Achso, ok... Das macht die ganze Sache natürlich etwas komplizierter...
Ich denke, am einfachsten ist es, wenn du das DataGrid an ein ItemSource bindest.
Hier ein Script-Beispiel , wie es jemand auf Stackoverflow gelöst hat:
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));
}
}
}
Ich denke dieses Script sollte dein Problem lösen.
Hier evtl. als XAML:
<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>
