How to move form on screen programmatically with animated effect?

Question

How can I make my form go from location 0.0 to location 100.100 on the screen without user interaction, ie through programming, this movement needs to be animated, ie can not disappear from one point and go to another, need to look like it moved there.

Answer 1

I think the simplest way to do what you want is to use the library Winformanimation.

To install, simply use the following command: Package Manager Console:

Install-Package Winformanimation

Once done, just use the following code:

private void button1_Click(object sender, EventArgs e)
{
    new Animator2D(new Path2D(new Float2D(-100, -100), this.Location.ToFloat2D(), 500))
        .Play(this, Animator2D.KnownProperties.Location);
}

Where this is the Form current, but you can change to any element (other form, button, text, etc).

For more details, look at official documentation.

In the same question as the @Guillhermenascimento posted, has this example who can also help you.

If I understood you want an animated effect when the element is moved, I found this answer https://stackoverflow.com/a/6103677/1518921

Create/declare the following class:

using System;
using System.ComponentModel;
using System.Windows.Forms;
using System.Runtime.InteropServices;

public static class Util {
    public enum Effect { Roll, Slide, Center, Blend }

    public static void Animate(Control ctl, Effect effect, int msec, int angle) {
        int flags = effmap[(int)effect];
        if (ctl.Visible) { flags |= 0x10000; angle += 180; }
        else {
            if (ctl.TopLevelControl == ctl) flags |= 0x20000; 
            else if (effect == Effect.Blend) throw new ArgumentException();
        }
        flags |= dirmap[(angle % 360) / 45];
        bool ok = AnimateWindow(ctl.Handle, msec, flags);
        if (!ok) throw new Exception("Animation failed");
        ctl.Visible = !ctl.Visible;
    }

    private static int[] dirmap = { 1, 5, 4, 6, 2, 10, 8, 9 };
    private static int[] effmap = { 0, 0x40000, 0x10, 0x80000 };

    [DllImport("user32.dll")]
    private static extern bool AnimateWindow(IntPtr handle, int msec, int flags);
}

And to use it do something like:

private void button2_Click(object sender, EventArgs e) {
    Util.Animate(form1, Util.Effect.Slide, 150, 180);
}
