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

[BrowsableAttribute(false)]
public TreeNode PrevVisibleNode { get; }

Property Value

Type: System.Windows.Forms.TreeNode

A TreeNode that represents the previous visible tree node.

The PrevVisibleNode can be a child, sibling, or a tree node from another branch. If there is no previous tree node, the PrevVisibleNode property returns null.

The following code example selects the appropriate TreeNode after determining if the TreeNode passed in is selected and which TreeNode to select. This example requires that you have a Form with a TreeView control that has a TreeNodeCollection that contains several TreeNode objects. It also requires that you have a ComboBox with the following items: "Previous", "PreviousVisible", "Next", "NextVisible", "First", and "Last".

private void SelectNode(TreeNode node)
{
	if(node.IsSelected)
	{
		// Determine which TreeNode to select.
		switch(myComboBox.Text)
		{
			case "Previous":
				node.TreeView.SelectedNode = node.PrevNode;
				break;
			case "PreviousVisible":
				node.TreeView.SelectedNode = node.PrevVisibleNode;
				break;
			case "Next":
				node.TreeView.SelectedNode = node.NextNode;
				break;
			case "NextVisible":
				node.TreeView.SelectedNode = node.NextVisibleNode;
				break;
			case "First":
				node.TreeView.SelectedNode = node.FirstNode;
				break;
			case "Last":
				node.TreeView.SelectedNode = node.LastNode;
				break;
		}
	}
	node.TreeView.Focus();
}
