（四十七）c#Winform自定义控件-树表格（treeGrid）-HZHControls
官网
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 { 55 panLeft.BackgroundImage = null; 56 panLeft.Enabled = false; 57 panChildGrid.Tag = null; 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
1 public void ReloadCells() 2 { 3 try 4 { 5 ControlHelper.FreezeControl(this, true); 6 this.panCells.Controls.Clear(); 7 this.panCells.ColumnStyles.Clear(); 8 9 int intColumnsCount = Columns.Count(); 10 if (Columns != null && intColumnsCount > 0) 11 { 12 if (IsShowCheckBox) 13 { 14 intColumnsCount++; 15 } 16 this.panCells.ColumnCount = intColumnsCount; 17 for (int i = 0; i < intColumnsCount; i++) 18 { 19 Control c = null; 20 if (i == 0 && IsShowCheckBox) 21 { 22 this.panCells.ColumnStyles.Add(new System.Windows.Forms.ColumnStyle(SizeType.Absolute, 30F)); 23 24 UCCheckBox box = new UCCheckBox(); 25 box.Name = "check"; 26 box.TextValue = ""; 27 box.Size = new Size(30, 30); 28 box.Dock = DockStyle.Fill; 29 box.CheckedChangeEvent += (a, b) => 30 { 31 IsChecked = box.Checked; 32 this.ucDGVChild.Rows.ForEach(p => p.IsChecked = box.Checked); 33 if (CheckBoxChangeEvent != null) 34 { 35 CheckBoxChangeEvent(a, new DataGridViewEventArgs() 36 { 37 CellControl = box, 38 CellIndex = 0 39 }); 40 } 41 }; 42 c = box; 43 } 44 else 45 { 46 var item = Columns[i - (IsShowCheckBox ? 1 : 0)]; 47 this.panCells.ColumnStyles.Add(new System.Windows.Forms.ColumnStyle(item.WidthType, item.Width)); 48 49 Label lbl = new Label(); 50 lbl.Tag = i - (IsShowCheckBox ? 1 : 0); 51 lbl.Name = "lbl_" + item.DataField; 52 lbl.Font = new Font("微软雅黑", 12); 53 lbl.ForeColor = Color.Black; 54 lbl.AutoSize = false; 55 lbl.Dock = DockStyle.Fill; 56 lbl.TextAlign = ContentAlignment.MiddleCenter; 57 lbl.MouseDown += (a, b) => 58 { 59 Item_MouseDown(a, b); 60 }; 61 c = lbl; 62 } 63 this.panCells.Controls.Add(c, i, 0); 64 } 65 66 } 67 } 68 finally 69 { 70 ControlHelper.FreezeControl(this, false); 71 } 72 }
当点击展开图标的时候处理子节点的数据绑定以及高度计算
1 private void panLeft_MouseDown(object sender, MouseEventArgs e) 2 { 3 try 4 { 5 ControlHelper.FreezeControl(this.FindForm(), true); 6 if (panLeft.Tag.ToInt() == 0) 7 { 8 var value = panChildGrid.Tag; 9 if (value != null) 10 { 11 panLeft.BackgroundImage = Properties.Resources.caret_down; 12 panLeft.Tag = 1; 13 int intSourceCount = 0; 14 if (value is DataTable) 15 { 16 intSourceCount = (value as DataTable).Rows.Count; 17 } 18 else if (typeof(IList).IsAssignableFrom(value.GetType())) 19 { 20 intSourceCount = (value as IList).Count; 21 } 22 this.panChildGrid.Height = RowHeight * intSourceCount; 23 if (panChildGrid.Height > 0) 24 { 25 if (value != this.ucDGVChild.DataSource) 26 { 27 this.ucDGVChild.Columns = Columns; 28 this.ucDGVChild.RowHeight = RowHeight; 29 this.ucDGVChild.HeadPadingLeft = this.panLeft.Width; 30 this.ucDGVChild.IsShowCheckBox = IsShowCheckBox; 31 this.ucDGVChild.DataSource = value; 32 this.ucDGVChild.Rows.ForEach(p => p.IsChecked =this.IsChecked); 33 } 34 } 35 } 36 37 } 38 else 39 { 40 panLeft.Tag = 0; 41 panChildGrid.Height = 0; 42 panLeft.BackgroundImage = Properties.Resources.caret_right; 43 } 44 } 45 finally 46 { 47 ControlHelper.FreezeControl(this.FindForm(), false); 48 } 49 }
承载子节点表格的panel 在大小改变的时候，处理父级表格的大小。来防止出现多个滚动条
1 void UCDataGridViewTreeRow_SizeChanged(object sender, EventArgs e) 2 { 3 if (this.Parent.Parent.Parent != null && this.Parent.Parent.Parent.Name == "panChildGrid" && this.panLeft.Tag.ToInt() == 1) 4 { 5 int intHeight = this.Parent.Parent.Controls[0].Controls.ToArray().Sum(p => p.Height); 6 if (this.Parent.Parent.Parent.Height != intHeight) 7 this.Parent.Parent.Parent.Height = intHeight; 8 } 9 }

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 }
