Solution 1

When the string is shorter than 39, this will give an exception "Index and length must refer to a location within the string."

this should work :

REPLACE

Eval("Title").ToString().Substring(0,39)

with this

(Eval("Title").ToString().Length > 39) ? Eval("Title").ToString().Substring(0, 39) : Eval("Title")

you're missing a '(' in the beginning, just before Eval :

(Eval("Title").ToString().Length > 39) ? Eval("Title").ToString().Substring(0, 39) : Eval("Title")

Solution 3

< % #GetTitle(Eval("Title"))%>
public string GetTitle(object title)
{
string _title=Convert.Tostring(title);
       if(_title.Length>39)
{
           return  _title.SubString(0,39);
}
else
{
 return _title;
}
}
