Public Event Hiding As CancelEventHandler
The Hiding event's data class is CancelEventArgs. The following properties provide information specific to this event:
| Property | Description |
|---|---|
| Cancel | Gets or sets a value indicating whether the event should be canceled. |
The toolbar’s visibility depends on the distance from the mouse cursor to the toolbar (see the RibbonMiniToolbarOpacityOptions.OpacityDistance topic). When the distance is greater than the RibbonMiniToolbarOpacityOptions.TransparencyDistance value, the toolbar becomes hidden and closed. You can use the Hiding event to prevent the toolbar from being closed.
If the Cancel parameter is set to true , the toolbar is hidden, but not closed. When you move the mouse back to the toolbar, the toolbar becomes visible again. If the Cancel parameter is left set to false , the toolbar is hidden and closed. You can display the toolbar again by calling the RibbonMiniToolbar.Show method.
