I'm m开发者_如何学Pythonaking a simple custom control and I would like to have a dropdownlist of defined custom properties and I'm perplexed as to why the code below fails to display the enum in the properties list of the combobox.

How do I display enum values in a Dropdownlist?

public partial class MyComboBox : ComboBox
{
    public enum Multipliers { B = 1, KB = 2, MB = 10, GB = 20, TB = 30 } { get; set; }
    public string SuperType { get; set; }
    public bool Global { get; set; }
}


You're not showing any code relating to how you're putting those enum values INTO the actual display list. You have to point the ComboBox at your enum as a DataSource (technically you have to point it at a call to Enum.GetValues(typeof(Multipliers))), or manually manipulate the Items collection, to get your values into the list.


Here's what you need to do:

foreach (var item in Enum.GetValues(typeof(Multipliers )))
        {
            ComboBox1.Items.Add(item);
        }


The enum is a type within MyComboBox, not a property.

You could create a property like this:

public partial class MyComboBox : ComboBox
{
    public enum Multipliers { B = 1, KB = 2, MB = 10, GB = 20, TB = 30 }
    public string SuperType { get; set; }
    public bool Global { get; set; }
    public Multipliers myMultiplierProperty {get; set;}
}

As to how those properties show up in the combo box depends a lot on the code that puts them in there. Since you haven't given us that, I can't help if the problem is in there.
