Message must only show the first 20 characters, how?

 

Hi all,

 

Im trying to build a forum in asp.net 2.0. (Im pretty new with asp.net)

I list all my messages on one page but I want that only the first 20 characters are displayed (follow with ... and a "read more link")

This is my code:

 <asp:repeater id="rptnieuws" Runat="server">
                 <ItemTemplate>
                <div class="column1-unit">
                  <h1 class="subtitle"><%#Container.DataItem("nieuwstitel")%></h1>                 &n ...
