Switching Assets

The following code can be used to set the AssetInstance of a screen and navigate to that screen. NOTE: this can be accomplished without scripting by using the NavigateSource property to navigate to a a different screen. The asset context of the current control is used when navigating to the screen.

Copy

public void OnClick(object sender, EventArgs eventArgs)
{
    // assuming that the sender base control has an "AssetInstance" property
    PropertyAssetInstance assetInstance = ControlBase.GetProperty<PropertyAssetInstance>(sender, "AssetInstance");

    //// in case the asset instance is actually set on a parent control
    //PropertyAssetInstance assetInstance = GetAssetInstance(sender as ControlBase);

    if (assetInstance != null)
    {
        string screenName = "Screen2";
        ControlScreen screen = Application.Screens[screenName] as ControlScreen;
        screen.AssetInstance = assetInstance;
        Application.CurrentScreen = screen;
    }
}

private PropertyAssetInstance GetAssetInstance(ControlBase control)
{
    if (control == null)
        return null;

    if (ControlBase.HasProperty(control, "AssetInstance"))
    {
        PropertyAssetInstance assetInstance = ControlBase.GetProperty<PropertyAssetInstance>(control, "AssetInstance");
        if (assetInstance != null)
            return assetInstance;
    }

    return GetAssetInstance(control.Parent as ControlBase);
}
