C# Winform中DataGridView的DataGridViewComboBoxColumn使用方法

下面介绍Winform中DataGridView的DataGridViewComboBoxColumn的使用方法：

 

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--";
