Hi, I have a column inheriting HierarchyColumn. It implements ISupportsCustomDropDown.
The only way to get any button to appear is to set EditorStyle to Dropdown.
However, I need to put my own image in the button.
I need a way to be able to have a button in the cell with my own custom image, if the column inherits HierarchyColumn, or any other column type for that matter.
Ideally this would be built in at the Column level, so any column could do this.
