ASP.Net CSharp Exercises

Exercise 1

Create a C# ASP.NET WebForms Application

• Add a common MasterPage
• Display the current date and time in a label in yyyy-MM-dd hh:mm:ss format
• Refresh the time using a timer event every 5 seconds Note: Make use of UpdatePanels throughout the exercises to minimize full page refreshes

Exercise 2

Add a content page (rounding.aspx) to the MasterPage from the previous exercise

• Add a text-box for the user to enter a date time string
• Add a Test button
  • Clicking on the submit will do client-side validation to ensure the input is in yyyy-MM-dd h:mm format
  • If the validation fails, show an alert and halt processing further
  • If the validation passes, round the input to the nearest 15 minutes on the server and display inside another label
• The rounding logic should be in a business logic class
  • The method should take in a DateTime round it and return it as a DateTime
  • Write a series of unit-tests in a separate class to test the math:

Testing Examples

1. 2015-05-18 7:01 -> 2015-05-18 7:00
2. 2015-05-18 7:07 -> 2015-05-18 7:00
3. 2015-05-18 7:08 -> 2015-05-18 7:15
4. 2015-05-18 7:15 -> 2015-05-18 7:15
5. 2015-05-18 7:22 -> 2015-05-18 7:15
6. 2015-05-18 7:23 -> 2015-05-18 7:30

Exercise 3

Add another content page (timestamp.aspx) to the MasterPage

• Add a Log Timestamp button
• Add a simple one column grid
• Clicking on the button will confirm with the user whether to log the Timestamp or not
  • If yes, add the current time from the MasterPage to the grid in yyyy-MM-dd hh:mm:ss format
  • If no, dont do anything Note: you dont need to persist the data

Exercise 4

Add a home page (default.aspx)

• Show link buttons for rounding.aspx and timestamp.aspx pages
• Clicking on the link button will navigate to each page
