Hello,
From your description, I understand that the background color of the Telerik PanelBar is only applied after the component is collapsed and expanded at least once, and you would like it to appear correctly on initial load.
At this stage, I would like to clarify a few details to better understand your exact requirement:
Are you referring to the PanelBar item headers (the clickable section), or
The content area that becomes visible when an item is expanded?
Additionally, it would be very helpful if you could share:
A short description or screenshot of the expected result
A minimal, isolated example (e.g., a REPL) that demonstrates your current setup
This will allow me to better understand the scenario and try to reproduce the behavior on my end, so I can provide a more precise solution.
