Question

有人知道如何将新的数据成员添加到checkboxboxlist的子类吗？

我尝试创建自己的窗口小部件，并试图让datagridview表现出我想要的样子。

后者运气不好，而前者我可能永远都做不完。

这是一个可绑定的复选框，我正尝试对其进行修改以适合我的需求。

namespace WinformsTest.Controls
{

    [ToolboxBitmap(typeof(CheckedListBox))]
    public class BindableCheckboxList : CheckedListBox
    {
        public BindableCheckboxList()
        {
            this.CheckOnClick = true;


        }

            {
                return base.DisplayMember;
            }
            set
            {
                base.DisplayMember = value;

        public new string ValueMember

            {
                return base.ValueMember;
            }
            set
            {
                base.ValueMember = value;

            }
        }


        [DefaultValue("")]
        [AttributeProvider(typeof(IListSource))]
        [RefreshProperties(RefreshProperties.All)]
        [Browsable(true)]
        [Category("Data")]
        public new object DataSource
        {
            get
            {
                return base.DataSource;
            }
            set
            {
                base.DataSource = value;
            }
        }
    }
}

请注意，我正在尝试添加CheckedMember

如果数据源有效且可绑定，我希望复选框列表将复选框更新为checkedMember。

如何将新的数据成员添加到自定义复选框列表中？
