If I have...

<TD><%# DataBinder.Eval(Container.DataItem, "Print_name")
%></TD>

and I want to display only the first 12 characters of the "Print_name" data
field, how is that done?
 
Create a Property in the Container that returns the first 12 characters of
the "Print_Name" data, and refer to that property.

Write a function (this is for VB):

Function Truncate(o As Object) As String
Return Left(o.ToString(),12)
End Function

Then, use this binding syntax:

<%# Truncate(DataBinder.Eval(Container.DataItem, "Print_name")) %>
 
Hi David,

Helper functions are great, but for such a simple thing, I use the ever
helpful latebinding:

<%# Container.DataItem.Print_name.substring(0,12) %>

it'll work assuming Print_name can be converted to a string, and length is
= 12 -- and if you cant be certain of those, then add logic to the <%#

expression, or resort to the helper function.
