Scrollviewer问题wpf

Question

我在列表框中显示图像.我已将此列表框放在scrollviewer中.我使用两个重复按钮来移动列表框项目.我使用datacontext绑定列表框.

问题:

如果我使用按钮移动图像并单击lisbox中的图像,它将移动到初始位置.

码:

   <RepeatButton Click="rbtnLeft_Click" Name="rbtnLeft" Width="30" Height="30">
                <Image Source="Images/GeneralImages/search_right_arrow.jpg"></Image>
            </RepeatButton>
            <Grid  x:Name="grid"  Width="666" HorizontalAlignment="Left">
                <ScrollViewer Grid.Row="1" Name="svGame"
                VerticalScrollBarVisibility="Hidden" 
                HorizontalScrollBarVisibility="Hidden"  >
                    <ListBox ClipToBounds="True" Name="lbGameImage" Width="Auto" SelectionChanged="lbGameImage_SelectionChanged" ItemsSource="{Binding}"   ItemsPanel="{DynamicResource iptListBox}" ItemContainerStyle="{DynamicResource ListBoxItemStyle}"
              ScrollViewer.VerticalScrollBarVisibility="Hidden" 
              ScrollViewer.HorizontalScrollBarVisibility="Hidden"/>
                </ScrollViewer>                                       
            </Grid>
            <RepeatButton Click="rbtnRight_Click" Name="rbtnRight" Width="30" Height="30">
                <Image Source="Images/GeneralImages/search_left_arrow.jpg"></Image>
            </RepeatButton>

c#代码:

private void rbtnLeft_Click(object sender, RoutedEventArgs e)
    {
        svGame.ScrollToHorizontalOffset(svGame.HorizontalOffset + 5);
    }

    private void rbtnRight_Click(object sender, RoutedEventArgs e)
    {
        svGame.ScrollToHorizontalOffset(svGame.HorizontalOffset - 5);
    }

问题是ListBox认为它拥有ScrollViewer,因此每当选择更改时,它会将偏移量设置回原来的值.ScrollViewer.CanContentScroll="False"在ListBox中设置以防止这种情况.
