ToolTipText Property

Gets/sets the text that will be displayed in the ToolTip.
Syntax
'Declaration
 
Public Property ToolTipText As String
public string ToolTipText {get; set;}
Remarks

By default, the ToolTipText property will contain the value of of the UltraListViewItemBase.Text property when the ToolTip is being displayed for UltraListViewSubItem, and when the ToolTip is being displayed for an UltraListViewItem when the TipStyle property is set to 'Show'. When the TipStyle property is set to 'Automatic' the value of the UltraListViewItem instance's UltraListViewItemBase.Text property is displayed if it is not fully visible in the user interface. Additionally, the value of the UltraListViewColumnBase.TextResolved property of the UltraListViewSubItemColumn, along with the value of the UltraListViewItemBase.Text property of the corresponding UltraListViewSubItem, is displayed for each of the UltraListViewSubItemColumn instances which are to be displayed as determined by the VisibleInToolTip and SubItemsVisibleInToolTipByDefault properties. The visible order in which the sub-items are displayed is determined by the VisiblePositionInToolTip property.

Example
The following code sample demonstrates how to handle the ToolTipDisplaying event to customize the tooltip that appears when the cursor hovers over an UltraListViewItem:

For an overview of how to handle events in Visual Basic or Visual C#, see Event Handlers in Visual Basic and Visual C#. For specific information and code examples illustrating how to consume events in your application, see Consuming Events in the .NET Framework Developer's Guide.
