Question

Emma’s Custom Embroidery sells shirts with detailed embroidered images. Emma allows users to select the color for a shirt, but she allows only specific embroidery designs with each shirt color. Create a project named EmmasEmbroidery that allows a user to choose one of four shirt colors from a ListBox—white, black, red, or blue. When the user selects a shirt color, the program should display a second ListBox that contains the following embroidery design choices:

•   White shirt—peacock, palm tree, or rose

•   Black shirt—race car, star, or moon

•   Red shirt—palm tree or moon

•   Blue shirt—peacock or moon

After the user selects an embroidery design, the program should display a congratulatory message on a Label indicating that the choice is a good one, and the design ListBox also becomes invisible. If the user makes a new selection from the shirt color ListBox, the congratulatory message is invisible until the user selects a complementary design.

Hint: You can remove the entire contents of a ListBox using the Items.Clear() method, as in this.listBox1.Items.Clear();. (Farrell 670)

.

Explanation / Answer

As per the question a C# application is being created .It has basically winform application which is having the list boxes.

The project (EmmasEmbroidery) is having mainly 2 files one EmmasEmbroideryMainForm.cs and EmmasEmbroideryMainForm.Designer.cs.

Below is the code for the same.

private const string Red = "Red";
private const string Blue = "Blue";

public EmmasEmbroideryMainForm()
{
InitializeComponent();
this.listBoxDesignChoices.Visible = false;
this.labelMesage.Visible = false;
}

private void listBoxShirtColors_SelectedIndexChanged(object sender, EventArgs e)
{
this.labelMesage.Visible = false;
this.listBoxDesignChoices.Items.Clear();
string selectedItem = listBoxShirtColors.SelectedValue != null ?
listBoxShirtColors.SelectedValue.ToString():
string.Empty;
  
switch (selectedItem)
  
{
case White:
this.listBoxDesignChoices.Items.AddRange(new string[]{"Peacock", "Palm Tree", "Rose"});
break;

case Black:
this.listBoxDesignChoices.Items.AddRange(new string[] { "Race Car", "Star", "Moon" });

break;

case Blue:

}

this.listBoxDesignChoices.Visible = true;
}

private void listBoxDesignChoices_SelectedValueChanged(object sender, EventArgs e)
{

this.labelMesage.Text = string.Format("Congratution !!! you have selected [{0}] which is really good.",
selectedItem
