绑定到附加属性Grid.Row和Grid.Column [英] Binding to attached property Grid.Row and Grid.Column

问题描述

我需要绑定到一个附加的属性，如Grid.Row和Grid.Column，但似乎它不工作。
我试过多个选项，但没有运气，下面是xaml的细节。

I need to bind to an attached properties like Grid.Row and Grid.Column but it seems that it is not working. I tried multiple options but no luck , below are the xaml details.

 <Grid>
                <Grid>
                    <Grid vm:GridHelper.RowCount="{Binding RowCount}"
                          vm:GridHelper.ColumnCount="2" />
                    <ItemsControl ItemsSource="{Binding ControlCollection}">
                        <ItemsControl.ItemContainerStyle>
                            <Style>
                                <Setter Property="Grid.Row" Value="{Binding Path=Row}" />
                                <Setter Property="Grid.Column" Value="{Binding Path=Column}" />
                            </Style>
                        </ItemsControl.ItemContainerStyle>
                        <ItemsControl.ItemTemplate>
                            <DataTemplate>
                                <TextBlock Text="{Binding Text}" Margin="5,5,20,5" FontSize="12" 
                                           TextWrapping="WrapWithOverflow"
                                           Foreground="#AEAEAE" FontFamily="Tahoma" VerticalAlignment="Center"/>
                            </DataTemplate>
                        </ItemsControl.ItemTemplate>

                    </ItemsControl>
                </Grid>

推荐答案

Grid.Row 和 Grid.Column setters在ItemContainerStyle有效，你必须使用一个Grid作为 ItemsPanel

In order to make the Grid.Row and Grid.Column setters in the ItemContainerStyle effective, you have to use a Grid as ItemsPanel of the ItemsControl:

<ItemsControl ItemsSource="{Binding ControlCollection}">
    <ItemsControl.ItemsPanel>
        <ItemsPanelTemplate>
            <Grid>
                <Grid.RowDefinitions>
                    ...
                </Grid.RowDefinitions>
                <Grid.ColumnDefinitions>
                    ...
                </Grid.ColumnDefinitions>
            </Grid>
        </ItemsPanelTemplate>
    </ItemsControl.ItemsPanel>
    ...
</ItemsControl>
