新增一個數(shù)據(jù)模型

用Customer類的集合創(chuàng)建一個數(shù)據(jù)模型：

DataModel.cs

using System;
using System.Collections.ObjectModel;

namespace BindToLocalCollection {
public class Customer {
public string Name { get; set; }
public string City { get; set; }
public int Visits { get; set; }
public DateTime? Birthday { get; set; }
}
public class CustomerDataModel {
public ObservableCollection<Customer> GetCustomers() {
ObservableCollection<Customer> people = new ObservableCollection<Customer>();
people.Add(new Customer() { Name = "Gregory S. Price", City = "Hong Kong", Visits = 4, Birthday = new DateTime(1980, 1, 1) });
people.Add(new Customer() { Name = "Irma R. Marshall", City = "Madrid", Visits = 2, Birthday = new DateTime(1966, 4, 15) });
people.Add(new Customer() { Name = "John C. Powell", City = "Los Angeles", Visits = 6, Birthday = new DateTime(1982, 3, 11) });
people.Add(new Customer() { Name = "Christian P. Laclair", City = "London", Visits = 11, Birthday = new DateTime(1977, 12, 5) });
people.Add(new Customer() { Name = "Karen J. Kelly", City = "Hong Kong", Visits = 8, Birthday = new DateTime(1956, 9, 5) });
people.Add(new Customer() { Name = "Brian C. Cowling", City = "Los Angeles", Visits = 5, Birthday = new DateTime(1990, 2, 27) });
people.Add(new Customer() { Name = "Thomas C. Dawson", City = "Madrid", Visits = 21, Birthday = new DateTime(1965, 5, 5) });
people.Add(new Customer() { Name = "Angel M. Wilson", City = "Los Angeles", Visits = 8, Birthday = new DateTime(1987, 11, 9) });
people.Add(new Customer() { Name = "Winston C. Smith", City = "London", Visits = 1, Birthday = new DateTime(1949, 6, 18) });
people.Add(new Customer() { Name = "Harold S. Brandes", City = "Bangkok", Visits = 3, Birthday = new DateTime(1989, 1, 8) });
people.Add(new Customer() { Name = "Michael S. Blevins", City = "Hong Kong", Visits = 4, Birthday = new DateTime(1972, 9, 14) });
people.Add(new Customer() { Name = "Jan K. Sisk", City = "Bangkok", Visits = 6, Birthday = new DateTime(1989, 5, 7) });
people.Add(new Customer() { Name = "Sidney L. Holder", City = "London", Visits = 19, Birthday = new DateTime(1971, 10, 3) });
return people;
}
}
}

DataModel.vb

Imports System
Imports System.Collections.ObjectModel

Namespace BindToLocalCollection
Public Class Customer
Public Property Name As String
Public Property City As String
Public Property Visits As Integer
Public Property Birthday As DateTime?
End Class

Public Class CustomerDataModel
Public Function GetCustomers() As ObservableCollection(Of Customer)
Dim people As ObservableCollection(Of Customer) = New ObservableCollection(Of Customer)()
people.Add(New Customer() With { .Name = "Gregory S. Price", .City = "Hong Kong", .Visits = 4, .Birthday = New DateTime(1980, 1, 1) })
people.Add(New Customer() With { .Name = "Irma R. Marshall", .City = "Madrid", .Visits = 2, .Birthday = New DateTime(1966, 4, 15) })
people.Add(New Customer() With { .Name = "John C. Powell", .City = "Los Angeles", .Visits = 6, .Birthday = New DateTime(1982, 3, 11) })
people.Add(New Customer() With { .Name = "Christian P. Laclair", .City = "London", .Visits = 11, .Birthday = New DateTime(1977, 12, 5) })
people.Add(New Customer() With { .Name = "Karen J. Kelly", .City = "Hong Kong", .Visits = 8, .Birthday = New DateTime(1956, 9, 5) })
people.Add(New Customer() With { .Name = "Brian C. Cowling", .City = "Los Angeles", .Visits = 5, .Birthday = New DateTime(1990, 2, 27) })
people.Add(New Customer() With { .Name = "Thomas C. Dawson", .City = "Madrid", .Visits = 21, .Birthday = New DateTime(1965, 5, 5) })
people.Add(New Customer() With { .Name = "Angel M. Wilson", .City = "Los Angeles", .Visits = 8, .Birthday = New DateTime(1987, 11, 9) })
people.Add(New Customer() With { .Name = "Winston C. Smith", .City = "London", .Visits = 1, .Birthday = New DateTime(1949, 6, 18) })
people.Add(New Customer() With { .Name = "Harold S. Brandes", .City = "Bangkok", .Visits = 3, .Birthday = New DateTime(1989, 1, 8) })
people.Add(New Customer() With { .Name = "Michael S. Blevins", .City = "Hong Kong", .Visits = 4, .Birthday = New DateTime(1972, 9, 14) })
people.Add(New Customer() With { .Name = "Jan K. Sisk", .City = "Bangkok", .Visits = 6, .Birthday = New DateTime(1989, 5, 7) })
people.Add(New Customer() With { .Name = "Sidney L. Holder", .City = "London", .Visits = 19, .Birthday = New DateTime(1971, 10, 3) })
Return people
End Function
End Class
End Namespace

新增一個視圖模型

創(chuàng)建一個從CustomerDataModel接收數(shù)據(jù)的視圖模型類：

ViewModel.cs

using DevExpress.Mvvm;
using System.Collections.ObjectModel;

namespace BindToLocalCollection {
public class ViewModel : ViewModelBase {
public ViewModel() {
Source = CustomerDataModel.GetCustomers();
}
public ObservableCollection<Customer> Source { get; }
}
}

ViewModel.vb

Imports DevExpress.Mvvm
Imports System.Collections.ObjectModel

Namespace BindToLocalCollection
Public Class ViewModel
Inherits ViewModelBase

Public Sub New()
Source = CustomerDataModel.GetCustomers()
End Sub

Public ReadOnly Property Source As ObservableCollection(Of Customer)
End Class
End Namespace

將GridControl綁定到數(shù)據(jù)

1. 構(gòu)建解決方案，使ViewModel類在窗口的Quick Actions中可見。

2. 打開窗口的Quick Actions并指定窗口的數(shù)據(jù)上下文：

您也可以在代碼中定義窗口的數(shù)據(jù)上下文：

XAML

<Window
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:BindToLocalCollection"
xmlns:dxg="http://schemas.devexpress.com/winfx/2008/xaml/grid"
x:Class="BindToLocalCollection.MainWindow"
mc:Ignorable="d"
Title="MainWindow" Height="450" Width="800">
<Window.DataContext>
<local:ViewModel/>
</Window.DataContext>
<Grid>
<dxg:GridControl AutoGenerateColumns="AddNew"
EnableSmartColumnsGeneration="True">
<dxg:GridControl.View>
<dxg:TableView/>
</dxg:GridControl.View>
</dxg:GridControl>
</Grid>
</Window>

3. 打開GridControl的Quick Actions并指定ItemsSource：

要在代碼中將GridControl綁定到數(shù)據(jù)，請指定屬性：

XAML

<Window
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:BindToLocalCollection"
xmlns:dxg="http://schemas.devexpress.com/winfx/2008/xaml/grid"
x:Class="BindToLocalCollection.MainWindow"
mc:Ignorable="d"
Title="MainWindow" Height="450" Width="800">
<Window.DataContext>
<local:ViewModel/>
</Window.DataContext>
<Grid>
<dxg:GridControl AutoGenerateColumns="AddNew"
EnableSmartColumnsGeneration="True"
ItemsSource="{Binding Source}">
<dxg:GridControl.View>
<dxg:TableView/>
</dxg:GridControl.View>
</dxg:GridControl>
</Grid>
</Window>

4. 運行項目，GridControl為綁定數(shù)據(jù)源中的所有字段生成列。
