매우 강력한 컨트롤 - PropertyGrid

PropertyGrid는 매우 강력한 컨트롤입니다. 이 컨트롤을 속성 설정 패널로 사용하면 UI 표시가 아닌 코드에만 집중하면 됩니다. PropertyGrid는 표시할 적절한 컨트롤을 선택합니다. 기본적으로 변수 유형입니다. 그러나 이는 또한 문제를 야기합니다. 즉, 주로 필요에 따라 컨트롤을 선택할 수 없기 때문에 컨트롤의 사용이 특별히 유연하지 않습니다. 예를 들어 int 변수를 설정하기 위해 Slider 컨트롤을 사용해야 하는 경우 PropertyGrid의 기본값은 템플릿 선택기가 지원되지 않습니다. 주로 IWindowFromService 인터페이스를 사용하여 기본적으로 WinForm 구현을 소개하는 많은 정보를 인터넷에서 찾았지만 WPF에 적합한 데모를 찾지 못했습니다. 나중에 DEVExpress의 공식 데모를 참조하여 데모 기반으로 만들었습니다. WPF 및 DEV 16.2에서 PropertyGrid Demo는 기본적으로 위의 기능을 구현합니다.

이를 달성하려면 이 기사의 핵심 코드이기도 한 DataTemplateSeletor 클래스를 사용자 정의해야 합니다.

1. CustomPropertyGrid 사용자 정의 컨트롤을 만듭니다.

5.将以上的CustomPropertyGrid丢进容器中即可，这里我直接用Mainwindow来演示：

 1 <Window 2     x:Class="PropertyGridDemo.MainWindow" 3     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 4     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 5     xmlns:PropertyGridControl="clr-namespace:PropertyGridDemo.PropertyGridControl" 6     xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 7     xmlns:local="clr-namespace:PropertyGridDemo" 8     xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 9     Title="MainWindow"10     Width="525"11     Height="350"12     WindowState="Maximized"13     mc:Ignorable="d">14     <Grid Margin="10">15         <Grid.ColumnDefinitions>16             <ColumnDefinition Width="259*" />17             <ColumnDefinition Width="259*" />18         </Grid.ColumnDefinitions>19 20         <TextBox21             x:Name="OutputBox"22             Grid.ColumnSpan="1"23             HorizontalScrollBarVisibility="Auto"24             ScrollViewer.CanContentScroll="True" />25         <PropertyGridControl:CustomPropertyGrid x:Name="PropertyGrid" Grid.Column="1" />26     </Grid>27 </Window>

运行示意图：

以上就是自定义PropertyGrid控件的实现代码，本人只实现了简单的Slider和ComboBoxEdit控件，实际上可以根据自己的需要仿照以上的方法扩展到其他控件，这个就看需求了。

个人感觉以上方案还是有所欠缺，主要是自定义控件的模板是由代码生成的，如果可以直接从资源文件中读取将会更加方便，不过本人尝试了几次并不能成功的实现数据的绑定，如果大家有什么好的解决方案欢迎在评论区留言，也欢迎大家在评论区进行讨论。
