Answer 1

PagerPosition Enumeration - TopAndBottom

このプロパティは両方でページャーを表示しますTop and Bottom

MARK UP

<PagerTemplate>
    <asp:LinkButton ID="LinkButton1" runat="server" 
                CommandName="Page" CommandArgument="First">First</asp:LinkButton>
    <asp:Label ID="pmore" runat="server" Text="..."></asp:Label>
    <asp:LinkButton ID="LinkButton2" runat="server" 
                CommandName="Page" CommandArgument="Prev">Pre</asp:LinkButton>
    <asp:LinkButton ID="p0" runat="server" >LinkButton</asp:LinkButton>
    <asp:LinkButton ID="p1" runat="server" >LinkButton</asp:LinkButton>
    <asp:LinkButton ID="p2" runat="server" >LinkButton</asp:LinkButton>
    <asp:Label ID="CurrentPage" runat="server" Text="Label"></asp:Label>
    <asp:LinkButton ID="p4" runat="server" >LinkButton</asp:LinkButton>
    <asp:LinkButton ID="p5" runat="server" >LinkButton</asp:LinkButton>
    <asp:LinkButton ID="p6" runat="server" >LinkButton</asp:LinkButton>
    <asp:LinkButton ID="LinkButton3" runat="server" 
                CommandName="Page" CommandArgument="Next">Next</asp:LinkButton>
    <asp:Label ID="nmore" runat="server" Text="..."></asp:Label>
    <asp:LinkButton ID="LinkButton4" runat="server" 
                CommandName="Page" CommandArgument="Last">Last</asp:LinkButton>

Answer 2

GridView プロパティ内には、PaggerSettings と呼ばれるものがあります。この中には、FirstPageImageUrl、LastPageImageUrl などがあります。このフィールドには、必要なコーナーと背景を含む画像を配置する必要があります。
