    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.
