Body Section like wise

< asp：button id =btn1runat =servertext =点击xmlns：asp =＃unknown>





codeFile有：

<asp:button id="btn1" runat="server" text="Click" xmlns:asp="#unknown">


codeFile have :

protected void Page_Load(object sender, EventArgs e)
      {
          if (Page.IsPostBack)
              userNews.SrcNews = "Chrysanthemum.jpg";
      }

usercontrol修改属性

usercontrol modify the Property

public string SrcNews
{
    get { return imgNews.Attributes["src"];}
    set { imgNews.Attributes["src"] = value;}
}

i希望此代码能够正常工作

i hope this code will work

在您的源代码中，您应该更改 SrcNews 属性如下：

In your source code you should change your SrcNews property like bellow:

public string SrcNews
{
    get { return imgNews.Attributes["src"];}
    set { imgNews.Attributes["src"] = value;}
}

您好

i有一个澄清。在访问您可以创建的属性之前该用户控件的实例并尝试访问该属性SrcNews。



Ex：

您已注册一个名为Usercontrol1的用户控件.ascx。

你明智地编写代码



Usercontrol1 objUserControl = Page.FindControl（Usercontrol1.ascx）;

objUserControl.SrcNews =;





现在您可以访问此属性。

Hi
i have one clarification.before accessing the property you could create the instance for that user control and try to access that property "SrcNews".

Ex:
you have registered one usercontrol called "Usercontrol1.ascx".
you write the code like wise

Usercontrol1 objUserControl=Page.FindControl("Usercontrol1.ascx");
objUserControl.SrcNews="";


now you may access this property.
