Hi Tanuj Kumar,
If you want to invoke Form_Paint event on button click event then you have to write code in such way:
public void draw(object sender, PaintEventArgs e)
        {
            try
            {
                using (LinearGradientBrush brush = new LinearGradientBrush(ClientRectangle, Color colr1, Color colr2, LinearGradientMode.Vertical))
                {
                    e.Graphics.FillRectangle(brush, ClientRectangle);
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
        }
private void btnApply_Click(object sender, EventArgs e)
        {
            Paint += draw;
            Invalidate();
        }

I hope it might be resolve your problem.
