Question

Goal:
Need to make selection of a single row included button in the listview.

Problem:
Don’t know how to make a single selection in the listview when you are clicking on the button that is located inside of listview. In a simple explanation, when clicking on the button, no selection will be applied in the listview’s row

It would be great if selection is applied before entering button’s method cuz i need to grab information from the single selection of the listview that should be sent to business logic.

Answer 1

You should not need to select the ListViewItem, you can get your dataobject from the DataContext of the Button and you don’t need the data from other rows since you wanted a single selection anyway.

In the event-handler:

var data = (sender as FrameworkElement).DataContext as MyData;

(On a side note, that being said, do you need selection at all? If not use an ItemsControl)

To make the ListViewItem select itself if the button is clicked you can use a ItemContainerStyle like this:

<ListView.ItemContainerStyle>
    <Style TargetType="{x:Type ListViewItem}">
        <Setter Property="IsSelected"
                Value="{Binding RelativeSource={RelativeSource Self}, Path=IsKeyboardFocusWithin, Mode=OneWay}" />
    </Style>
</ListView.ItemContainerStyle>

Here is an alternative using an animation which preserves the selected item after the ListView looses focus (only works with ListView.SelectionMode being Single as it does not seem to be possible to clear the previous selection using an animation):

<Style TargetType="{x:Type ListViewItem}">
    <Style.Triggers>
        <DataTrigger
                Binding="{Binding RelativeSource={RelativeSource Self}, Path=IsKeyboardFocusWithin, Mode=OneWay}"
                Value="True">
            <DataTrigger.EnterActions>
                <BeginStoryboard>
                    <Storyboard>
                        <BooleanAnimationUsingKeyFrames Storyboard.TargetProperty="IsSelected">
                            <DiscreteBooleanKeyFrame KeyTime="0" Value="True" />
                        </BooleanAnimationUsingKeyFrames>
                    </Storyboard>
                </BeginStoryboard>
            </DataTrigger.EnterActions>
        </DataTrigger>
    </Style.Triggers>
</Style>
