1. How can I get my datagrid to only show the Name and not the ID column?

 <asp:GridView ID="GridView1" runat="server" AllowPaging="True" AllowSorting="True"
        AutoGenerateColumns="False" >
 <Columns>
 <asp:BoundField  DataField="EmployeeID" HeaderText="EmployeeID" ReadOnly="True" SortExpression="EmployeeID" />
               <asp:TemplateField HeaderText="EmployeeID" SortExpression="EmployeeID" Visible="false">
</asp:TemplateField>

2. Also if I have a column named First Name in my datafrid how can I get name to show up in that column and not in a new one or how can I assign custom names to my datagrid?

1. You could change your query to fetch only the name.
