Hi,

I have the following code below from a custom component, although my issue is that when I scroll away from the rectangle and then back on the control does not refresh so the rectangle keeps getting larger. I have to force a refresh by switching to a different application then back. How can I sort this?

Thanks,
Uni
public partial class MyCustomControl:ScrollableControl {
 
	//Constructor.
	public MyCustomControl() {
		InitializeComponent();
		this.SetStyle(ControlStyles.OptimizedDoubleBuffer|ControlStyles.UserPaint|ControlStyles.AllPaintingInWmPaint, true);
		this.AutoScroll=true;
		this.AutoScrollMinSize=new Size(2000, 2000);
		this.Paint+=new PaintEventHandler(MyCustomControl_Paint);
	}
 
	//The paint method.
	private void MyCustomControl_Paint(object sender, PaintEventArgs e) {
		e.Graphics.FillRectangle(Brushes.Azure, 0, 0, 20, 50);
	}
 
}
