IsSynchronizedWithCurrentItem="True" with extended(multiple) row selection

[Christoph]

When I set IsSynchronizedWithCurrentItem="True", the current row gets the row selection indicator (chevron). However, I have extended selection enabled - to be able to Ctrl+Click-add multiple rows. In this case, only the first row I select gets the chevron - is there a way to extend this to all selected items? (or restyle the area where the chevron is displayed entirely)

Hello Christoph,

 

Indeed a possible approach in this case is to predefine the template of GridViewRow and modify its Selected State as follows:

<MultiTrigger>
                                <MultiTrigger.Conditions>
                                    <Condition Property="IsSelected" Value="True"/>
                                    <Condition Property="DisplayVisualCues" Value="True"/>
                                </MultiTrigger.Conditions>
                                <Setter Property="Visibility" TargetName="NavigatorIndicator" Value="Visible"/>
                                <Setter Property="Visibility" TargetName="Background_Selected" Value="Visible"/>
                                <Setter Property="Background" TargetName="NavigatorIndicatorBackground">
                                    <Setter.Value>
                                        <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
                                            <GradientStop Color="White" Offset="0"/>
                                            <GradientStop Color="#FFE4E4E4" Offset="1"/>
                                        </LinearGradientBrush>
                                    </Setter.Value>
                                </Setter>
                            </MultiTrigger>
                            <MultiTrigger>

Then when you select multiple rows you would be able to see the NavigatorIcon path in each row.

I am bit at a loss what exactly you pasted here - was this from a template or a style customized with Blend or... what I am asking for is the surrounding XAML to know where this would have to go.

Thanks,

Hi Christoph,

 

Yes, the code-snippet is part of the extracted template of GridViewRow using Expression Blend.
I am attaching you sample project which demonstrates the proposed solution.

It works - however, one thing needs to be corrected in the sample (when you copy/paste the style):

DataContext="{Binding Source={StaticResource SampleDataSource}}

to

DataContext="{TemplateBinding DataContext}
