Programatically Select All in TreeViewAdv

How do you programatically select all the nodes in a TreeViewAdv? Do you really have to spin through the whole tree adding them to the treeViewAdv1.SelectedNodes, or is there a faster way? Cheers

Actually.. treeViewAdv1.SelectedNodes.Clear(); treeViewAdv1.SelectedNodes.AddRange(treeViewAdv1.Nodes); this seems to work pretty well...

Sigh.. Nevermind this only adds the top level nodes.. So back to square one.. is there a easy way to select all the nodes programatically? -M

Hi, You could use the TreeViewAdv''s ExtendSelectionTo method for this purpose as shown in the code below : this.treeViewAdv1.SelectedNode = this.treeViewAdv1.TopVisibleNode; this.treeViewAdv1.ExtendSelectionTo(this.treeViewAdv1.LastVisibleNode); Please refer to the test sample attached here that shows how this can be done, and let me know if this meets your requirements. Thanks for your interest in Syncfusion products. Regards, Guru Patwal Syncfusion, Inc.
