.net GridView分頁模板的實例代碼

復制代碼 代碼如下:
//要在GridView中加入如下屬性(前台還是後台看你的習慣了。)

//實現分頁

AllowPaging="true"

//一頁數據10行

 PageSize="10"

// 分頁時觸發的事件
OnPageIndexChanging="gvwDesignationName_PageIndexChanging"

//在服務器事件裡

protected void gvwDesignationName_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
gvwDesignationName.PageIndex=e.newIndex;

bingDesignatioonName();
}

//這裡我給出一個通用顯示分頁的模板

<PagerTemplate>
                當前第:
                //((GridView)Container.NamingContainer)就是為了得到當前的控件
                <asp:Label ID="LabelCurrentPage" runat="server" Text="<%# ((GridView)Container.NamingContainer).PageIndex + 1 %>"></asp:Label>
                頁/共:
                //得到分頁頁面的總數
                <asp:Label ID="LabelPageCount" runat="server" Text="<%# ((GridView)Container.NamingContainer).PageCount %>"></asp:Label>
                頁
                 //如果該分頁是首分頁，那麼該連接就不會顯示了.同時對應了自帶識別的命令參數CommandArgument
                <asp:LinkButton ID="LinkButtonFirstPage" runat="server" CommandArgument="First" CommandName="Page"
                    Visible='<%#((GridView)Container.NamingContainer).PageIndex != 0 %>'>首頁</asp:LinkButton>
                <asp:LinkButton ID="LinkButtonPreviousPage" runat="server" CommandArgument="Prev"
                    CommandName="Page" Visible='<%# ((GridView)Container.NamingContainer).PageIndex != 0 %>'>上一頁</asp:LinkButton>
               //如果該分頁是尾頁，那麼該連接就不會顯示了
                <asp:LinkButton ID="LinkButtonNextPage" runat="server" CommandArgument="Next" CommandName="Page"
                    Visible='<%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %>'>下一頁</asp:LinkButton>
                <asp:LinkButton ID="LinkButtonLastPage" runat="server" CommandArgument="Last" CommandName="Page"
                    Visible='<%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %>'>尾頁</asp:LinkButton>
                轉到第
                <asp:TextBox ID="txtNewPageIndex" runat="server" Width="20px" Text='<%# ((GridView)Container.Parent.Parent).PageIndex + 1 %>' />頁
                //這裡將CommandArgument即使點擊該按鈕e.newIndex 值為3
                <asp:LinkButton ID="btnGo" runat="server" CausesValidation="False" CommandArgument="-2"
                    CommandName="Page" Text="GO" />
            </PagerTemplate>

//對應該事件中代碼為

 protected void gvwDesignationName_PageIndexChanging(object sender, GridViewPageEventArgs e)
    {
        // 得到該控件
        GridView theGrid = sender as GridView;
        int newPageIndex = 0;
        if (e.NewPageIndex==-3)
        {
            //點擊了Go按鈕
            TextBox txtNewPageIndex = null;

            //GridView較DataGrid提供了更多的API，獲取分頁塊可以使用BottomPagerRow 或者TopPagerRow，當然還增加了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
        {
            //點擊了其他的按鈕
            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;

         //重新綁定
        bingDesignatioonName();
    }
