ascx是一個整體，你要是想使用它的東西，只有三種辦法：屬性、方法和事件
像如要使用它裏面的dg，可以用屬性把dg的應用調出來，下面是我寫個一個例子，你可以看看
用戶控件
usc/dg.ascx
<%@ Control Language="c#" AutoEventWireup="false" Codebehind="dg.ascx.cs" Inherits="startmssql.ucs.dg" TargetSchema="http://schemas.microsoft.com/intellisense/ie5"%> <asp:DataGrid id="dgsy" runat="server"></asp:DataGrid>
usc/dg.ascx.cs
namespace startmssql.ucs
{
using System;
using System.Data;
using System.Drawing;
using System.Web;
using System.Web.UI.WebControls;
using System.Web.UI.HtmlControls;
public class dg : System.Web.UI.UserControl
{
protected System.Web.UI.WebControls.DataGrid dgsy;
private void Page_Load(object sender, System.EventArgs e)
{
// 在此處放置用戶代碼以初始化頁面
}
# Web 窗體設計器生成的代碼
public DataGrid DGrid
{
get
{
return this.dgsy;
}
set
{
this.dgsy=value;
}
}
}
}
具體應用
dgridsy.aspx
<%@ Register TagPrefix="uc1" TagName="dg" Src="ucs/dg.ascx" %> <%@ Page language="c#" Codebehind="dgridsy.aspx.cs" AutoEventWireup="false" Inherits="startmssql.dgridsy" %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" > <HTML> <HEAD> <title>dgridsy</title> <meta name="GENERATOR" Content="Microsoft Visual Studio .NET 7.1"> <meta name="CODE_LANGUAGE" Content="C#"> <meta name="vs_defaultClientScript" content="JavaScript"> <meta name="vs_targetSchema" content="http://schemas.microsoft.com/intellisense/ie5"> </HEAD> <body MS_POSITIONING="GridLayout"> <form id="Form1" method="post" runat="server"> <FONT face="宋體"> <uc1:dg id="dguc" runat="server"></uc1:dg></FONT> </form> </body> </HTML>
dgridsy.aspx.cs
using System.Drawing;
using System.Web;
using System.Web.SessionState;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.HtmlControls;
using System.Data.SqlClient;
using System.Configuration;
namespace startmssql
{
public class dgridsy : System.Web.UI.Page
{
SqlConnection conn=null;
SqlCommand cmd=null;
protected startmssql.ucs.dg dguc;
private void Page_Load(object sender, System.EventArgs e)
{
// 在此處放置用戶代碼以初始化頁面
setup();
}
#窗體設計器生成的代碼
private void setup()
{
string strconn=ConfigurationSettings.AppSettings["wei"];
conn=new SqlConnection(strconn);
string sql="select top 8 * from [authors] order by au_id desc";
cmd=new SqlCommand(sql,conn);
try
{
conn.Open();
dguc.DGrid.DataSource=cmd.ExecuteReader();
dguc.DGrid.DataBind();
}
catch(SqlException ex)
{
Response.Write(ex.Message);
}
finally
{
conn.Close();
}
}
}
}
