C# programmatically form to image

there are two forms in my program, Form A and Form B.

There is a button in Form A which can take a screen shot of Form B(without start Form B).

However, the components of Form B are created in Form_Load function.

I use the below code to take a screen shot of Form B but it only generate a empty Form B image without any component of its.

Bitmap b = new Bitmap(1280, 720);
formB.ManualLoad();
formB.DrawToBitmap(b, new Rectangle(0, 0, 1280, 720));
b.Save("D:\\Test.bmp");

The Manuaload() function is in below.

public void ManualLoad()
{
    formB_Load(null, null);
    formB_Resize(null, null);
    Invalidate();
}

How can I fix the problem?

I think

formB_Load(null, null); and formB_Resize(null, null);

ints even hanler load and resize event's

next code will be to work 

Bitmap b = new Bitmap(1280, 720);
var form = new formB();
form.Visible = false;
form.Show();
form.DrawToBitmap(b, new Rectangle(0, 0, 1280, 720));
form.Close();
b.Save("D:\\Test.bmp");
