Remarks
NoteNote

This material discusses types and namespaces that are obsolete. For more information, see Deprecated Types in Windows Workflow Foundation 4.5.

This attribute should only be used as dependency property option. Attributes are ignored if declared on a .NET property.

The ValidationOptionAttribute is intended to be used on Meta-properties only. It will be ignored for instance properties. For more information, see Using Activity Properties for more details.

If the ValidationOptionAttribute is not specified, the behavior defaults to ValidationOptionOptional.

public sealed partial class Activity1: Activity
{
    public Activity1()
    {
    }

    public static DependencyProperty MyPropertyProperty = 
        DependencyProperty.Register(
            "MyProperty", 
            typeof(string), 
            typeof(Activity1),
            new PropertyMetadata(
                DependencyPropertyOptions.Metadata,
                new ValidationOptionAttribute(ValidationOption.Required)));

    [Browsable(true)]
    [DesignerSerializationVisibility(DesignerSerializationVisibility.Visible)]
    public string MyProperty
    {
        get
        {
            return ((string)(base.GetValue(Activity1.MyPropertyProperty)));
        }
        set
        {
            base.SetValue(Activity1.MyPropertyProperty, value);
        }
    }
}
