我想为datagridviewcolumncollection
创建一个新属性 我创建了一个继承datagridviewcolumncollection
的类

Hai

I want to create a new property for datagridviewcolumncollection
I created a class which inherits datagridviewcolumncollection

Public Class NewDataCol Inherits datagridviewcolumncollection

并在此处添加了一些新属性.
之后，创建了一个继承Datagridview
的新类

and added some New property here.
after that created a new class which inherits Datagridview

Public class IGrid inherits Datagridview

我在这里使用此代码.

Here I use this code.

Private ColCollection As NewDataCol

  
    Public Overloads Property columns() As NewDataCol
        Get
            Return ColCollection
        End Get
        Set(ByVal value As NewDataCol)
            ColCollection = value
        End Set
    End Property

当我将Igrid添加到表单时，看不到任何新属性.
请告诉我怎么做.

谢谢

When i add Igrid to a form I can''t see any new property.
Please tell me how to do it.

Thanks

推荐答案

^ ]-在这里您需要开始.最后一个实验(实验编号7)是关于继承和覆盖的.第二个是: Visual Basic中的面向对象编程 [ ^ ].仔细阅读.

Introducing the Visual Studio .NET Lab Series[^] - here you need to start. The last lab (lab no. 7) is about Inheritance and Override. The second one is: Object-Oriented Programming in Visual Basic[^]. Read it carefully.
