How to limit text string in Eval

Question

I have a hyperlink with the navigate property set like this:

NavigateUrl='<%# Eval("My Text") %>'

How can I limit the string to 140 characters ? I have tried this Eval("My Text").ToString().Substring(0,140) but if the string length is less than 140 characters it throws an exception.

Answer 1

And yet an other possibility:

Eval("My Text").ToString().PadRight(140).Substring(0,140).TrimEnd()

Edit:

I do like LINQ, too:

Eval("My Text").ToString().Take(140).Aggregate("", (x,y) => x + y)
