在silverlight中实现对控件的deepcopy

使用XamlReader.Load(string)方法实现

步骤：

 
Xamlreader.load的用法:
1，在界面中拖拽自定义控件，设置布局和位置；
2，拷贝自定义控件代码，放入另外的xml文件中，在标记头加上命名空间和程序集声明，删除不必要的属性。这里要注意
 xmlns=\"http://schemas.microsoft.com/winfx/2006/xaml/presentation\"
 xmlns:x=\"http://schemas.microsoft.com/winfx/2006/xaml\" 
一定要有
3，使用xamlreader.load加载

public static FillSymbol loadfillsymbol()
        {
            string strxaml = "<symbol:FillSymbol xmlns=\"http://schemas.microsoft.com/winfx/2006/xaml/presentation\"  xmlns:arcsample=\"clr-namespace:arcgissampleApp.MAP;assembly=arcgissampleApp\" xmlns:x=\"http://schemas.microsoft.com/winfx/2006/xaml\" xmlns:symbol=\"clr-namespace:ESRI.ArcGIS.Client.Symbols;assembly=ESRI.ArcGIS.Client\" Fill=\"Red\" BorderThickness=\"2\">" +
                "<symbol:FillSymbol.ControlTemplate>"+
                    "<ControlTemplate>"+
                        "<Grid x:Name=\"RootElement\">"+
                            "<Grid.RowDefinitions>"+
                                "<RowDefinition Height=\"100\"/>"+
                                "<RowDefinition/>"+
                            "</Grid.RowDefinitions>"+
                            "<Grid.ColumnDefinitions>"+
                                "<ColumnDefinition Width=\"100\"/>"+
                                "<ColumnDefinition/>"+
                            "</Grid.ColumnDefinitions>"+
                            "<Path Grid.RowSpan=\"2\" Grid.ColumnSpan=\"2\" x:Name=\"Element\" Fill=\"{Binding Attributes[COLOR]}\" Stroke=\"Red\" StrokeThickness=\"1\" />"+
                            "<TextBlock Grid.RowSpan=\"2\" Grid.ColumnSpan=\"2\" Text=\"{Binding Attributes[NAME]}\" FontSize=\"20\" Foreground=\"Black\" HorizontalAlignment=\"Center\" VerticalAlignment=\"Center\">"+
                            "</TextBlock>"+
                            "<arcsample:SilverlightControl2 Grid.RowSpan=\"2\" Grid.ColumnSpan=\"2\" Margin=\"-100,-50,0,0\"  Grid.Row=\"0\" Grid.Column=\"0\" x:Name=\"sc2\" SelectedGroupM=\"{Binding Attributes[GGG]}\" HorizontalAlignment=\"Center\" VerticalAlignment=\"Center\"/>" +
                        "</Grid>"+
                    "</ControlTemplate>"+
                "</symbol:FillSymbol.ControlTemplate></symbol:FillSymbol>";
            FillSymbol symbol = XamlReader.Load(strxaml) as FillSymbol;
            return symbol;
        }
