Disable/enable clientside all checkboxes in a Telerik RadTreeView

Question

I need to disable all checkboxes that I have in telerik RadTree. How I could achieve that?

Trick is, these are not HTML controls but seem to be something imitating these via images, CSS and javascript. For instance, HTML for a RadTreeView node looks like:

  <div class="rtMid">
  <span class="rtSp"></span>
  <span class="rtMinus"></span>
  <span class="rtUnchecked"></span>
  <span class="rtIn">Item text</span>
  </div>

Best, Askar

Do you need this done server side or client side? – dst3p Apr 18 '13 at 18:49 — dst3p, Apr 18 '13 at 18:49
client, since server should be pretty easy – onkami Apr 18 '13 at 19:33 — onkami, Apr 18 '13 at 19:33

Simply redefine its onclick javascript event so it doesn't fire.

This is supposed to work in every browser:

onclickEvent = "if (event.cancelable) {event.preventDefault();}else {event.returnValue = false;} return false;";

This is what I think is the best cross-browser solution:

onclickEvent = "this.checked = !this.checked;";

Add this attribute from code behind, to every RadTreeView node you want to prevent from being checked. – Francis P Apr 18 '13 at 15:44
