<%@ - Page/Control/Import/Register directive
<%$ - Resource access and Expression building
<%= - Explicit output to page, equivalent to <% Response.Write( ) %>
<%# - Data Binding. It can only used where databinding is supported, or at the page level if you call Page.DataBind() in your code-behind.
<%-- - Server-side comment block
<%: - Equivalent to <%=, but it also html-encodes the output.

 
 

//example.cs
<script runat="server">
	internal string calculate_proper_shipping_cost(object deliveryCost, object specialCost)
	{
		double total = 0;

		if (deliveryCost != null)
			total = double.Parse(deliveryCost.ToString());

		if (specialCost != null)
			total += double.Parse(specialCost.ToString());

		return General.FormatC(total.ToString());
	}
</script>

//when using Data Binding warning the semicolon throws error CS1026: ) expected : 
//proper
<%# calculate_proper_shipping_cost( Eval("DiscountValue"), Eval("DiscountValue"))  %>

//invalid
<%# calculate_proper_shipping_cost( Eval("DiscountValue"), Eval("DiscountValue"));  %>
