Question

I MADE A PROGRAM IN WHICH I DIVIDED THE PROGRAM INTO 3PARTS.

1.BUSINESS LOGIC

2.PRESENTATION LOGIC

3.PROGRAM.CS

 

bt1 = new Button();

bt1.Text = "OK";

bt1.Location = new Point(50, 90);

.......................bt1.Click += bt1_Click;........................

bt2 = new Button();

bt2.Text = "CANCEL";

bt2.Location = new Point(140, 90);

...................bt2.Click += bt2_Click;...................

 THIS BUTTON bt1.click and bt2.click function

void bt2_Click(object sender, EventArgs e)

{

Application.Exit();

}

void bt1_Click(object sender, EventArgs e)

{

Process.Start(tb1.Text);

}

}

}

this function should appear in business logic page but its coming in presentation logic page

WHAT TO DO????
