DataGridViewComboBoxColumn 手动绑定数据源

 

 
   
   1  
    
  // 
  默认将AllowUserToAddRows设置成了False,所以创建一个DataGridViewRow添加到DataGridView中 
  
 
   2  
   
  DataGridViewRow dgvr  
  = 
    
  new 
   DataGridViewRow();
 
   3  
  dgvDownloadList.Rows.Add(dgvr);
 
   4  
   
 
   5  
   
  // 
  获取数据源 
  
 
   6  
   
  List 
  < 
  ServiceInterface.dmsManageWCFService.dmsDocumentInfo 
  > 
   DIList  
  = 
   PDMService.DmsManageWcfServiceJoint.GetAllHistroyVersion(item.DocGUID);
 
   7  
  
 
   8  
  DataTable dtVersion  
  = 
    
  new 
   DataTable();
 
   9  
  DataColumn dcVersion  
  = 
    
  new 
   DataColumn( 
  " 
  Version 
  " 
  ); 
  // 
  显示Name 
  
 
  10  
   
  DataColumn dcVerGUID  
  = 
    
  new 
   DataColumn( 
  " 
  VerGUID 
  " 
  ); 
  // 
  绑定的Value 
  
 
  11  
   
  dtVersion.Columns.Add(dcVersion);
 
  12  
  dtVersion.Columns.Add(dcVerGUID);
 
  13  
  
 
  14  
   
  foreach 
   (ServiceInterface.dmsManageWCFService.dmsDocumentInfo cVerDoc  
  in 
   DIList)
 
  15  
  {
 
  16  
       dtVersion.Rows.Add(cVerDoc.DocVer, cVerDoc.VerGUID);
 
  17  
  }
 
  18  
  
 
  19  
  ((DataGridViewComboBoxCell)dgvDownloadList.Rows[0].Cells[ 
  " 
  Version 
  " 
  ]).DataSource  
  = 
   dtVersion;
 
  20  
  ((DataGridViewComboBoxCell)dgvDownloadList.Rows[0].Cells[ 
  " 
  Version 
  " 
  ]).ValueMember  
  = 
    
  " 
  VerGUID 
  " 
  ;
 
  21  
  ((DataGridViewComboBoxCell)dgvDownloadList.Rows[0].Cells[ 
  " 
  Version 
  " 
  ]).DisplayMember  
  = 
    
  " 
  Version 
  " 
  ;
 
  22  
   
 
  23  
   
  // 
  绑定初始值显示Name，就要绑定Value 
  
 
  24  
   
  ((DataGridViewComboBoxCell)dgvDownloadList.Rows[0].Cells[ 
  " 
  Version 
  " 
  ]).Value  
  = 
   item.DocVerGuid;
 
  25  
  
 
  26  
   
  // 
  绑定默认空值 
  
 
  27  
   
  ((DataGridViewComboBoxColumn)dgvDownloadList.Columns[ 
  " 
  Version 
  " 
  ]).DefaultCellStyle.NullValue  
  = 
    
  " 
  --请选择--
