Once you get a GridView set up they way you want it, create a theme in the App_Themes folder and create a skin. Just set the skin property on the gridview. That way if you ever want to change it you only have to change it once in the skin file and it will apply to all your gridviews.

GridViewDefault.skin

<mm:mmGridView runat="server" 
        ForeColor="#333333" GridLines="None" IsPostBack="False" SecuritySetup="True"
        UserFieldName="" SkinID="GridViewDefault" CellPadding = 2>
        <FooterStyle CssClass="GridView_Header"  />
        <PagerStyle BackColor="#284775" ForeColor="White" HorizontalAlign="Center" />
        <HeaderStyle CssClass="GridView_Header" ForeColor="Black" Font-Bold="False"/>
        <EditRowStyle BackColor="#FFEEBB" />
        <RowStyle BackColor="#F1F1F1" ForeColor="#333333" Font-Size="small"/>
        <AlternatingRowStyle BackColor="#FFFFFF" ForeColor="#284775"  />
        <SelectedRowStyle BackColor="#C0C0C0" Font-Bold="False" ForeColor="#333333" />
    </mm:mmGridView>
