caliburn.micro

问题 I have a WPF Caliburn.Micro application. I used to have there a DataGrid, and here is a part of the code: <DataGrid x:Name="FirstEntries" Grid.Row="5" AutoGenerateColumns="False" BaseControls:DataGridExtension.Columns="{Binding FirstEntryGridColumns}" CanUserAddRows="False" IsReadOnly="True" SelectedItem="{Binding Path=SelectedFirstEntry}"> <DataGrid.Resources> <conv:StatusToBackgroundColorConverter x:Key="StatusToBackgroundColor"/> </DataGrid.Resources> <DataGrid.ItemContainerStyle> <Style

问题 EDIT: It seems that I finally made it to work. I asked an author of that post which I referred before and he said that it's a known issue. He also gave mi a workaround (in the comment below the post), so I consider this question as closed. But thanks to all of you for time spent with my problems :) I'm trying to learn MVVM with Caliburn Micro framework, but I got problems from the beginning. I'm following this tutorial and I got such a code in App.xaml: <Application x:Class="Caliburn.App"

问题 Problem I have a MVVM application that uses Caliburn.Micro as the MVVM framework and MEF for "dependency injection" (in quotes as I am aware it is not strictly an DI container). The composition process of this large application is starting to take increasingly large amounts of time based on the number of compositions MEF is undertaking during the launch of the application and as such I want to use an animated splash screen. Below I will outline my current code that shows the splash screen on

问题 I use caliburn micro and MEF in wpf and I have this problem. I create shell-view-model: public interface IShellViewModel { void ShowLogOnView(); void ShowMessengerView(PokecAccount account); } [Export(typeof(IShellViewModel))] public class ShellViewModel : Conductor<IScreen>, IShellViewModel { public ShellViewModel() { ShowLogOnView(); } public void ShowLogOnView() { ActivateItem(IoC.Get<LogOnViewModel>()); } public void ShowMessengerView(PokecAccount account) { //send to constructor of

问题 In this thread : Can anybody provide any simple working example of the Conductor<T>.Collection.AllActive usage? I've had part of an answer but I'm still a but confused. I would simply like to reference all my view models into my ShellViewModel to be able to open/close ContentControls, but without injecting all of them in the constructor. In the answer, it is suggested to inject an interface in the constructor of the ShellViewModel. If I do that, do I have to inject all my ViewModels in a

问题 I wrote a simple program with MVVM (C#) and XAML using Caliburn.Micro library, But some actions didn't work: update an item content get selected item get specific item move up and move down records enable or disable buttons when Add button clicked Any help would be appreciated. My GUI code: // Views\MainView.xaml <Window x:Class="ListBox_CaliburnMicro.MainView" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:cal=

问题 I am trying to implement so guard handling with Caliburn.Micro but I am getting an invalid cast exception when the application runs. The Property: public Account UserAccount { get { return account; } set { account = value; NotifyOfPropertyChange(() => UserAccount); NotifyOfPropertyChange(() => CanSaveAndNavigateToComposeView()); } } The Method: public void SaveAndNavigateToComposeView() { CommitAccountToStorage(); navigationService.UriFor<ComposeViewModel>().Navigate(); } The Guard: public

问题 I have the problem, that my CanSave method doesn't get called, when I change a binded property. View The View contains of some Labels and TextBoxes ... nothing special... The TextBoxes are binded to the properties of an object. <Label Target="{Binding ElementName=txtTitle}" Grid.Column="0" Grid.Row="0" Content="Titel" Foreground="White" /> <TextBox Name="txtTitle" Grid.Column="1" Grid.Row="0" Text="{Binding NewBook.Title}" /> <Label Target="{Binding ElementName=txtAuthor}" Grid.Column="0"

问题 I have a Windows WPF app in which I'm using Caliburn.Micro. The main window view/viewmodel is handled by Caliburn.Micro. One of it's buttons pops up a new dialog window which uses a different view-viewmodel. In this dialog I have a container (list box and some filter controls) that I want to make into a reusable control so that I can include it in other dialogs. To do this I extracted from the dialog's view and viewmodel the relevant code and created a new view and viewmodel. This all looks
