LabelEdit Property

Gets/sets a value indicating whether the text of a UltraTreeNode can be edited by the user.
Syntax
public Infragistics.Win.DefaultableBoolean LabelEdit {get; set;}
Remarks

When LabelEdit resolves to true, clicking (or pressing F2) on the ActiveNode will automatically put the UltraTreeNode into LabelEdit mode.

When LabelEdit resolves to false, LabelEdit mode cannot be entered by user interaction.

To validate data entered into a node, use the ValidateLabelEdit event.

Note: The UltraTreeNode.BeginEdit method can be used to programmatically place an UltraTreeNode into LabelEdit mode. In this case, the value of the LabelEdit property is not applicable.

Note: If the UltraTreeNode is bound to a data source, the LabelEdit property is not applicable unless the UseEditor property resolves to true.

Example
The following sample code illustrates how to set some node behavior options.
