                        <Grid.RowDefinitions>
                            <RowDefinition/>

                        </Grid.RowDefinitions>

                                <Image Grid.Row="0" x:Name="image" Source="{Binding avatar}" Width="50" Height="80"/>
                                <TextBlock Grid.Row="1" x:Name="nom" Text="{Binding prenom}" VerticalAlignment="Center"/>
                    </Grid>
                    </Border>
                </DataTemplate>
            </ListBox.ItemTemplate>
        </ListBox>
    </Grid>
</UserControl>

推荐答案

使用Button代替Image并覆盖Button的模板以使其具有外观，，以便您获得可点击的图像.

Use Button in place of Image and override template of Button to give it an Image look, so that you can have clickable image.

<Button Grid.Row="0" Width="50" Height="80">
    <Button.Template>
        <ControlTemplate>
            <Image x:Name="image" Source="{Binding avatar}"/>
        </ControlTemplate>
    </Button.Template>
</Button>

如果使用的是MVVM，则可以将Command与按钮绑定，或者如果要在后面的代码中执行操作，则可以挂接Button的Click事件以确定要单击的图像.

If you are using MVVM, you can bind Command with button OR if want to do in code behind you can hook Click event of button to determine which image is clicked on.
