Question

What is the syntax to concatenate text into a binding expression for an asp.net webpage (aspx).

For example if I had a hyperlink that was being bound like this:

<asp:HyperLink id='lnkID' NavigateUrl='<%# Bind('Link') %>' Target='_blank'                          Text='View' runat='server'/> 

How do you change, say, the Text to concatenate a bound value with a string? Variations like this aren’t quite right.

Text='<%# Bind('ID') + ' View' %>' 

neither does

Text='<%# String.Concat(Bind('ID'), ' View') %>'

You can also place the ‘concatenation’ in the text portion of a tag if using a template field:

<asp:TemplateField HeaderText='Name' SortExpression='sortName'> <ItemTemplate>    <asp:LinkButton ID='lbName' runat='server' OnClick='lbName_Click' CommandArgument='<%# Eval('ID') %>'>          <%--Enter any text / eval bindind you want between the tags--%>          <%# Eval('Name') %> (<%# Eval('ID') %>)    </asp:LinkButton> </ItemTemplate> 

This results in output like:

Name (ID)

inside of the template column.
