This works:

<asp:Label ID="asdf" runat="server" Text='<%# Eval("Image1") %>'></asp:Label>

displaying data like: L8_Pic_1.jpg

This doesn’t:

<asp:Label ID="asdfaf111" runat="server" Text='<%# Eval("Image1").ToString() %>'></asp:Label>

It gives an Object Reference not set to an instance of an object error

I’m aiming to do this:

String.IsNullOrEmpty(Eval("Image1").ToString()) ? "noImage.jpg" : Eval("Image1")

    You’re looking for the null coalesce operator. It allows you to do just that pattern with ??:

    <%# Eval("Image1") ?? "noImage.jpg" %>
    

    This evaluates as: if Eval(“Image1”) is not null, return it, otherwise return “noImage.jpg”.
