Thank you for the clarification. I am using the caption element's Padding property to change the height of the group's caption. I have tested the PanelBar
layout system intensively, and I don't think there will be problem when you adjust the height.
Q:How to set it?
A:Use the code below:
int height = 15;
group.GetCaptionElement().Padding = new Padding(0, height, 0, height );
I hope this helps. Please contact me if you have any additional questions.
All the best,
the Telerik team
