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
(三十二)c#Winform自定义控件-表格
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
///
/// 自定义的单元格控件,一个实现IDataGridViewCustomCell的Control
///
/// The custom cell.
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 lstCulumns = new List();
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;
