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;
}

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.

Sorry , I posting my c logic code. <code> struct tree { int node ; struct tree *left ; struct tree *right; } ; struct *p; if (p->left !=NULL && p->right !=NULL ) Then p will not be having any child. </code>
