Jeg bruker caliburn micro. Jeg er ny i programmering og selvlært. Hvordan kan jeg få tilgang til proberti i viewmodel fra view.xaml.cs eller sende informasjon mellom dem? Jeg prøvde å implementere ved hjelp av event aggregator, programmet vil ikke starte. Her er koden jeg bruker: ShellView.xaml.cs public partial class ShellView : Window { public ShellView() { InitializeComponent(); DataContext = this; } private List<FlagDisplayModel> _flags = new List<FlagDisplayModel>(); public List<FlagDisplayModel> flags { get { return _flags; } set { _flags = value;} } private List<SignalDisplayModel> _signals = new List<SignalDisplayModel>(); public List<SignalDisplayModel> signals { get { return _signals; } set { _signals = value; } } public void InitializeColume() { var gridView = new GridView(); gridView.AllowsColumnReorder = false; TextBlock textBlockr = new TextBlock(); textBlockr.Text = "Oppcode"; textBlockr.RenderTransformOrigin = new Point(0.5, 0.5); textBlockr.LayoutTransform = new RotateTransform() { Angle = 90 }; textBlockr.HorizontalAlignment = HorizontalAlignment.Center; GridViewColumn Oppcode = new GridViewColumn { Header = textBlockr, DisplayMemberBinding = new Binding("Oppcode") }; gridView.Columns.Add(Oppcode); TextBlock textBlocke = new TextBlock(); textBlocke.Text = "CodeNavn"; textBlocke.RenderTransformOrigin = new Point(0.5, 0.5); textBlocke.LayoutTransform = new RotateTransform() { Angle = 90 }; textBlocke.HorizontalAlignment = HorizontalAlignment.Center; GridViewColumn CodeNavn = new GridViewColumn { Header = textBlocke, DisplayMemberBinding = new Binding("CodeNavn") }; gridView.Columns.Add(CodeNavn); foreach (FlagDisplayModel p in flags) { FrameworkElementFactory checkBox = new FrameworkElementFactory(typeof(CheckBox)); checkBox.Name = $"{p.FlagNavn}"; checkBox.SetBinding(CheckBox.IsCheckedProperty, new Binding("Name[" + $"{p.FlagNavn}" + "]")); // binding her DataTemplate dataTemplate = new DataTemplate() { VisualTree = checkBox }; TextBlock textBlock = new TextBlock(); textBlock.Text = $"{p.FlagNavn}"; textBlock.RenderTransformOrigin = new Point(0.5, 0.5); textBlock.LayoutTransform = new RotateTransform() { Angle = 90 }; textBlock.HorizontalAlignment = HorizontalAlignment.Center; GridViewColumn check = new GridViewColumn { Header = textBlock, CellTemplate = new DataTemplate { VisualTree = checkBox } }; gridView.Columns.Add(check); } GridViewColumn emti = new GridViewColumn { Header = " ", Width = 20, DisplayMemberBinding = new Binding("emti") }; gridView.Columns.Add(emti); foreach (SignalDisplayModel p in signals) { FrameworkElementFactory checkBox = new FrameworkElementFactory(typeof(CheckBox)); checkBox.Name = $"{p.SignalNavn}"; checkBox.SetBinding(CheckBox.IsCheckedProperty, new Binding("Name[" + $"{p.SignalNavn}" + "]")); // binding her DataTemplate dataTemplate = new DataTemplate() { VisualTree = checkBox }; TextBlock textBlock = new TextBlock(); textBlock.Text = $"{p.SignalNavn}"; textBlock.RenderTransformOrigin = new Point(0.5, 0.5); textBlock.LayoutTransform = new RotateTransform() { Angle = 90 }; textBlock.HorizontalAlignment = HorizontalAlignment.Center; GridViewColumn check = new GridViewColumn { Header = textBlock, CellTemplate = new DataTemplate { VisualTree = checkBox } }; gridView.Columns.Add(check); } MyListView.View = gridView; } private void SetItemsSource() { Dictionary<string, bool> test5 = new Dictionary<string, bool>(); foreach (FlagDisplayModel item in flags) { test5.Add(item.FlagNavn, false); } foreach (SignalDisplayModel signal in signals) { test5.Add(signal.SignalNavn, false); } Items = new ObservableCollection<MyDataClass>{ }; Items.Add(new MyDataClass { Oppcode = "0", CodeNavn = "pall", Name = test5 }); Items.Add(new MyDataClass { Oppcode = "1", CodeNavn = "pal", Name = test5 }); Items.Add(new MyDataClass { Oppcode = "2", CodeNavn = "paffffffffffffl", Name = test5 }); } private void CreateViewButtonClicked(object sender, RoutedEventArgs e) { //flags.Add(new FlagDisplayModel { id = 1, FlagNavn = "tedg", nr = 0 }); //flags.Add(new FlagDisplayModel { id = 2, FlagNavn = "test", nr = 0 });
