我似乎无法弄清楚如何将数据从wfp导入列表并绑定到datagrid。
xaml表单显示正常
我创建了属性，我创建了一个继承基类的类，即code360。我在线尝试了很多资源，但没有为我工作。我试图硬编码输入，看看它是否会填充网格，但没办法。像这样
{firstName = "Tim", lastName = "Joy",
email = "[email protected]",
phoneNumber = "0988390243",
amount = 200000 }
这是mainWindow.xaml.cs
using System;
using System.Collections.Generic;
using System.Windows;
namespace Code360
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
public class code360
{
public string firstName { get; set; }
public string lastName { get; set; }
public string email { get; set; }
public string phoneNumber { get; set; }
public decimal amount { get; set; }
}
public class Code360Manager : List<code360>
{
public Code360Manager()
{
Add(new code360() {firstName = "Tim", lastName = "Joy", email = "[email protected]", phoneNumber = "0988390243", amount = 200000 });
}
}
private void SubmitButton_Click(object sender, RoutedEventArgs e)
{
//studentGrid.ItemsSource = Code360Manager();
MessageBox.Show("This is to test the firstname", firstName.Text);
}
}
}
这是mainWindow.xaml

1.要使用Binding你需要设置DataContext属性
InitializeComponent();
this.DataContext = this;
2.u需要一个集合来绑定xaml.cs中的DataGrid List<code360> MyList { get; set; } //确保你有这个列表中的数据
3.ItemsSource道具将采取集合所以你需要做它与收集绑定ItemsSource="{Binding MyList } // note the list name is same as the in 2 ponit
这也不是跟随mvvm
我在Visual Studio中粘贴了该代码，除此之外，我遇到了这行ItemsSource="{StaticResource Code360Manager}"的问题
从你分享的XAML中我看不到你在哪里定义资源所以请考虑以下内容。
<Grid.Resources>
<local:Code360Manager x:Key="Code360Manager" />
</Grid.Resources>
在定义网格之后，您将看到数据网格渲染
我相信你需要设置DataContext。在InitializeComponent（）;之后：DataContext = this;编辑:(抱歉。我发了很多评论）。您需要将xaml设置为上下文。通常使用MainWindowViewModel。我更改您的代码以将ItemsSource设置为List <>而不是类：
public partial class MainWindow : Window
{
public List<code360> Code360Manager { get; set; } = new List<code360>();
public MainWindow()
{
InitializeComponent();
Code360Manager.Add(new code360() {firstName = "Tim", lastName = "Joy", email = "[email protected]", phoneNumber = "0988390243", amount = 200000 });
DataContext = this;
}
private void SubmitButton_Click(object sender, RoutedEventArgs e)
{
//studentGrid.ItemsSource = Code360Manager();
MessageBox.Show("This is to test the firstname", firstName.Text);
}
}
public class code360
{
public string firstName { get; set; }
public string lastName { get; set; }
public string email { get; set; }
public string phoneNumber { get; set; }
public decimal amount { get; set; }
}
Grid不会将数据输入作为ItemSource，您需要使用DataContext。就像是：
studentGrid.DataContext = Code360Manager();
如果仍然无效，请尝试使用ListCollectionView，如下所示：
ListCollectionView alist = new ListCollectionView(Code360Manager());
studentGrid.DataContext = alist;
