Use recursion to iterate through the branch and
act accordingly. Here is a small sample that you
can modify.

#region Set Node Checked State
/// <summary>
/// Recursively sets the checked state of this node and all
/// of its child nodes to the passed in desired check state.
/// </summary>
public static void SetNodeCheckedState(TreeNode treeNode,
bool nodeChecked)
{

treeNode.Checked = nodeChecked;

foreach (TreeNode node in treeNode.Nodes)
{
SetNodeCheckedState(node, nodeChecked);
}
}
#endregion
