Limiting the number of characters shown in a Boundfield for gridview

I have a gridview that shows a user's name, a subject, and a date. The .aspx code looks like this:

      <asp:BoundField DataField="UserName" 
            SortExpression="UserName" />
        <asp:BoundField DataField="Subject" 
            SortExpression="Subject" />
        <asp:BoundField DataField="Date" 
            SortExpression="Date" />

If the user enters a subject that is say 200 characters, I don't want it to all show otherwise the page will be stretched like crazy. Is there any way to do a check so that if the subject is more than say 60 characters, the rest is taken off and a ... is just appended on? So the subject would go from say:

This is a realllllllllllllllllllllllly long subject

to

This is a reallllll....

I know how to do it in the C# code behind but not sure how to manipulate it in the .aspx

Try this:

<asp:TemplateField>
    <ItemTemplate>
        <%# ((string)Eval("Subject")).Length < 200? Eval("Subject") :((string)Eval("Subject")).Substring(0,200) + "..."%>)
    </ItemTemplate>
</asp:TemplateField>

Alternatively (and more cleanly) you can (if possible) add a property to your datasource item-class and use that property in normal fashion. Say, your data-source item class is UserMail; then add a public property say TruncatedSubject like:

partial class UserMail
{        
    public string TruncatedSubject
    {
       get
       {
           return Subject.Length < 200? Subject : (Subject.SubString(0,200) + " ...");
       }
    }        
}

then you can use it (TruncatedSubject instead of Subject) like a normal BoundField column.
