[问题] 代码动态创建的DataGrid不能编辑

dkomj

绑定可以显示内容，但是编辑时，输入的字不显示！

代码如下：
  dtg_WBS := TDataGrid.Create(self);
   dtg_WBS.Parent := self.Panel10;
    dtg_WBS.Align := TAlign.alClient;
    dtg_WBS.DefaultRowHeight := 20;
    dtg_WBS.HeaderMinRowCount := 2;
    dtg_WBS.LookAndFeel := TLookAndFeel.lfFlat;
    dtg_WBS.DefaultFields := false;  
    dtg_WBS.DataSource := DataSetBroker1;
  
  lColumn := TDataGridColumn(dtg_WBS.CreateColumnByClassName('TDataGridColumn'));
    lColumn.Name := 'DataGridColumn_XH';
    lColumn.FieldName :='XH';
    lColumn.Caption := '序号';
    lColumn.Alignment := TAlignment.taCenter;
    lColumn.HeaderAlignment := TAlignment.taCenter;
    lColumn.BandIndex:=1;
    lColumn.Width := 40;

object DataGrid1: TDataGrid
  Left = 24
  Top = 115
  Width = 392
  Height = 208
  Bands = <
    item
    end>
  HeaderPanelRowCount = 1
  TabOrder = 1
  TreeLineColor = clGrayText
  ShowIndicator = True
  DataSource = DataSetBroker1
  Filter.Criteria = {00000000}
  DefaultFields = False
  SummaryGroups = <>
  SummarySeparator = ', '
  object DataGrid1XM: TDataGridColumn
    BandIndex = 0
    RowIndex = 0
    ColumnDef.FieldName = 'XM'
  end
end
