Datagrid行擴展行silverlight中點擊

Question

我有silverlight應用程序，其中我已經添加了一個切換按鈕來擴大row.at同時我有2個文本框和1個按鈕在同一row.my切換按鈕工作正常，但是當我點擊文本框或按鈕行得到擴大，這不應該發生。行必須展開切換按鈕點擊only.plz指導我呃我錯了。 我的切換按鈕被添加像下面 的.xaml

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

和的.cs代碼如下

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實現如下

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; 

     } 
    } 

我需要什麼條件檢查轉換和ConvertBack.or如何我可以檢查點擊對象是切換按鈕，而不是其他按鈕

Answer 1

您可以在ToggleButton_clicked事件中編寫您爲ToggleButton_Loaded事件編寫的代碼，然後不必檢查單擊哪個按鈕或文本框。

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

而且的.cs代碼

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 
      }); 
    }
