Asp.net 如何在页面的基类中执行 Page_Load()

发布于04月29日

我有以下业绩表.aspx.cs页面类

public partial class PerformanceFactsheet : FactsheetBase
{
    protected void Page_Load(object sender, EventArgs e)
    {
        // do stuff with the data extracted in FactsheetBase
        divPerformance.Controls.Add(this.Data);
    }
}

其中FactsheetBase的定义为

public class FactsheetBase : System.Web.UI.Page
{
    public MyPageData Data { get; set; } 
    protected void Page_Load(object sender, EventArgs e)
    {
        // get data that's common to all implementors of FactsheetBase
        // and store the values in FactsheetBase's properties
        this.Data = ExtractPageData(Request.QueryString["data"]);            
    }
}

问题是FactsheetBase的页面加载没有执行.

谁能告诉我我做错了什么吗？有没有更好的方法来获得我想要的结果？

谢谢

推荐答案

我们面临着类似的问题，你只需要做register the handler in the constructor. :)次

public class FactsheetBase : System.Web.UI.Page 
{ 

    public FactsheetBase()
    {
        this.Load += new EventHandler(this.Page_Load);
    }

    public MyPageData Data { get; set; }  
    protected void Page_Load(object sender, EventArgs e) 
    { 
        // get data that's common to all implementors of FactsheetBase 
        // and store the values in FactsheetBase's properties 
        this.Data = ExtractPageData(Request.QueryString["data"]);             
    } 
}

另一种方法是设置为override OnLoad()，这不太受欢迎.

public class FactsheetBase : System.Web.UI.Page 
{ 

    public FactsheetBase()
    {
    }

    public MyPageData Data { get; set; }  
    protected override void OnLoad(EventArgs e)
    {
        //your code
        // get data that's common to all implementors of FactsheetBase 
        // and store the values in FactsheetBase's properties 
        this.Data = ExtractPageData(Request.QueryString["data"]);             

        base.OnLoad(e);
    }
}
