  • About this demo
  • C#
  • VB

RadListBox now supports client templates. The templates are declared in the ClientItemTemplate 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 items loaded through web service. To apply a client template to an arbitrary item, you have to call the bindTemplate() function on that item:

function addItem(itemText) {
	var item = new Telerik.Web.UI.RadListBoxItem();
	var list = $find('<%=RadListBox1.ClientID%>');
	item.set_text(itemText);
	list.get_items().add(item);
	item.bindTemplate();
}

You can also define a specific template to individual items on the client:

function setTemplate(item) {
	item.set_clientTemplate("Item Text: #= Text #");
	item.bindTemplate();
}
