Set values ​​always customized to gridview in asp.net c #

Set values ​​always customized to gridview in asp.net c #

need to fill a gridview via code (C #) and want to know how I define the
values ​​for components declared inside of it, like labels,
buttons and linkbuttons. Below is an example of a component that would
fill and I'm not getting:
<asp:Label ID="lbCodigo" CssClass="label label-inverse" runat="server"
Text='<%#Eval("CODIGO") %>'></asp:Label>



Below is the complete gridview:
