}
I have a TreeView with activated checkboxes. The problem is that the standard CssClass keeps the CssText "SelectedStyle" when clicking on the tree node, regardless of whether the checkbox is selected or deselected.
This is confusing for the user.
My idea to overwrite the CssClass via javaScript doesn't work either, neither with .CssClass nor with .CssText.
What can I do?

Hi,
This is not supported directly. The checkbox states are independent from the styles. Specifically:
1. There is no style changes that are associated to checkbox states;
2. All the styles such as SelectedStyle only applies to the "label" portion of the tree node. It does not apply to the checkbox;
3. The TreeNode object is not a DOM object, so you can not modify its style on the client side;
The only thing you can do is to change the TreeNode's Text. For example, if you can use node.setText("<span style='color:red'>test</span>") to display a red "test" in your tree node. However this maybe too overkill in your case.
I did notice that your license subscription has expired. Tech support is covered by the subscription. So if you still have any question, you may wish to consider to renew your subscription to current. This way you can continue receive support and update your version to current.
