<PagerTemplate><div style="text-align:center; color:Blue">
      <asp:LinkButton ID="cmdFirstPage" runat="server" CommandName="Page" CommandArgument="First"
       Enabled="<%# ((GridView)Container.Parent.Parent).PageIndex!=0 %>">首页</asp:LinkButton>
      <asp:LinkButton ID="cmdPreview" runat="server" CommandArgument="Prev" CommandName="Page"
       Enabled="<%# ((GridView)Container.Parent.Parent).PageIndex!=0 %>">前页</asp:LinkButton>
      第<asp:Label ID="lblcurPage" ForeColor="Blue" runat="server" Text=‘<%# ((GridView)Container.Parent.Parent).PageIndex+1  %>‘></asp:Label>页/共<asp:Label
       ID="lblPageCount" ForeColor="blue" runat="server" Text=‘<%# ((GridView)Container.Parent.Parent).PageCount %>‘></asp:Label>页
      <asp:LinkButton ID="cmdNext" runat="server" CommandName="Page" CommandArgument="Next"
       Enabled="<%# ((GridView)Container.Parent.Parent).PageIndex!=((GridView)Container.Parent.Parent).PageCount-1 %>">后页</asp:LinkButton>
      <asp:LinkButton ID="cmdLastPage" runat="server" CommandArgument="Last" CommandName="Page"
       Enabled="<%# ((GridView)Container.Parent.Parent).PageIndex!=((GridView)Container.Parent.Parent).PageCount-1 %>">尾页</asp:LinkButton>
       &nbsp;<asp:TextBox ID="txtGoPage" OnTextChanged="txtGoPage_TextChanged" runat="server" Text=‘<%# ((GridView)Container.Parent.Parent).PageIndex+1 %>‘
       Width="32px"  CssClass="inputmini"></asp:TextBox>页<asp:Button ID="Button3" runat="server"
           OnClick="Turn_Click" Text="转到" /></div>
</PagerTemplate> 
</asp:GridView>

protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
       GridView1.PageIndex = e.NewPageIndex;
       bind();//对GridView进行再次绑定，该函数由自己编写
}
protected void Turn_Click(object sender, EventArgs e)
{
        GridView1.PageIndex = int.Parse(((TextBox)GridView1.BottomPagerRow.FindControl("txtGoPage")).Text)-1;
        bind();//对GridView进行再次绑定，该函数由自己编写
