Hi Rick,
You can avoid the image displaying in the tree, while collapsing the Last Parent Node of last node by handling the BeforeCollapse event handler
private void treeViewAdv1_BeforeCollapse(object sender, Syncfusion.Windows.Forms.Tools.TreeViewAdvCancelableNodeEventArgs e)
{
if(!this.treeViewAdv1.SelectedNode.HasChildren)
this.treeViewAdv1.SelectedNode=this.treeViewAdv1.SelectedNode.Parent;
}
Please take a look at the attached sample and let me know if this helps you.
Thanks for your continued interest in Syncfusion products.
Regards,
Deepa.T.S
