Getting Started

Start up Visual Studio and create a new ASP.NET Web Site named U:\Labs\nnLab1 where nn is your cs351 account number.
Edit the Default.aspx page by adding the h1 and h2 tags with your own account number and name.
Review the work done yesterday in Day 4 to help with the hand-coding of HTML and ASP.NET controls.

Start Up Values

Set the default interest rate to 7%
Set the default time period to 20 years, but provide time periods of 10, 15, and 20 years
Provide AccessKeys for the Web controls
- Alt-C for the Calculate Interest button, Alt-R for the Reset Button
- Other AccessKeys are indicated with underlines
Validate your code to XHTML 1.0 Transitional

Event Handler Methods

Add an event handler for the Calcuate Interest button to calculate the simple interest accrued based on the following formula:

calculatedInterest = loanAmount * interestRate * numberOfYears

Display the calculated interest underneath the fieldset as shown on the screen snapshot.

The Reset button should set all controls back to their default values and clear the calculated interest output (if any)

Notes

The Convert class methods can be used convert strings to numeric values. For example:

double loanAmount = Convert.ToDouble(LoanAmountTextBox.Text);

The String.Format method using format strings is the easiest way to produce the output. See String Formatting in C# for an explanation of the formatting specifiers.
