C# Windows form application.
I'm stuck on how to mark the check boxes 1 to 5 in first and 6 to 10 in economy, When I select one of the radio buttons and hit reserve.
For example I select economy radio button, click reserve, the checkbox 1 should be greyed and disabled so it can't be automatically selected, and so on until all selections are made, and it returns a message airline full. I think my code may need to reworked abit, it didn't run well last time for me.
You will need to have two radio buttons to select First Class or Economy. On load, make radio button Economy selected (default). You will use only one button Reserve that should be disabled after all seats are reserved. What is new here is how seats are represented: you have to use checkboxes. At start, no checkboxes are selected. After each click on the Reserve button a correstponding cheackbox should be selected and disabled. You must have these methods implemented in a class Reserver that is separate from your Form: public bool IsFirstClassAvailable() public bool IsEconomyClassAvailable() public int ReserveFirstClassAnySeat() public int ReserveEconomyClassAnySeat() public bool[] GetAllSeats() public bool[] GetFirstClassSeats() public bool[] GetEconomyClassSeats() public void DisplayAllSeats() //this may be in your Form
