Hi Jane, You can programatically select all the nodes in the treeViewAdv with the help of following code snippet. private void button1_Click(object sender, System.EventArgs e) { this.treeViewAdv1.ExtendSelectionTo(this.treeViewAdv1.LastVisibleNode); this.treeViewAdv1.Focus(); } Please take a look at the attached sample and let me if this helps you. Thanks for using syncfusion products. Regards, Deepa.T.S

Hi Deepa,

I need to select all the nodes, not only the visible nodes in the tree. Is there a way.

Thanks in advance.

Hi Jane, Sorry for the inconvenience caused.I do see that the nodes that are not present in the visible area do not get selected. To solve this problem, please use the following code snippet. private void button1_Click(object sender, System.EventArgs e) { foreach (TreeNodeAdv node in this.treeViewAdv1.Root.Nodes) { this.treeViewAdv1.SelectedNodes.Add(node); TreeNodeAdv lastNode = node.LastNode; while (lastNode != null) { this.treeViewAdv1.ExtendSelectionTo(lastNode); lastNode = lastNode.LastNode; } } this.treeViewAdv1.Focus(); } Please take a look at the modified attached sample,and let me know if this meets your requirements.
