Hi,
According to your post, my understanding is that you want to hide/show the TreeView when the Checkbox checked/unchecked.
We can use jQuery to achieve it, the following script for your reference:
<script src="http://code.jquery.com/jquery-1.10.2.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(function () {
$("input[type=checkbox]").click(function () {
if (this.checked) {
$("#TreeViewID").hide();
} else {
$("#TreeViewID").show();
</script>
