GridView中加入//實現分頁

要在GridView中加入//實現分頁server

AllowPaging="true" PageSize="10"索引

// 分頁時觸發的事件
protectedvoid gvwDesignationName_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
gvwDesignationName.PageIndex=e.newIndex;
bingDesignatioonName();
}事件

這裏我給出一個通用顯示分頁的模板（網上搜的，本身給出註釋)io

對應該事件中代碼爲ast

<PagerTemplate>模板

當Ì¡À前¡ã第Ì¨²:object

<asp:Label ID="LabelCurrentPage" runat="server" Text="<%# ((GridView)Container.NamingContainer).PageIndex + 1 %>"></asp:Label>分頁

頁°3/共2:註釋

<asp:Label ID="LabelPageCount" runat="server" Text="<%# ((GridView)Container.NamingContainer).PageCount %>"></asp:Label>vi

頁°3

<asp:LinkButton ID="LinkButtonFirstPage" runat="server" CommandArgument="First" CommandName="Page"

Visible='<%#((GridView)Container.NamingContainer).PageIndex != 0 %>'>首º¡Á頁°3</asp:LinkButton>

<asp:LinkButton ID="LinkButtonPreviousPage" runat="server" CommandArgument="Prev"

CommandName="Page" Visible='<%# ((GridView)Container.NamingContainer).PageIndex != 0 %>'>上¦?一°?頁°3</asp:LinkButton>

<asp:LinkButton ID="LinkButtonNextPage" runat="server" CommandArgument="Next" CommandName="Page"

Visible='<%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %>'>下?一°?頁°3</asp:LinkButton>

<asp:LinkButton ID="LinkButtonLastPage" runat="server" CommandArgument="Last" CommandName="Page"

Visible='<%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %>'>尾2頁°3</asp:LinkButton>

轉Áa到Ì?第Ì¨²

<asp:TextBox ID="txtNewPageIndex" runat="server" Width="20px" Text='<%# ((GridView)Container.Parent.Parent).PageIndex + 1 %>' />頁°3

<asp:LinkButton ID="btnGo" runat="server" CausesValidation="False" CommandArgument="-2"

CommandName="Page" Text="GO" />

</PagerTemplate>

protected void gvwDesignationName_PageIndexChanging(object sender, GridViewPageEventArgs e)
    {
        // 獲得該控件
        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，獲取分頁塊可使用BottomPagerRow 或者TopPagerRow，固然還增長了HeaderRow和FooterRow
            GridViewRow pagerRow = theGrid.BottomPagerRow;

            if (pagerRow != null)
            {
                //獲得text控件
                txtNewPageIndex = pagerRow.FindControl("txtNewPageIndex") as TextBox;
            }
            if ( txtNewPageIndex!= null)
            {
                //獲得索引
                newPageIndex = int.Parse(txtNewPageIndex.Text) - 1;
            }
        }
        else
        {
            //點擊了其餘的按鈕
            newPageIndex = e.NewPageIndex;
        }
        //防止新索引溢出
        newPageIndex = newPageIndex < 0 ? 0 : newPageIndex;
        newPageIndex = newPageIndex >= theGrid.PageCount ? theGrid.PageCount - 1 : newPageIndex;

        //獲得新的值
        theGrid.PageIndex = newPageIndex;

         //從新綁定
        bingDesignatioonName();
    }
