我有一个绑定到项目列表的 ItemsControl。这些项目具有名称和值属性。value 属性属于 Object 类型，以允许使用不同的数据类型。为了正确显示 value 属性，我将 ContentPresenter 与我可能使用的每种数据类型的数据模板一起使用。

  <ItemsControl ItemsSource="{Binding Items}">
    <ItemsControl.ItemTemplate>
        <DataTemplate>
            <Grid>
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="*"/>
                    <ColumnDefinition Width="Auto" />
                    <ColumnDefinition Width="*"/>
                </Grid.ColumnDefinitions>

                <TextBlock Text="{Binding Path=Name}"/>

                <GridSplitter Width="1" 
                              Grid.RowSpan="4" Grid.Column="1" 
                              HorizontalAlignment="Stretch" VerticalAlignment="Stretch"/>

                <ContentPresenter Grid.Column="2" Content="{Binding Value}">
                    <ContentPresenter.Resources>
                        <DataTemplate DataType="{x:Type System:String}">
                            <TextBox Text="{Binding Path=Content, RelativeSource={RelativeSource AncestorType={x:Type ContentPresenter}}}" 
                                     BorderThickness="0"/>
                        </DataTemplate>
                        <DataTemplate DataType="{x:Type System:Int32}">
                            <TextBox Text="{Binding Path=Content, RelativeSource={RelativeSource AncestorType={x:Type ContentPresenter}}}" 
                                     TextAlignment="Right"
                                     BorderThickness="0"/>
                        </DataTemplate>
                        <DataTemplate DataType="{x:Type System:Double}">
                            <TextBox Text="{Binding Path=Content, RelativeSource={RelativeSource AncestorType={x:Type ContentPresenter}}}" 
                                     TextAlignment="Right"
                                     BorderThickness="0"/>
                        </DataTemplate>
                        <DataTemplate DataType="{x:Type System:Boolean}">
                            <CheckBox IsChecked="{Binding Path=Content, RelativeSource={RelativeSource …

我正在尝试制作 PropertyGrid 自定义控件。PropertyGrid 与 Visual Studio 中使用的 PropertyGrid 非常相似。我尝试使用扩展 WPF 工具包的 PropertyGrid，但您必须使用属性指定属性的类别，并且我们需要在运行时更改类别。据我所知，这对于属性来说是不可能的。

所以我自己制作PropertyGrid。到目前为止，这是我的代码：

Generic.xaml：

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                    xmlns:local="clr-namespace:HomeMadePropertyGrid"
                    xmlns:System="clr-namespace:System;assembly=mscorlib">

    <BooleanToVisibilityConverter x:Key="BoolToVisConverter"></BooleanToVisibilityConverter>
    <SolidColorBrush x:Key="GlyphBrush" Color="#444" />
    <ControlTemplate x:Key="toggleButtonTemplate" TargetType="ToggleButton">
        <Grid Width="15" Height="13" Background="Transparent">
            <Path x:Name="ExpandPath" Fill="{StaticResource GlyphBrush}" Data="M 4 0 L 8 4 L 4 8 Z" HorizontalAlignment="Left" VerticalAlignment="Center" Margin="1,1,1,1" />
        </Grid>
        <ControlTemplate.Triggers>
            <Trigger Property="IsChecked" Value="True">
                <Setter Property="Data" TargetName="ExpandPath" Value="M 0 4 L 8 4 L 4 8 Z"/>
            </Trigger>
        </ControlTemplate.Triggers>
    </ControlTemplate>
    <Style x:Key="toggleButtonStyle" TargetType="ToggleButton">
        <Setter Property="Template" Value="{StaticResource toggleButtonTemplate}" />
    </Style> …

问题

我需要清理从用户输入到有效属性名称的字符串集合。

语境

We have a DataGrid that works with runtime generated classes. These classes are generated based on some parameters. Parameter names are converted into Properties. Some of these parameter names are from user input. We implemented this and it all seemed to work great. Our logic to sanitizing strings was to only allow numbers and letters and convert the rest to an X.

const string regexPattern = @"[^a-zA-Z0-9]";
return ("X" + Regex.Replace(input, regexPattern, "X")); //prefix with X in …
