Method 1
See this question:
When should I use # and = in ASP.NET controls?
Summary from those answers:
There are a several different ‘bee-stings’:
<%@– 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 callPage.DataBind()in your code-behind.<%--– Server-side comment block<%:– Equivalent to<%=, but it also html-encodes the output.
Method 2
<%# is data binding expression syntax.
<%= resolves the expression returns its value to the block (Embedded code block reference) – effectively shorthand for <% Response.Write(...); %>
Method 3
<%# is the databinding directive, <%= is a shortcut for “Response.Write”
Method 4
<%= x %> is shorthand for Response.Write()
<%# x %> indicates a databind.
<% %> indicates server-executable code.
