I find myself with the usecase that I want to have a way to conditionally apply things to a column. For example I want to have a CellContextMenu be accessible only on specific types of columns since the context menu would be dependent on some data.
The workaround I have had so far is thatt I use the Property parameter, to store a metadata about the column, however this is a missuse of your design as I see it.
Perhaps there is some value in having such a parameter in the RadzenDataGridColumn?
