Need help with my using a control box to display values

Mar 24 2012 6:56 AM
I am doing a calculator for figuring out the price of carpet per square yard. this is for a homework assignment.  the assignment is as follows:

Create a Windows application for purchasing carpet.Allow the length and width of a
room to be entered. Have a control that displays different prices of carpet. Include, for
example, prices such as $21.95 per square yard.After the users enter their room dimensions
and the price of the carpet, display the total cost to carpet the room. Include an
option to clear selections.

according to the instructions i need a control that displays the different prices of carpet.  now i have that figured as a control box.  I'm in college learning to become a programmer.  the problem is i can get everything to work in the window with the exception of getting the price to calculate into the equation. any help i can get to help me solve this would be appriciated.

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace CarpetCalc
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void Calculate_Click(object sender, EventArgs e)
{
double rmlength = 0;
double rmwidth = 0;
double pricePerYard = 0;
double totalCost = 0;


/* Calculating Price Per Yard
Formula Used: length * Width / 9 = sq yd
*/

rmlength = Convert.ToDouble(roomLength.Text);
rmwidth = Convert.ToDouble(roomWidth.Text);
pricePerYard = Decimal.Parse(PriceYd.SelectedItem.ToString());

totalCost = (rmlength * rmwidth) / 9;
TotalCstTxt.Text = totalCost.ToString("N2");

}

private void Reset_Click(object sender, EventArgs e)
{

// This is used to clear the box when you hit reset
roomLength.Clear();
roomWidth.Clear();
TotalCstTxt.Clear();

}

private void Form1_Load(object sender, EventArgs e)
{

}


}
}
