wpf devexpress Property Grid创建属性定义

WPF Property Grid控件使用属性定义定义如何做和显示

本教程示范如何绑定WP Property Grid控件到数据和创建属性定义。

执行如下步骤

第一步-创建属性定义

添加PropertyGridControl组件到项目。

打开工具箱在vs，定位到DX.23.1: Data 面板，选择PropertyGridControl工具箱选项，拖动到窗口。

右键点击Property Grid选择Layout | Reset All填充全部窗口：

第二步-创建数据对象

创建数据对象和设置到DataContext

namespace Creating_Definitions {public partial class MainWindow : Window {public MainWindow() {InitializeComponent();DataContext = new Customer() {ID = 1,FirstName = "Nancy",LastName = "Davolio",Gender = Gender.Female,BirthDate = new DateTime(1948, 8, 12),Phone = "7138638137"};}public class Customer {public int ID { get; set; }public string FirstName { get; set; }public string LastName { get; set; }public Gender Gender { get; set; }public DateTime BirthDate { get; set; }public string Phone { get; set; }}public enum Gender { Male, Female }}
}

第三步-绑定Property Grid到Data Object

使用property grid PropertyGridControl.SelectedObject 属性绑定数据

<Windowxmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"xmlns:dxprg="http://schemas.devexpress.com/winfx/2008/xaml/propertygrid" x:Class="PG_lesson1.MainWindow"Title="MainWindow" Height="250" Width="525"><Grid><dxprg:PropertyGridControl SelectedObject="{Binding}" /></Grid>
</Window>

步骤四-创建属性定义

添加属性定义到Property Grid.设置PropertyGridControl.ShowProperties属性ShowPropertiesMode.WithPropertyDefinitions，隐藏未定义属性：

<Windowxmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"xmlns:sys="clr-namespace:System;assembly=mscorlib"xmlns:dxe="http://schemas.devexpress.com/winfx/2008/xaml/editors"xmlns:dxprg="http://schemas.devexpress.com/winfx/2008/xaml/propertygrid" x:Class="PG_lesson1.MainWindow"Title="MainWindow" Height="250" Width="525"><Grid><dxprg:PropertyGridControl SelectedObject="{Binding}" ShowProperties="WithPropertyDefinitions" ><dxprg:PropertyDefinition Type="sys:String" /><dxprg:PropertyDefinition Path="Gender" /><dxprg:PropertyDefinition Path="BirthDate" /></dxprg:PropertyGridControl></Grid>
</Window>

运行程序看到结果
