I need inherit events and properties. For example, I need to move a picture around a form. I have this code to move one picture but I need to create multiple images with the same behavior.

private void pictureBox_MouseDown(object sender, MouseEventArgs e)
{
    if (e.Button == MouseButtons.Left)
    {
         x = e.X;
         y = e.Y;
     }
 }

private void pictureBox_MouseMove(object sender, MouseEventArgs e)  
{
    if (e.Button == MouseButtons.Left)
    {
        pictureBox.Left += (e.X -x);
        pictureBox.Top += (e.Y - y);
    }
 }

• c#
• winforms
• inheritance
• picturebox

Create custom control:

public class MovablePictureBox : PictureBox
{
    private int x;
    private int y;

    protected override void OnMouseDown(MouseEventArgs e)
    {
        base.OnMouseDown(e);

        if (e.Button == MouseButtons.Left)
        {
            x = e.X;
            y = e.Y;
        }
    }

    protected override void OnMouseMove(MouseEventArgs e)
    {
        base.OnMouseMove(e);

        if (e.Button == MouseButtons.Left)
        {
            Left += (e.X - x);
            Top += (e.Y - y);
        }
    }
}

UPDATE: Instead of attaching a delegates, you should override inherited event functionality, as Microsoft recommends here. After creating this control just compile program and drag your MovablePictureBoxes from Toolbox to form. They all will be draggable (or movable, if you wish).

What you really want to do is have your multiple PictureBoxes share the same event handlers:

private void pictureBox_MouseMove(object sender, MouseEventArgs e)   
{ 
    if (e.Button == MouseButtons.Left) 
    { 
        // the "sender" of this event will be the picture box who fired this event
        PictureBox thisBox = sender as PictureBox;            

        thisBox.Left += (e.X -x); 
        thisBox.Top += (e.Y - y); 
    } 
 }

Each PictureBox you create on your form keep hooking them up to the same, already created, event. If you look at the above code you'll notice that it determines which PictureBox called it and affects just that picture box.
