本文提供了Checkbox与CheckedListBox、DataGridViewCheckBoxColumn等的联动关系

1、CheckboxAssociateFactroy.Create创建联动关系实例

     /// <summary>

     /// Checkbox与其他集合之间进行关联

     /// </summary>

     public class CheckboxAssociateFactroy

     {

         public static CheckboxAssociation Create(Control checkBoxSideObj, object listSideObj)

         {

             ICheckboxSide checkBoxSide = null;

             IListSide listSide = null;

             var checkBox = checkBoxSideObj as CheckBox;

             if (checkBox != null)

                 checkBoxSide = new CheckBoxSide(checkBox);

             var checkBoxX = checkBoxSideObj as CheckBoxX;

             if (checkBoxX != null)

                 checkBoxSide = new CheckBoxXSide(checkBoxX);

             var checkBoxColumn = listSideObj as DataGridViewCheckBoxColumn;

             if (checkBoxColumn != null)

                 listSide = new DataGridViewCheckBoxColumnSide(checkBoxColumn);

             var checkBoxXColumn = listSideObj as DataGridViewCheckBoxXColumn;

             if (checkBoxXColumn != null)

                 listSide = new DataGridViewCheckBoxXColumnSide(checkBoxXColumn);

             var checkedListBox = listSideObj as CheckedListBox;

             if (checkedListBox != null)

                 listSide = new CheckedListBoxSide(checkedListBox);

             var listBoxAdv = listSideObj as ListBoxAdv;

             if (listBoxAdv != null)

                 listSide = new ListBoxAdvSide(listBoxAdv);

             if (checkBoxSide == null)

                 throw new ArgumentException($"Can not get an {nameof(ICheckboxSide)} from {nameof(checkBoxSideObj)}");

             if (listSide == null)

                 throw new ArgumentException($"Can not get an {nameof(IListSide)} from {nameof(listSideObj)}");

             return new CheckboxAssociation(checkBoxSide, listSide);

         }

     }

2、Checkbox侧的抽取的接口

     /// <summary>

     /// The association of list side, such as Checkbox, CheckboxX(DotNetBar), eg

     /// </summary>

     public interface ICheckboxSide : IDisposable

     {

         /// <summary>

         /// Get the Checked property value of Checkbox

         /// </summary>

         bool Checked { get; }

         /// <summary>

         /// Notify others that my check property changed.

         /// </summary>

         Action NotifyCheckedChanged { get; set; }

         /// <summary>

         /// Set the check property value of Checkbox

         /// </summary>

         /// <param name="checkState"></param>

         void UpdateCheckedProperty(CheckState checkState);

     }

3、集合列表如CheckedListBox/DataGridViewCheckBoxColumn等抽取的接口

     /// <summary>

     /// The association of list side, such as DataGridViewCheckBoxColumn, ListBox, eg

     /// </summary>

     public interface IListSide : IDisposable

     {

         /// <summary>

         /// Get the total of all items

         /// </summary>

         int ItemsTotal { get; }

         /// <summary>

         /// Get count of checked items

         /// </summary>

         int CheckedCount { get; }

         /// <summary>

         /// Notify others that same items check property changed.

         /// </summary>

         Action NotifyCheckedChanged { get; set; }

         /// <summary>

         /// Set the check property value of all items

         /// </summary>

         /// <param name="setChecked"></param>

         void UpdateCheckedProperty(bool setChecked);

     }

 }

4、联动关系类CheckboxAssociation，当使用Factory创建好联动关系的实例后，调用CheckboxAssociation.UpdateCheckboxSide()方法可以根据你代码设置好的CheckedListBox的勾选情况来更新Checkbox一侧，

调用UpdateListSide则可以根据Checkbox的勾选来全选或者全不选CheckedListBox控件中的数据

     /// <summary>

     /// The association between CheckboxSide and ListSide

     /// </summary>

     public class CheckboxAssociation : IDisposable

     {

         private ICheckboxSide _checkboxSide;

         private IListSide _listSide;

         /// <summary>

         /// Constructor

         /// </summary>

         /// <param name="checkboxSide">Represent Checkbox/CheckboxX control</param>

         /// <param name="listSide">Represent DataGridViewCheckBoxColumn</param>

         public CheckboxAssociation(ICheckboxSide checkboxSide, IListSide listSide)

         {

             _checkboxSide = checkboxSide;

             _checkboxSide.NotifyCheckedChanged = UpdateListSide;

             _listSide = listSide;

             _listSide.NotifyCheckedChanged = UpdateCheckboxSide;

             UpdateCheckboxSide();

         }

         /// <summary>

         /// Update Checkbox by list

         /// </summary>

         public void UpdateCheckboxSide()

         {

             CheckState checkState;

             if (_listSide.CheckedCount == _listSide.ItemsTotal && _listSide.CheckedCount != )

                 checkState = CheckState.Checked;

             else if (_listSide.CheckedCount < _listSide.ItemsTotal && _listSide.CheckedCount != )

                 checkState = CheckState.Indeterminate;

             else

                 checkState = CheckState.Unchecked;

             _checkboxSide.UpdateCheckedProperty(checkState);

         }

         /// <summary>

         /// Update List item Checked Property value by Checkbox

         /// </summary>

         public void UpdateListSide()

         {

             _listSide.UpdateCheckedProperty(_checkboxSide.Checked);

         }

         public void Dispose()

         {

             if (_checkboxSide != null)

             {

                 _checkboxSide.Dispose();

                 _checkboxSide = null;

             }

             if (_listSide != null)

             {

                 _listSide.Dispose();

                 _listSide = null;

             }

         }

     }

5、CheckBox对应的ICheckboxSide

             NotifyCheckedChanged?.Invoke();

         }

         private bool IsEventValid()

         {

             var notOk = _checkBox == null || _checkBox.Disposing || _checkBox.IsDisposed;

             return !notOk;

         }

         public void Dispose()

         {

             if (_checkBox != null)

             {

                 _checkBox.MouseClick -= _checkBox_MouseClick;

                 _checkBox = null;

             }

         }

         /// <summary>

         /// Get the Checked property value of Checkbox

                     continue;

             }

         }

     }

11、调用方法：窗体中存在chkPassAll（Checkbox）和chLBSystemTemp（CheckedListBox），

目的：使这两个控件联动，并且初始化为全选

             _chkAllSource = CheckboxAssociateFactroy.Create(chkPassAll, chLBSystemTemp);

             chkPassAll.Checked = true;

             _chkAllSource.UpdateListSide();

注意需要在窗体类内声明私有变量_chkAllSource
