I have an application, which is using RadGridView with additional DragDrop functionality and I have encoutered problems with applying all "Material xxx" themes for such a grid.
To find out the problem I have created new project from scratch, with new class:
public class CustomGrid : RadGridView
and then I have added 3 grids into WinForm.
First one is just normal RadGridView with "Material" grid applied, second is CustomGrid with "Material" theme applied and third one is CustomGrid with Office2010Black theme applied, as can be seen in attachment. First and third controls are working as intended, but there is a problem with the middle one.
As You see, the grid in the middle does not apply selected Material Theme - in such cases it is using "Fluent" theme all the time. The problem is connected with all 4 Material themes available in current version of WinControls. Is it possible to change it in easy way? I have changed like 80% of application and all grids which are not supporting DragDrop to this Material Theme, and it is blocking me from releasing this new version to customer.
