ItemsControl - ItemsControl.ItemContainerStyle中的绑定 [英] ItemsControl - Binding in ItemsControl.ItemContainerStyle

问题描述

我试图在ItemsContainerStyle中绑定它似乎没有工作。  这是我的代码：

这是绑定的DataItem：

 public class DataItem 
 {
 public DataItem（string title，string image，string row，string column，string rowSpan，string columnSpan）
 {
 Title = title; 
 Image = image; 
行=行; 
 Column = column; 
 RowSpan = rowSpan; 
 ColumnSpan = columnSpan; 
} 
 
公共字符串标题
 {
 get; 
私人套装; 
} 
公共字符串图片
 {
 get; 
私人套装; 
} 
公共字符串行
 {
 get; 
私人套装; 
} 
公共字符串列
 {
 get; 
私人套装; 
} 
公共字符串RowSpan 
 {
 get; 
私人套装; 
} 
公共字符串ColumnSpan 
 {
 get; 
私人套装; 
} 
 
} 

这是XAML：

< pre class ="prettyprint">< Grid Grid.Row =" 1">
< Grid.Background>
< ImageBrush ImageSource =" /Images/Blue_BkgdGrid1080p.jpg"伸展= QUOT; UniformToFill" />

< / Style>

< / ItemsControl>
<！ - < GridView.ItemTemplate>

< / Grid>

解决方案

< blockquote>实际上整个ItemsContol.ItemContainerStyle都没有被使用.......

I am trying to bind inside the ItemsContainerStyle and it does not seem to be working.  Here is my code:

Here is the DataItem that is being bound:

 public class DataItem
    {
        public DataItem(string title, string image, string row, string column, string rowSpan, string columnSpan)
        {
            Title = title;
            Image = image;
            Row = row;
            Column = column;
            RowSpan = rowSpan;
            ColumnSpan = columnSpan;
        }

        public string Title
        {
            get;
            private set;
        }
        public string Image
        {
            get;
            private set;
        }
        public string Row
        {
            get;
            private set;
        }
        public string Column
        {
            get;
            private set;
        }
        public string RowSpan
        {
            get;
            private set;
        }
        public string ColumnSpan
        {
            get;
            private set;
        }
        
    }

Here is the XAML:

 <Grid Grid.Row="1">
            <Grid.Background>
                <ImageBrush ImageSource="/Images/Blue_BkgdGrid1080p.jpg" Stretch="UniformToFill"/>
            </Grid.Background> 
            <ItemsControl ItemsSource="{Binding Items}">
                <ItemsControl.ItemsPanel>
                    <ItemsPanelTemplate>
                <Grid>
                    <Grid.RowDefinitions>
                        <RowDefinition />
                        <RowDefinition />
                        <RowDefinition />
                    </Grid.RowDefinitions>
                    <Grid.ColumnDefinitions>
                                <ColumnDefinition />
                                <ColumnDefinition />
                                <ColumnDefinition />
                                <ColumnDefinition />
                                <ColumnDefinition />
                    </Grid.ColumnDefinitions>
                </Grid>
                    </ItemsPanelTemplate>
                </ItemsControl.ItemsPanel>
                <ItemsControl.ItemTemplate>
                    <DataTemplate>
                        <Grid Margin="5,0,10,5"  Background="#FF3B3B3B" HorizontalAlignment="Stretch"  VerticalAlignment="Top">
                            <Image Stretch="UniformToFill" Source="{Binding Image}"/>
                        </Grid>
                    </DataTemplate>
                </ItemsControl.ItemTemplate>
                <ItemsControl.ItemContainerStyle>
                    <Style TargetType="ContentPresenter">
                        <Setter Property="Grid.Column" Value="{Binding Column}"/>
                        <Setter Property="Grid.Row" Value="{Binding Row}"/>
                        <Setter Property="Grid.RowSpan" Value="{Binding RowSpan}"/>
                        <Setter Property="Grid.ColumnSpan" Value="{Binding ColumnSpan}"/>
                    </Style>
                </ItemsControl.ItemContainerStyle>

            </ItemsControl>
            <!--<GridView.ItemTemplate>
                <DataTemplate>
                <Grid Margin="5,0,10,5" Height="100" Width="100" Background="#FF3B3B3B" HorizontalAlignment="Stretch"  VerticalAlignment="Top">
                    <Image  Stretch="UniformToFill" Source="{Binding Image}"/>
                </Grid>
                </DataTemplate>
            </GridView.ItemTemplate>-->
        </Grid>

Actually the whole ItemsContol.ItemContainerStyle is not getting used at all.......
