看看基於RelativeSource的綁定的這種用法,如{Binding RelativeSource={RelativeSource AncestorType={x:Type Window}}
。下面是例子:
的XAML:
<DataGrid ItemsSource="{Binding Strings}" AutoGenerateColumns="False" >
<DataGrid.Columns>
<DataGridTemplateColumn Header="String" Width="SizeToCells" IsReadOnly="True">
<DataGridTemplateColumn.CellTemplate>
<DataTemplate DataType="{x:Type soDataGridHeplAttempt:ClicableItemsModel}">
<ListBox HorizontalAlignment="Stretch" VerticalAlignment="Stretch" ItemsSource="{Binding ClickableItems}">
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Horizontal"></StackPanel>
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBox.ItemContainerStyle>
<Style TargetType="ListBoxItem">
<Setter Property="ContentTemplate">
<Setter.Value>
<DataTemplate>
<Button Width="70" Content="{Binding }" Style="{StaticResource ButtonInCellStyle}" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"
Command="{Binding RelativeSource={RelativeSource AncestorType={x:Type Window}}, Path=DataContext.Command}"
CommandParameter="{Binding RelativeSource={RelativeSource Self}, Path=Content}"/>
</DataTemplate>
</Setter.Value>
</Setter>
</Style>
</ListBox.ItemContainerStyle>
</ListBox>
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>
</DataGrid.Columns>
</DataGrid>
視圖模型:
private ICommand _command;
public ObservableCollection<ClicableItemsModel> Strings { get; set; }
public ICommand Command
{
get { return _command ?? (_command = new RelayCommand<object>(MethodOnCommmand)); }
}
private void MethodOnCommmand(object obj)
{
}
型號PU這個模型類中:
public ObservableCollection<String> ClickableItems { get; set; }
關於,
該死的。那麼,我確實知道綁定到一個相對的源代碼,我也試過,但我忘了寫Path = DataContext.MyProperty。我只寫了Path = MyProperty。我的錯。無論如何非常感謝你的幫助。我爲這個問題瘋了。 – hoxplus
