Question

一个自动分页的 DataGridView1 已经有数据了，比如自动 分了 X页
求 DataGridView1  的总记录数，每页的分页行数，当前所在的页
要 用DataGridView1  的属性取，而不再用SQL语句向数据库中取

Answer 1

--gridview的属性
<PagerTemplate>
                       <table  style="width:100%" border="1">
                            <tr>
                               <td>
                                <asp:LinkButton ID="LinkButtonFirstPage" runat="server" CommandArgument="First" CommandName="Page" 
                                        Visible="<%# ((GridView)Container.NamingContainer).PageIndex != 0 %>">首页</asp:LinkButton> 
                                <asp:LinkButton ID="LinkButtonPreviousPage" runat="server" CommandArgument="Prev" CommandName="Page" 
                                        Visible="<%# ((GridView)Container.NamingContainer).PageIndex != 0 %>">上一页</asp:LinkButton> 
                                <asp:LinkButton ID="LinkButtonNextPage" runat="server" CommandArgument="Next" CommandName="Page" 
                                        Visible="<%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %>">下一页</asp:LinkButton> 
                                <asp:LinkButton ID="LinkButtonLastPage" runat="server" CommandArgument="Last" CommandName="Page" 
                                        Visible="<%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %>">尾页</asp:LinkButton> 
                                <asp:Label ID="LabelLabelCurrentPage1" runat="server"  ForeColor ="RoyalBlue">第</asp:Label>
                                <asp:Label  ID="LabelCurrentPage" runat="server" ForeColor ="RoyalBlue"
                                        Text="<%# ((GridView)Container.NamingContainer).PageIndex + 1 %>"></asp:Label> 
                                <asp:Label ID="LabelPageCount1" runat="server" ForeColor ="RoyalBlue" >/</asp:Label>
                                <asp:Label ID="LabelPageCount" runat="server" ForeColor ="RoyalBlue"
                                        Text="<%# ((GridView)Container.NamingContainer).PageCount %>"></asp:Label> 
                                <asp:Label ID="Label2" runat="server" ForeColor ="RoyalBlue" >页</asp:Label>

 /// <summary>

Answer 3

就现有的GridView1的数据，不再用SQL语句 那怎么得到总的记录数呢，

Answer 4

DataSet ds = (DataSet)GridView1.DataSource;
ds.Table[0].Rows.Count就是总记录数了

Answer 5

DataSet ds = (DataSet)GridView1.DataSource; 
ds.Table[0].Rows.Count就是总记录数了
这放在 gridviewbound 中这一次访问时没数据，放在哪里第一次访问页面能显示多少条记录？
