覆盖GridView中的默认布尔值过滤WPF，应用自定义布尔过滤器

我有一个GridView与GridViewDataColumn从中我想过滤其中的布尔值，但我不想它写“真”或“假”在过滤器中，但‘VRAI’和‘人造’（法国）覆盖GridView中的默认布尔值过滤WPF，应用自定义布尔过滤器

目前过滤器自动完成（打印‘真’与‘假’，它过滤器），我无法访问布尔值的ToString（）方法。在我的代码后面我加载模型，并设置我的过滤器，如果“Filtersettings”不为空（当用户已保存其参数，很少发生）

我的XAML，我要筛选的列“Intégrée”

<telerik:GridViewColumn MinWidth="33"> 
       <telerik:GridViewColumn.CellTemplate> 
        <DataTemplate> 
         [Some Stuff] 
        </DataTemplate> 
       </telerik:GridViewColumn.CellTemplate> 
      [I deleted some stuff here] 
      </telerik:GridViewColumn> 
         <Style.Triggers> 
          <DataTrigger Binding="{Binding Valide}" Value="False"> 
           <Setter Property="telerik:GridViewCell.Background" Value="{StaticResource ValidationErrorColorBrush}" /> 
          </DataTrigger> 
         </Style.Triggers> 
        </Style> 
       </telerik:GridViewDataColumn.CellStyle> 
      </telerik:GridViewDataColumn> 
      <telerik:GridViewDataColumn Header="Intégrée"     UniqueName="Intégrée" DataMemberBinding="{Binding IsIntegree, Mode=OneWay}"        ShowDistinctFilters="True"/>

你可以尝试使用返回翻译字符串转换器的建议位置：http://www.telerik.com/forums/bool-filter-translation

<telerik:GridViewDataColumn Header="Intégrée" UniqueName="Intégrée" DataMemberBinding="{Binding IsIntegree, Converter={StaticResource MyConverter}}" ShowDistinctFilters="True"> 
    <telerik:GridViewDataColumn.CellTemplate> 
     <DataTemplate> 
      <CheckBox IsChecked="{Binding IsIntegree, Mode=TwoWay}"/> 
     </DataTemplate> 
    </telerik:GridViewDataColumn.CellTemplate> 
</telerik:GridViewDataColumn>

谢谢，我不知道为什么我没有想到这一点早。有效。 –

如果我想使用GridViewDataColumn的“默认”复选框，我该怎么办？这里设置的复选框不同于此（默认情况下会自动创建） –

如果您要自定义过滤器，则不使用默认设置 – mm8

我用了一个转换器。

的XAML

<telerik:GridViewDataColumn Header="Intégrée"     DataMemberBinding="{Binding IsIntegree,Converter={StaticResource BooleanToStringConverter}, Mode=OneWay}"         ShowDistinctFilters="True"> 
       <telerik:GridViewDataColumn.CellTemplate> 
        <DataTemplate> 
         <CheckBox IsChecked="{Binding IsIntegree, Mode=TwoWay}"/> 
        </DataTemplate> 
       </telerik:GridViewDataColumn.CellTemplate> 
      </telerik:GridViewDataColumn>

转换器（别忘了声明它）

public class BooleanToStringConverter : IValueConverter 
{ 
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture) 
    { 
     var val = System.Convert.ToBoolean(value, CultureInfo.InvariantCulture); 
     return val ? "Vrai" : "Faux"; 
    } 

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture) 
    { 
     string temp = value.ToString(); 
     return temp.ToLower().Equals("vrai") ? true : false; 
    } 
}
