项目控制在Windows Phone 8.1项目中

在某些单元格中排列元素是必要的,但它们都属于左上角的单元格。由于行和列的动态创建,思想不起作用,但在静态广告中,一切都没有改变。

请帮忙。

XAML

<ItemsControl 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>
</ItemsControl>

C#

public class FilterItem
{
    public int id_node { get; set; }
    public int id_h { get; set; }
    //[MaxLength(50)]
    public string name { get; set; }
    public int Col { get; set; }
    public int Row { get; set; }
}

不幸的是,这将不起作用,因为容器不在XAML中,因此没有可绑定的内容。您要做的是将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,而不是项控件:

        <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>

尝试在方向垂直的StackPanel中添加主ItemsControl。
