Data Binding Syntax: <%#     %>


With ASP.NET data binding, you can bind any server control to simple properties, collections, expressions and/or methods. The data binding enables page developers to hierarchically bind control properties to data container values. Code located within a <%# %> code block is only executed when the DataBind method of its parent control container is invoked. The following example demonstrates how to use the data binding syntax within an <asp:datalist runat="server"> control:
