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

 1     /// <summary>
 2     /// Checkbox与其他集合之间进行关联
 3     /// </summary>
 4     public class CheckboxAssociateFactroy
 5     {
 6         public static CheckboxAssociation Create(Control checkBoxSideObj, object listSideObj)
 7         {
 8             ICheckboxSide checkBoxSide = null;
 9             IListSide listSide = null;
10 
11             var checkBox = checkBoxSideObj as CheckBox;
12             if (checkBox != null)
13                 checkBoxSide = new CheckBoxSide(checkBox);
14             var checkBoxX = checkBoxSideObj as CheckBoxX;
15             if (checkBoxX != null)
16                 checkBoxSide = new CheckBoxXSide(checkBoxX);
17 
18             var checkBoxColumn = listSideObj as DataGridViewCheckBoxColumn;
19             if (checkBoxColumn != null)
20                 listSide = new DataGridViewCheckBoxColumnSide(checkBoxColumn);
21 
22             var checkBoxXColumn = listSideObj as DataGridViewCheckBoxXColumn;
23             if (checkBoxXColumn != null)
24                 listSide = new DataGridViewCheckBoxXColumnSide(checkBoxXColumn);
25 
26             var checkedListBox = listSideObj as CheckedListBox;
27             if (checkedListBox != null)
28                 listSide = new CheckedListBoxSide(checkedListBox);
29 
30             var listBoxAdv = listSideObj as ListBoxAdv;
31             if (listBoxAdv != null)
32                 listSide = new ListBoxAdvSide(listBoxAdv);
33 
34             if (checkBoxSide == null)
35                 throw new ArgumentException($"Can not get an {nameof(ICheckboxSide)} from {nameof(checkBoxSideObj)}");
36             if (listSide == null)
37                 throw new ArgumentException($"Can not get an {nameof(IListSide)} from {nameof(listSideObj)}");
38 
39             return new CheckboxAssociation(checkBoxSide, listSide);
40         }
41     }

2、Checkbox侧的抽取的接口

 1     /// <summary>
 2     /// The association of list side, such as Checkbox, CheckboxX(DotNetBar), eg
 3     /// </summary>
 4     public interface ICheckboxSide : IDisposable
 5     {
 6         /// <summary>
 7         /// Get the Checked property value of Checkbox
 8         /// </summary>
 9         bool Checked { get; }
10 
11         /// <summary>
12         /// Notify others that my check property changed.
13         /// </summary>
14         Action NotifyCheckedChanged { get; set; }
15 
16         /// <summary>
17         /// Set the check property value of Checkbox
18         /// </summary>
19         /// <param name="checkState"></param>
20         void UpdateCheckedProperty(CheckState checkState);
21     }

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

 1     /// <summary>
 2     /// The association of list side, such as DataGridViewCheckBoxColumn, ListBox, eg
 3     /// </summary>
 4     public interface IListSide : IDisposable
 5     {
 6         /// <summary>
 7         /// Get the total of all items
 8         /// </summary>
 9         int ItemsTotal { get; }
10 
11         /// <summary>
12         /// Get count of checked items
13         /// </summary>
14         int CheckedCount { get; }
15 
16         /// <summary>
17         /// Notify others that same items check property changed.
18         /// </summary>
19         Action NotifyCheckedChanged { get; set; }
20 
21         /// <summary>
22         /// Set the check property value of all items
23         /// </summary>
24         /// <param name="setChecked"></param>
25         void UpdateCheckedProperty(bool setChecked);
26     }
27 }

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

 1     /// <summary>
 2     /// The association between CheckboxSide and ListSide
 3     /// </summary>
 4     public class CheckboxAssociation : IDisposable
 5     {
 6         private ICheckboxSide _checkboxSide;
 7         private IListSide _listSide;
 8 
 9         /// <summary>
10         /// Constructor
11         /// </summary>
12         /// <param name="checkboxSide">Represent Checkbox/CheckboxX control</param>
13         /// <param name="listSide">Represent DataGridViewCheckBoxColumn</param>
14         public CheckboxAssociation(ICheckboxSide checkboxSide, IListSide listSide)
15         {
16             _checkboxSide = checkboxSide;
17             _checkboxSide.NotifyCheckedChanged = UpdateListSide;
18 
19             _listSide = listSide;
20             _listSide.NotifyCheckedChanged = UpdateCheckboxSide;
21 
22             UpdateCheckboxSide();
23         }
24 
25         /// <summary>
26         /// Update Checkbox by list
27         /// </summary>
28         public void UpdateCheckboxSide()
29         {
30             CheckState checkState;
31             if (_listSide.CheckedCount == _listSide.ItemsTotal && _listSide.CheckedCount != 0)
32                 checkState = CheckState.Checked;
33             else if (_listSide.CheckedCount < _listSide.ItemsTotal && _listSide.CheckedCount != 0)
34                 checkState = CheckState.Indeterminate;
35             else
36                 checkState = CheckState.Unchecked;
37             _checkboxSide.UpdateCheckedProperty(checkState);
38         }
39 
40         /// <summary>
41         /// Update List item Checked Property value by Checkbox
42         /// </summary>
43         public void UpdateListSide()
44         {
45             _listSide.UpdateCheckedProperty(_checkboxSide.Checked);
46         }
47 
48         public void Dispose()
49         {
50             if (_checkboxSide != null)
51             {
52                 _checkboxSide.Dispose();
53                 _checkboxSide = null;
54             }
55             if (_listSide != null)
56             {
57                 _listSide.Dispose();
58                 _listSide = null;

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

1             _chkAllSource = CheckboxAssociateFactroy.Create(chkPassAll, chLBSystemTemp);
2             chkPassAll.Checked = true;
3             _chkAllSource.UpdateListSide();

注意需要在窗体类内声明私有变量_chkAllSource
