RadCollapsiblePanel: Expand button scales incorrectly in high DPI

Hi team again,


The expand button becomes oval and shrunk in high DPI. It scales correctly in the default theme, but incorrectly in other themes - I tested Crystal/Material/Fluent and neither worked. Please see ss attached for your reference.


Thanks a lot.

Hello, Yusi,

Indeed, the header button shrinks in many of the themes when the application run on higher than 100% DPI scaling. The undesired behavior is reproducible even in the Demo application. 

I have logged it in our feedback portal by creating a public thread on your behalf. You can track its progress, subscribe for status changes and add your comments on the following link - feedback item.

I have also updated your Telerik points.

Currently, the possible solution that I can suggest is to specify minimum size for the button:

Me.RadCollapsiblePanel1.CollapsiblePanelElement.HeaderElement.HeaderButtonElement.MinSize = New Size(30, 30)
I hope this information helps. If you need any further assistance please don't hesitate to contact me
