RadGrid Export to excel unable to maintain Decimal Format for number less than 3 digits

[Mohd]

Hi
I am trying to export RadGrid to Excel but it seems that that for numbers less than 4 digits decimal formatting is not maintained in Excel
my code in MainPage.xaml.cs

public partial class MainPage : UserControl
   {
       public MainPage()
       {
           InitializeComponent();
       }
       private void Button1_Click(object sender, RoutedEventArgs e)
       {
           string extension = "xls";
           SaveFileDialog dialog = new SaveFileDialog()
           {
               DefaultExt = extension,
               Filter = String.Format("{1} files (*.{0})|*.{0}|All files (*.*)|*.*", extension, "Excel"),
               FilterIndex = 1
           };
           if (dialog.ShowDialog() == true)
           {
               using (Stream stream = dialog.OpenFile())
               {
                  // MemoryStream ms = new MemoryStream();
                   clubsGrid.Export(stream,
                    new GridViewExportOptions()
                    {
                        Format = ExportFormat.Html,
                        ShowColumnHeaders = true,
                        ShowColumnFooters = true,
                        ShowGroupFooters = false,
                    });
                   //byte[] header = Encoding.UTF8.GetBytes("Premier League");
                   //stream.Write(header, 0, header.Length);
                   //stream.Write(ms.ToArray(), 0, ms.ToArray().Length);
               }
           }

and in xaml my code is like

<UserControl.Resources>
       <my:MyViewModel x:Key="MyViewModel"/>
   </UserControl.Resources>
   <Grid x:Name="LayoutRoot"
         Background="White"
         DataContext="{StaticResource MyViewModel}">
       <Grid.RowDefinitions>
           <RowDefinition Height="*"/>
           <RowDefinition Height="Auto" />
       </Grid.RowDefinitions>
       <Grid.Resources>
           <DataTemplate x:Key="RowDetailsTemplate">
               <telerik:RadGridView Name="playersGrid"
                                    ItemsSource="{Binding Players}"
                                    AutoGenerateColumns="False">
                   <telerik:RadGridView.Columns>
                       <telerik:GridViewDataColumn DataMemberBinding="{Binding Name}"/>
                       <telerik:GridViewDataColumn DataMemberBinding="{Binding Number}"/>
                       <telerik:GridViewDataColumn DataMemberBinding="{Binding Position}"/>
                       <telerik:GridViewDataColumn DataMemberBinding="{Binding Country}"/>
                   </telerik:RadGridView.Columns>
               </telerik:RadGridView>
           </DataTemplate>
       </Grid.Resources>
       <telerik:RadGridView Name="clubsGrid"
                            ItemsSource="{Binding Clubs}"
                            AutoGenerateColumns="False"
                            RowDetailsTemplate="{StaticResource RowDetailsTemplate}"
                            Margin="5,37,5,5" Grid.RowSpan="2">
           <telerik:RadGridView.Columns>
               <telerik:GridViewToggleRowDetailsColumn/>
               <telerik:GridViewDataColumn DataMemberBinding="{Binding Name}"/>
               <telerik:GridViewDataColumn DataMemberBinding="{Binding Established}"
                                           Header="Est."
                                           DataFormatString="{}{0:yyyy}"/>
               <telerik:GridViewDataColumn DataMemberBinding="{Binding StadiumCapacity}"
                                           Header="Stadium"
                                           DataFormatString="{}{0:N2}"/>

           </telerik:RadGridView.Columns>
       </telerik:RadGridView>
       <Button Grid.Row="1"
               Content="Export"
               Click="Button1_Click"
               Margin="5"
               HorizontalAlignment="Left"/>
   </Grid>
