Before you can do this exercise, you'll need to download and unzip this file (if you have any problems doing this, click here for help).

You need a minimum screen resolution of about 700 pixels width to see our exercises. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.

Create a new website, and add the 4 files in the above folder into it.

Create a new web page called frmNew.aspx, which asks a user to type in a film name.  If the user leaves the text box blank, you should display an error like this:

ASP.NET 4.0 - Visual Basic exercise - Maintaining state (image 1)

Here we've left the film blank twice - we have one more go

Use a hidden literal to remember the number of attempts in view state (remember to initialise it to 0 on first page load).

If you fail to type something in more than 3 times, you should see an error like this:

ASP.NET 4.0 - Visual Basic exercise - Maintaining state (image 2)

Set the ENABLED property of the textbox and button in code to achieve this

If, on the other hand, you type in a film name, you should see it confirmed back to you:

ASP.NET 4.0 - Visual Basic exercise - Maintaining state (image 3)

Your font can be smaller - this uses the ImportantMessage class
