Multiple DataFormatString for columns

[ShinichiKudo]

Hello,

I have Multiple  ​Format String for columns. I want to binding Multiple  ​DataFormatString for columns. But it doesn't work. 

My source:

View 

<telerik:RadGridView Name="GridWatchPriceTable"  ItemsSource="{Binding ModelData.LstFeeTable}" Style="{DynamicResource GridViewCustomStyle}" 
                                 IsReadOnly="False" >

<telerik:RadGridView.Columns>

   <telerik:GridViewDataColumn DataMemberBinding="{Binding HighPrice}" 
                                                 DataFormatString="{Binding NumberDecimalString}"                                                
                                                Header="{StaticResource ListFeeTable_High}" TextAlignment="Right" IsReadOnly="True"/>

    </telerik:RadGridView.Columns>
</telerik:RadGridView>

 

In ViewModel, I Set value for item in LstFeeTable

  private ListPriceTableInfoModel UpdateDataModel(Symbol item, ListPriceTableInfoModel model)
        {
            model.SymbolId = item.SymbolId;
            model.SymbolName = item.ContractName;

            var baseSymbolInfo = Operator.Instance.GetBaseSymbolById(item.BaseSymbolId);
            if (baseSymbolInfo != null)
            {
                model.FullName = baseSymbolInfo.FullName;
                model.ShortName = baseSymbolInfo.ShortName;
                model.BaseSymbolId = baseSymbolInfo.BaseSymbolId;
                model.NumberDecimal = baseSymbolInfo.NumbreDecimal;
                model.NumberDecimalString = ClientUtils.GetFormatString(baseSymbolInfo,true);
                var exchange = Operator.Instance.GetExchangeInfoById(baseSymbolInfo.ExchangeId);
                model.Exchange = exchange != null ? exchange.ShortName : "";
            }

            model.ClosePrice = (decimal)100.6654;
            model.OpenPrice = (decimal)100.6654;
            model.HighPrice = (decimal)100.6654;
            model.LowPrice = (decimal)100.6654;
            model.YesterdayClose = (decimal)100.6654;
            model.YesterdaySettlement = (decimal)100.6654;
            model.TotalVolume = null;
            model.NetChg = (decimal)100.6654;
            model.NetChgPercent = (decimal)100.6654;
            model.VolBid = null;
            model.Ask = (decimal)100.6654;
            model.VolAsk = null;
            model.VolAskOld = null;
            model.VolBidOld = null;
            model.BidOld = (decimal)100.6654;
            model.VolBidOld = null;
            model.ClosePriceOld = (decimal)100.6654;
            model.LastTrade = (decimal)100.6654;
            model.LastTradeOld = (decimal)100.6654;
            model.Bid = (decimal)100.6654;
            model.BidOld = (decimal)100.6654;
            return model;
        }​
