本教程講解了如何添加GridControl到wpf項目中并且綁定數據

原文地址Lesson 1 - Add a GridControl to a Project and Bind it to Data | WPF Controls | DevExpress Documentation

1、使用?DevExpress Template Gallery創(chuàng)建一個新的空白mvvm應用程序，這個項目包括了一個視圖模型，設置此視圖模型作為MainView數據上下文

2、按照如下給此項目添加數據庫Blank .NET 6 App with the Northwind Database?.

3、在MainView中添加工具箱選項GridControl:

如果你的項目沒有DevExpress.Wpf.Grid.Core 引用，vs一定顯示如下信息：

此消息提示你必須添加控件引用。

如果你從Nuget訂閱devexpress，進入工具，nuget包管理器，添加DevExpress.Wpf.Grid

4、在Quick Actions菜單中選擇GridControl，點擊綁定到數據源，在Items Source Wizard:

5、選擇數據源：

在GridControl選擇table：

選擇簡單綁定模型，查看如下提示消息關于綁定模型：WPF Data Grid: Bind to Data.

確保CRUD 選項啟動：

在視圖模型選擇視圖模型選項生成數據綁定源碼。在已選擇的View Model中選擇MainViewModel：

6、Items Source Wizard?生成如下代碼：

<dxg:GridControl x:Name="grid" AutoGenerateColumns="AddNew" EnableSmartColumnsGeneration="True" ItemsSource="{Binding ItemsSource}" RestoreStateKeyFieldName="OrderId" RestoreStateOnSourceChange="True"><dxg:GridControl.TotalSummary><dxg:GridSummaryItem Alignment="Right" SummaryType="Count"/></dxg:GridControl.TotalSummary><dxg:GridControl.InputBindings><KeyBinding Command="{Binding View.Commands.DeleteFocusedRow, ElementName=grid}" Key="Delete"/></dxg:GridControl.InputBindings><dxg:GridControl.View><dxg:TableView NewItemRowPosition="Top" ShowUpdateRowButtons="OnCellEditorOpen" ValidateRowCommand="{Binding ValidateRowCommand}" ValidateRowDeletionCommand="{Binding ValidateRowDeletionCommand}" DataSourceRefreshCommand="{Binding DataSourceRefreshCommand}" ShowFixedTotalSummary="True"/></dxg:GridControl.View><dxg:GridColumn FieldName="OrderId" IsSmart="True" ReadOnly="True"/><dxg:GridColumn FieldName="CustomerId" IsSmart="True"/><dxg:GridColumn FieldName="EmployeeId" IsSmart="True"/><dxg:GridColumn FieldName="OrderDate" IsSmart="True"/><dxg:GridColumn FieldName="RequiredDate" IsSmart="True"/><dxg:GridColumn FieldName="ShippedDate" IsSmart="True"/><dxg:GridColumn FieldName="ShipVia" IsSmart="True"/><dxg:GridColumn FieldName="Freight" IsSmart="True"/><dxg:GridColumn FieldName="ShipName" IsSmart="True"/><dxg:GridColumn FieldName="ShipAddress" IsSmart="True"/><dxg:GridColumn FieldName="ShipCity" IsSmart="True"/><dxg:GridColumn FieldName="ShipRegion" IsSmart="True"/><dxg:GridColumn FieldName="ShipPostalCode" IsSmart="True"/><dxg:GridColumn FieldName="ShipCountry" IsSmart="True"/>
</dxg:GridControl>

using DevExpress.Mvvm;
using System;
using WPF_DataGrid_GetStarted.Models;
using DevExpress.Mvvm.DataAnnotations;
using System.Linq;
using System.Collections.Generic;
using DevExpress.Mvvm.Xpf;namespace WPF_DataGrid_GetStarted.ViewModels {public class MainViewModel : ViewModelBase {NorthwindEntities _Context;IList<Order> _ItemsSource;public IList<Order> ItemsSource {get {if (_ItemsSource == null && !DevExpress.Mvvm.ViewModelBase.IsInDesignMode) {_Context = new NorthwindEntities();_ItemsSource = _Context.Orders.ToList();}return _ItemsSource;}}[Command]public void ValidateRow(RowValidationArgs args) {var item = (Order)args.Item;if (args.IsNewItem)_Context.Orders.Add(item);_Context.SaveChanges();}[Command]public void ValidateRowDeletion(ValidateRowDeletionArgs args) {var item = (Order)args.Items.Single();_Context.Orders.Remove(item);_Context.SaveChanges();}[Command]public void DataSourceRefresh(DataSourceRefreshArgs args) {_ItemsSource = null;_Context = null;RaisePropertyChanged(nameof(ItemsSource));}}
}

這個代碼啟動CRUD operations?，為每一個數據源字段生成行，然后顯示所有行數在fixed summary panel.

7、運行如下：
