You don't have the implementation details of your code, so this is a shot in the dark. If you are binding an object, create a new property that takes the first 100 characters of the information you want displayed:

class Foo 
{
   public String PropertyData {get;set;} //your real data;
   public String DisplayData //bind the reader to this property instead.
   {
       get 
       {
           return PropertyData.substring
            (0, (PropertyData.Length >= 100) ? 100 : PropertyData.Length);
       }
   }
}

You can have the property return anything you want, this is just an example of how to get it to display only 100 characters.

You can leave this logic in the view:

<asp:Label runat="server" 
 Text='<%# DataBinder.Eval(Container.DataItem, "your_text_field").ToString().Substring(0, Math.Min(100, DataBinder.Eval(Container.DataItem, "your_text_field").ToString().Length %>' />
<asp:Hyperlink runat="server" Test='<%# Eval("your_text_field") %>' 
     Visible='<%# Eval("your_text_field").ToString().Length > 100 %>' />
