Click-hold and drag on the star map you'll see the problem, the tiled .png that comes into view doesnt' get refreshed and i don't know how to fix it.

code responsible:

private void panel1_MouseMove(object sender, MouseEventArgs e)

{

if (e.Button == MouseButtons.Left)

{

offsetX = e.X - prevScrollPoint.X;

offsetY = e.Y - prevScrollPoint.Y;

pointX = -(panel1.AutoScrollPosition.X);

pointY = -(panel1.AutoScrollPosition.Y);

pointX += -offsetX;

pointY += -offsetY;

panel1.AutoScrollPosition = new Point(pointX, pointY);

prevScrollPoint = e.Location;

}

}

private void panel1_MouseDown(object sender, MouseEventArgs e)

{

if (e.Button == MouseButtons.Left)

{

prevScrollPoint = e.Location;

panel1.Refresh();

}

}

private void panel1_MouseUp(object sender, MouseEventArgs e)

{

if (e.Button == MouseButtons.Left)

{

panel1.AutoScrollPosition = new Point(pointX, pointY);

}

}


Currently i'm researcing on how to force a paint through native function PostMessage(i think). Any help appreciated.
