Hi,
我认为你的代码是没有问题的，我并没有找到有什么问题可能还需要其他的代码比如getdata（）里面的代码，如果你觉得贴在论坛上会有隐私问题的话你可以把有问题的工程删掉一些设计隐私的数据之后用邮件发给我 v-axue at microsoft.com
下面是我用来测试的代码，我并没有发现问题，我在上面绑定了一个Textblock来查看HorizontalOffset的值。
XAML:
<Grid Background="{StaticResource ApplicationPageBackgroundThemeBrush}">
<Grid.RowDefinitions>
<RowDefinition Height="100" />
<RowDefinition />
</Grid.RowDefinitions>
<TextBlock Name="tb" />
<GridView Grid.Row="1" Name="gv">
<GridView.ItemContainerStyle>
<Style TargetType="GridViewItem">
<Setter Property="Height" Value="400" />
<Setter Property="Width" Value="400" />
</Style>
</GridView.ItemContainerStyle>
<GridView.Items>
<TextBlock Text="111111" />
<TextBlock Text="111111" />
<TextBlock Text="111111" />
<TextBlock Text="111111" />
<TextBlock Text="111111" />
<TextBlock Text="111111" />
<TextBlock Text="111111" />
<TextBlock Text="111111" />
<TextBlock Text="111111" />
<TextBlock Text="111111" />
<TextBlock Text="111111" />
<TextBlock Text="111111" />
<TextBlock Text="111111" />
<TextBlock Text="111111" />
<TextBlock Text="111111" />
<TextBlock Text="111111" />
</GridView.Items>
</GridView>
</Grid>
C#：
public static T FindVisualChildByName<T>(DependencyObject parent, string name) where T : DependencyObject
{
for (int i = 0; i < VisualTreeHelper.GetChildrenCount(parent); i++)
{
var child = VisualTreeHelper.GetChild(parent, i);
string controlName = child.GetValue(Control.NameProperty) as string;
if (controlName == name)
{
return child as T;
}
else
{
T result = FindVisualChildByName<T>(child, name);
if (result != null)
return result;
}
}
return null;
}
private void Page_Loaded_1(object sender, RoutedEventArgs e)
{
ScrollViewer sv = FindVisualChildByName<ScrollViewer>(this.gv, "ScrollViewer");
this.tb.SetBinding(TextBlock.TextProperty, new Binding() { Path = new PropertyPath("HorizontalOffset"), Source = sv });
sv.ScrollToHorizontalOffset(3);
}
