Creating and Using EventLog in WindowService

First Drag and Drop EventLog component into Component design from ToolBox 


Event log (named : eventLog1) is added into you component class.


Create New Event Log in your window service Component class

 public EmployeeStatusService()
 {
     InitializeComponent();
     if (!System.Diagnostics.EventLog.SourceExists("MyLogInfo"))
     {
          System.Diagnostics.EventLog.CreateEventSource(
                    "MyLogInfo", "HirenLog");
     }
     eventLog1.Source = "SmartNetDeviceInfo";
     eventLog1.Log = "SmartNetLog";
 } 

Write Log entry on created log

 protected override void OnStart(string[] args)
 {
     eventLog1.WriteEntry("Service Started");
 }

Use Your Resource as a Storyboard in FrameWithinGrid_ContentRendered Event

  private void FrameWithinGrid_ContentRendered(object sender, EventArgs e)
  {  
     Storyboard sb = this.Resources["GrowOut"] as Storyboard;
     sb.Completed += new EventHandler(sb_Completed);
     sb.Begin(FrameWithinGrid);
  }
  void sb_Completed(object sender, EventArgs e)
  {
     Storyboard sb = this.Resources["GrowIn"] as Storyboard;          
     sb.Begin(FrameWithinGrid);
  } 

WPF Frame Navigation Animation : TranslateTransform and RotateTransform

RotateTransform

MainWindow.xaml

<Frame Name="FrameWithinGrid"
               ContentRendered="FrameWithinGrid_ContentRendered"             
               Source="Home.xaml">
            <Frame.RenderTransform>
              <RotateTransform Angle="0"
                               CenterX="425"
                               CenterY="300" />

            </Frame.RenderTransform>

</Frame>

MainWindow.xaml.cs

 private void FrameWithinGrid_ContentRendered(object sender, EventArgs e)
 {
    Storyboard storyboard = new Storyboard();
    DoubleAnimation rotateAnimation = new DoubleAnimation();
    rotateAnimation.Duration = TimeSpan.FromMilliseconds(1000);
    rotateAnimation.From = 0;
    rotateAnimation.To = 180;        
    storyboard.Children.Add(rotateAnimation);
    Storyboard.SetTargetProperty(rotateAnimation,

          new PropertyPath("RenderTransform.Angle"));
    Storyboard.SetTarget(rotateAnimation, FrameWithinGrid);
    storyboard.Begin(); 
 }

TranslateTransform

MainWindow.xaml

<Frame Name="FrameWithinGrid"
               ContentRendered="FrameWithinGrid_ContentRendered"             
               Source="Home.xaml">
            <Frame.RenderTransform>
                <TranslateTransform X="0"
                                    Y="0" />

            </Frame.RenderTransform>

</Frame>

MainWindow.xaml.cs

 private void FrameWithinGrid_ContentRendered(object sender, EventArgs e)
 {
    Storyboard storyboard = new Storyboard();
    DoubleAnimation transAnimation = new DoubleAnimation();
    transAnimation.Duration = TimeSpan.FromMilliseconds(500);
    transAnimation.From = 0;
    transAnimation.To = 800;
    storyboard.Children.Add(transAnimation);
    Storyboard.SetTargetProperty(transAnimation, new PropertyPath("RenderTransform.X"));
    //Storyboard.SetTargetProperty(transAnimation, new PropertyPath("RenderTransform.Y"));
    Storyboard.SetTarget(transAnimation, FrameWithinGrid);
    storyboard.Completed += new EventHandler(storyboard_Completed);
    storyboard.Begin();
 }

 void storyboard_Completed(object sender, EventArgs e)
 {
    Storyboard storyboard = new Storyboard();
    DoubleAnimation growAnimation = new DoubleAnimation();
    growAnimation.Duration = TimeSpan.FromMilliseconds(500);
    growAnimation.From = -800;
    growAnimation.To = 0;
    storyboard.Children.Add(growAnimation);

    Storyboard.SetTargetProperty(growAnimation, new PropertyPath("RenderTransform.X"));
    //Storyboard.SetTargetProperty(growAnimation, new PropertyPath("RenderTransform.Y"));
    Storyboard.SetTarget(growAnimation, FrameWithinGrid);        
    storyboard.Begin();
 } 

WPF : Handling Event on View From ViewModel

1. First Create Event Handler in ViewModel 

LoginViewModel

   public event EventHandler LoginCompleted = delegate { };
   public void OnLoginCompleted()
   {
        LoginCompleted(this, new EventArgs());
   }

2. Handle ViewModel Event in View


LoginView.Xaml.cs

public LoginView()

{

   this.DataContext = new LoginViewModel(); 

   (this.DataContext as LoginViewModel).LoginCompleted += 

              new EventHandler(LoginViewModel_LoginCompleted); 

}

void LoginViewModel_LoginCompleted(object sender, EventArgs e)
{
   //your Coode goes here         
}
