find parent node in treeview

Question

Im using treeview in asp.net

how can i check if parent contains childnodes in treeview selected node changed event.

Answer 1

Check All the child pointer values, whether is it NULL or not.

If all child pointer value is NULL , you can ensure that the parent does not have any child.

Answer 2

In case you want to look if the parent of the selected node contains other children nodes, it is safe to say

bool ContainsOtherChildren = treeView1.SelectedNode.Parnet.ChildNodes.Count > 1;

since you know that it already has at least one child node (the selected one)

I would however make another check if there is indeed a parent such as

if(treeView1.SelectedNode.Parent != null)
{
   ContainsOtherChildren = treeView1.SelectedNode.Parnet.ChildNodes.Count > 1;
}
