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
#region 属性
public event DataGridViewEventHandler CheckBoxChangeEvent; public event DataGridViewEventHandler CellClick; public event DataGridViewEventHandler SourceChanged; public List<DataGridViewColumnEntity> Columns
{
get;
set;
} public object DataSource
{
get;
set;
} public bool IsShowCheckBox
{
get;
set;
}
private bool m_isChecked;
public bool IsChecked
{
get
{
return m_isChecked;
} set
{
if (m_isChecked != value)
{
m_isChecked = value;
(this.panCells.Controls.Find("check", false)[] as UCCheckBox).Checked = value;
}
}
} int m_rowHeight = ;
public int RowHeight
{
get
{
return m_rowHeight;
}
set
{
m_rowHeight = value;
this.Height = value;
}
}
#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
public UCDataGridViewTreeRow()
{
InitializeComponent();
this.ucDGVChild.RowType = this.GetType();
this.ucDGVChild.IsAutoHeight = true;
this.SizeChanged += UCDataGridViewTreeRow_SizeChanged;
this.ucDGVChild.ItemClick += (a, b) =>
{
if (CellClick != null)
{
CellClick(a, new DataGridViewEventArgs()
{
CellControl = (a as Control),
CellIndex = (a as Control).Tag.ToInt()
});
}
}; }
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
public void BindingCellData()
{
for (int i = ; i < Columns.Count; i++)
{
DataGridViewColumnEntity com = Columns[i];
var cs = this.panCells.Controls.Find("lbl_" + com.DataField, false);
if (cs != null && cs.Length > )
{
var pro = DataSource.GetType().GetProperty(com.DataField);
if (pro != null)
{
var value = pro.GetValue(DataSource, null);
if (com.Format != null)
{
cs[].Text = com.Format(value);
}
else
{
cs[].Text = value.ToStringExt();
}
}
}
}
panLeft.Tag = ;
var proChildrens = DataSource.GetType().GetProperty("Childrens");
if (proChildrens != null)
{
var value = proChildrens.GetValue(DataSource, null);
if (value != null)
{
int intSourceCount = ;
if (value is DataTable)
{
intSourceCount = (value as DataTable).Rows.Count;
}
else if (typeof(IList).IsAssignableFrom(value.GetType()))
{
intSourceCount = (value as IList).Count;
}
if (intSourceCount > )
{
panLeft.BackgroundImage = Properties.Resources.caret_right;
panLeft.Enabled = true;
panChildGrid.Tag = value;
}
else
{
panLeft.BackgroundImage = null;
panLeft.Enabled = false;
panChildGrid.Tag = null;
}
}
else
{
panLeft.BackgroundImage = null;
panLeft.Enabled = false;
panChildGrid.Tag = null;
}
}
else
{
panLeft.BackgroundImage = null;
panLeft.Enabled = false;
panChildGrid.Tag = null;
}
}
实现函数绑定列
public void ReloadCells()
{
try
{
ControlHelper.FreezeControl(this, true);
this.panCells.Controls.Clear();
this.panCells.ColumnStyles.Clear(); int intColumnsCount = Columns.Count();
if (Columns != null && intColumnsCount > )
{
if (IsShowCheckBox)
{
intColumnsCount++;
}
this.panCells.ColumnCount = intColumnsCount;
for (int i = ; i < intColumnsCount; i++)
{
Control c = null;
if (i == && IsShowCheckBox)
{
this.panCells.ColumnStyles.Add(new System.Windows.Forms.ColumnStyle(SizeType.Absolute, 30F)); UCCheckBox box = new UCCheckBox();
box.Name = "check";
box.TextValue = "";
box.Size = new Size(, );
box.Dock = DockStyle.Fill;
box.CheckedChangeEvent += (a, b) =>
{
IsChecked = box.Checked;
this.ucDGVChild.Rows.ForEach(p => p.IsChecked = box.Checked);
if (CheckBoxChangeEvent != null)
{
CheckBoxChangeEvent(a, new DataGridViewEventArgs()
{
CellControl = box,
CellIndex =
});
}
};
c = box;
}
else
{
var item = Columns[i - (IsShowCheckBox ? : )];
this.panCells.ColumnStyles.Add(new System.Windows.Forms.ColumnStyle(item.WidthType, item.Width)); Label lbl = new Label();
lbl.Tag = i - (IsShowCheckBox ? : );
lbl.Name = "lbl_" + item.DataField;
lbl.Font = new Font("微软雅黑", );
lbl.ForeColor = Color.Black;
lbl.AutoSize = false;
lbl.Dock = DockStyle.Fill;
lbl.TextAlign = ContentAlignment.MiddleCenter;
lbl.MouseDown += (a, b) =>
{
Item_MouseDown(a, b);
};
c = lbl;
}
this.panCells.Controls.Add(c, i, );
} }
}
finally
{
ControlHelper.FreezeControl(this, false);
}
}
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
private void panLeft_MouseDown(object sender, MouseEventArgs e)
{
try
{
ControlHelper.FreezeControl(this.FindForm(), true);
if (panLeft.Tag.ToInt() == )
{
var value = panChildGrid.Tag;
if (value != null)
{
panLeft.BackgroundImage = Properties.Resources.caret_down;
panLeft.Tag = ;
int intSourceCount = ;
if (value is DataTable)
{
intSourceCount = (value as DataTable).Rows.Count;
}
else if (typeof(IList).IsAssignableFrom(value.GetType()))
{
intSourceCount = (value as IList).Count;
}
this.panChildGrid.Height = RowHeight * intSourceCount;
if (panChildGrid.Height > )
{
if (value != this.ucDGVChild.DataSource)
{
this.ucDGVChild.Columns = Columns;
this.ucDGVChild.RowHeight = RowHeight;
this.ucDGVChild.HeadPadingLeft = this.panLeft.Width;
this.ucDGVChild.IsShowCheckBox = IsShowCheckBox;
this.ucDGVChild.DataSource = value;
this.ucDGVChild.Rows.ForEach(p => p.IsChecked =this.IsChecked);
}
}
} }
else
{
panLeft.Tag = ;
panChildGrid.Height = ;
panLeft.BackgroundImage = Properties.Resources.caret_right;
}
}
finally
{
ControlHelper.FreezeControl(this.FindForm(), false);
}
}
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
void UCDataGridViewTreeRow_SizeChanged(object sender, EventArgs e)
{
if (this.Parent.Parent.Parent != null && this.Parent.Parent.Parent.Name == "panChildGrid" && this.panLeft.Tag.ToInt() == )
{
int intHeight = this.Parent.Parent.Controls[].Controls.ToArray().Sum(p => p.Height);
if (this.Parent.Parent.Parent.Height != intHeight)
this.Parent.Parent.Parent.Height = intHeight;
}
}

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
this.ucDataGridView1.RowType = typeof(UCDataGridViewTreeRow);
this.ucDataGridView1.IsAutoHeight = true; List<DataGridViewColumnEntity> lstCulumns = new List<DataGridViewColumnEntity>();
lstCulumns.Add(new DataGridViewColumnEntity() { DataField = "ID", HeadText = "编号", Width = , WidthType = SizeType.Absolute });
lstCulumns.Add(new DataGridViewColumnEntity() { DataField = "Name", HeadText = "姓名", Width = , WidthType = SizeType.Percent });
lstCulumns.Add(new DataGridViewColumnEntity() { DataField = "Age", HeadText = "年龄", Width = , WidthType = SizeType.Percent });
lstCulumns.Add(new DataGridViewColumnEntity() { DataField = "Birthday", HeadText = "生日", Width = , WidthType = SizeType.Percent, Format = (a) => { return ((DateTime)a).ToString("yyyy-MM-dd"); } });
lstCulumns.Add(new DataGridViewColumnEntity() { DataField = "Sex", HeadText = "性别", Width = , WidthType = SizeType.Percent, Format = (a) => { return ((int)a) == ? "女" : "男"; } });
this.ucDataGridView1.Columns = lstCulumns;
this.ucDataGridView1.IsShowCheckBox = true;
List<object> lstSource = new List<object>();
for (int i = ; i < ; i++)
{
TestModel model = new TestModel()
{
ID = i.ToString(),
Age = * i,
Name = "姓名——" + i,
Birthday = DateTime.Now.AddYears(-),
Sex = i %
};
lstSource.Add(model);
AddChilds(model, );
} var page = new UCPagerControl2();
page.DataSource = lstSource;
this.ucDataGridView1.Page = page;
this.ucDataGridView1.First(); private void AddChilds(TestModel tm, int intCount)
{
if (intCount <= )
return;
tm.Childrens = new List<TestModel>();
for (int i = ; i < ; i++)
{
TestModel model = new TestModel()
{
ID = i.ToString(),
Age = * i,
Name = intCount + "——" + i,
Birthday = DateTime.Now.AddYears(-),

tm.Childrens.Add(model);
