C# Windows Phone 8.1项目中的ItemsControl

有必要在某些单元格中排列元素，但它们都位于左上角的单元格中。由于行和列的动态创建，这种想法不起作用，但在静态广告中，没有任何变化

请帮忙

XAML

不幸的是，由于容器不在XAML中，因此没有可绑定的内容，因此这将不起作用。您需要做的是将ItemsControl子类化并重写PrepareContainerForItemOverride函数，如下所示：

public class CustomItemsControl : ItemsControl
{
    protected override void PrepareContainerForItemOverride(DependencyObject element, object item)
    {
        base.PrepareContainerForItemOverride(element, item);
        FrameworkElement source = element as FrameworkElement;
        source.SetBinding(Grid.ColumnProperty, new Binding { Path = new PropertyPath("Col") });
        source.SetBinding(Grid.RowProperty, new Binding { Path = new PropertyPath("Row") });
    } 
}

然后将XAML更改为CustomItemsControl，而不是items控件：

        <local:CustomItemsControl x:Name="ItControl" ItemTemplate="{StaticResource DefaultGridItemTemplate}">
               <ItemsControl.ItemsPanel>

<ItemsPanelTemplate>
                    <Grid >
                        <Grid.RowDefinitions>
                            <RowDefinition />
                            <RowDefinition />
                            <RowDefinition/>
                        </Grid.RowDefinitions>
                        <Grid.ColumnDefinitions>
                            <ColumnDefinition />
                            <ColumnDefinition />
                            <ColumnDefinition/>
                        </Grid.ColumnDefinitions>
                    </Grid>
                </ItemsPanelTemplate>
            </ItemsControl.ItemsPanel>
            <!--<ItemsControl.ItemContainerStyle>
                <Style TargetType="ContentPresenter">
                    <Setter Property="Grid.Column" Value="{Binding Col}" />
                    <Setter Property="Grid.Row" Value="{Binding Row}"/>
                </Style>
            </ItemsControl.ItemContainerStyle>-->
        </local:CustomItemsControl>
