Asp.Net의 세 가지 페이징 방법 요약-C#.Net 튜토리얼-php.cn

일반적으로 페이징 방법에는 GridView 및 기타 페이징과 같은 asp.net 자체 데이터 표시 공간, aspnetpager와 같은 타사 페이징 제어, 저장 프로시저 페이징 등 세 가지가 있습니다. 다음은 요약입니다.
첫 번째 방법: GridView에 내장된 페이징을 사용하는 것이 가장 간단한 페이징 방법입니다.
프런트 엔드 방법:

<asp:GridView ID="GridView1" AllowPaging="true" runat="server" 
onpageindexchanging="GridView1_PageIndexChanging" PageSize="3"> 
</asp:GridView>

{ 
protected void Page_Load(object sender, EventArgs e) 
{ 
if(!IsPostBack) 
{ 
BindData(); 
} 
} 
protected void BindData() 
{ 
DataTable dt=new DataTable(); 
dt.Columns.Add("ID"); 
dt.Columns.Add("Name"); 
for (int i = 0; i < 10;i++ ) 
{ 
dt.Rows.Add(i.ToString(), i.ToString()); 
} 
this.GridView1.DataSource = dt; 
this.GridView1.DataBind(); 
} 
protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e) 
{ 
this.GridView1.PageIndex = e.NewPageIndex; 
BindData(); 
} 
}

두 번째: 페이징을 위해 개인화된 디스플레이와 함께 AspNetPager.dll을 사용합니다.
이것은 모든 위치에 aspnetpager.dll에 대한 참조를 추가해야 합니다.
프런트 엔드:

<form id="form1" runat="server"> 
<div> 
<asp:GridView ID="GridView1" runat="server" > 
</asp:GridView> 
<webdiyer:AspNetPager ID="AspNetPager1" runat="server" 
CustomInfoHTML="第%CurrentPageIndex%页，共%PageCount%页，每页%PageSize%条" 
FirstPageText="首页" LastPageText="尾页" LayoutType="Table" NextPageText="下一页" 
onpagechanging="AspNetPager1_PageChanging" PageIndexBoxType="DropDownList" 
PagingButtonLayoutType="Span" PrevPageText="上一页" ShowCustomInfoSection="Left" 
ShowPageIndexBox="Always" SubmitButtonText="Go" PageSize="4" TextAfterPageIndexBox="页" 
TextBeforePageIndexBox="转到">

세 번째 방법: 저장 프로시저와 결합된 AspNetPager를 사용합니다. 페이징
이 방법 페이징은 조금 더 복잡하지만 더 많은 양의 데이터를 처리할 수 있습니다.
프런트엔드:

<asp:GridView ID="GridView1" runat="server" CssClass="GridTable" AutoGenerateColumns="false" onrowdatabound="GridView1_RowDataBound" > 
</asp:GridView> 
<webdiyer:AspNetPager ID="AspNetPager1" runat="server" 
CustomInfoHTML="第%CurrentPageIndex%页，共%PageCount%页，每页%PageSize%条" 
FirstPageText="首页" LastPageText="尾页" LayoutType="Table" NextPageText="下一页" 
onpagechanged="AspNetPager1_PageChanged" PageIndexBoxType="DropDownList" 
PagingButtonLayoutType="Span" PrevPageText="上一页" ShowCustomInfoSection="Left" 
ShowPageIndexBox="Always" SubmitButtonText="Go" PageSize="4" TextAfterPageIndexBox="页" 
TextBeforePageIndexBox="转到"> 
</webdiyer:AspNetPager>

this.txtPayPerson1.Text,this.txtTicketNum.Text,this.txtTicketNo.Text,

this.AspNetPager1.RecordCount = ds.Tables[0].Rows.Count;

여기서 사용된 저장 프로시저는 더 복잡합니다. SQL 문을 뷰에 배치할 수 없고, 테이블에서 직접 쿼리할 수 있나요? 결과적으로 이 저장 프로세스가 약간 이상하다는 결과가 나왔습니다. 친구가 이 내용을 본다면 조언을 해줄 수 있기를 바랍니다.
실제로 저장 프로시저의 핵심은 다음과 같습니다.

Create PROCEDURE [dbo].[P_GetPagedOrders2005] 
(@startIndex INT, 
@endindex INT 
) 
AS 
select * from (SELECT ROW_NUMBER() OVER(ORDER BY IPid DESC) AS rownum, 
[IPid],[IPFrom],[IPTo],[IPLocation],[IPCity],[IPToNumber],[IPFromNumber] from IPInfo) as U 
WHERE rownum between @startIndex and @endIndex 
GO
