TreeView Check Nodes and Unselect Nodes

Nov 13 2017 7:56 PM
I have having trouble Checking nodes with the logic below. Can someone tell me what i am missing?
 
private void tvTestSequence_AfterCheck(object sender, TreeViewEventArgs e)
{
if (e.Action != TreeViewAction.Unknown)
{
if (e.Node.Nodes.Count > 0)
{
if (!e.Node.Checked)
{
this.CheckAllChildNodes(e.Node, e.Node.Checked);
}
}
}
if (e.Node.Parent != null)
{
TreeNode n = e.Node;
while (n.Parent != null)
{
if (n.Checked)
{
n.Parent.Checked = true;
}
n = n.Parent;
}
}
}
private void CheckAllChildNodes(TreeNode treeNode, bool nodeChecked)
{
foreach (TreeNode node in treeNode.Nodes)
{
node.Checked = nodeChecked;
if (node.Nodes.Count > 0)
{
this.CheckAllChildNodes(node, nodeChecked);
}
}
}
