    For tri-state TreeView i am trying to check state of 'parent' node.

    I tried get_checked() function, but it returns true for both checked and part-checked items

    Here is the code just in case:

    function rddtRegion_OnClientNodeChecking(sender, args) {

             var region_node = args.get_node();

             if (region_node.get_value().includes('000')) {      // PARENT NODE CHECK

                  if (region_node.get_checked()) {        

     Thank you

    Hello David,

    The TreeNode client-side object has a .get_checkState() method which can be used to determine the exact state of the node:;

    get_checkState none Telerik.Web.UI.TreeNodeCheckState Returns the current check state of a node. It can be one of the following:
    - Telerik.Web.UI.TreeNodeCheckState.Unchecked(i.e. 0);
    - Telerik.Web.UI.TreeNodeCheckState.Checked(i.e. 1);
    - Telerik.Web.UI.TreeNodeCheckState.Indeterminate(i.e. 2);
