一.添加用户控件

1.在项目工程中添加-》新建项-》Silverlight用户控件（SilverlightControl.xaml）

 2.Page 页中
<UserControl x:Class="UserControlDemo.Page"
  xmlns:jl="clr-namespace:UserControlDemo;assembly=UserControlDemo">
使用：
 <jl:SilverlightControl x:Name="HomeAddress" />

 

二.清除用户控件的方法

1.用户控件部分

public partial class SilverlightControl : UserControl
    {
public class AddressEventArgs : RoutedEventArgs
        {
public object Tag { get; set; }
public AddressEventArgs(object tag)
            {
this.Tag=tag;
            }
        }
public delegate void AddressEventHandler(object o, AddressEventArgs e);
public event AddressEventHandler Closed;
void Close_Click(object sender, RoutedEventArgs e)
        {
// remove this from the parent's children collection
            Panel parent = this.Parent as Panel;
if (parent != null)
            {
                parent.Children.Remove(this);
// alert the parent that we closed 
                if (Closed != null)
                {
                    Closed(this, new AddressEventArgs(this.Tag));
                }
            }
        }

2.主页部分

 void Create_Click(object sender, RoutedEventArgs e)
{
 SilverlightControl auc = new SilverlightControl();
            auc.Tag = "1";
            auc.Closed += new SilverlightControl.AddressEventHandler(auc_Closed);
            MasterContainer.Children.Add(auc);
}
void auc_Closed(object o,SilverlightControl.AddressEventArgs e)
{
//Code用户控件关闭后的操作
}
