问题描述

如何在 windows store app xaml 中编辑 GRIDVIEW，以便我们可以使其垂直滚动而不是水平滚动.我正在使用 XAML，我们应该使用滚动视图手动创建一个新的用户元素，还是有任何简单的方法可以使用 Windows 商店应用程序来实现这一点.

已解决创建的自定义网格视图模板

solved created custom grid-view template

 public class AdaptableGridView : GridView
    {
        // default itemWidth
        private const double itemWidth = 100.00;
        public double ItemWidth
        {
            get { return (double)GetValue(ItemWidthProperty); }
            set { SetValue(ItemWidthProperty, value); }
        }
        public static readonly DependencyProperty ItemWidthProperty =
            DependencyProperty.Register("ItemWidth", typeof(double), typeof(AdaptableGridView), new PropertyMetadata(itemWidth));
    // default max number of rows or columns
    private const int maxRowsOrColumns = 3;
    public int MaxRowsOrColumns
    {
        get { return (int)GetValue(MaxRowColProperty); }
        set { SetValue(MaxRowColProperty, value); }
    }
    public static readonly DependencyProperty MaxRowColProperty =
        DependencyProperty.Register("MaxRowsOrColumns", typeof(int), typeof(AdaptableGridView), new PropertyMetadata(maxRowsOrColumns));


    public AdaptableGridView()
    {
        this.SizeChanged += MyGridViewSizeChanged;
    }

    private void MyGridViewSizeChanged(object sender, SizeChangedEventArgs e)
    {
        // Calculate the proper max rows or columns based on new size 
        this.MaxRowsOrColumns = this.ItemWidth > 0 ? Convert.ToInt32(Math.Floor(e.NewSize.Width / this.ItemWidth)) : maxRowsOrColumns;
    }
}

xml:

 <local:AdaptableGridView ItemWidth="250" x:Name="tumbview" VerticalAlignment="Stretch" HorizontalAlignment="Stretch"  ItemsSource="{Binding imagelist}" SelectionChanged="GridView_SelectionChanged" Margin="50,0,0,0" >
        <GridView.ItemsPanel>
            <ItemsPanelTemplate>
                <VariableSizedWrapGrid  Orientation="Horizontal" 
                                        ItemWidth="{Binding ElementName=tumbview, Path=ItemWidth}"
                                        MaximumRowsOrColumns="{Binding ElementName=tumbview, Path=MaxRowsOrColumns}"/>
            </ItemsPanelTemplate>
        </GridView.ItemsPanel>
