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

C#

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

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.
