TreeView.LabelEdit Property

Gets or sets a value indicating whether the label text of the tree nodes can be edited.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

member LabelEdit : bool with get, set

Property Value

Type: System.Boolean
true if the label text of the tree nodes can be edited; otherwise, false. The default is false.

The BeginEdit method works only if the LabelEdit property is true. If LabelEdit is false when you attempt to edit the label, an exception will be thrown and the tree node will not be put in to an editable state.

The following code example lets the user edit nonroot tree nodes by using a ContextMenu. When the user right clicks the mouse, the TreeNode at that position is determined and stored in a variable named mySelectedNode. If a nonroot tree node was selected, it is put into an editable state, which allows the user to edit the node label. After the user stops editing the tree node label, the new label text is evaluated and saved. For this example, several characters are considered not valid in the label text. If one of the invalid characters is in the label string, or the string is empty, the user is notified of the error and the label is returned to its previous text.
