I'm using MSFlexGrid control and trying to show various tooltips depending on cell which is under the mouse pointer. Some cells are empty and shouldn't have tooltip.
And now - the problem. When mouse is moving from non-empty cell to an empty one, the old tooltip stays visible. If I try with setting the ToolTipText property to "" in the case of empty cell, an ugly little "box" (empty tooltip, I supose) apears in that moment.
Is there way of turning off tooltip text exept by setting its property to ""?
How to solve this?
