如何从desinger中编辑属性类？ [英] How do I edit class of property from the desinger ?

问题描述

我有这个类继承自ColumnHeader

I have this class Inherited from ColumnHeader

Public Class xcolumnheader

   Inherits ColumnHeader

   <Browsable(True), DesignerSerializationVisibility(DesignerSerializationVisibility.Content)>
   Public Property CP As New CollectionOfProperties

   Public Class CollectionOfProperties

       <Browsable(True)>
       Public Property Property1 As Boolean

       <Browsable(True)>
       Public Property Property2 As String

       <Browsable(True)>
       Public Property Property3 As Integer

   End Class

End Class

推荐答案

你只有将ExpandableObjectConverter作为TypeConverter添加到您的类：

You only have to add the ExpandableObjectConverter as TypeConverter to your class :

Imports System.ComponentModel

Public Class xColumnHeader
    Inherits ColumnHeader

    <DesignerSerializationVisibility(DesignerSerializationVisibility.Content)>
    Public Property CP As New CollectionOfProperties

    <TypeConverter(GetType(ExpandableObjectConverter))>
    Public Class CollectionOfProperties

        Public Property Property1 As Boolean

        Public Property Property2 As String

        Public Property Property3 As Integer

    End Class

End Class

补充：

您的属性 - 每个属性都不需要Browsable-Attribute通常总是'可浏览'。如果您希望属性不可浏览，则只需要此属性...

Additional :
You don't need the Browsable-Attribute at your Properties - each Property is normally allways 'browsable'. You only need this Attribute if you want that you Property is NOT browsable ...
