Create WPF Control Template programmaticaly with C# code

Question

 Hello,

I'm trying to create a style for a button, especially to change the IsMouseOver style (it must be overrided through a control template). I'm trying this code (I have to use c#, no xaml), but the button is only turning to yellow, IsMouseOver is not doing anything. Am I missing something ?

Here is the code :

private void CreateElement(int i)
{

UIElementOut[i] = new Button();

var uiElement = (Button)UIElementOut[i];

uiElement.Width = 100;

uiElement.Height = 100;

uiElement.VerticalAlignment = VerticalAlignment.Center;

uiElement.HorizontalAlignment = HorizontalAlignment.Center;

uiElement.Content = TextIn[i];

uiElement.FontFamily = new FontFamily(FFontInput[i]);

uiElement.FontSize = Convert.ToDouble(FontSizeIn[i]);

Style MyButtonStyle = new Style();

ControlTemplate templateButton = new ControlTemplate(typeof(Button));

FrameworkElementFactory elemFactory = new FrameworkElementFactory(typeof(Button));

elemFactory.Name = "myButton";

elemFactory.SetValue(Button.BackgroundProperty, Brushes.Yellow);

templateButton.VisualTree = elemFactory;

elemFactory.AppendChild(new FrameworkElementFactory(typeof(ContentPresenter)));

Trigger templateTrigger = new Trigger { Property = Button.IsPressedProperty, Value = true };

templateTrigger.Setters.Add(new Setter { Property = Button.ForegroundProperty, Value = Brushes.Violet });

templateTrigger.Setters.Add(new Setter { Property = Button.BackgroundProperty, Value = Brushes.Red });

templateButton.Triggers.Add(templateTrigger);

Setter setter = new Setter { TargetName = "myButton", Property = Button.TemplateProperty, Value = templateButton };

MyButtonStyle.Setters.Add(setter);

uiElement.Style = MyButtonStyle;

uiElement.Template = templateButton;

}

 

Thank you
