Gets or sets a value indicating whether or not ToolTips will show when the mouse pointer pauses on a cell.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
When the value of this property is true and the mouse pointer is over a cell, the cell displays a ToolTip when one of the following conditions is met:
The value of the DataSource property is not a null reference (Nothing in Visual Basic) or the value of the VirtualMode property is true, and a handler for the CellToolTipTextNeeded event sets the DataGridViewCellToolTipTextNeededEventArgs.ToolTipText property to a value other than String.Empty.
The ToolTipText property of the cell has a value other than String.Empty. Setting this property has no effect when there is a CellToolTipTextNeeded event handler because getting the value of the property automatically raises the event and returns the ToolTip text specified in the event handler.
