Question

I have a bitmap loaded onto a winform via an imagebox. When I want to update the image I try as such:

imagebox.image = null;
draw();  //implements the drawing of the bitmap and assigns to the imagebox/winform

However, this will only work if I hide and then show the form again? How can I get around this?

EDIT: Problem resolved.

Answer 1

Make the image property setter smarter. For example:

private Image mImage;

public Image Image {
    get { return mImage; }
    set { 
        mImage = value;
        Invalidate();
    }
}

Now the visible image refreshes automatically.
