Can anybody help on how to use WindowsFormsHost in RadRibbonDropDownButton DropDownContent.
I copied the RadRibbonDropDownButton style, change the popup AllowsTransparency to false (as a known issue for WindowsFormsHost in popup) and set the new style for my RadRibbonDropDownButton, but it is still not show the winforms control.
Something still "block" it, but I did not find.
Please help! Thanks!
