WPF Datagrid: No data being displays
Can someone please tell me why no data is being displaysed in my WPF DataGrid with the following code:
<Window x:Class="WpfApplication1.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Window1" Height="300" Width="300"
xmlns:my="ht开发者_如何学JAVAtp://schemas.microsoft.com/wpf/2008/toolkit"
>
<Grid>
<my:DataGrid Name="myDataGrid" ItemsSource="{Binding Customers}">
<my:DataGrid.Columns>
<my:DataGridTextColumn Header="Name" Binding="{Binding Name}" />
<my:DataGridTextColumn Header="Name1" Binding="{Binding Name1}" />
</my:DataGrid.Columns>
</my:DataGrid>
</Grid>
</Window>
public partial class Window1 : Window
{
public Window1()
{
InitializeComponent();
IList<Customers> list = new List<Customers>();
list.Add(new Customers() { Name = "Name1", Name2 = "Name2" });
list.Add(new Customers() { Name = "Name1", Name2 = "Name2" });
list.Add(new Customers() { Name = "Name1", Name2 = "Name2" });
myDataGrid.DataContext = new Customers() { Name = "Name1", Name2 = "Name2" };
}
}
public class Customers
{
public string Name { get; set; }
public string Name2 { get; set; }
}
Well. There are a number of issues here.
- You are setting
DataContext
to benew Customers()
object instead of a collection of customers (namely thelist
) - There should be
ItemsSource="{Binding}"
in order to bind ItemsSource directly to the DataContext which is going to be the collection. - As far as I remember
DataGrid
has it'sAutoGenerateColumns
beingtrue
by default, so it will have 4 columns, 2 created by yourself and 2 autogenerated.
In addition to everything alpha-mouse said, which was all on the money...
consider making your data context a class member of type ObservableCollection:
public partial class Window1 : Window
{
private ObservableCollection<Customers> customers;
public Window1()
{
InitializeComponent();
this.customers = new ObservableCollection<Customers>();
Using an ObservableCollection instead of List ensures that changes to the collection content will automatically be picked up by the grid without you having to do any kind of NotifyPropertyChanged.
