    ItemsSourceAttribute Class
    In This Topic
    Represents an attribute that is set on a property to identify the IItemsSource-derived class that will be used.
    Syntax
    'Declaration
     
    <AttributeUsageAttribute(AttributeTargets.All, 
       Inherited=True, 
       AllowMultiple=False)>
    Public Class ItemsSourceAttribute 
       Inherits System.Attribute
    'Usage
     
    Dim instance As ItemsSourceAttribute
    [AttributeUsage(AttributeTargets.All, 
       Inherited=true, 
       AllowMultiple=false)]
    public class ItemsSourceAttribute : System.Attribute 
    Remarks
    Use this attribute on a property when a scenario calls for use of a collection of values represented by a ComboBox for a given property.
    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; }
    }
