attached screen shot).

No one else on my team has reported getting this issue. My existing projects are fine and I can drag and drop these controls to them, but when I create a new project and try to add these controls, I get the exception noted.
