  • GridView自定义分页

    第一步:设置GridView的AllowPaging="True" 和 PageSize="20"

    第二步:创建GridView的分页模板

                <PagerTemplate><asp:Label ID="LabelCurrentPage" runat="server" Text="<%# ((GridView)Container.NamingContainer).PageIndex + 1 %>"></asp:Label>/共<asp:Label ID="LabelPageCount" runat="server" Text="<%# ((GridView)Container.NamingContainer).PageCount %>"></asp:Label><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>
                    转到第
                    <asp:TextBox ID="txtNewPageIndex" runat="server" Width="25px" BorderColor="gray"  BorderWidth="1px" Height="15" Text='<%# ((GridView)Container.Parent.Parent).PageIndex + 1 %>' /><asp:LinkButton ID="btnGo" runat="server" CausesValidation="False" CommandArgument="-2"
                        CommandName="Page" Text="GO" />
                </PagerTemplate>

    第三步:在PageIndexChanging事件中添加如下代码

        protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
        {
            // 得到该控件
            GridView theGrid = sender as GridView;
            int newPageIndex = 0;
            if (e.NewPageIndex == -3)
            {
                //点击了Go按钮
                TextBox txtNewPageIndex = null;
                //GridView较DataGrid提供了更多的API,获取分页块可以使用BottomPagerRow 或者TopPagerRow,当然还增加了HeaderRow和FooterRow
                GridViewRow pagerRow = theGrid.BottomPagerRow;
                if (pagerRow != null)
                {
                    //得到text控件
                    txtNewPageIndex = pagerRow.FindControl("txtNewPageIndex") as TextBox;
                }
                if (txtNewPageIndex != null)
                {
                    //得到索引
                    newPageIndex = int.Parse(txtNewPageIndex.Text) - 1;
                }
            }
            else
            {
                //点击了其他的按钮
                newPageIndex = e.NewPageIndex;
            }
            //防止新索引溢出
            newPageIndex = newPageIndex < 0 ? 0 : newPageIndex;
            newPageIndex = newPageIndex >= theGrid.PageCount ? theGrid.PageCount - 1 : newPageIndex;
            //得到新的值
            theGrid.PageIndex = newPageIndex;
            //重新绑定数据
            this.prBindToDataGird();
                  
      }
