3. Based on the specifications provided by Dr. Dinewell (listed in the scenario at the top of these lab instructions), write
the additional statement needed in the Else clause to calculate the BMR for men. Use the formula for women provided
in the function as a model.
Hint: You only need to replace the “‘TO DO:” line with the men’s BMR values.
4. Save your work so far.
STEP 4: Add Input Validation
1. Return to editing the CalNeeds.aspx Web form in Design View.
2. Drag a RequiredFieldValidator control from the Validation section of the Toolbox and place it on the form just to the
right of the txtHeight TextBox. Set its properties as follows to ensure that the user enters a value for height:
Property Setting
ControlToValidate txtHeight
Display Dynamic
ErrorMessage You must enter your height in inches.
3. Drag a RangeValidator control from the Validation section of the Toolbox and place it on the form to the right of the
RequiredFieldValidator you added in the previous action. (It’s OK if the validators wrap onto the next line in the editing
window display.) Set the RangeValidator’s properties as follows to ensure that the user enters a height value that is a
type Double (that is, a decimal number,) that is in the range of 48 to 84 inches:
Property Setting
ControlToValidate txtHeight
Display Dynamic
ErrorMessage Height must be a decimal number between 48 and 84 inches.
MaximumValue 84
MinimumValue 48
Type Double
Here is what part of your form should look like with both validation controls in place (what you see may vary depending
on the width of your editing window):
4. In a similar way, place a RequiredFieldValidator and a RangeValidator to the right of the txtWeight TextBox, and set
their properties to ensure that the user enters a value for weight, and that value is a type Double (decimal number) that
is between 50 pounds and 500 pounds. Compose your own reasonable error messages for these validators.
5. Place a RequiredFieldValidator and a RangeValidator to the right of the txtAge TextBox, and set their properties to
ensure that the user enters a value for age, and that value is a type Integer (whole number) that is between 18 and
120. Compose your own reasonable error messages for these validators.
6. Save your work.
