Hi..
How to check the selected TreeView node is a parent node or not ?

I am implementing a drag and drop facility to in the TreeView. Condition is if the parent node tries to drag it should not allow, only the child should allow to move to any other parent.

Thanks in advance

Check for

(TreeView.SelectedNode.LastNode!=null) // means its parent


or
(TreeView.SelectedNode.Nodes.Count >0l) //,means it has some nodes ..its a parent

You might also want to check first that SelectedNode itself isn't null...

if (TreeView1.SelectedNode != null)
{
    if (TreeView1.SelecedNode.Parent != null)
   {
      // the TreeNode is a child...
   }
}
