TreeNode.NextNode Property

Gets the next sibling tree node.

[Visual Basic]
Public ReadOnly Property NextNode As TreeNode
public TreeNode NextNode {get;}
public: __property TreeNode* get_NextNode();
public function get NextNode() : TreeNode;

Property Value

A TreeNode that represents the next sibling tree node.


The NextNode is the next sibling TreeNode in the TreeNodeCollection stored in the Nodes property of the tree node's parent TreeNode. If there is no next tree node, the NextNode property returns a null reference (Nothing in Visual Basic).


[Visual Basic, C#, C++] The following example selects the appropriate TreeNode after determining if the TreeNode passed in is selected and which TreeNode to select. This example assumes that you have a Form with a TreeView control that has a TreeNodeCollection containing several TreeNode objects. It is also assumed that you have a ComboBox with the following items: "Previous", "PreviousVisible", "Next", "NextVisible", "First", and "Last".

[Visual Basic] 
Private Sub SelectNode(node As TreeNode)
   If node.IsSelected Then
      ' Determine which TreeNode to select.
      Select Case myComboBox.Text
         Case "Previous"
            node.TreeView.SelectedNode = node.PrevNode
         Case "PreviousVisible"
            node.TreeView.SelectedNode = node.PrevVisibleNode
         Case "Next"
            node.TreeView.SelectedNode = node.NextNode
         Case "NextVisible"
            node.TreeView.SelectedNode = node.NextVisibleNode
         Case "First"
            node.TreeView.SelectedNode = node.FirstNode
         Case "Last"
            node.TreeView.SelectedNode = node.LastNode
      End Select
   End If
End Sub

private void SelectNode(TreeNode node)
        // Determine which TreeNode to select.
            case "Previous":
                node.TreeView.SelectedNode = node.PrevNode;
            case "PreviousVisible":
                node.TreeView.SelectedNode = node.PrevVisibleNode;
            case "Next":
                node.TreeView.SelectedNode = node.NextNode;
            case "NextVisible":
                node.TreeView.SelectedNode = node.NextVisibleNode;
            case "First":
                node.TreeView.SelectedNode = node.FirstNode;
            case "Last":
                node.TreeView.SelectedNode = node.LastNode;

void SelectNode(TreeNode* node) {
    if (node->IsSelected) {
        // Determine which TreeNode to select.

        String* str = myComboBox->Text;
        if (str->Equals(S"Previous"))
            node->TreeView->SelectedNode = node->PrevNode;
        else if (str->Equals(S"PreviousVisible"))
            node->TreeView->SelectedNode = node->PrevVisibleNode;
        else if (str->Equals(S"Next"))
            node->TreeView->SelectedNode = node->NextNode;
        else if (str->Equals(S"NextVisible"))
            node->TreeView->SelectedNode = node->NextVisibleNode;
        else if (str->Equals(S"First"))
            node->TreeView->SelectedNode = node->FirstNode;
        else if (str->Equals(S"Last"))
            node->TreeView->SelectedNode = node->LastNode;
