Parameters
- row
- Row index.
- col
- Column index.
- clip
- Whether the range should be clipped to the visible area of the grid.
Return Value
A CellRange object that contains the given cell.
Cell merging is controlled by the AllowMerging property. The GetMergedRange(Int32,Int32,Boolean) method allows you to determine whether a cell is merged with adjacent cells.
You can override the GetMergedRange(Int32,Int32,Boolean) method to implement custom merging logic. If you do this, make sure the merging method is consistent and efficient, since it gets called frequently and affects the grid's appearance and behavior.
