以编程方式隐藏PropertyGrid中的字段 [英] Programmatically Hide Field in PropertyGrid

问题描述

使用

<System.ComponentModel.TypeConverter(GetType(System.ComponentModel.ExpandableObjectConverter))> _

在一个由数字组成的类（它是另一个类的属性）的声明上属性。

on the declaration of a class (which is a property of another class) that consists of a number properties.

我只用...加载此类的实例...

I load an instance of this class with simply ...

PropertyGrid1.SelectedObject = oColumn

很显然，我不想手动在代码中构建propertygrid ，我知道该怎么做。

Obviously I don't want to manually build the propertygrid in code, I know how to do that.

但这是问题所在。根据属性的值，某些其他属性应该不可见，就好像我使用

But here's the problem. Depending on the value of a property, certain other properties should not be visible, as though I'd used the

<System.ComponentModel.Browsable(False)> _

属性声明中的属性。

是否可以通过编程方式执行此操作，而无需手动处理属性网格的所有构建>

Is there anyway to do this programmatically, without having to handle all the building of the property grid manually>

推荐答案

希望然后找到gridItem.Hide（），答案是否定的。在MS PropertyGrid中实现此目标的唯一方法是通过TypeConverter或自定义类型描述符（实现ICustomTypeDescriptor）的GetProperties方法动态发布属性。我会首先尝试使用TypeConverter（特别是如果您要检查的属性值处于同一级别），那么要做的编码就更少了。

if you were hoping for a gridItem.Hide() then, the answer is no. The only way to achieve that in the MS PropertyGrid is to dynamically publish your properties through the GetProperties method of a TypeConverter or custom type descriptor (that implements ICustomTypeDescriptor). I would try first with the TypeConverter (expecially if the property values you want to check are at the same level), there is less coding to do.
