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
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;
