  • huh?

This example demonstrates how to bind RadListBox to Entity Framework data. 

<telerik:RadListBox runat="server" ID="RadListBox1" Height="200px" Width="200px"
	DataSourceID="EntityDataSource1" DataTextField="ContactName">
</telerik:RadListBox>
<asp:EntityDataSource ID="EntityDataSource1" runat="server" 
	ConnectionString="name=NorthwindReadWriteEntities"
	DefaultContainerName="NorthwindReadWriteEntities" 
	EntitySetName="Customers" 
	Select="it.[ContactName], it.[City], it.[ContactTitle]"
	AutoPage="true" OrderBy="it.[ContactName]">
</asp:EntityDataSource>
