I am new to C# and Winforms and try to make a moving panel. It should move right until the end of my window and then back left. It should bounce from side to side. But the only

Answer 1

Depending on what you're using:

1. Windows Forms
2. WPF

Create a Timer and subscribe to the Tick event. Also, you should create new int property Step.

1. Windows Forms:

System.Windows.Forms.Timer t = new System.Windows.Forms.Timer();
int Step;

Form1 () 
{
     InitializeComponent()
    ....
     t.Interval = 15000; // specify interval time as you want
     t.Tick += new EventHandler(timer_Tick); 
     t.Start();

     this.Step = 2; 
}

And in ticks event handler put your logic, without while

void timer_Tick(object sender, EventArgs e)
{
        if (pnlBox.Location.X >= 316)
        {
            Step = -2;
        }
        if (pnlBox.Location.X <= 0) 
        {
            Step = 2;
        }

        pnlBox.Location = new Point(
        pnlBox.Location.X + Step , pnlBox.Location.Y);
        string BoxLocationString = pnlBox.Location.ToString();
        lblXY.Text = BoxLocationString;
}

So your box will move on one step per one timer tick.

1. WPF:

As System.Windows.Forms.Timer is not available, you may use System.Windows.Threading.DispatcherTimer:

using System.Windows.Threading;

DispatcherTimer t = new DispatcherTimer();
t.Interval = new TimeSpan(0, 0, 15); // hours, minutes, seconds (there are more constructors)
t.Tick += Timer_Tick;
t.Start();
