C# 利用ListDictionary绑定控件到FlexGird

//生成ListDictionary对象
ListDictionary dtBumonMap = getListDictionary(ds.Tables[0]);
//生成CellStyle对象
CellStyle cmbBumonStyle = this.flxData.Styles.Add("cmbBumonStyle");
cmbBumonStyle.DataMap = dtBumonMap;
cmbBumonStyle.DataType = typeof(string);
cmbBumonStyle.BackColor = Color.White;
cr = this.flxData.GetCellRange(1, this.flxData.Cols["部門"].Index, 1, this.flxData.Cols["部門"].Index);
cr.Style = cmbBumonStyle;
