Thank you for writing.
Yes, we fixed the issue with the RadTitleBar when used in MDI scenarios. RadTitleBar uses the FindForm
method in order to find the top level window, which needs resizing or minimizing. We made this in order to enable placing RadTitleBar inside panels and keeping the possibility to resize the main form. In your case you are using a Form
with the TopLevel
property set to false,
which is a new scenario for us. We found a solution and it will be available in our upcoming release next week. We are sorry for not being able to help you right away.
Don't hesitate to contact us if you have other questions.
All the best,
the Telerik team
