Missing References in References Manages "No items found" - WPF [duplicate] - c#

Is there a standard message box in WPF, like WinForms' System.Windows.Forms.MessageBox.Show(), or should I use the WinForms message box?

The WPF equivalent would be the System.Windows.MessageBox. It has a quite similar interface, but uses other enumerations for parameters and return value.

You can use this:
MessageBoxResult result = MessageBox.Show("Do you want to close this window?",
"Confirmation",
MessageBoxButton.YesNo,
MessageBoxImage.Question);
if (result == MessageBoxResult.Yes)
{
Application.Current.Shutdown();
}
For more information, visit MessageBox in WPF.

WPF contains the following MessageBox:
if (MessageBox.Show("Do you want to Save?", "Confirm",
MessageBoxButton.YesNo, MessageBoxImage.Question) == MessageBoxResult.Yes)
{
}

The equivalent to WinForms' MessageBox in WPF is called System.Windows.MessageBox.

In WPF it seems this code,
System.Windows.Forms.MessageBox.Show("Test");
is replaced with:
System.Windows.MessageBox.Show("Test");

The MessageBox in the Extended WPF Toolkit is very nice. It's at Microsoft.Windows.Controls.MessageBox after referencing the toolkit DLL. Of course this was released Aug 9 2011 so it would not have been an option for you originally. It can be found at Github for everyone out there looking around.

If you want to have your own nice looking wpf MessageBox:

{
public MessageboxNew()
{
InitializeComponent();
//second time show error solved
if (Application.Current == null) new Application();
Application.Current.ShutdownMode = ShutdownMode.OnExplicitShutdown;
}
private void ButtonBase_OnClick(object sender, RoutedEventArgs e)
{
DialogResult = true;
}
private void cancel_Click(object sender, RoutedEventArgs e)
{
DialogResult = false;
}
private void FrameworkElement_OnLoaded(object sender, RoutedEventArgs e)
{
this.MouseDown += delegate { DragMove(); };
}
}
then create a class to use this :
public class Mk_MessageBox
{
public static bool? Show(string title, string text)
{
MessageboxNew msg = new MessageboxNew
{
TitleBar = {Text = title},
Textbar = {Text = text}
};
msg.noBtn.Focus();
return msg.ShowDialog();
}
}
now you can create your message box like this:
var result = Mk_MessageBox.Show("Remove Alert", "This is gonna remove directory from host! Are you sure?");
if (result == true)
{
// whatever
}
copy this to App.xaml inside

for logic how can i make my own messagebox

As the others say, there is a MessageBox in the WPF namespace (System.Windows).
The problem is that it is the same old messagebox with OK, Cancel, etc. Windows Vista and Windows 7 have moved on to use Task Dialogs instead.
Unfortunately there is no easy standard interface for task dialogs. I use an implementation from CodeProject KB.

Maybe the code here below helps:
using Windows.UI.Popups;
namespace something.MyViewModels
{
public class TestViewModel
{
public void aRandonMethode()
{
MyMessageBox("aRandomMessage");
}
public async void MyMessageBox(string mytext)
{
var dialog = new MessageDialog(mytext);
await dialog.ShowAsync();
}
}
}

How to display current date and time on Wpf statusbar

I want to know how to display current date and time on a WPF statusbar.
I know this is too basic a question, but I am new to .net WPF,
and I know this can be done in a Form application easily.
Thanks in advance.
Ting
Create a wpf project. In your MainWindow.xaml add the StatusBar and handle Loaded event of window.
<Window
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
x:Class="WpfApp1.MainWindow"
Title="MainWindow" Height="450" Width="800" Loaded="Window_Loaded">
<Grid>
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<StatusBar Grid.Row="1">
<TextBlock x:FieldModifier="private" x:Name="myDateTime"/>
</StatusBar>
</Grid>
</Window>
In the MainWindow.xaml.cs add the following namespaces (if they are not exist):
using System;
using System.Windows;
using System.Windows.Threading;
And in the Loaded enevt handler you can use DispatcherTimer for update textblock text property every second:
private void Window_Loaded(object sender, RoutedEventArgs e)
{
DispatcherTimer timer = new DispatcherTimer(TimeSpan.FromSeconds(1), DispatcherPriority.Normal, (object s, EventArgs ev) =>
{
this.myDateTime.Text = DateTime.Now.ToString("yyyy/MM/dd hh:mm:ss");
}, this.Dispatcher);
timer.Start();
}
Also there are a lot of examples for customize wpf controls using Template and Style properties. just search for it.
Styles and templates in WPF
The WPF StatusBar control
and many more.
Also you can implement your custom WPFTimer. This simple implementation get you an idea for do this.
public class WPFTimer : TextBlock
{
#region static
public static readonly DependencyProperty IntervalProperty = DependencyProperty.Register("Interval", typeof(TimeSpan), typeof(WPFTimer), new PropertyMetadata(TimeSpan.FromSeconds(1), IntervalChangedCallback));
public static readonly DependencyProperty IsRunningProperty = DependencyProperty.Register("IsRunning", typeof(bool), typeof(WPFTimer), new PropertyMetadata(false, IsRunningChangedCallback));
private static void IntervalChangedCallback(DependencyObject d, DependencyPropertyChangedEventArgs e)
{
WPFTimer wpfTimer = (WPFTimer)d;
wpfTimer.timer.Interval = (TimeSpan)e.NewValue;
}
private static void IsRunningChangedCallback(DependencyObject d, DependencyPropertyChangedEventArgs e)
{
WPFTimer wpfTimer = (WPFTimer)d;
wpfTimer.timer.IsEnabled = (bool)e.NewValue;
}
#endregion
private readonly DispatcherTimer timer;
[Category("Common")]
public TimeSpan Interval
{
get
{
return (TimeSpan)this.GetValue(IntervalProperty);
}
set
{
this.SetValue(IntervalProperty, value);
}
}
[Category("Common")]
public bool IsRunning
{
get
{
return (bool)this.GetValue(IsRunningProperty);
}
set
{
this.SetValue(IsRunningProperty, value);
}
}
public WPFTimer()
{
this.timer = new DispatcherTimer(this.Interval, DispatcherPriority.Normal,this.Timer_Tick ,this.Dispatcher);
this.timer.IsEnabled = false;
}
private void Timer_Tick(object sender, EventArgs e)
{
this.SetValue(TextProperty, DateTime.Now.ToString("yyyy/MM/dd hh:mm:ss"));
}
}
And now you have a control that can use it in the designer.
<Window
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:WpfApp1"

Title="MainWindow" Height="450" Width="800">
<Grid>
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<StatusBar Grid.Row="1">
<local:WPFTimer IsRunning="True"/>
</StatusBar>
</Grid>
</Window>
You can do it this way, using wpf animation and binding, and no background code :)

Closing Material Design DialogHost from Code

I'm trying to find a way to initiate the close of an active DialogHost from code, but have been unable to find the right syntax. I think the main challenge is accessing the DialogHost from a class outside of the MainWindow code behind.
The entirety of my XAML:
<Window x:Class="MaterialDesignTest.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:MaterialDesignTest"
mc:Ignorable="d"

TextElement.Foreground="{DynamicResource MaterialDesignBody}"
TextElement.FontWeight="Regular"
TextElement.FontSize="13"
TextOptions.TextFormattingMode="Ideal"
TextOptions.TextRenderingMode="Auto"
Background="{DynamicResource MaterialDesignPaper}"
FontFamily="{DynamicResource MaterialDesignFont}">
<materialDesign:DialogHost Identifier="RootDialog" Loaded="DialogHost_Loaded">
<Grid>
<StackPanel>
<Button Width="100" x:Name="SearchRestore" Margin="0 150 0 0" Command="{x:Static materialDesign:DialogHost.OpenDialogCommand}" materialDesign:DialogHost.DialogClosingAttached="SearchRestore_OnDialogClosing"
Content="Restore" Click="SearchRestore_Click">
<Button.CommandParameter>
<StackPanel Margin="10">
<TextBlock Text="Restoring..."/>
<Button Name="CircleButton" Margin="0 50 0 0" Style="{StaticResource MaterialDesignFloatingActionButton}"
Command="{Binding SaveComand}" IsHitTestVisible="False"
materialDesign:ButtonProgressAssist.IsIndicatorVisible="{Binding IsSaving}"
materialDesign:ButtonProgressAssist.Value="{Binding SaveProgressButton}">
<materialDesign:PackIcon Height="24" Width="24" Foreground="White">
<materialDesign:PackIcon.Style>
<Style TargetType="materialDesign:PackIcon" BasedOn="{StaticResource {x:Type materialDesign:PackIcon}}">
<Setter Property="Kind" Value="CloudSync" />
<Style.Triggers>
<DataTrigger Binding="{Binding IsSaveComplete}" Value="True">
<Setter Property="Kind" Value="Check" />
<DataTrigger.EnterActions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Storyboard.TargetProperty="Opacity" From="0" To="1" Duration="0:0:0.8" />
</Storyboard>
</BeginStoryboard>
</DataTrigger.EnterActions>
</DataTrigger>
</Style.Triggers>
</Style>
</materialDesign:PackIcon.Style>
</materialDesign:PackIcon>
</Button>
</StackPanel>
</Button.CommandParameter>
</Button>
</StackPanel>
</Grid>
</materialDesign:DialogHost>
And the code from which I need to initiate the close (this is in a view model, not the MainWindow code behind):
private async void progressTimerTick(object sender, EventArgs e)
{
if (progress < 100 && cycles < 2)
{
if (progress == 99)
{
cycles++;
progress = 0;
}
IsSaveComplete = false;
IsSaving = true;
progress++;
SaveProgressButton = progress;
}
else
{
IsSaveComplete = true;
IsSaving = false;
progressTimer.Enabled = false;
SaveProgressButton = 0;
await PutTaskDelay();
//Close dialog here
}
}
There are 3 ways to close a dialog in MDIX:
var dialogResult = await DialogHost.Show(myDialogControl, (sender, args) =>
{
args.Session.Close(false);
});
or
DialogHost.CloseDialogCommand.Execute(null,null);
or
DialogHostInstance.IsOpen = false;
Regarding #Talha answer.
I have tried your solution, however, it didn't work. On the other hand, I found a way to fix it:
var drawer = DrawerHost.CloseDrawerCommand;
drawer.Execute(null, null);
It looks the same, but worked for me.

WPF / C# - Dialog Window doesn't respond to Touch

I'm developing a C# WPF application that is intended to run on full Windows 10 tablets using exclusively touch. So far, the app works great, except for one of my dialog windows has buttons that don't like to be touched.
Dialog Window XAML:
<Window x:Class="Commencement_Organizer.ConfirmStudentWindow"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

<Window.Triggers>
<EventTrigger RoutedEvent="Window.Loaded">
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Duration="00:00:0.2" Storyboard.TargetProperty="Opacity" From="0" To="1" />
</Storyboard>
</BeginStoryboard>
</EventTrigger>
</Window.Triggers>
<Grid Background="#FF171717">
<Grid Margin="1" Background="White">
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="*" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Button x:Name="YesButton" Content="Yes" Margin="25" Grid.Row="2" Click="YesButton_Click"/>
<Button x:Name="NoButton" Content="No" Margin="25" Grid.Row="2" Grid.Column="1" Click="NoButton_Click"/>
<Label x:Name="label" Content="Confirm your name" Margin="0" Grid.ColumnSpan="2" HorizontalAlignment="Center" VerticalAlignment="Center" FontSize="24"/>
<Label x:Name="nameLabel" Content="Label" HorizontalAlignment="Center" Margin="0" Grid.Row="1" VerticalAlignment="Center" Grid.ColumnSpan="2" FontSize="24" FontWeight="Bold"/>
</Grid>
</Grid>
Implementation (C#):
ConfirmStudentWindow confirmWindow = new ConfirmStudentWindow(student);
confirmWindow.Confirm += OnConfirm;
// This window makes everything behind the dialog window a grey tint, which makes the dialog more prominent
var darkwindow = new Window()
{
Background = Brushes.Black,
Opacity = 0.4,
AllowsTransparency = true,
WindowStyle = WindowStyle.None,
WindowState = WindowState.Maximized,
Topmost = true,
Effect = new BlurEffect()
};
darkwindow.Show(); // Show grey background tint
confirmWindow.ShowDialog(); // Stops main UI thread
darkwindow.Close();
Everything about this works as intended, except when I try to use a touchscreen to use those buttons, they just stay highlighted, but don't actually click. Works perfect with a mouse.
Tested on 2 different Windows 10 Devices (Surface Pro 2 and Surface Book).
To put it in the form of a question:
Why does launching this window as a Dialog make it resistant to touch, but not if it's launched as a regular window?
Edit - New Question:
Is there any way to simulate a Dialog window other than launching a regular window that always stays on top and then put a tinted overlay behind it while giving the window an eventhandler that provides the result of the user input?
I tried your example and it is running without any problem at my end. I am using DELL notebook with touch display with W10 and .NET 4.5.2. One thing that I can suggest you is to try to hook up StylusUp (or StylusDown that depends on your logic) event on buttons in dialog. I did encounter similar problems in the past when only click event was managed.
This worked for me, confirm method was called and dialog closed.

Comparing two identical .Show() methods, one being executed from a ViewModel and the other executed in code-behind, I found that the code-behind instance did not detect touches.
My solution was to invoke the method on the main UI thread from code-behind:
Application.Current.Dispatcher.BeginInvoke(DispatcherPriority.Normal, (Action)(() =>
{
window.Show()
}));
Beware that if you expect a result from the dialog then you will need to include it within the `Dispatched.BeginInvoke' method, otherwise it will not work correctly.
Ideally, grouping all relevant logics within would be the best approach.

Mahapps, themes not applying to user controls

I have a single MetroWindow which loads with default Color. I have an option for user to change the style. In the window I use a Content control to set the user control dynamically from code behind when initializing this window (This window is initialized from another application so there is no app.xaml and I use the resources in the window itself). The code of the main windows is below. In the User Control I am using some labels and a tab control. On the window I have an option for user to be able to change the theme choosing from available themes (as in your demo project). In all labels I use dynamics resources.
When the window loads for first time the default color is applied and all inner controls have the same theme as well. When I change the theme from window top, the window border, title, glow changes but the inner control stays the old theme (like the tab control headers etc.) I have tried everything but that does not seem to change.
Below is my code:

My User control Code behind:
public partial class UCDemo : UserControl
{
private VMDemo CatalogVM { set; get; }
public UCDemo()
{
try
{
InitializeComponent();
this.DataContext = new VMDemo();
}
catch (Exception de)
{
throw de;
}
}
}
And Finally here is how I call the window and embedded user control from hosted application code:
private void ShowDemoUI()
{
try
{
var child = new UILibrary.UCDemo();
UILibrary.MainWindow window = new UILibrary.MainWindow("Book catalog", child);
window.Height = 450;
window.Width = 700;
window.ShowDialog();
}
catch (Exception de)
{
throw de;
}
}
I think you have 2 options to solve this.
Create your Test.UCDemo as DataTemplate for the VMDemo type and pass the VMDemo for this template to the Content, so your ContentControl will automatically do the magic for you (it's just only a suggestion, i don't tested it)
Put the resources in your Test.UCDemo too.
You need to move all your ResourceDictionaries in the App.xaml
After that I think you need to look at the Theme Manager.
Here is what I've done. In this example all my Content Control have the save Theme even if I change the Theme with a button click:
public ShellView()
{
this.InitializeComponent();
var theme = ThemeManager.DetectAppStyle(Application.Current);
ThemeManager.ChangeAppStyle(Application.Current, ThemeManager.GetAccent("Blue"), theme.Item1);
}
private void Button_Click(object sender, RoutedEventArgs e)
{
var theme = ThemeManager.DetectAppStyle(Application.Current);
ThemeManager.ChangeAppStyle(Application.Current, ThemeManager.GetAccent("Cyan"), theme.Item1);
}
The code need to be in the code behing of your Window (In my case it's ShellView.cs) for you I will assume that it's MainWindow.cs
Here is an other example with a Custom Theme.
public ShellView()
{
this.InitializeComponent();
ThemeManager.AddAccent("YourAccent", new Uri("pack://application:,,,/YourAccent.xaml"));
// Set your Custom Theme when the Window start
var theme = ThemeManager.DetectAppStyle(Application.Current);
ThemeManager.ChangeAppStyle(Application.Current, ThemeManager.GetAccent("YourAccent"), theme.Item1);
}
private void Button_Click(object sender, RoutedEventArgs e)
{
// Change the Theme to Cyan on a simple button click
var theme = ThemeManager.DetectAppStyle(Application.Current);
ThemeManager.ChangeAppStyle(Application.Current, ThemeManager.GetAccent("Cyan"), theme.Item1);
}

How do I change the Textblock value on my splash screen?

I'm trying to make an animated splash screen for my app. I have my MainPage where I show a Popup which has an animation and a textblock. I'd like to change the text of my textblock to show the status of the loading, but I can't change it. Any ideas?
Mainpage code
namespace animatedsplash
{
public partial class MainPage : PhoneApplicationPage
{
BackgroundWorker preloader;
Popup splashPop;
public MainPage()
{
InitializeComponent();
splashPop = new Popup(){IsOpen = true, Child = new Splash() };
preloader = new BackgroundWorker();
RunPreloader();
}
private void RunPreloader()
{
preloader.DoWork += ((s, args) => {
Thread.Sleep(10000);
});
preloader.RunWorkerCompleted += ((s,args) =>
{
this.Dispatcher.BeginInvoke(()=> { this.splashPop.IsOpen = false; });
});
preloader.RunWorkerAsync();
}
}
}

How about something like this:
In Splash.xaml.cs you would have the following:
public string Progress
{
get { return preloader_percentage.Text; }
set { preloader_percentage.Text = value; }
}
And in MainWindow.xaml.cs you change your code to look something like this:
preloader.WorkerReportsProgress = true;
preloader.ProgressChanged += (sender, e) =>
{
this.Dispatcher.BeginInvoke(() =>
(this.splashPop.Child as Splash).Progress = e.ProgressPercentage.ToString());
};
Then in your worker method you need to call preloader.ReportProgress() method several times. As far as I know, that should do it.
Note: There are a lot of design landmines here. I'd suggest getting this code to work, and you can refactor later to make it cleaner and easier to maintain.
