private const int CS_DROPSHADOW = 0x00020000;
protected override CreateParams CreateParams
{
    get
    {
        // add the drop shadow flag for automatically drawing
        // a drop shadow around the form
        CreateParams cp = base.CreateParams;
        cp.ClassStyle |= CS_DROPSHADOW;
        return cp;
    }
}

this code used for shadowing effect to Window Form, but i want this effect to controls which are all present in the Form...
