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。
NuGet
Install-Package HZH_Controls目录

用处及效果
因为前面写的表格存在一些问题，本篇文章将对其优化处理，达到以下效果，支持自定义图片和按钮等自定义单元格
准备工作
优化是在原表格基础上做的处理，如果不了解可以移步查看一下
开始
移除UCDataGridView中所有自适应高度相关的功能，移除分页控件
DataGridViewColumnEntity中添加自定义单元格属性
/// <summary> /// 自定义的单元格控件，一个实现IDataGridViewCustomCell的Control /// </summary> /// <value>The custom cell.</value> private Type customCellType = null; public Type CustomCellType { get { return customCellType; } set { if (!typeof(IDataGridViewCustomCell).IsAssignableFrom(value) || !value.IsSubclassOf(typeof(System.Windows.Forms.Control))) throw new Exception("行控件没有实现IDataGridViewCustomCell接口"); customCellType = value; } } |

行控件绑定自定义行
if (item.CustomCellType == null) { Label lbl = new Label(); lbl.Tag = i - (IsShowCheckBox ? 1 : 0); lbl.Name = "lbl_" + item.DataField; lbl.Font = new Font("微软雅黑", 12); lbl.ForeColor = Color.Black; lbl.AutoSize = false; lbl.Dock = DockStyle.Fill; lbl.TextAlign = item.TextAlign; lbl.MouseDown += (a, b) => { Item_MouseDown(a, b); }; c = lbl; } else { Control cc = (Control)Activator.CreateInstance(item.CustomCellType); cc.Dock = DockStyle.Fill; c = cc; } |

支持基本上就完成了全部的控制了，然后看下调用示例
List<DataGridViewColumnEntity> lstCulumns = new List<DataGridViewColumnEntity>(); lstCulumns.Add(new DataGridViewColumnEntity() { Width = 35, WidthType = SizeType.Absolute, CustomCellType = typeof(UCTestGridTable_CustomCellIcon) }); lstCulumns.Add(new DataGridViewColumnEntity() { DataField = "ID", HeadText = "编号", Width = 70, WidthType = SizeType.Absolute }); lstCulumns.Add(new DataGridViewColumnEntity() { DataField = "Name", HeadText = "姓名", Width = 50, WidthType = SizeType.Percent }); lstCulumns.Add(new DataGridViewColumnEntity() { DataField = "Age", HeadText = "年龄", Width = 50, WidthType = SizeType.Percent }); lstCulumns.Add(new DataGridViewColumnEntity() { DataField = "Birthday", HeadText = "生日", Width = 50, WidthType = SizeType.Percent, Format = (a) => { return ((DateTime)a).ToString("yyyy-MM-dd"); } }); lstCulumns.Add(new DataGridViewColumnEntity() { DataField = "Sex", HeadText = "性别", Width = 50, WidthType = SizeType.Percent, Format = (a) => { return ((int)a) == 0 ? "女" : "男"; } }); lstCulumns.Add(new DataGridViewColumnEntity() { Width = 155, WidthType = SizeType.Absolute,CustomCellType=typeof(UCTestGridTable_CustomCell) }); this.ucDataGridView1.Columns = lstCulumns; this.ucDataGridView1.IsShowCheckBox = true; List<object> lstSource = new List<object>(); for (int i = 0; i < 50; i++) { TestGridModel model = new TestGridModel() { ID = i.ToString(), Age = 3 * i, Name = "姓名——" + i, Birthday = DateTime.Now.AddYears(-10), Sex = i % 2 }; lstSource.Add(model); } this.ucDataGridView1.DataSource = lstSource; |
