Using VS2019 and 2022.1.228.40 of Telerik. How do I change both the Hover color and Selected color of the expand button from yellow/dark yellow to colors of my choice?
I found this post that looks like what I want. But when I try the code in the ViewCellFormatting event, I get an error that SignStyle is not a member of GridGroupExpanderCellElement.
Thanks for your help.
