winform DataGridView-----2
上一篇对Data'gridView做了简单的封装，基本能满足正常开发了，后来我发现一个单元中同时会又左边图标右边文字的情况，这次就把这个也加上。所以我自定义歌一个组件。
自定义 DataGridView 组件：
public partial class GridList : DataGridView
{
private Dictionary<int, Image> dic { get; set; }
public void SetHeader(List<dataGridViewModel> viewModel)
{
dic = new Dictionary<int, Image>();
this.CellFormatting += Grid_cellFormartting;
foreach (var item in viewModel)
{
switch (item.colType)
{
case ColType.文本:
this.AutoGenerateColumns = false;
TextAndImageColumn ColumnRoleID = new TextAndImageColumn();
ColumnRoleID.DataPropertyName = item.colName;
ColumnRoleID.DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleLeft;
ColumnRoleID.Name = item.colName;
ColumnRoleID.HeaderText = item.colTitle;
this.Columns.Add(ColumnRoleID);
break;
case ColType.图标://单独一列显示图标
this.SetImage();
break;
case ColType.图标文本://单独一列显示图标
SetCellImgOrText(item.cell);
break;
case ColType.按钮:
this.SetButton(item.TitleData);
break;
default:
break;
}
}
}
/// <summary>

private void SetCellImgOrText(CellType cellType)
{
dic.Add(cellType.ColIndex, cellType.ImageType);
}

private void SetImage()
{
DataGridViewImageColumn Imange = new DataGridViewImageColumn();
Imange.ImageLayout = DataGridViewImageCellLayout.Zoom;
// Imange.HeaderText = "图标";
this.Columns.Add(Imange);
}

{
if (title == null)

{

Text = title.Text,
UseColumnTextForButtonValue = true,
DataPropertyName = "operate",

HeaderText = title.headText
};
select.FlatStyle = FlatStyle.Flat;
select.Width = 20;
select.DefaultCellStyle.ForeColor = string.IsNullOrEmpty(title.color) ? Color.Black : colorHx16toRGB(title.color);
this.Columns.Add(select);

Model:
public enum ColType
{
文本,
图标,
图标文本,
按钮
}
public class dataGridViewModel
{
public string colName { get; set; }
public string colTitle { get; set; }
public ColType colType { get; set; }
public Title TitleData { get; set; }
public CellType cell { get; set; }
}
/// <summary>
/// 图标，文字
/// </summary>
public class CellType
{
public int ColIndex { get; set; }
public Image ImageType { get; set; }
}
/// <summary>
/// 按钮
/// </summary>
public class Title
{
public string headTitle { get; set; }
public string Text { get; set; }
public string headText { get; set; }
public string color { get; set; }
}
实现：
从心编译工程，工具箱中会出现自定义控件：
//设置行表头的颜色
//dataGridView_Mark.SetHeadColor("#F5F5F5");
gridList1.SetHeadColor(250, 250, 250);
//表头文字颜色
// dataGridView_File2.SetHeadFontColor("#F5F5F5");
gridList1.SetHeadFontColor(95, 95, 95);
//行表头文字类型
gridList1.SetHeadFontType(new Font("楷体", 8, FontStyle.Bold));
//改变标题的行高
gridList1.SetHeadRowHeight(30);
//去除第一列空列
gridList1.SetRowHeadersVisible();
//行占满
gridList1.SetCellRowFull();
//去除最后一行空行
gridList1.SetAllowUserToAddRows();
//标题居中
gridList1.SetHeadCenter();
List<dataGridViewModel> viewModel = new List<dataGridViewModel>()
{
new dataGridViewModel(){colType=ColType.图标},
new dataGridViewModel(){colName="title",colTitle="标题",colType=ColType.图标文本,cell= new CellType(){ColIndex=2,ImageType=Properties.Resources.excel } },
new dataGridViewModel(){colName="title1",colTitle="标题",colType=ColType.文本},
new dataGridViewModel(){colName="title2",colTitle="标题",colType=ColType.文本},
new dataGridViewModel(){colName="title3",colTitle="标题",colType=ColType.文本},
new dataGridViewModel(){colName="title4",colTitle="标题",colType=ColType.文本},
new dataGridViewModel(){colName="title5",colTitle="标题",colType=ColType.文本},
new dataGridViewModel(){ colType = ColType.按钮,TitleData=new Title(){ headTitle="btnfile4",Text="按钮",headText="操作" } },
};
gridList1.SetHeader(viewModel);
//设置某列隐藏
// dataGridView_ReportList.SetColVisible(new string[] { "PKID", "customer" });
Dictionary<int, int> colWidth = new Dictionary<int, int>()
{
[0] = 30,
[6] = 60,
};
////设置列宽
gridList1.SetColWidth(colWidth);
for (int i = 0; i < 30; i++)
{
gridList1.Rows.Add(Properties.Resources.excel, "dsf", "dfsfs", "dsfsdf", "dfsf", "dfsf", "dfsfs");
}
