While trying to build a quick POC using Telerik diagram control I came upon this issue.
When I try to bind "Associated Diagram" in the RadDiagramRibbonBar, I get an error when I click on the Drop down control.
---------------------------
Microsoft Visual Studio
---------------------------
Error using the dropdown: Unable to cast object of type 'System.Windows.Forms.UserControl' to type 'System.Windows.Forms.Form'.
---------------------------
OK
---------------------------
I understand that an Excel Document Action Pane is in effect a UserControl type but I was wondering if there was a work around to this scenario.


Hi
How can I left align the text in the virtualGrid (with only one column and AutoSizeColumnsMode set to Fill).

Hello again folks.
Can someone please show me how to edit the border and background colors of the DesktopAlert Context Menu that appears when the "Options" button is clicked?
Thank you!

Hello there,
I added a RadButton to my WInForm and although I can find TextPrimitive.TextOrientation property in the Designer, I cannot find it through the Telerik API so I can change it in runtime!
Telerik Designer and API are not consistent with each other?
Any idea on how I can resolve my problem?
Thank you,
Maria

I reported the issue below back in September 2017. It was scheduled for a fix in R1 2018 (here). However, it appears that the problem persists. Did it get missed or is there a setting/option that I'm missing. I think it is a rather major issue for anyone trying to put a DPI aware app together.
This is the problem:
In a DPI aware app, using the docking tool window auto-hide dramatically increases the size of any controls on the window. This can be demonstrated with a new application. Add a RadDock to the form, add a couple of tool windows and a document window, and add a few controls to either of the tool windows (label, button, treeview, property grid, etc.). Run the app as DPI aware at 150 scale. Hide a tool window. Open the tool window. When the tool window slides open all the font and control sizes have greatly increased.
