I have data bound DataGridView in a desktop app with columns that have their ToolTipText property set, yet no tool tip is displayed when I hover over grid view (cells or cell headers).

The ShowCellToolTips property of the grid view is true, and I have verified using break points that it is not changed programmatically before I mouse over.

I have tried creating a CellToolTipTextNeeded event handler to see what the tool tip text was, but the event handler is never called.

Is there anything I have missed?

Thanks, Rob

Edit: We’re using framework 2.0.

  1. We ended up using a ToolTip widget and the CellMouseEnter, CellMouseLeave events to show it appropriately. Not optimal, but it works around the odd behaviour we were experiencing.
