You need to loop through all nodes and their child nodes.

C#

private void CheckChildren(TreeNode node)
{
	foreach (TreeNode n in node.Nodes) {
		n.Checked = node.Checked;
		CheckChildren(n);
	}
}

Passing root node to this function will mark all the nodes as checked/unchecked. You can code it as per your need.
