this is how to check all the children

    protected void TreeView1_SelectedNodeChanged(object sender, EventArgs e)
    {
        TreeView tv = (TreeView)sender;
        TreeNode tn = tv.SelectedNode;
        CheckAllChildNodes(tn);
    }

    public void CheckAllChildNodes(TreeNode child)
    {
        foreach (TreeNode n in child.ChildNodes)
        {
            n.Checked = true;
            CheckAllChildNodes(n);
        }
    }

I am not sure how to post pack the page on check/uncheck) box

to do the post back you can modify the javascript in the above links and call the __doPostBack(eventTarget, eventArgument) from their code,

there is a bit of work here - I am just putting you on the right track, or just wade around google to find the solution to the post back
