Gets the collection of TreeNode objects assigned to the current tree node.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
The property can hold a collection of other TreeNode objects. Each of the tree node in the collection has a property that can contain its own TreeNodeCollection. This nesting of tree nodes can make it difficult to navigate a tree structure. The FullPath property makes it easier to determine your location in a tree.
The following code example removes the selected tree node from one TreeView and adds it to another if both tree node collections are not read-only. When a Button is clicked, the TreeView.SelectedNode is deleted from one TreeView using the Remove method and added to the other TreeView using the Insert method. This example requires that you have two TreeView controls named treeView1 and treeView2, and a Button on a Form.
Private Sub button1_Click(sender As Object, e As EventArgs) Handles button1.Click ' If neither TreeNodeCollection is read-only, move the ' selected node from treeView1 to treeView2. If Not treeView1.Nodes.IsReadOnly And Not treeView2.Nodes.IsReadOnly Then If (treeView1.SelectedNode IsNot Nothing) Then Dim tn As TreeNode = treeView1.SelectedNode treeView1.Nodes.Remove(tn) treeView2.Nodes.Insert(treeView2.Nodes.Count, tn) End If End If End Sub
