What have you done so far? Where are you stuck?

I have
namespace DragnDrop
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
panel1.AllowDrop = true;
panel2.AllowDrop = true;

//panel1.DragEnter += panel_DragEnter;
//panel2.DragEnter += panel2_DragEnter;

//panel1.DragDrop += panel_DragDrop;
panel2.DragDrop += panel_DragDrop;
panel2.DragOver += panel2_DragOver;

button1.MouseDown += button1_MouseDown;
}

void button1_MouseDown(object sender, MouseEventArgs e)
{
button1.DoDragDrop(button1, DragDropEffects.Copy);
}

//void panel2_DragEnter(object sender, DragEventArgs e)
//{
// e.Effect = DragDropEffects.All;
//}

void panel_DragDrop(object sender, DragEventArgs e)
{
((Button)e.Data.GetData(typeof(Button))).Parent = (Panel)sender;
}

private void panel2_DragOver(object sender, DragEventArgs e)
{
e.Effect = DragDropEffects.Copy;
}
}
}

I try to get dublicate of button on DragOver

On drop event you need to create new button, like this: Button btn = new Button; then set its properties based on properties of copied button. That's all ;)

Word of advice: Code are much more readable if it is inside a code block. It would have been better to update your question to include the code.

I would suggest you to start here:

I think it's enough for start.
