  • About this demo
  • C#
  • VB
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%>'); 
You can also assign a specific template to individual nodes on the client:
    function setTemplate(node) 
        node.set_clientTemplate("Node Text: #= Text #");
