DataFormatString on sub-property

[Geoff Smith]

I'm trying to get a subproperty formatted, but it doesn't seem to be working. It's just showing the value without any formatting.

My xaml:

<Window x:Class="GridFormatTest.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525" xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation" xmlns:System="clr-namespace:System;assembly=mscorlib">
    <Grid Loaded="Grid_Loaded">
        <telerik:RadGridView HorizontalAlignment="Left" Name="radGridView1" VerticalAlignment="Top" Height="311" Width="503">
            <telerik:RadGridView.Columns>
                <telerik:GridViewDataColumn Header="Works" DataMemberBinding="{Binding Size}" DataFormatString="{}{0:N}"/>
                <telerik:GridViewDataColumn Header="Doesn't work" DataMemberBinding="{Binding SubItem.SubSize}" DataFormatString="{}{0:N}" DataType="{x:Type System:Double}"/>
            </telerik:RadGridView.Columns>
        </telerik:RadGridView>
    </Grid>
</Window>

The code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;

namespace GridFormatTest
{
    public class Order
    {
        public Order()
        {
            this.Size = 12000.0;
            this.SubItem = new SubOrder();
        }

        public double Size { get; private set; }

        public SubOrder SubItem { get; set; }
    }

    public class SubOrder
    {
        public SubOrder()
        {
            this.SubSize = 150000;
        }

        public double SubSize { get; set; }
    }

    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }

        private void Grid_Loaded(object sender, RoutedEventArgs e)
        {
            radGridView1.ItemsSource = new List<Order>
            {
                new Order(),
                new Order()
            };
        }
    }
}

As you can see I've also tried to set the DataType manually, which I noticed was the solution to another similar problem I found on the forums. But that doesn't help.

Any suggestions?

An IValueConverter works fine, so I'll use that for now. But would be great if I could use DataFormatString instead if possible...

Hello Geoff Smith,

This issue has been already fixed. If you upgrade your version to the latest one (version 412) you will be able to achive your goals without using IValueConverter.

Best wishes,
