如何绑定到ItemsControl中的DataTemplate中的索引silverlight

Question

我有一个使用ItemsControl的Silverlight应用程序。里面说的ItemsControl的我有一个类似如下定义一个DataTemplate：

XAML

<ItemsControl Grid.Row="1" Grid.ColumnSpan="5" x:Name="dgOdds"> 
       <ItemsControl.ItemTemplate> 
        <DataTemplate> 
         <Grid x:Name="gRoot"> 
          <Grid.ColumnDefinitions> 
           <ColumnDefinition Width="200"/> 
           <ColumnDefinition Width="200"/> 
           <ColumnDefinition Width="200"/> 
          </Grid.ColumnDefinitions> 

          <TextBox x:Name="OF1" Grid.Column="0" Text="{Binding OddFactor, Mode=TwoWay}" FontWeight="Bold" VerticalAlignment="Center" HorizontalContentAlignment="Center"/> 
          <TextBox x:Name="OFX" Grid.Column="1" Text="{Binding OddFactor, Mode=TwoWay}" FontWeight="Bold" VerticalAlignment="Center" HorizontalContentAlignment="Center"/> 
          <TextBox x:Name="OF2" Grid.Column="2" Text="{Binding OddFactor, Mode=TwoWay}" FontWeight="Bold" VerticalAlignment="Center" HorizontalContentAlignment="Center"/> 
         </Grid> 
        </DataTemplate> 
       </ItemsControl.ItemTemplate> 
      </ItemsControl> 

我有对象的列表：

C＃

ObservableCollection<TestObj> SomeList = new ObservableCollection<TestObj>; 
SomeList.Add(new TestObj(){ OddType = 1, OddFakctor = 1.1 }); 
SomeList.Add(new TestObj(){ OddType = 2, OddFakctor = 2.2 }); 
SomeList.Add(new TestObj(){ OddType = 3, OddFakctor = 3.3 }); 
this.dgOdds.ItemsSource = this.Collection; 

TestObj类如下：

public class TestObj 
    { 
     public double OddType { get; set;} 
     public double OddFakctor { get; set; } 
    } 

我想在我的控制是这样显示的属性：

If OddType equal 1, than show in TextBox x:Name="OF1", 
if OddType equal 2, than show in TextBox x:Name="OFX", 
if OddType equal 3, than show in TextBox x:Name="OF3" 

如何做到这一点？

Answer 1

因为你想显示OddType等于1或2或3，你可以只有一个文本块。 就像选择了1，那么TextBox中的一个将具有OF1，而其他的将为空。

private double _oddfactor; 
public double OddFakctor 
{ 
     get 
     { 
      return _oddfactor; 
     } 
     set 
     { 
      _oddfactor = value; 
      OnPropertyChanged(() => OddFakctor); 
     } 
    } 

如果在这里-u更新的_OddFakctor，它将与笏ü[R传递到_oddfactor
