What's the simplest way to bind a list of checkboxes to a list of checked values

Question

I have a list of AvailableItems that I want to display as a list of checkboxes, so that users can pick which items to generate, which are then stored in another lis

Answer 1

I honestly would create a list of objects containing both the string and a boolean indicating if it is checked.

With a little Linq you can generate your list of objects and bind it to itemSource instead of binding the list of strings.

It will be simpler in the end, especially if you actually need to update something if the user is allowed to check/uncheck the checkboxes.

in answer to the comment, my take on this because I'm not sure I understand what the actual problem would be: provided we have the full list (AvailableItems) and the list of selected items (ItemsToGenerate):

public class ItemEntry
{
  public string Name { get; set; }
  public bool IsSelected {get; set; }
}

...

_Items = from item in AvailableItems
            select new ItemEntry() { 
                    Name = item, 
                    IsSelected = ItemsToGenerate.contains(item)
                  }).ToList();

You can then bind your list like so, by exposing _Items as a property named Items:

You can at a later time select from _Items where IsSelected is true to get the selected items if you need to.

Also, if ItemsToGenerate can get big, you should create a HashSet of the values and use it in the query, that should make it faster if need be.
