            Prompt = "Enter Last Name", Description="Emp Last Name")]
        public object LastName { get; set; }

        [Display(Name = "Manager", AutoGenerateFilter=false)]
        public object Employee1 { get; set; }
    }
}

<MetadataType(GetType(EmployeeMD))>  _
Public Class Employee

    Public Class EmployeeMD

        <Display(Name:="Last Name", Order:=-9, _
           Prompt:="Enter Last Name", Description:="Emp Last Name")>  _
        Public Property LastName As Object
        End Property

        <Display(Name:="Manager", AutoGenerateFilter:=false)>  _
        Public Property Employee1 As Object
        End Property
    End Class
End Class

注解

请勿使用此属性获取属性的值 AutoGenerateFilter 。 请改用该方法 GetAutoGenerateFilter 。

设置此属性将替代用于指定哪些列作为筛选器包含的默认行为。
