ComboBox - WCF Web Service

  1. Open the combobox to get the first 10 items.
  2. Click the button in the dropdown to load the next 10 items.
  3. Type in some text to filter.

This example demonstrates how to populate RadComboBox from WCF Web Service. You need to point to an existing web service and method:

<telerik:RadComboBox runat="server" ID="RadComboBox1" Height="100px" Skin="Vista"
	<WebServiceSettings Path="ComboBoxWcfService.svc" Method="LoadData" />
Show code in new window Demo isolation steps
<%@ Page Language="C#"  %>
<%@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %>
