GridView 动态列上方添加相应的Combox等控件

Dev中的Gridview控件添加简单的动态列并不复杂，但是有时候需要在在动态列上添加对应的Combox

 1  gvList.BeginUpdate();
 2 if (gcList.DataSource != null)
 3 {
 4    (gcList.DataSource as DataTable).Clear();
 5 }
 6  gvList.Columns.Clear();
 7
 8 //DataTable 形式绑定数据源
 9 DataTable dt = new DataTable();
10                 dt.Columns.Add("PatternPartCD", typeof(string));
11                 dt.Columns.Add("PatternPartNm", typeof(string));
12                 dt.Columns.Add("Size", typeof(Decimal));
13                 dt.Columns.Add("TorlnceL", typeof(Decimal));
14                 dt.Columns.Add("TorlnceR", typeof(Decimal));
15
16                 //手动添加 Gridview列
17                 GridHelper.AddCol(gvList, _presenter._resourceService.GetResourceString("Code"), "PatternPartCD", "PatternPartCD", true, 1, 55, this._riCode);
18                 GridHelper.AddCol(gvList, "* " + _presenter._resourceService.GetResourceString("PatternPartName"), "PatternPartNm", "PatternPartNm", true, 2, 180, null);
19                 GridHelper.AddCol(gvList, _presenter._resourceService.GetResourceString("Standard") + _presenter._resourceService.GetResourceString("Size"), "Size", "Size", true                                     , 3, 70,  null);
20                 GridHelper.AddCol(gvList, _presenter._resourceService.GetResourceString("TorlnceL"), "TorlnceL", "TorlnceL", true, 4, 70,  null);
21                 GridHelper.AddCol(gvList, _presenter._resourceService.GetResourceString("TorlnceR"), "TorlnceR", "TorlnceR", true, 5, 70,  null);

26                 for (i = 0; i < StyleSizeInfo.Count; i++)
27                 {
28                     dt.Columns.Add(StyleSizeInfo[i].SizeCD, typeof(decimal));                                           GridHelper.AddCol(gvList, StyleSizeInfo[i].SizeNm, StyleSizeInfo[i].SizeCD, StyleSizeInfo[i].SizeCD, true, j, 60, txtEdit);
29                     gvList.Columns[j].DisplayFormat.FormatString = "N2";
30                     gvList.Columns[j].DisplayFormat.FormatType = DevExpress.Utils.FormatType.Numeric;
31                     gvList.Columns[j].Tag = "Tag";
32
33                     System.Windows.Forms.ComboBox cboSize = new System.Windows.Forms.ComboBox();
34
35                     cboSize.DropDownStyle = System.Windows.Forms.ComboBoxStyle.DropDownList;
36                     cboSize.Enabled = true; cboSize.FormattingEnabled = true;
37                     cboSize.Location = new Point(462 + i * 60, 0);//重新定位控件的位置39                     cboSize.Name = "cboBrand" + j.ToString();
40                     cboSize.DataSource = dtoList;
41                     cboSize.DisplayMember = "SizeNm";
42                     cboSize.ValueMember = "SizeCD";
43                     this.panelbtn2.Controls.Add(cboSize);
44
45                 dt.Columns.Add("PlusTol", typeof(Decimal));
46                 dt.Columns.Add("MinusTol", typeof(Decimal));
47                 dt.Columns.Add("Measurement", typeof(string));
48
49                 GridHelper.AddCol(gvList, _presenter._resourceService.GetResourceString("PlusTol"), "PlusTol", "PlusTol", true, j, 70, null);
50                 GridHelper.AddCol(gvList, _presenter._resourceService.GetResourceString("MinusTol"), "MinusTol", "MinusTol", true, j + 1, 70, null);
51                 GridHelper.AddCol(gvList, "* " + _presenter._resourceService.GetResourceString("PatternSizeChkMethod"), "Measurement", "Measurement", true, j + 2, 550, null);

注意：

1.最好将添加的控件单独放到一个panel上，方便重新定位或者遍历所有的新添加的控件：

foreach (Control item in panel1.Controls)//
 {
   if (item is System.Windows.Forms.ComboBox)
   {
    (item as System.Windows.Forms.ComboBox).Name = "新名字";
   }
 }

2.如果绑定的是有数据源的控价且控价数据源相同时，需要重新Copy数据源，否则可能会导致添加的控件变得一致：

 1     public class Employee : ICloneable//添加Copy方法到类内
 2     {
 3         public string name { get; set; }
 4         public object Clone()
 5         {
 6             return this.MemberwiseClone();
 7         }
 8     }
 9
10 List<Employee >  EmployeeList = new List<Employee >
11
12 foreach (Employee dto in EmployeeList )
13  {
14     dtoList.Add(dto.Clone() as IF_StyleSizeInfo);
15  }
