Hello,

Unfortunately the three state checkbox do not have disable or readonly states by default.

You can try a workaround with the background image like here:

function OnClientLoad(sender) {
         var $ = $telerik.$;
         var tri = $(".DisabledCheckBox", sender.get_element()).siblings(".rtUnchecked");
         tri.unbind("click");
         tri.css("background-image", "url(/Images/3-state-checkbox-disabled.gif)");
         tri.click(function () {
             return false;
         });

I am attaching the image that is used.

Hope this  will help you.

Thanks for the answer.

Your Code doesnt work 100% for me, but it helped me alot.

1.) It only works for checkboxes that get populated as unchecked because of
var tri = $(".DisabledCheckBox", sender.get_element()).siblings(".rtUnchecked");
2.) I had to swap the checked and unchecked states from your image, because it got loaded wrongly. (Image is attached)

To fix the first point i have modified your code to the following: (improvements are welcome)

function OnClientLoad(sender) {
var $ = $telerik.$;
var arrState = new Array(".rtUnchecked", ".rtChecked", ".rtIndeterminate");

for (var i = 0; i < arrState.length; i++) {
var tri = $(".DisabledCheckBox", sender.get_element()).siblings(arrState[i]);
if (tri != null) {
tri.css("background-image", "url(../Images/3-state-checkbox-disabled.gif)");
tri.unbind("click");
tri.click(function () {
return false;
});
}
}
}

And added the same function to OnClientNodePopulated in my treeView.

<telerik:RadTreeView ID="treeView1" runat="server" OnClientNodePopulated="OnClientLoad" OnClientLoad="OnClientLoad">
</telerik:RadTreeView>

Also i'd like to mention, that this feature was wished for in May 17, 2005. So, i hope it will be added some day.
More than 6 Years is a really long time.
