Default <%# %> or <%= %>

Hi All,

What is the difference between using <%# %> and <%= %>. I have not found a reasonable explanation for this anywhere. Can anyone help me understand it.

Many thanks

Tahir

There are 3 main differences:

1. <%= expressions are evaluated at render time
2. <%# expressions are evaluated at DataBind() time and are not evaluated at all if DataBind() is not called.
3. <%# expressions can be used as properties in server-side controls. <%= expressions cannot.

For example

<asp:label id="something" text='<%# <variable/function/etc> %>' runat=server />

where as
<asp:label id="something" text='<%= <variable/function/etc> %>' runat=server />

will not work
