Telerik PropertyDefinition在运行时应用

本文关键字：应用 运行时 PropertyDefinition Telerik | 更新日期: 2023-09-27 17:50:36

我试图使一个RadPropertyGrid，可以采取在运行时的对象，并显示它的属性。我遇到的问题是，这些数据是解耦的，可能有自己的属性定义，需要传递到网格中。

是否有一种方法可以在c#中做到这一点，以便它可以在运行时执行，应用与PropertyGrid无法知道的数据源相关的属性?

Thanks in advance

Telerik PropertyDefinition在运行时应用

使用行为。例如:

在.xaml: 

    <UserControl.Resources>
                <x:Array x:Key="HiddenProperties" Type="sys:String">
                    <sys:String>CanEdit</sys:String>
                    <sys:String>IsEdit</sys:String>
                    <sys:String>DisplayName</sys:String>
                    <sys:String>Changed</sys:String>
                    <sys:String>Changing</sys:String>
                </x:Array>
    </UserControl.Resources>
...
    <telerik:RadPropertyGrid AutoGeneratePropertyDefinitions="True"
                             EditorTemplateSelector="{StaticResource CustomPropertyGridDataTemplateSelector}">
                        <i:Interaction.Behaviors>
                            <extensions:PropertyDefinitionFiltering HiddenProperties="{StaticResource HiddenProperties}" />
                        </i:Interaction.Behaviors>
                    </telerik:RadPropertyGrid>
在cs 

    public class PropertyDefinitionFiltering : Behavior<RadPropertyGrid>
    {
        private static RadPropertyGrid _PropertyGrid;
        #region HiddenProperties
        private static string[] _HiddenProperties;

            _PropertyGrid = propertyGrid;
