Simple data binding

<%# Container.DataItem("expression") %>

Any expression that will result in a string will do.

Example

<asp:Label id="label1" runat="server"
     Text='<%# Container.DataItem("CustomerName") %>'
</asp:Label>

Example2

<asp:Label id="label1" runat="server"
     Text='<%# DataBinder.Eval(Container.DataItem
	 			, "OrderDate"
				,"{0:dddd d MMMM}") %>'
</asp:Label>

Using eval

<%# Eval("Price", "{0:C}") %>
<%# Eval("Price", "Special Offer {0:C} for Today Only!") %>
