GridView的PagerTemplate分页(一)

1、开启GridView的分页功能AllowPaging为Ture.

在Html源设置GridView的PagerTemplate：

<asp:GridView ID="gvProject" runat="server" BorderColor="Gray" Height="20px" Width="98%" AllowPaging="True" AutoGenerateColumns="False" EmptyDataText="没有符合查询条件的数据！" OnDataBound="gvProject_DataBound" OnPageIndexChanging="gvProject_PageIndexChanging" OnRowDataBound="gvProject_RowDataBound" OnRowDeleting="gvProject_RowDeleting">
                                    <EditRowStyle BackColor="SeaGreen" />
                                    <SelectedRowStyle BorderColor="SeaGreen" />
                                    <HeaderStyle BackColor="#718BD6" Font-Size="Small" ForeColor="White" Height="20px" />
                                    <PagerSettings Mode="NumericFirstLast" />
                                    <RowStyle Height="16px" />
                                    <AlternatingRowStyle BackColor="#EDF5FF" />
                                    <Columns>
                                        <asp:BoundField DataField="ProjectID" HeaderText="项目ID" Visible="False" />
                                        <asp:BoundField DataField="ProjectName" HeaderText="项目名称" />
                                        <asp:BoundField DataField="ProjectStatus" HeaderText="项目状态" />
                                        <asp:BoundField DataField="ssjd" HeaderText="实施进度" >
                                            <ItemStyle ForeColor="Red" HorizontalAlign="Center" />
                                        </asp:BoundField>
                                        <asp:BoundField DataField="ssBeginDate" HeaderText="实施开始时间" DataFormatString="{0:d}" HtmlEncode="False" />
                                        <asp:BoundField DataField="ssEndDate" HeaderText="要求结束时间" DataFormatString="{0:d}" HtmlEncode="False" />
                                        <asp:BoundField DataField="UserName" HeaderText="项目负责人" />
                                        <asp:HyperLinkField DataNavigateUrlFields="ProjectID" DataNavigateUrlFormatString="ProjectInfo.aspx?ProjectID={0}"
                                            HeaderText="查看" Text="详细信息" />
                                        <asp:TemplateField HeaderText="操作">
                                            <ItemTemplate>
                                                &nbsp;<asp:ImageButton ID="lbtnDelete" runat="server" CommandName="Delete" ImageUrl="~/Images/drop.gif" />
                                            </ItemTemplate>
                                        </asp:TemplateField>
                                    </Columns>
                                    <EmptyDataRowStyle ForeColor="Red" />
                                    
                                    <PagerTemplate>
                                    当前第:
<asp:Label  ID="LabelCurrentPage" runat="server"
 Text="<%# ((GridView)Container.NamingContainer).PageIndex + 1 %>"></asp:Label>
 页/共:
<asp:Label ID="LabelPageCount" runat="server"
 Text="<%# ((GridView)Container.NamingContainer).PageCount %>"></asp:Label> 页
 
 <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="20px" text='<%# ((GridView)Container.Parent.Parent).PageIndex + 1 %>' />页
<asp:linkbutton id="btnGo" runat="server" causesvalidation="False" commandargument="-1" commandname="Page" text="GO" /> 
                                    </PagerTemplate>
                                    
                                </asp:GridView>

 

 

 设置后台分页事件PageIndexChanging：

protected void gvProject_PageIndexChanging(object sender, GridViewPageEventArgs e)
    {
        //gvProject.PageIndex = e.NewPageIndex;
        //this.BindProjectList();
        GridView theGrid = sender as GridView; // refer to the GridView
        int newPageIndex = 0;
        if (-2 == e.NewPageIndex)
        { // when click the "GO" Button
            TextBox txtNewPageIndex = null;
            //GridViewRow pagerRow = theGrid.Controls[0].Controls[theGrid.Controls[0].Controls.Count - 1] as GridViewRow; // refer to PagerTemplate
            GridViewRow pagerRow = theGrid.BottomPagerRow; //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
            //updated at 2006年月日:15:33
            if (null != pagerRow)
            {
                txtNewPageIndex = pagerRow.FindControl("txtNewPageIndex") as TextBox;   // refer to the TextBox with the NewPageIndex value
            }
            if (null != txtNewPageIndex)
            {
                newPageIndex = int.Parse(txtNewPageIndex.Text) - 1; // get the NewPageIndex
            }
        }
        else
        { // when click the first, last, previous and next Button
            newPageIndex = e.NewPageIndex;
        }
        // check to prevent form the NewPageIndex out of the range
        newPageIndex = newPageIndex < 0 ? 0 : newPageIndex;
        newPageIndex = newPageIndex >= theGrid.PageCount ? theGrid.PageCount - 1 : newPageIndex;
        // specify the NewPageIndex
        theGrid.PageIndex = newPageIndex;
        // rebind the control
        // in this case of retrieving the data using the xxxDataSoucr control,
        // just do nothing, because the asp.net engine binds the data automatically
        this.BindProjectList();//数据绑定的方法
    }

 

 这样就OK了
