DisplayIndex of RadGridView column not saved correctly

[Alexander]

Hello everyone,
In my application I have 2 RadExpanders. Each RadExpander contains a RadGridView. One RadExpander has IsExpanded set to TRUE other is set to FALSE. Also I am saving RadGridViews settings, using your example. The problem is that for the RadGridView that is placed in RadExpander with IsExpanded set to FALSE, DisplayIndex for all grid's columnsis set to -1, not to the corresponding oreder of the column.
Below is the code I use:

<UserControl x:Class="GridSettings.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
    xmlns:local="clr-namespace:GridSettings"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d"
    d:DesignHeight="300" d:DesignWidth="400">

    <Grid x:Name="LayoutRoot" Background="White">
        <Grid.RowDefinitions>
            <RowDefinition Height="*" />
            <RowDefinition Height="*" />
        </Grid.RowDefinitions>
        <StackPanel>
            <telerik:RadExpander Margin="2"  IsExpanded="False" Header="Not Visible Grid">
                <telerik:RadExpander.Content>
                    <telerik:RadGridView local:RadGridViewSettings.SaveSettings="True" Name="hiddenGrid">
                        <telerik:RadGridView.Columns>
                            <telerik:GridViewDataColumn Header="Name" />
                            <telerik:GridViewDataColumn Header="Surname" />
                        </telerik:RadGridView.Columns>
                    </telerik:RadGridView>
                </telerik:RadExpander.Content>
            </telerik:RadExpander>
            <TextBlock Text="Column index"></TextBlock>
            <ListBox Margin="2"  ItemsSource="{Binding ElementName=hiddenGrid, Path=Columns}">
                <ListBox.ItemTemplate>
                    <DataTemplate>
                        <StackPanel Orientation="Horizontal">
                            <TextBlock Text="{Binding Header}" Margin="2" />
                            <TextBlock Text="Display Index:" Margin="2" />
                            <TextBlock Text="{Binding DisplayIndex}" Margin="2" />
                        </StackPanel>
                    </DataTemplate>
                </ListBox.ItemTemplate>
            </ListBox>
        </StackPanel>

        <StackPanel Grid.Row="1">
            <telerik:RadExpander Margin="2"  IsExpanded="True" Header="Visible Grid">
                <telerik:RadExpander.Content>
                    <telerik:RadGridView local:RadGridViewSettings.SaveSettings="True" Name="visibleGrid">
                        <telerik:RadGridView.Columns>
                            <telerik:GridViewDataColumn Header="Name" />
                            <telerik:GridViewDataColumn Header="Surname" />
                        </telerik:RadGridView.Columns>
                    </telerik:RadGridView>
                </telerik:RadExpander.Content>
            </telerik:RadExpander>
            <TextBlock Text="Column index"></TextBlock>
            <ListBox Margin="2" ItemsSource="{Binding ElementName=visibleGrid, Path=Columns}">
                <ListBox.ItemTemplate>
                    <DataTemplate>
                        <StackPanel Orientation="Horizontal">
                            <TextBlock Text="{Binding Header}" Margin="2" />
                            <TextBlock Text="Display Index:" Margin="2" />
                            <TextBlock Text="{Binding DisplayIndex}" Margin="2" />
                        </StackPanel>
                    </DataTemplate>
                </ListBox.ItemTemplate>
            </ListBox>
        </StackPanel>

    </Grid>
</UserControl>

It seems that settings are saved correctly just for visible in UI grid.

Thank you
Best regards
Alexandru
