In the else part, instead of assigning the entire outer xml , read the name and assign it. Remove the below one. treeNode.Text = xmlNode.OuterXml. Trim (); else //No children, so add the outer xml (trimming off whitespace) treeNode.Text = xmlNode.Name; Hope this helps you !

//Construct the tree here void Button1_Click ( object sender, EventArgs e) { TreeNode rootNode = treeView1.Nodes. Add ( "Root" ); TreeNode colourNode = rootNode.Nodes. Add ( "Colour" ); colourNode.Nodes. Add ( "Red" ); colourNode.Nodes. Add ( "Blue" ); colourNode.Nodes. Add ( "Green" ); TreeNode countryNode = rootNode.Nodes. Add ( "Country" ); countryNode.Nodes. Add ( "India" ); countryNode.Nodes. Add ( "UK" ); countryNode.Nodes. Add ( "USA" ); TreeNode fruitsNode = rootNode.Nodes. Add ( "Fruits" ); fruitsNode.Nodes. Add ( "Apple" ); fruitsNode.Nodes. Add ( "Mango" ); fruitsNode.Nodes. Add ( "Banana" ); treeView1. ExpandAll (); } //Read the value from the xml file and find out in the tree, update the checkboxes. void Button2_Click ( object sender, System.EventArgs e) { //Read the xml value here. string xmlValue = "Country" ; TreeNode root = treeView1.Nodes[ 0 ]; if (root.Nodes.Count > 0 ) { foreach (TreeNode element in root.Nodes) { if (element.Text == xmlValue) { treeView1.SelectedNode = element; treeView1.SelectedNode.Checked = true ; if (element.Nodes.Count > 0 ) { foreach (TreeNode child in element.Nodes) { treeView1.SelectedNode = child; treeView1.SelectedNode.Checked = true ; } } break ; } } } } Hope this helps you.

Please correct me, if I understood incorrectly. Do you want check the parent and check boxes based on the value which is present in the xml file?
