    Client Templates

    • Group A
    • Group B
    • Group C
    • Group D
    RadTreeView now supports client templates. The templates are declared in the ClientNodeTemplate tag and support the following expressions for evaluating code:
    • #= ... # - Data - Evaluates the Javascript code expression or a string property from the data item and outputs the result in the template.
    • # ... # - Code - Evaluates the JavaScript code expression inside. Does not output value.
    • #: ... # - HTML-encode - Same as the data expression, but HTML-encodes the result.
    The templates are applied automatically to all nodes loaded through web service. To apply a client template to an arbitrary node, you have to call the bindTemplate() function on that node: 
        function addNode(nodeText) 
    {
        var node = new Telerik.Web.UI.RadTreeNode();
        var tree = $find('<%=RadTreeView1.ClientID%>'); 
        node.set_text(nodeText);
        node.bindTemplate();
        tree.get_nodes().add(node);
    }
    You can also assign a specific template to individual nodes on the client: 
        function setTemplate(node) 
    {
        node.set_clientTemplate("Node Text: #= Text #");
        node.bindTemplate();
    }
