I am working on a piece of code written by some other person that uses Telerik. An issue I am trying to resolve right now involves GUI formatting.
In this picture
, you can see that the "Country" column has been highlighted and is active (i.e. has Distinct Filter). But in this case, that little wine-glass-like icon on the left is grey instead of orange. Do you know how I can make that icon change colour when the column is active?
The classes that are involved are RadGridView, a class that overrides IFilteringControl, and a set of GridViewColumns.
