Value does not fall within the expected range

[Louis Bouchard]

Hello,

I got a UserControl with nothing special :

        <telerik:RadTabControl Name="RadTabControlFiche"  Width="835"  VerticalAlignment="Top" HorizontalAlignment="Left"  DisplayMemberPath="Content" DropDownDisplayMode="Collapsed" ScrollMode="Viewport" Background="LightGray" BorderThickness="1" BorderBrush="Black" SelectionChanged="RadTabControlFicheSauvetage_SelectionChanged">

                <telerik:RadTabItem Name="RadTabItemInformations" Padding="9 3" DropDownContent="{Binding Source={StaticResource LocalisationFicheSauvetage}, Path=RadTabItemHeaderInformationsSurveillant}" >

                <telerik:RadTabItem.Header>

                        <StackPanel Orientation="Horizontal" IsHitTestVisible="False">

                            <Image Source="../images/information.png" Height="25" Width="25" />

                            <toolkit:Separator Style="{StaticResource SeparatorMenuStyle}" Width="8"/>                            

                            <TextBlock Text="{Binding Source={StaticResource LocalisationFicheSauvetage}, Path=RadTabItemHeaderInformationsSurveillant}"  FontSize="11"  FontWeight="Normal"/>

                        </StackPanel>

                 </telerik:RadTabItem.Header>

                <telerik:RadTabItem.Content>

                        <StackPanel Orientation="Vertical">

                                            </telerik:QuickAccessToolBar>

                                        </telerik:RadRichTextBoxRibbonUI.QuickAccessToolBar>

  

                                        <!-- <telerik:RadRibbonTab Header="Home">-->

                                        <telerik:RadRibbonTab Header="{Binding Source={StaticResource LocalisationUrgence}, Path=RadRibbonTabHeader}">

...

                                        </telerik:RadRibbonTab>

                                    </telerik:RadRichTextBoxRibbonUI>

                                    <telerik:RadRichTextBox Grid.Row="1" x:Name="richTextBoxInformationsSurveillant" Loaded="richTextBoxInformationsSurveillant_Loaded" IsSpellCheckingEnabled="False"  IsSelectionMiniToolBarEnabled ="True" IsContextMenuEnabled="False" Unloaded="SelectionMiniToolBarHide"/>

                                </Grid>

                            </Border>

                            <Grid Grid.Column="1" Grid.Row="1" Margin="5 5 5 2" Visibility="Collapsed">

                            </Grid>

                        </StackPanel>

                </telerik:RadTabItem.Content>

            </telerik:RadTabItem>
...

And SOMETIME, I have this error :

Any clue?

Hi Louis,

From the information you've provided us with I wasn't able to determine the cause for your error. One possible reason for the issue you are experiencing is if something in your ViewModel is a UI element. However, I'll need more info to be better able to assist you.
I'm attaching a project with a stripped down version of the code you sent us. Please have a look at it and let me know if I am missing something.
