Custom property won't save when changed in property window

Question

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.

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;
  }
}
