LESSON 2 Creating Controls

2. Type the bold text in the following code so the event handler looks like this:

// Create the new customer.

private void okButton_Click(object sender, EventArgs e)

{

resultLabel.Text = “New User Created”;

resultLabel.BackColor = Color.LightGreen;

resultLabel.Visible = true;

}

Add code behind the Cancel button to display the result label with a hot pink background



and the text “Operation Canceled.”

1. Double-click the Cancel button to create an event handler for its Click event.

2. Type the bold text in the following code so the event handler looks like this:

// Don’t create the new customer.

private void cancelButton_Click(object sender, EventArgs e)

{

resultLabel.Text = “Operation Canceled”;

resultLabel.BackColor = Color.HotPink;

resultLabel.Visible = true;

}

Now run the code and experiment with the program. Notice what happens when you press the [Enter]

and [Esc] keys while focus is in a

TextBox. See what happens if focus is on one of the buttons.
