在GridView WPF中覆盖默认布尔过滤，应用自定义布尔过滤器 [英] Override default Boolean Filtering in GridView WPF, Apply Custom bool filter

问题描述

我有一个GridView与GridViewDataColumn，我想从中过滤布尔值，但我不想写它True或False在过滤器中，但Vrai和Faux（法语）

（打印True和False并过滤），我无法访问布尔的ToString（）方法。
在我的Code后面加载模型并设置我的过滤器，如果Filtersettings不为null（当用户保存了它的参数，很少发生）

我的XAML，我想过滤列Intégrée

 < telerik：GridViewColumn MinWidth = 33 > 
< telerik：GridViewColumn.CellTemplate> 
< DataTemplate> 
 [某些东西] 
< / DataTemplate> 
< / telerik：GridViewColumn.CellTemplate> 
 [我在这里删除了一些东西] 
< / telerik：GridViewColumn> 
< Style.Triggers> 
< DataTrigger Binding ={Binding Valide}Value =False> 
< Setter Property =telerik：GridViewCell.BackgroundValue ={StaticResource ValidationErrorColorBrush}/> 
< / DataTrigger> 
 < / style> 
< / telerik：GridViewDataColumn.CellStyle> 
< / telerik：GridViewDataColumn> 
< telerik：GridViewDataColumn Header =IntégréeUniqueName =IntégréeDataMemberBinding ={Binding IsIntegree，Mode = OneWay}ShowDistinctFilters =True/> 
  

我的代码隐藏

  public partial class DemandeCotationListeView：UserControl 
 {
 public DemandeCotationListeView（）
 {
 InitializeComponent（）; 
 DemandeCotationListeViewModel demandeCotationViewModel = new DemandeCotationListeViewModel（）; 
 DataContext = demandeCotationViewModel; 
 
 //应用个性化过滤器
 for（int cpt = 2; cpt< GridView.Columns.Count; cpt ++）
 {
 GridView.Columns [cpt] .FilteringControl = new PersonalizedFilteringControl（GridView.Columns [cpt]）; 
} 
 
 //这里我试图访问过滤器
 Telerik.Windows.Controls.GridViewColumn isIntegreeColumn = this.GridView.Columns [Intégrée]; 
 IColumnFilterDescriptor integreeFilter = isIntegreeColumn.ColumnFilterDescriptor; 
 //我不能添加一个字符串，而是一个对象
 // integreeFilter.DistinctFilter.AddDistinctValue（Faux）; 
 
 
 private void GridView_Loaded（object sender，RoutedEventArgs e）
 {
 try 
 {
 IList< FilterSetting> filtersSettings = JsonConvert.DeserializeObject< IList< FilterSetting>>（Settings.Default.DemandeCotationViewFilterConfig）; 
 //因为filterSettings总是为空

你可以尝试使用一个转换器，返回翻译后的字符串，如下所示： http：// www .telerik.com / forums / bool-filter-translation

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




I have a GridView with GridViewDataColumn from which I want to filter on the boolean values in it but I don't want it to write "True" or "False" in the filter but "Vrai" and "Faux" (french)

Currently the filter is done automatically (prints "True" and "False" and it filters), I can't access the ToString() method of the boolean. In my Code behind I load the model and setup my filters if "Filtersettings" isn't null (when user has saved its parameters, happens rarely)

My XAML, I want to filter the column "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"/>

解决方案

You could try to use a converter that returns the translated strings as suggested here: 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>
