新增一列,FieldName為 "check"，將ColumnEdit 設定為 複選框 樣式。gridview1 editable設定為true

  將要繫結的DataTable新增列 "check",Type 為 bool。

  繫結DataTable到GridControl。

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

         value == "true" ||  "" ("false")

 設定為多選

gridView1 .OptionsSelection.MultiSelect = true;

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

測試的例子如下：

給gridcontrol新增資料

            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();
 
            }
 

     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);
        }
