How to delete the selected node in the TreeViewAdv control?

Platform: WinForms |
Control: TreeViewAdv |
Published Date: April 30, 2011 |
Last Revised Date: July 10, 2014

 

Trying to delete the selected node by calling:

this.treeViewAdv1.Nodes.Remove(this.treeViewAdv1.SelectedNode);

The above code will only delete the selected node if it is a root node. This is because TreeViewAdv.Nodes collection does not contain all the nodes of the tree, just thelevel 0 nodes. If the node is in a level greater than 0, it is not deleted as it is not contained in the primary Nodes collection. So you instead should call:

C#

TreeViewAdv.SelectedNode.Parent.Nodes.Remove(TreeViewAdv.SelectedNode);

VB

TreeViewAdv.SelectedNode.Parent.Nodes.Remove(TreeViewAdv.SelectedNode)
