GridView 分頁實現方法

GridView分頁功能其實非常簡單。這是一個簡單的分頁實現，給需要的做個參考。基於一下的思路很容易就可以做強大的分頁出來 頁面代碼：

1. <asp:GridView ID="gv_unionlist" runat="server" AutoGenerateColumns="False" Width="100%" OnRowDataBound="gv_unionlist_RowDataBound" OnRowCommand="gv_unionlist_RowCommand" AllowPaging="True" OnRowCreated="gv_unionlist_RowCreated" PageSize="2">
2.                     <Columns>
3.                         <asp:BoundField DataField="ID" HeaderText="ID" />
4.                         <asp:BoundField DataField="unionid" HeaderText="會員號" />
5.                         <asp:BoundField DataField="username" HeaderText="使用者名稱" />
6.                         <asp:BoundField DataField="company" HeaderText="公司名" />
7.                         <asp:BoundField DataField="dutyman" HeaderText="業務負責人" />
8.                         <asp:BoundField DataField="dutymanmobile" HeaderText="業務負責人手機" />
9.                         <asp:TemplateField HeaderText="全選">
10.                             <ItemTemplate>
11.                                 <asp:CheckBox ID="CheckBox1" runat="server" />
12.                             </ItemTemplate>
13.                         </asp:TemplateField>
14.                         <asp:TemplateField HeaderText="訂單情況">
15.                             <ItemTemplate>
16.                                 <asp:LinkButton ID="lb_Orders" runat="server">查看訂單</asp:LinkButton>
17.                             </ItemTemplate>
18.                         </asp:TemplateField>
19.                         <asp:TemplateField HeaderText="房態修改">
20.                             <ItemTemplate>
21.                                  <asp:Button ID="tb_RoomStatus" runat="server" CommandName="RoomStatus" Text='<%#bind("RoomStatusFlag") %>' OnClientClick="return confirm('修改房態修改狀態?');" />
22.                             </ItemTemplate>
23.                         </asp:TemplateField>
24.                         <asp:TemplateField HeaderText="自動滿房">
25.                             <ItemTemplate>
26.                                  <asp:Button ID="tb_AutoFullRoom" runat="server" CommandName="AutoFullRoom"  Text='<%#bind("AutoFullRoomFlag") %>' />
27.                             </ItemTemplate>
28.                         </asp:TemplateField>
29.                         <asp:TemplateField HeaderText="操作">
30.                             <ItemTemplate>
31.                                 <asp:LinkButton ID="lb_Del" runat="server" OnClientClick="return confirm('刪除此記錄?')" CommandName="del">刪除</asp:LinkButton>
32.                             </ItemTemplate>
33.                         </asp:TemplateField>
34.                         <asp:HyperLinkField DataNavigateUrlFields="id" DataNavigateUrlFormatString="~/Admin/Union.aspx?action=update&id={0}"
35.                             HeaderText="確認與修改" Text="確認與修改" />
36.                         <asp:BoundField DataField="registerdt" HeaderText="註冊時間" />
37.                         <asp:BoundField DataField="lastlogindt" HeaderText="最後登陸時間" />
38.                         <asp:BoundField DataField="logincount" HeaderText="登陸次數" />
39.                     </Columns>
40.                     <PagerSettings Position="TopAndBottom" />
41.                     <PagerTemplate>
42.                         <table style="width: 100%">
43.                             <tr>
44.                                 <td align="right">
45.                                     當前頁：<asp:DropDownList ID="dl_pager" runat="server" AutoPostBack="True" OnSelectedIndexChanged="dl_pager_SelectedIndexChanged">
46.                                     </asp:DropDownList>/每頁：<asp:Label ID="lb_pagesize" runat="server"></asp:Label>
47.                                     條</td>
48.                             </tr>
49.                         </table>
50.                     </PagerTemplate>
51.                 </asp:GridView>

 

CS代碼：

1.  protected void gv_unionlist_RowDataBound(object sender, GridViewRowEventArgs e)
2.     {
3.         if (e.Row.RowType == DataControlRowType.Pager)
4.         {
5.             ((DropDownList)e.Row.FindControl("dl_pager")).Items.Clear();
6.             ((Label)e.Row.FindControl("lb_pagesize")).Text = gv_unionlist.PageSize.ToString();
7.             for (int i = 0; i < this.gv_unionlist.PageCount; i++)
8.             {
9.                 ListItem item = new ListItem(Convert.ToString(i + 1), i.ToString());
10.                 if (item.Value == this.gv_unionlist.PageIndex.ToString())
11.                     item.Selected = true;
12.                 ((DropDownList)e.Row.FindControl("dl_pager")).Items.Add(item);
13.             }
14.         }
15. }
17. protected void dl_pager_SelectedIndexChanged(object sender, EventArgs e)
18.     {
19.         if (this.gv_unionlist.PageIndex != Convert.ToInt32(((DropDownList)gv_unionlist.TopPagerRow.FindControl("dl_pager")).SelectedValue))
20.             this.gv_unionlist.PageIndex = Convert.ToInt32(((DropDownList)gv_unionlist.TopPagerRow.FindControl("dl_pager")).SelectedValue);
21.         else if (this.gv_unionlist.PageIndex != Convert.ToInt32(((DropDownList)gv_unionlist.BottomPagerRow.FindControl("dl_pager")).SelectedValue))
22.             this.gv_unionlist.PageIndex = Convert.ToInt32(((DropDownList)gv_unionlist.BottomPagerRow.FindControl("dl_pager")).SelectedValue);
23.         this.searchUnion();
24.     }
