Export when grouping problems

[Robert]

Hello,
I have a problem exporting to a text file while grouping the data.

<!-- Window1.xaml -->
<Window x:Class="WpfTelerikRadGridViewTest.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
    Title="Window1" Width="800" Height="600" >
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition />
            <RowDefinition Height="Auto" />
        </Grid.RowDefinitions>
        <telerik:RadGridView Name="radGridView1" ItemsSource="{Binding}" />
        <Button Grid.Row="1" Click="ButtonBase_OnClick">Save</Button>
    </Grid>
</Window>

// Window1.xaml.cs
public partial class Window1
{
    public Window1()
    {
        InitializeComponent();

        var list = new ObservableCollection<string>();

        list.Add("HELLO1");
        list.Add("HELLO2");
        list.Add("HELLO3");
        list.Add("HELLO4");
        list.Add("HELLO5");

        DataContext = list;
    }

    private void ButtonBase_OnClick(object sender, RoutedEventArgs e)
    {
        var s = radGridView1.ToText();
    }
}

When i press the save button the variable 's' gets the _correct_ value:
"\r\nHELLO1\r\nHELLO2\r\nHELLO3\r\nHELLO4\r\nHELLO5\r\n"

When i press the save button while grouping the column i get the following value on 's': 
"\r\nHELLO1\r\n\r\nHELLO1\r\nHELLO2\r\n\r\nHELLO1\r\n\r\nHELLO1\r\nHELLO2\r\nHELLO3\r\n\r\nHELLO1\r\n\r\nHELLO1\r\nHELLO2\r\n\r\nHELLO1\r\n\r\nHELLO1\r\nHELLO2\r\nHELLO3\r\nHELLO4\r\n\r\nHELLO1\r\n\r\nHELLO1\r\nHELLO2\r\n\r\nHELLO1\r\n\r\nHELLO1\r\nHELLO2\r\nHELLO3\r\n\r\nHELLO1\r\n\r\nHELLO1\r\nHELLO2\r\n\r\nHELLO1\r\n\r\nHELLO1\r\nHELLO2\r\nHELLO3\r\nHELLO4\r\nHELLO5\r\n\r\nHELLO1\r\n\r\nHELLO1\r\nHELLO2\r\n\r\nHELLO1\r\n\r\nHELLO1\r\nHELLO2\r\nHELLO3\r\n\r\nHELLO1\r\n\r\nHELLO1\r\nHELLO2\r\n\r\nHELLO1\r\n\r\nHELLO1\r\nHELLO2\r\nHELLO3\r\nHELLO4\r\n\r\nHELLO1\r\n\r\nHELLO1\r\nHELLO2\r\n\r\nHELLO1\r\n\r\nHELLO1\r\nHELLO2\r\nHELLO3\r\n\r\nHELLO1\r\n\r\nHELLO1\r\nHELLO2\r\n\r\nHELLO1\r\n\r\nHELLO1\r\nHELLO2\r\nHELLO3\r\nHELLO4\r\nHELLO5\r\n"

This means that i cant export a grid if the user is grouping. I thought that it would generate a sorted grid. This behavior also applies to ToHtml.

Hello Robert,

When you bind the grid to a collection of strings it is their length that is displayed. Maybe this is causing the confusion.

I have prepared a sample project with real data and exporting works fine. Please find the sample project attached. Here is what I get when I group by country and export the grid:

Name    Number  Position    Country
Petr Čech   1   GK  Czech Republic

Jamie Carragher 23  DF  England
Steven Gerrard  8   MF  England
Rio Ferdinand   5   DF  England
Wayne Rooney    10  FW  England
John Terry  26  DF  England
Frank Lampard   8   MF  England

Nicolas Anelka  39  FW  France
Gaël Clichy 22  DF  France

Edwin van der Sar   1   GK  Netherlands
Robin van Persie    11  FW  Netherlands

Pepe Reina  25  GK  Spain
Fernando Torres 9   FW  Spain
Manuel Almunia  1   GK  Spain
Cesc Fàbregas   4   MF  Spain

Ryan Giggs  11  MF  Wales

I hope this helps.

Hello Ross
Thanks for the example project! It works great until i change the references to the version of telerik that i have (2009.1.312.35). Then i get the following output. I only took a part of it because it is about 385lines!!

Name    Number  Position    Country

Petr Čech   1   GK  Czech Republic

Name    Number  Position    Country

Petr Čech   1   GK  Czech Republic

Jamie Carragher 23  DF  England

Steven Gerrard  8   MF  England

Rio Ferdinand   5   DF  England

Wayne Rooney    10  FW  England

John Terry  26  DF  England

Frank Lampard   8   MF  England

Name    Number  Position    Country

Petr Čech   1   GK  Czech Republic

Name    Number  Position    Country

Petr Čech   1   GK  Czech Republic

Jamie Carragher 23  DF  England ...

again it seems like the data is duplicated.

Hello Robert,

You will need to upgrade to our Latest Internal Build version. The version you are using is almost 9 months old. You can download our Latest Internal Build version from your Client.NET.

All the best,
