使属性在DataGridView中可见，但不在PropertyGrid中？ [英] Make a property visible in DataGridView but NOT in PropertyGrid?

问题描述

假设我有一个需要在DataGridView中显示的属性，但是在PropertyGrid中显示的对象不是这样。我知道我可以使用 [Browsable（false）] ，但是会隐藏在这两个视图中。我也可以做一个 gridView.Columns [blah]。Visible = false; ，但这与我想要的相反，因为它隐藏在DataGridView中，但不是在PropertyGrid。有没有办法做相反的事情？ （没有创建一个全新的DataTable只是为了保存相同的数据减去一个字段，并重新绑定所有的东西 - 这真的是一个kludge的方式来做事情。）或者，我可以生活一个解决方案，添加一个列到DataGridView

解决方案

可以通过使用PropertyGrid的BrowsableAttributes属性来解决此问题。
首先，创建一个这样的新属性：

  public class PropertyGridBrowsableAttribute：Attribute 
 {
私人bool可浏览; 
 public PropertyGridBrowsableAttribute（bool browsable）{
 this.browsable = browsable; 
} 
} 
  

然后将此属性添加到您想要的所有属性将显示在您的PropertyGrid中：

  [DisplayName（First Name），Category（Names），PropertyGridBrowsable ）] 
 public string FirstName {
 get {return ...} 
 set {...} 
} 
  

然后设置BrowsableAttributes属性，如下所示：

  myPropertyGrid.BrowsableAttributes = new AttributeCollection（
 new Attribute [] {new PropertyGridBrowsableAttribute（true）}）; 
  

这将只显示属性网格中的属性属性，而DataGridView仍然可以只访问所有属性更多的编码工作。

我仍然会和Tergiver一起去打电话，因为Browsable属性的文档清楚地表明它仅用于属性窗口

Let's say I have a property which I want shown in a DataGridView, but not when the same object is shown in a PropertyGrid. I know I can use [Browsable(false)], but that hides it in both views. I can also do a gridView.Columns["blah"].Visible = false;, but this is the opposite of what I want, as it hides in the DataGridView but not in PropertyGrid. Is there some way to do the reverse? (Short of creating a whole new DataTable just to hold the same data minus one field, and rebinding everything to that instead - that's really a kludge way to do things.) Alternatively, I could live with a solution which adds a column to the DataGridView that is not present on the actual class.

解决方案

it is possible to solve this issue by using the BrowsableAttributes property of a PropertyGrid. First, create a new attribute like this:

public class PropertyGridBrowsableAttribute : Attribute
{
    private bool browsable;
    public PropertyGridBrowsableAttribute(bool browsable){
        this.browsable = browsable;
    }
}

Then add this attribute to all those properties which you want to be shown in your PropertyGrid:

[DisplayName("First Name"), Category("Names"), PropertyGridBrowsable(true)]
public string FirstName {
    get { return ... }
    set { ... }
}

Then set the BrowsableAttributes property like this:

myPropertyGrid.BrowsableAttributes = new AttributeCollection(
    new Attribute[] { new PropertyGridBrowsableAttribute(true) });

This will only show the attributed properties in your property grid and the DataGridView can still access all properties with only a little bit more coding effort.

I would still go with Tergiver and call this behaviour a bug, since the documentation of the Browsable attribute clearly states its use for property windows only.
