When you want the output of an Eval to be something other than the exact
data from the datasource, do something like this:
<asp:HyperLin k id="lnkEmail" runat="server" text='<%#
DataBinder.Eval (Container, "DataItem.email ") %>' NavigateUrl='<% #
DataBinder.Eval (Container, "DataItem.email ","MAILTO:{ 0}")
%>'></asp:HyperLink>
Notice that in the Eval used in the NavigateUrl there are three parameters:

Container (this will always be the same, do not change it)
"DataItem.email "
"MAILTO:{0} "

In the last parameter, create a string which formats the output. Place {0}
wherever you want the data from the datasource to appear. For example, in my
example, you would get something like:

MAILTO:nj****** **@hotmail.com

For more detail, see the documentation. If you have any questions, feel free
to ask and I will do my best to help. Good Luck!
