在属性窗口自定义属性不会改变的时候保存 [英] Custom property won't save when changed in property window

问题描述

我已经为DataGridView中自定义列，原因是我想要的属性（类型）添加到列。
我右键单击在DataGridView并选择编辑列...。然后，当我选择这是我的自定义字段类型，我能够编辑属性，但如果我类C确定修改完成后，然后进入编辑列...再次，我分配给我的财产值的列。走了

I've created a custom column for DataGridView, and the reason is that I want to add a property (type) to a column. I right click the DataGridView and select "Edit columns...". Then when I select the column that is my custom column type I'm able to edit the property, but if I clike "OK" after editing and then go to "Edit columns..." again the value that I assigned to my property is gone.

下面是我的代码：

public class CustomColumn : DataGridViewColumn
{
    [DisplayName("Type")]
    [Category("Custom Property")]
    public String type { get; set; }

    public CustomColumn()
        : base(new DataGridViewTextBoxCell())
    {
    }
}

和属性窗口的图像：

谁能告诉我，我做错了什么，或我需要补充，这样当我改变在属性窗口中的值，该值是分配给属性？

Can someone tell me what I'm doing wrong, or what I need to add so that when I change the value in the property window, that value is assigned to the property?

推荐答案

我认为你需要重写克隆（）方法，以便该工作：

I think you need to override the Clone() method in order for that to work:

public class CustomColumn : DataGridViewColumn {

  public CustomColumn()
    : base(new DataGridViewTextBoxCell()) {
  }

  [DisplayName("Type")]
  [Category("Custom Property")]
  public String type { get; set; }

  public override object Clone() {
    CustomColumn copy = base.Clone() as CustomColumn;
    copy.type = type;
    return copy;
  }
}
