DevExpress.XtraGrid 导出文本的bug

DevExpress.XtraGrid.GridControl有多个ExportToXXX的方法，提供多种格式的导出，极大节省了人力。如果数据集里面有bool的数据，Grid就会显示成checkbox的形式，导出成pdf、excel当然是没有问题。但导出txt和csv格式时，对应bool字段的值就会空白，没有任何数据导出。这个bug可以在XtraGrid的demo里面看到。导出数据空白的问题在官方资料中目前没有找到资料，只好自己做了。

 以下是导出txt的代码，csv也是稍加修改即可实现。

代码

     private   void  ExportGridToTxt(GridView view,  string  path,  char  spliter)
        {
             if  (view  !=   null )
            {
                StreamWriter sw  =   null ;
                 try
                {
                    sw  =   new  StreamWriter(path,  false , Encoding.Default);
                    StringBuilder sb  =   new  StringBuilder();

                     for  ( int  i  =   0 ; i  <  view.Columns.Count; i ++ )
                    {
                        sb.Append(view.Columns[i].Caption  +  spliter);
                    }
                    sb.AppendLine();

                     for  ( int  i  =   0 ; i  <  view.RowCount; i ++ )
                    {
                        DataRow dr  =  view.GetDataRow(i);
                         for  ( int  j  =   0 ; j  <  view.Columns.Count; j ++ )
                        {
                            GridColumn col  =  view.Columns[j];
                             if  (col.ColumnType  ==   typeof ( bool ))
                            {
                                 bool  val  =  ( bool )(view.GetRowCellValue(i, col));
                                sb.Append(( bool )val  ?   " Y "  :  " N " );
                            }
                             else
                            {
                                 string  displayText  =  view.GetRowCellDisplayText(i, col);
                                sb.Append(displayText);
                            }

                             if  (j  !=  view.Columns.Count  -   1 )
                            {
                                sb.Append(spliter);
                            }
                             else
                            {
                                sb.AppendLine();
                            }
                        }
                    }

                    sw.Write(sb.ToString());
                    sw.Flush();
                }
                 finally
                {
                     if  (sw  !=   null )
                    {
                        sw.Close();
                    }
                }
            }
            
        }
