The event handler receives an argument of type CellToolTipTextNeededEventArgs containing data related to this event. The following CellToolTipTextNeededEventArgs properties provide information specific to this event.
| Property | Description |
|---|---|
| CellIndex | Gets the cell index in its parent Section. (Inherited from GrapeCity.Win.MultiRow.CellEventArgs) |
| CellName | Gets the cell name. (Inherited from GrapeCity.Win.MultiRow.CellEventArgs) |
| RowIndex | Gets the index of the owner Row that the event occurs for. (Inherited from GrapeCity.Win.MultiRow.CellEventArgs) |
| Scope | Gets the area of the cell that the event occurs for. (Inherited from GrapeCity.Win.MultiRow.CellEventArgs) |
| SectionIndex | Gets the index of the owner Section that the event occurs for. (Inherited from GrapeCity.Win.MultiRow.CellEventArgs) |

This event only can be fired when the VirtualMode property is true or the DataSource property is not a null reference (Nothing in Visual Basic).
When you handle the CellToolTipTextNeeded event, the ToolTip text you specify in the handler is shown whenever the mouse pointer is over a cell and the control ShowCellToolTips property value is true. The CellToolTipTextNeeded event is useful when you want to display ToolTips determined by the current state or value of a cell.
You can use the CellToolTipTextNeededEventArgs's properties to determine the state or value of a cell, and use this information to change or modify the CellToolTipTextNeededEventArgs.ToolTipText property. This property is initialized with the value of the cell CellToolTipTextNeededEventArgs.ToolTipText property, which the event value overrides.
