Hi  You can use the following code snippet to get the Checked Parent nodes and child nodes: private void button1_Click(object sender System.EventArgs e) { Recursion(this.treeView1.Nodes); this.label1.Text=Parent Nodes : +ParentNodes+
+Child Nodes :+ChildNodes; ParentNodes=0; ChildNodes=0; } int ParentNodes=0ChildNodes=0; public void Recursion(TreeNodeCollection nodes) { if(nodes==null) return; foreach(TreeNode node in nodes) { if(node.Nodes.Count>0 && node.Checked) { ParentNodes++; Recursion(node.Nodes); } else if(node.Checked) { ChildNodes++; } else if(node.Nodes.Count>0) Recursion(node.Nodes); } } I cant upload my test sample in this forum. So if you need that sample ask me to this mail id: csharpvijay@gmail.com. let me know if you have any further question. Thanks Vijay
