ASP.NET 2.0比以前版本的一个较大的改进,就是提供了母版页。那么它与内容页之间是怎么通讯的呢,可以参照如下事例,就能够实现其功能(代码很简单,就不加注释了 源代码下载 ):
using
System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
// Master页面
public partial class MasterPage:System.Web.UI.MasterPage
{
protected void Page_Load( object sender,EventArgse)
{
}
protected void btnMaster_Click( object sender,EventArgse)
{
Labellbl = this .ContentPlaceHolder1.FindControl( " lblContent " ) as Label;
Response.Write( " <scriptlanguage='javascript'>alert(' " + lbl.Text + " ');</script> " );
}
}
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
// Master页面
public partial class MasterPage:System.Web.UI.MasterPage
{
protected void Page_Load( object sender,EventArgse)
{
}
protected void btnMaster_Click( object sender,EventArgse)
{
Labellbl = this .ContentPlaceHolder1.FindControl( " lblContent " ) as Label;
Response.Write( " <scriptlanguage='javascript'>alert(' " + lbl.Text + " ');</script> " );
}
}
内容页面如下:
using
System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
// 内容页面
public partial class Default2:System.Web.UI.Page
{
protected void Page_Load( object sender,EventArgse)
{
}
protected void btnContent_Click( object sender,EventArgse)
{
Labellbl = this .Page.Master.FindControl( " lblMaster " ) as Label;
Response.Write( " <scriptlanguage='javascript'>alert(' " + lbl.Text + " ');</script> " );
}
}
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
// 内容页面
public partial class Default2:System.Web.UI.Page
{
protected void Page_Load( object sender,EventArgse)
{
}
protected void btnContent_Click( object sender,EventArgse)
{
Labellbl = this .Page.Master.FindControl( " lblMaster " ) as Label;
Response.Write( " <scriptlanguage='javascript'>alert(' " + lbl.Text + " ');</script> " );
}
}
