Hi, I am making a simple 2D map maker for games. Simply the user clicks on a button that will show a openfiledialog. The user chooses a file and is loaded in a PictureBox. Then if the user wants to add it to the game world(panel) he/she clicks on the add button and the panel will load the picture. What I am having trouble with is being able to drag and drop the image within that panel. I will appreciate your help.

Hello,

I think this can help:

C#

private bool isPictureReadyToDrag;
private void SetPosition()
{
     MyPictureBox.Location = new Point(MousePosition.X - this.Left - MyPictureBox.Width / 2, MousePosition.Y - this.Top - MyPictureBox.Height);
}

private void MyPictureBox_MouseMove(object sender, MouseEventArgs e)
{
     if (isPictureReadyToDrag)
         SetPosition();
}

private void MyPictureBox_MouseUp(object sender, MouseEventArgs e)
{
     isPictureReadyToDrag = false;
}

private void MyPictureBox_MouseDown(object sender, MouseEventArgs e)
{
     isPictureReadyToDrag = true;
     SetPosition();
}
