Using '<%# Eval(“item”) %>'; Handling Null Value and showing 0 against

Question

If dataitem is Null I want to show 0

\' runat=\"server\">

        

Answer 1

Use IIF.

<asp:Label ID="Label18" Text='<%# IIF(Eval("item") Is DBNull.Value,"0", Eval("item") %>' 
runat="server"></asp:Label>

Answer 2

I use the following for VB.Net:

<%# If(Eval("item").ToString() Is DBNull.Value, "0 value", Eval("item")) %>

Answer 3

It should work as well

Eval("item") == null?"0": Eval("item");

Answer 4

try this code it might be useful -

<%# ((DataBinder.Eval(Container.DataItem,"ImageFilename").ToString()=="") ? "" :"<a
 href="+DataBinder.Eval(Container.DataItem, "link")+"><img
 src='/Images/Products/"+DataBinder.Eval(Container.DataItem,
 "ImageFilename")+"' border='0' /></a>")%>

Answer 5

Used a modified version of Jason's answer:

public string ProcessMyDataItem(object myValue)
{
  if (myValue.ToString().Length < 1)
  {
     return "0 value";
  }

  return myValue.ToString();
}

Answer 6

I don't know ASP.NET very well, but can you use the ternary operator?

http://en.wikipedia.org/wiki/Ternary_operation

Something like: (x=Eval("item")) == Null ? 0 : x
