以编程方式添加数据透视表项

Question

我想在Pivot Control中显示照片列表,所以我有这个xaml

<Grid x:Name="LayoutRoot" Background="Transparent">
    <controls:Pivot x:Name="DiaporamaPivot">
    </controls:Pivot>
</Grid>

在我做的背后的代码中:

    public Diaporama()
    {
        InitializeComponent();

        PivotItem p = new PivotItem();
        Image     i = new Image();

        i.Source = new BitmapImage(new Uri("/image.jpg", UriKind.Relative));
        p.Margin = new Thickness(0, -10, 0, -2);

        DiaporamaPivot.Items.Add(i);
    }

知道为什么我得到一个例外

Answer 1

你正在添加i(Image)Pivot.相反,添加i到p然后添加p(PivotItem)到Pivot.

public Diaporama()
{
    InitializeComponent();

    PivotItem p = new PivotItem();
    Image     i = new Image();

    i.Source = new BitmapImage(new Uri("/image.jpg", UriKind.Relative));
    p.Margin = new Thickness(0, -10, 0, -2);

    p.Content = i;
    DiaporamaPivot.Items.Add(p);
}
