Datagrid行扩展行silverlight中点击

Question

我有silverlight应用程序，其中我已经添加了一个切换按钮来扩大row.at同时我有2个文本框和1个按钮在同一row.my切换按钮工作正常，但是当我点击文本框或按钮行得到扩大，这不应该发生。行必须展开切换按钮点击only.plz指导我呃我错了。 我的切换按钮被添加像下面 的.xaml

<data:DataGridTemplateColumn.CellTemplate> 
     <DataTemplate> 
      <ToggleButton Style="{StaticResource PlusMinusToggleButtonStyle}" Loaded="ToggleButton_Loaded" /> 
     </DataTemplate> 
</data:DataGridTemplateColumn.CellTemplate> 

和的.cs代码如下

private void ToggleButton_Loaded(object sender, RoutedEventArgs e) 
     { 
      ToggleButton button = sender as ToggleButton; 
      DataGridRow row = button.FindAncestor<DataGridRow>(); //Custom Extension 
      row.SetBinding(DataGridRow.DetailsVisibilityProperty, new System.Windows.Data.Binding() 
      { 
       Source = button, 
       Path = new PropertyPath("IsChecked"), 
       Converter = new VisibilityConverter(), 
       Mode = BindingMode.TwoWay 
      }); 
    } 

和接口的IValueConverter实现如下

public class VisibilityConverter : IValueConverter 
    { 

     public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) 
     { 
      if ((bool)value) return Visibility.Visible; 
      else return Visibility.Collapsed; 
     } 

     public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) 
     { 
      if ((Visibility)value == Visibility.Visible) 
       return true; 
      else return false; 

     } 
    } 

我需要什么条件检查转换和ConvertBack.or如何我可以检查点击对象是切换按钮，而不是其他按钮

Answer 1

您可以在ToggleButton_clicked事件中编写您为ToggleButton_Loaded事件编写的代码，然后不必检查单击哪个按钮或文本框。

<ToggleButton Style="{StaticResource PlusMinusToggleButtonStyle}" Click="ToggleButton_Clicked" /> 

而且的.cs代码

private void ToggleButton_Clicked(object sender, RoutedEventArgs e) 
     { 
      ToggleButton button = sender as ToggleButton; 
      DataGridRow row = button.FindAncestor<DataGridRow>(); //Custom Extension 
      row.SetBinding(DataGridRow.DetailsVisibilityProperty, new System.Windows.Data.Binding() 
      { 
       Source = button, 
       Path = new PropertyPath("IsChecked"), 
       Converter = new VisibilityConverter(), 
       Mode = BindingMode.TwoWay 
      }); 
    }
