前提
入行已经7,8年了，一直想做一套漂亮点的自定义控件，于是就有了本系列文章。

用处及效果
准备工作
这个是在前面表格的基础上，扩展了自定义行实现的，当然也修改了一些列表控件以兼容
如果对前面的表格控件不了解，请移步查看
开始
实现树表格的思路就是，在行控件中再添加一个无标题的表格控件，当需要显示子节点的时候，将子节点数据加载到行里的表格控件中，然后处理一下事件，让事件可以穿透到最顶层就行了。
另外我们前面表格中的行个数是根据高度大小自动计算的，这里就会出现问题，当出现子节点表格的时候，就会导致重算个数和高度，所有我们在表格列表控件增加一个属性来禁用这个自动计算。
添加一个用户控件，命名UCDataGridViewTreeRow，实现接口IDataGridViewRow
属性
1 #region 属性
2 public event DataGridViewEventHandler CheckBoxChangeEvent;
3
4 public event DataGridViewEventHandler CellClick;
5
6 public event DataGridViewEventHandler SourceChanged;
7
8 public List<DataGridViewColumnEntity> Columns
9 {
10 get;
11 set;
12 }
13
14 public object DataSource
15 {
16 get;
17 set;
18 }
19
20 public bool IsShowCheckBox
21 {
22 get;
23 set;
24 }
25 private bool m_isChecked;
26 public bool IsChecked
27 {
28 get
29 {
30 return m_isChecked;
31 }
32
33 set
34 {
35 if (m_isChecked != value)
36 {
37 m_isChecked = value;
38 (this.panCells.Controls.Find("check", false)[0] as UCCheckBox).Checked = value;
39 }
40 }
41 }
42
43 int m_rowHeight = 40;
44 public int RowHeight
45 {
46 get
47 {
48 return m_rowHeight;
49 }
50 set
51 {
52 m_rowHeight = value;
53 this.Height = value;
54 }
55 }
56 #endregion构造函数处理一写东西，注意 this.ucDGVChild.ItemClick ，这个是将子节点表格的点击事件向上传递
1 public UCDataGridViewTreeRow()
2 {
3 InitializeComponent();
4 this.ucDGVChild.RowType = this.GetType();
5 this.ucDGVChild.IsAutoHeight = true;
6 this.SizeChanged += UCDataGridViewTreeRow_SizeChanged;
7 this.ucDGVChild.ItemClick += (a, b) =>
8 {
9 if (CellClick != null)
10 {
11 CellClick(a, new DataGridViewEventArgs()
12 {
13 CellControl = (a as Control),
14 CellIndex = (a as Control).Tag.ToInt()
15 });
16 }
17 };
18
19 }实现接口函数BindingCellData，主要处理一下数据绑定后将子节点数据向下传递
1 public void BindingCellData()
2 {
3 for (int i = 0; i < Columns.Count; i++)
4 {
5 DataGridViewColumnEntity com = Columns[i];
6 var cs = this.panCells.Controls.Find("lbl_" + com.DataField, false);
7 if (cs != null && cs.Length > 0)
8 {
9 var pro = DataSource.GetType().GetProperty(com.DataField);
10 if (pro != null)
11 {
12 var value = pro.GetValue(DataSource, null);
13 if (com.Format != null)
14 {
15 cs[0].Text = com.Format(value);
16 }
17 else
18 {
19 cs[0].Text = value.ToStringExt();
20 }
21 }
22 }
23 }
24 panLeft.Tag = 0;
25 var proChildrens = DataSource.GetType().GetProperty("Childrens");
26 if (proChildrens != null)
27 {
28 var value = proChildrens.GetValue(DataSource, null);
29 if (value != null)
30 {
31 int intSourceCount = 0;
32 if (value is DataTable)
33 {
34 intSourceCount = (value as DataTable).Rows.Count;
35 }
36 else if (typeof(IList).IsAssignableFrom(value.GetType()))
37 {
38 intSourceCount = (value as IList).Count;
39 }
40 if (intSourceCount > 0)
41 {
42 panLeft.BackgroundImage = Properties.Resources.caret_right;
43 panLeft.Enabled = true;
44 panChildGrid.Tag = value;
45 }
46 else
47 {
48 panLeft.BackgroundImage = null;
49 panLeft.Enabled = false;
50 panChildGrid.Tag = null;
51 }
52 }
53 else
54 {

56 panLeft.Enabled = false;

58 }
59 }
60 else
61 {
62 panLeft.BackgroundImage = null;
63 panLeft.Enabled = false;
64 panChildGrid.Tag = null;
65 }
66 }实现函数绑定列

167 }我这里写死了，如果要使用树表格的话，子数据就要用属性Childrens，比如下面的实体就是了
public class TestModel
{
public string ID { get; set; }
public string Name { get; set; }
public int Age { get; set; }
public DateTime Birthday { get; set; }
public int Sex { get; set; }
public List<TestModel> Childrens { get; set; }
}使用实例如下
1 this.ucDataGridView1.RowType = typeof(UCDataGridViewTreeRow);
2 this.ucDataGridView1.IsAutoHeight = true;
3
4 List<DataGridViewColumnEntity> lstCulumns = new List<DataGridViewColumnEntity>();
5 lstCulumns.Add(new DataGridViewColumnEntity() { DataField = "ID", HeadText = "编号", Width = 70, WidthType = SizeType.Absolute });
6 lstCulumns.Add(new DataGridViewColumnEntity() { DataField = "Name", HeadText = "姓名", Width = 50, WidthType = SizeType.Percent });
7 lstCulumns.Add(new DataGridViewColumnEntity() { DataField = "Age", HeadText = "年龄", Width = 50, WidthType = SizeType.Percent });
8 lstCulumns.Add(new DataGridViewColumnEntity() { DataField = "Birthday", HeadText = "生日", Width = 50, WidthType = SizeType.Percent, Format = (a) => { return ((DateTime)a).ToString("yyyy-MM-dd"); } });
9 lstCulumns.Add(new DataGridViewColumnEntity() { DataField = "Sex", HeadText = "性别", Width = 50, WidthType = SizeType.Percent, Format = (a) => { return ((int)a) == 0 ? "女" : "男"; } });
10 this.ucDataGridView1.Columns = lstCulumns;
11 this.ucDataGridView1.IsShowCheckBox = true;
12 List<object> lstSource = new List<object>();
13 for (int i = 0; i < 200; i++)
14 {
15 TestModel model = new TestModel()
16 {
17 ID = i.ToString(),
18 Age = 3 * i,
19 Name = "姓名——" + i,
20 Birthday = DateTime.Now.AddYears(-10),
21 Sex = i % 2
22 };
23 lstSource.Add(model);
24 AddChilds(model, 5);
25 }
26
27 var page = new UCPagerControl2();
28 page.DataSource = lstSource;
29 this.ucDataGridView1.Page = page;
30 this.ucDataGridView1.First();
31
32
33
34
35 private void AddChilds(TestModel tm, int intCount)
36 {
37 if (intCount <= 0)
38 return;
39 tm.Childrens = new List<TestModel>();
40 for (int i = 0; i < 5; i++)
41 {
42 TestModel model = new TestModel()
43 {
44 ID = i.ToString(),
45 Age = 3 * i,
46 Name = intCount + "——" + i,
47 Birthday = DateTime.Now.AddYears(-10),
48 Sex = i % 2
49 };
50 tm.Childrens.Add(model);
51 AddChilds(model, intCount - 1);
52 }
53 }最后的话
