C# Windows Phone 8.1 Pivot中的两列Gridview

在Windows Phone 8.1应用程序中显示两列gridview时遇到问题

这是我的预期结果：

在回顾处理之后，我生成了以下代码：

 <Canvas>

    <Grid Tapped="Grid_Tapped">
        <Grid.RowDefinitions>
            <RowDefinition Height="93*"/>
            <RowDefinition Height="35*"/>
        </Grid.RowDefinitions>


        <Pivot  Name="centerPivot" Margin="0,109,0,0" Grid.Row="0" Grid.RowSpan="2" Canvas.ZIndex="2" Tapped="centerPivot_Tapped">
            <PivotItem Name="FindPivotItem" Margin="11,10,13,0.333">
                <PivotItem.Header>
                    <Grid>
                        <TextBlock Name="FindTitle" FontSize="31" Text="Store Finds" Foreground="#FF878787" FontFamily="Global User Interface" />
                    </Grid>
                </PivotItem.Header>
                <!--<GridView 
                  ScrollViewer.VerticalScrollBarVisibility="Visible" 

                  ItemTemplate="{Binding ManyListingStyle}"

                  Grid.Row="1" 
                  VerticalAlignment="Top" 
                  VerticalContentAlignment="Top" Height="450" Margin="0,0,-0.167,0" 
             />-->

                <GridView 

                Name="GridGridView"

                ItemsSource="{Binding}"
                Grid.Row="4"
                IsSwipeEnabled="True" 
                SelectionMode="Single"

                ScrollViewer.VerticalScrollMode="Enabled" Margin="0,0,0,0.333" HorizontalAlignment="Left"
                >
                    <GridView.ItemsPanel>
                        <ItemsPanelTemplate>
                            <WrapGrid Orientation="Vertical"
                                  MaximumRowsOrColumns="3"

                                  >

                            </WrapGrid>
                        </ItemsPanelTemplate>
                    </GridView.ItemsPanel>
                    <GridView.ItemTemplate>
                        <DataTemplate>

为什么我看不到结果？

我所做的：

• 当您想将项目放入时，请使用

  Orientation=Horizontal

• 我将项目的网格宽度更改为180，当它为190时，项目垂直放置，因为在我的屏幕上宽度太小
• 我已将MaximumRowsOrColumns更改为2，因为您需要两个水平项
• 我已经删除了ScrollViewer信息-它由GridView自动应用
• 我已经移除了画布，所以GridView知道它有多少位置

代码如下所示：

结果是：

---

delete width=“378”会起作用，但似乎变化不大。UI看起来完全一样，但仍然没有滚动。好的，我会尝试一些方法，如果有任何方法可行，请告诉您您只需要网格中的两列？是的，两列中都设置了自定义矩形数据模板。与您在第一张图像中看到的相同。此答案不会水平呈现项目。相反，它会先垂直渲染它们（这样当渲染6个元素时，只显示1,2,4,5。您必须滚动才能看到3,6）。查看上述问题中我的视觉效果，了解有关我要查找的内容的更多信息。@JcKelley我已重新生成答案litte-现在使用GridView的ScrollViewer，项目水平排列。您必须稍微调整项目的网格宽度和边距，才能正确定位元素。

//Create new Fake Listings
        var listings = new List<Listing>();

        var fakelisting1 = new Listing();
        fakelisting1.title = "Brand new Product!";
        fakelisting1.price = "9.99";
        listings.Add(fakelisting1);

        var fakelisting2 = new Listing();
        fakelisting2.title = "Here is the new Product!";
        fakelisting2.price = "19.99";
        listings.Add(fakelisting2);

        var fakelisting3 = new Listing();
        fakelisting3.title = "Here is the new 2Product!";
        fakelisting3.price = "29.99";
        listings.Add(fakelisting3);

        var fakelisting4 = new Listing();
        fakelisting4.title = "Here is the new 3Product!";
        fakelisting4.price = "39.99";
        listings.Add(fakelisting4);

        var fakelisting5 = new Listing();
        fakelisting5.title = "Here is the new 4Product!";
        fakelisting5.price = "49.99";
        listings.Add(fakelisting5);

        var fakelisting6 = new Listing();
        fakelisting6.title = "Here is the new 5Product!";
        fakelisting6.price = "59.99";
        listings.Add(fakelisting6);

        var fakelisting7 = new Listing();
        fakelisting7.title = "Here is the new 6Product!";
        fakelisting7.price = "49.99";
        listings.Add(fakelisting7);

        var fakelisting8 = new Listing();
        fakelisting8.title = "Here is the new 7Product!";
        fakelisting8.price = "49.99";
        listings.Add(fakelisting8);

        GridGridView.DataContext = listings;
