We have a class CascadingNode inherited from Node class and overridden the PaintCellValue(). Added the CascadingNode as a column to fly grid.
When we hover the mouse on the column (CascadingNode) of the fly grid, the PaintCellValue() method is getting triggered. We would like to know what event (the exact name) initiates the execution of the code so we could prevent calling PaintCellValue() method.
