Ok the simplest way to handle DataGridis by binding to an ItemSource.
好的，最简单的处理方法DataGrid是绑定到ItemSource.
The example below shows how to bind your list and how changes upadte the DataGrid.
下面的示例显示了如何绑定列表以及更改如何更新 DataGrid。
public partial class MainWindow : Window
{
private ObservableCollection<ConnectionItem> _connectionitems = new ObservableCollection<ConnectionItem>();
public MainWindow()
{
InitializeComponent();
ConnectionItems.Add(new ConnectionItem { Name = "Item1", Ping = "150ms" });
ConnectionItems.Add(new ConnectionItem { Name = "Item2", Ping = "122ms" });
}
public ObservableCollection<ConnectionItem> ConnectionItems
{
get { return _connectionitems; }
set { _connectionitems = value; }
}
private void button1_Click(object sender, RoutedEventArgs e)
{
// to change a value jus find the item you want in the list and change it
// because your ConnectionItem class implements INotifyPropertyChanged
// ite will automaticly update the dataGrid
// Example
ConnectionItems[0].Ping = "new ping :)";
}
}
public class ConnectionItem : INotifyPropertyChanged
{
private string _name;
private string _ping;
public string Name
{
get { return _name; }
set { _name = value; NotifyPropertyChanged("Name"); }
}
public string Ping
{
get { return _ping; }
set { _ping = value; NotifyPropertyChanged("Ping"); }
}
public event PropertyChangedEventHandler PropertyChanged;
/// <summary>
/// Notifies the property changed.
/// </summary>
/// <param name="property">The info.</param>
public void NotifyPropertyChanged(string property)
{
if (PropertyChanged != null)
{
PropertyChanged(this, new PropertyChangedEventArgs(property));
}
}
}
Xaml:
Xml：
<Window x:Class="WpfApplication4.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:WpfApplication4"
xmlns:properties="clr-namespace:WpfApplication4.Properties"
Title="MainWindow" Height="300" Width="400" Name="UI" >
<Grid>
<DataGrid Name="dataGridView" ItemsSource="{Binding ElementName=UI,Path=ConnectionItems}" Margin="0,0,0,40" />
<Button Content="Change" Height="23" HorizontalAlignment="Left" Margin="5,0,0,12" Name="button1" VerticalAlignment="Bottom" Width="75" Click="button1_Click" />
</Grid>
</Window>
i added a button to show how the data updates when you change something in your list, The class ConnectionItem is where you will store all your info for the datagrid.
我添加了一个按钮来显示当您更改列表中的某些内容时数据如何更新，ConnectionItem 类是您将存储数据网格的所有信息的地方。
Hope this helps
