    IItemsSource Interface
    In This Topic

    Provides an interface that is implemented by classes when a scenario calls for use of a collection of values represented by a ComboBox for a given property.

    Syntax
    'Declaration
 
Public Interface IItemsSource 
    'Usage
 
Dim instance As IItemsSource
    public interface IItemsSource
    Remarks

    You must decorate your property with ItemsSourceAttribute.

    Example
    First, create a class that implements IItemsSource.
    public class FontSizeItemsSource : IItemsSource
{
    public ItemCollection GetValues()
    {
        ItemCollection sizes = new ItemCollection();
        sizes.Add(5.0, "Five");
        sizes.Add(5.5);
        sizes.Add(6.0, "Six");
        sizes.Add(6.5);
        sizes.Add(7.0, "Seven");
        sizes.Add(7.5);
        sizes.Add(8.0, "Eight");
        sizes.Add(8.5);
        sizes.Add(9.0, "Nine");
        sizes.Add(9.5);
        sizes.Add(10.0);
        sizes.Add(12.0, "Twelve");
        sizes.Add(14.0);
        sizes.Add(16.0);
        sizes.Add(18.0);
        sizes.Add(20.0);
        return sizes;
    }
}
    Then decorate the property with the ItemsSource attribute.
    public class Person
{
    [Category("Writing")]
    [DisplayName("Writing Font Size")]
    [Description("This property uses the DoubleUpDown as the default editor.")]
    [ItemsSource(typeof(FontSizeItemsSource))]
    public double WritingFontSize { get; set; }
}
