添加一列，FieldName为"check"，将ColumnEdit设置为复选框样式。gridview1 editable设置为true

将要绑定的DataTable添加列"check",Type为bool。

绑定DataTable到GridControl。

获取：

string value = gridview.GetDataRow(i)["check"].toString();

value == "true" ||  "" ("false")

设置为多选

gridView1 .OptionsSelection.MultiSelect = true;

gridView1 .OptionsSelection.MultiSelectMode = DevExpress.XtraGrid.Views.Grid.GridMultiSelectMode.RowSelect;

测试的例子如下：

给GridControl添加数据

    string strConn = "###";  
                OracleConnection oconn = new OracleConnection(strConn);  
                string strComm = "select CITY_NAME,DISTRICT_NAME from CC_COMPLAINT_POINT";  
                OracleDataAdapter oda = new OracleDataAdapter(strComm, oconn);  
                DataSet ds = new DataSet();  
                try  
                {  
                    oda.Fill(ds, "cx");  
                    ds.Tables["cx"].Columns.Add("check",System.Type.GetType("System.Boolean"));  
      
                    gridControl1.DataSource = ds.Tables["cx"];  
                    //Rel.DataSource = ds.Tables["cx"];  
                    //Rel.DisplayMember = "DISTRICT_NAME";  
                    //Rel.ValueMember = "CITY_NAME";  
                      
                }  
                catch(Exception ex)  
                {  
                    MessageBox.Show(ex.ToString());  
      
                }  
                finally  
                {  
                    oconn.Close();  
       
                }  

点击测试check按钮响应如下事件（获取被check的数据）

    private void buttonX3_Click(object sender, EventArgs e)  
            {  
                string value="";  
                string strSelected="";  
                for (int i = 0; i < gridView1.RowCount; i++)  
                {  
                    value = gridView1.GetDataRow(i)["check"].ToString();  
                    if (value == "True")  
                    {  
                        strSelected += gridView1.GetRowCellValue(i, "DISTRICT_NAME");  
       
                    }  
                }  
                MessageBox.Show(strSelected);  
            }  

运行结果如下：
