public partial class Employee {  
    public class EmployeeMD {  
        [Display(Name = "Last Name", Order = -9,   
            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 GetAutoGenerateFilter 方法。

设置此属性将替代指定哪些列作为筛选器包含的默认行为。
