Silverlight Methode über Javascript aurufen

[martin_ch]

Sali mitenand

Ich versuche gerade über Javascript eine SIlverlight Methode aufzurufen welche dann dynamisch Inhalte eines Panels leert und dann neue Elemente hinzufügen soll.

Die Funktion wird zwar aufgerufen allerding werden die Elemente nicht gelöscht - habe ich da was übersehen?

namespace SilverlightMultiTouch
{
[ScriptableType]
public partial class MainPage : UserControl
{
public StackPanel thePanel;
public MainPage()
{

thePanel = this.myPanel;
InitializeComponent();
HtmlPage.RegisterScriptableObject("test", this);
//HtmlPage.RegisterScriptableObject("test", this);


this.Loaded += (s, a) =>
{
//LoadImages();
//Initialize the items
System.Windows.Interactivity.Interaction.GetBehaviors(video).OfType<MultiTouchManipulationBehavior>().First().Move(new Point(300, 300), -20, 80);
System.Windows.Interactivity.Interaction.GetBehaviors(video).OfType<MultiTouchManipulationBehavior>().First().BringToFront();
System.Windows.Interactivity.Interaction.GetBehaviors(image1).OfType<MultiTouchManipulationBehavior>().First().Move(new Point(150, 250), 45, 100);
System.Windows.Interactivity.Interaction.GetBehaviors(image2).OfType<MultiTouchManipulationBehavior>().First().Move(new Point(400, 300), -45, 150);
System.Windows.Interactivity.Interaction.GetBehaviors(text1).OfType<MultiTouchManipulationBehavior>().First().Move(new Point(400, 300), -45, 150);


};
}

[ScriptableMember]
public void loadFromJavascript(){
System.Windows.Browser.HtmlPage.Window.Alert("Load From Java"); //funktioniert
LoadImages();
}


private void LoadImages()
{

thePanel.Children.Clear(); //geht nicht
myPanel.Children.Clear(); //geht auch nicht
System.Windows.Browser.HtmlPage.Window.Alert("Load From Java"); //funktioniert

}
}
}
