Enumeration at Runtime

Question

Hi people.
I've faced some problems through working with the PropertyGrid control.
Suppose that I have an object of a defined class with some defined properties. One of these properties is defined like this:

C#

public enum Intervals
{
  Free,
  Used,
  New
}

private Intervals _int;
public Intervals MyList
{
    get { return _int; }
    set { _int = value; }
}

When I assign an object of this class with a PropertyGrid control as "selectedobject" attribute, I can see "Free", "Used" and "New" items in a combobox in the PropertyGrid control, as you know.
But Problem is here:
How could I add (or remove) items to these values at runtime?
or
How could I add (or remove) values to an enumeration at runtime?

Make me happy, please.

Instead of a List, I'd use a Dictionary:

C#

Dictionary<string, int> enumerator = new Dictionary<string, int>();

enumerator.Add("enum1", 1);

There are many types of collections you can use. Your best bet is to google "c# collections" and pick the one that actually fits your requirements.

Solution 3

John's answer to use a Dictionary<> will work for you at the class level, but it will not automatically work as you expect with the property grid. So to add/edit/remove items at runtime from the property grid, you'd need to write some custom UI code using the UI extension features available for the property grid.
