Create a master page that will be used as a template for every page within the web site. This master page will use a HTML table to layout the four main sections of the page: header, navigation, content area, and footer. You will then create a simple theme and skin file to alter the font for the label control that was placed on the page.

The display property for the ASP.NET validation controls have 3 settings: None, Static, and Dynamic. The results of setting the display property to None is self-explanatory. However, what is the difference between Static and Dynamic? The difference between the two can be seen when looking at the source in your browser after the page is loaded at run-time.
When the Display property is set to Dynamic, the CSS display attribute is set to none on the control. When the Display property is set to Static, the CSS visibility attribute is set to hidden and the display property is not used at all as shown in the browser output below:
Validation Control Display = Dynamic
<td style=”width: 491px; height: 16px”>
<span id=”RangeValidator1″
style=”display: inline-block; color: Red; width: 226px;
display: none;“>The age must be between 0 and 100 </span>
</td>
Validation Control Display = Static
<td style=”width: 491px; height: 16px”>
<span id=”Span1″
style=”display: inline-block; color: Red; width: 226px; visibility: hidden;“>
The age must be between 0 and 100 </span>
</td>
The default setting on the control for the Display property is Static. By setting this to Static the space for the error message is reserved. The advantages here is that the controls placed positionally to the right of the validation control will not be moved at run-time if the display message of the validation box appears.

In this lab you will build a simple form that demonstrates the usage of the ASP.NET validation controls. You will create a simple form that accepts a Name, Age, Email, and Phone Number for a person.
The requirements for the text boxes on this entry page are listed below:
| Requirement | Validation Control Needed |
| The Name field is required and cannot be blank | RequiredFieldValidator |
| The Age field must not allow numbers less than zero or greater than 100 | RangeValidator |
| The Email field must capture valid internet email addresses | RegularExpressionValidator |
| The Phone Number field must capture valid phone numbers | RegularExpressionValidator |
You will then configure the validators to properly meet the requirements above. At the end, you will implement the Validation Summary control to change the display of the validation errors.

In this lab you will experiment with various ways to handle runtime exceptions. You will create a simple web page that will divide two numbers. If a zero is used in the calculation, you will trap the error and display it on the web page. Also, you will enable an option for run-time page tracing.

In this exercise you will create an application similar to the currency converter created in Chapter 5 from your book. This application will convert U.S. dollars to various currencies using HTML server controls. The application will use application settings in the web.config file to make updates easier than recompiling and redeploying the entire application.

In this exercise, you will create a new web site using Visual Studio 2005. In addition, you will create a class that has member variables, accessors, and a method. Once this is created, you will create an instance of the class and call the method to display HTML product information on a web page.

In this exercise, you will create a new web site using Visual Studio 2005. In addition, you will add three controls to the default page and add code to calculate the square root of a number and display it on the page. You will then rerun the application with a breakpoint and observe the value of the text variables placed into the controls during runtime.
