Data Binding code

<% # Cncproject. pub. Left (DataBinder. Eval (Container. DataItem, "title") %>
Data Binding code
Cncproject. pub. Left (string str); Return Value: string.
The function is to remove the APPEND "..." after the character length exceeds 15 characters "...".
Data Binding expression should support function calling, but this code appears at runtime
"Compiler error message: CS1502: the overload method that best matches" cncproject. pub. Left (string) "has some invalid Parameters ".

Or you can.
<% # DataBinder. Eval (Container, "DataItem. title"). ToString (). Length> 15? DataBinder. eval (Container, "DataItem. title "). toString (). subString (0, 15) + "... ": DataBinder. eval (Container, "DataItem. title ") %>

DataBinder. Eval (Container. DataItem, "title") itself is the object's
So you can change cncproject. pub. Left (string str );
Left string (object str)
{
Return str. ToString ();
// Other code
}
