MVVM light Binding Path not working

MVVM light Binding Path not working - c#

I'm trying to bind a variable to show in a label's content.
I use Galasoft's MVVM light to achieve this.
I send my viewmodel, my window and my window.cs. The issue is that nothing happens when I increase the values but something should.
Window: I have binding on only one label

{

}
private void Back_Click(object sender, RoutedEventArgs e)
{
MainWindow mw = new MainWindow();
mw.Show();
Close();
}
}
}

You forgot to set the DataContext of the Window.
You can do that for example in the constructor of the Settings class:
public Settings(bool isPlaymodeSingle)
{
InitializeComponent();
this.isPlaymodeSingle = isPlaymodeSingle;
svm = new SettingsVM();
DataContext = svm; // here
}

Increment textbox value on button click WPF C#

What I'm trying to do is I have a textbox, and a '-' and a '+' button, and on button click I need to decrease/increase it's value. I have close to 0 experience with WPF, we only learnt console apps in school and now we got this task and I have no idea why this code sample is not working:

Any help is appreciated!

ertek++ is a postfix increment operator. The result of ertek++ is the value of ertek before the operation.
use simple + operator:
private void Button_Click_1(object sender, RoutedEventArgs e)
{
int ertek = Convert.ToInt32(textBox1.Text);
if (ertek < 9)
{
textBox1.Text = $"{ertek+1}";
}
}

C# WPF Application save settings in UserControl

I have a main application at this there are border different buttons. This also includes the "Einstellung" button. Pressing this button should display a different content than before. This I realized with a UserControl.
Now you can make settings in this user control and save them.
This saving I made in the Settings
and with the Code
Vorschau.Properties.Settings.Default.BreiteBitmap = Int32.Parse(tbBreiteBitmap.Text);
Vorschau.Properties.Settings.Default.HoeheBitmap = Int32.Parse(tbHoeheBitmap.Text);
Vorschau.Properties.Settings.Default.AnzahlKoordinaten = Int32.Parse(tbAnzahlKoordinaten.Text);
Now I press the "Speichern" button. He saves me the settings.
I now change the UserControl, so I click on a button "Vorschau" and a new content is displayed to me. If I now click again on "Einstellung" is the content still there, as I have stored it.
But the problem comes. I close the application and I open it again. Now I click on the button "Einstellung" in the textboxes is only everywhere a 0 in it.
This should not be so, but the content should be from there in the past.
I retrieve this content when I start the application. See the code snippet.
public UCEinstellung()
{
InitializeComponent();
//Lade der Einstellungen
tbBreiteBitmap.Text = Vorschau.Properties.Settings.Default.BreiteBitmap.ToString();
tbHoeheBitmap.Text = Vorschau.Properties.Settings.Default.HoeheBitmap.ToString();
tbAnzahlKoordinaten.Text = Vorschau.Properties.Settings.Default.AnzahlKoordinaten.ToString();
}
AND
public MainWindow()
{
InitializeComponent();
MouseDown += Window_MouseDown;
einstellung.tbBreiteBitmap.Text = Vorschau.Properties.Settings.Default.BreiteBitmap.ToString();
einstellung.tbHoeheBitmap.Text = Vorschau.Properties.Settings.Default.HoeheBitmap.ToString();
einstellung.tbAnzahlKoordinaten.Text = Vorschau.Properties.Settings.Default.AnzahlKoordinaten.ToString();
}
Unfortunately this does not work.
I hope you can tell me where the error lies. In another application WITHOUT usercontrol works, this store and retrieve properly.

It looks like you are just assigning the properties and not saving them. You need to call the Save method
Vorschau.Properties.Settings.Default.Save();
You can find the file under %userprofile%\appdata\local after saving. See here for details.
For this to work, the scope of the setting should be "User".

Add user control on a button click from another user control

i have two user control and when i click on a button from the first user control ,another user control shows up :
The first user control is:
using System;
using System.Collections.Generic;
using System.Collections.ObjectModel;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
namespace Navigateur.Presentation.UserControlWork
{
/// <summary>
/// Logique d'interaction pour ListeBlanche.xaml
/// </summary>
public partial class ListeBlanche : UserControl
{
public ListeBlanche()
{
InitializeComponent();
}
private async void Button_Click_1(object sender, RoutedEventArgs e)
{
ServiceReferenceParent.ParentServiceClient wcfParent = new ServiceReferenceParent.ParentServiceClient();
bool existe = await wcfParent.LogInAsync(textmail.Text, textpass.Text);
if (existe)
{
//grid.Children.Remove(this);
//this.Visibility = System.Windows.Visibility.Collapsed;
//ParentControl parmain = new ParentControl();
//parmain.Visibility = System.Windows.Visibility.Visible;
//parmain.
}
else
{
Popup1.IsOpen = true;
}
}
private void Button_Click_2(object sender, RoutedEventArgs e)
{
MainWindow main = new MainWindow();
ParentControl parmain = new ParentControl();
main.gridMain.Children.Add(parmain);
parmain.Visibility = System.Windows.Visibility.Visible;
this.Visibility = System.Windows.Visibility.Hidden;
}
}
}
and when i click on "Button_Click_2",ParentControl shows up but it never shows.

and this is my main window xaml code:

<Grid x:Name="gridMain">
<auth:ListeBlanche ClickedInUserControl="OnClickedInUserControl"></auth:ListeBlanche>
</Grid>
</Window>

I think you need to use a RoutedEvent in your UserControl to get this to work.
So change your click event in your usercontrol to:
public event RoutedEventHandler ClickedInUserControl;
private void Button_Click_2(object sender, RoutedEventArgs e)
{
if (ClickedInUserControl != null)
{
ClickedInUserControl(this, new RoutedEventArgs());
}
}
Then in you MainWindow's xaml add this too the UserControl:
ClickedInUserControl="OnClickedInUserControl"
And then add the event handler on your mainwindow's codebehind
private void OnClickedInUserControl(object sender, RoutedEventArgs e)
{
ParentControl parmain = new ParentControl();
this.gridMain.Children.Add(parmain);
parmain.Visibility = System.Windows.Visibility.Visible;
// also remove the original usercontrol from the grid and collapse it's vilisibilty
}
Also, I would highly recommend that you look into using Commands rather than Events for this kind of thing, but I used events because that's what you were working with.

TextBox input to TextBlock in other page

I'm using c# and WPF web application and I want to build a simple form which contains two text boxes for user input (name and phone number) and a "send" button. when the user clicks on the send button it will redirect to an other page and will display (with textblock) the entered values.
I tried to read about data binding, but still didn't success to make it work.
1. How do I save the entered values into a variable ?
2. How do I call these variables from the second page and display the saved text ?
Hope for help, thanks!
xaml code of the form:
<TextBlock Height="20" Width="120" Margin="36,43,144,237">enter details:</TextBlock>
<TextBlock Height="20" Width="40" Margin="36,69,224,211">Name:</TextBlock>
<TextBlock Height="20" Width="40" Margin="36,103,224,177">Phone:</TextBlock>
<!--textboxes-->
<TextBox Height="20" Width="95" Margin="100,69,104,211" Name="getName" Background="Gray"/>
<TextBox Height="20" Width="95" Margin="100,103,105,177" Name="getPhoneNumber" Background="Gray"/>
<!-- -->
<Button Height="20" Width="50" Margin="218,103,32,177" Name="sendButton" Click="sendButton_Click">send</Button>
what should be the code behind ? i simply want to display the entered values on an other page with textblock.
this is the function i use to redirect to the "result page":
public void sendButton_Click(object sender, RoutedEventArgs e)
{
Submit();
}
void Submit()
{
Page2 resultpage = new Page2();
NavigationService.Navigate(resultpage);
}
Edit:
Ok I succeed to make it work thanks to Mike's answer.
Thanks Mike, for other users this how the code looks like now:
form page xaml code:
<TextBlock Height="20" Width="120" Margin="36,43,144,237">enter details:</TextBlock>
<TextBlock Height="20" Width="40" Margin="36,69,224,211">Name:</TextBlock>
<TextBlock Height="20" Width="40" Margin="36,103,224,177">Phone:</TextBlock>
<!--textboxes-->
<TextBox Height="20" Width="95" Margin="100,69,104,211" Name="getName" Background="Gray"/>
<TextBox Height="20" Width="95" Margin="100,103,105,177" Name="getPhoneNumber" Background="Gray"/>
<!-- -->
<Button Height="20" Width="50" Margin="218,103,32,177" Name="sendButton" Click="sendButton_Click">send</Button>
form page c# behind code:
public partial class Page1 : Page
{
public Page1()
{
InitializeComponent();
}
public void sendButton_Click(object sender, RoutedEventArgs e)
{
Submit();
}
void Submit()
{
Page2 resultpage = new Page2(getName.Text, getPhoneNumber.Text);
NavigationService.Navigate(resultpage);
}
}
result page xaml code:
<Grid>
<TextBlock x:Name="showName" Height="50" Width="100" Margin="65,125,73,125" Text="{Binding ElementName=showName, Path=Text}" />
</Grid>
result page c# code behind:
public Page2(string name, string phoneNumber)
{
InitializeComponent();
showName.Text = name;
}
Thanks again Mike :)

Ok here is what I would do. You can create arguments in the constructor of your Page2:
public Page2(string name, string phoneNumber)
{
//login to handle name and phone number
}
On your first page you can just pass name and phone number using the Name property in the xaml.
void Submit()
{
Page2 resultpage = new Page2(getName.Text, getPhoneNumber.Text);
NavigationService.Navigate(resultpage);
}

WPF bind slider's mouseposition value to textblock

I have a slider with minimum 0 and max 100.
I have a popup window that is visible when I mouseover the slider.
Currently, I binded the popup with the slider value.
What I want is:
When I move the mouse over the slider, I want to see value that suppose to be in that position.
For example:
My XAML:
<Window x:Class="WPFMavka.VideoPlayer"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:WPFMavka"
Title="MainWindow" WindowStyle="None" Width="1920" Height="1080" WindowState="Maximized" KeyboardNavigation.TabNavigation="None" Closing="Window_Closing">
<Grid Name="tst">
<local:MetroSlider x:Name="bla" MouseMove="Rectangle_MouseMove" MouseLeave="Rectangle_MouseLeave" IsMoveToPointEnabled="True" HorizontalAlignment="Left" Width="542" VerticalAlignment="Top" Margin="116,839,0,0" Value="0" Style="{DynamicResource SliderStyle1}" Height="66" AutoToolTipPrecision="0" AutoToolTipPlacement="TopLeft"/>
<Popup Name="floatingTip" AllowsTransparency="True" Placement="Relative" PlacementTarget="{Binding ElementName=bla}">
<Border BorderBrush="Black" BorderThickness="1" Padding="4">
<TextBlock Text="{Binding ElementName=bla, Path=Value}"></TextBlock>
</Border>
</Popup>
</Grid>
</Window>
My Code-Behind:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Controls.Primitives;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Shapes;
namespace WPFMavka
{
/// <summary>
/// Interaction logic for VideoPlayer.xaml
/// </summary>
public partial class VideoPlayer : Window
{
public VideoPlayer()
{
InitializeComponent();
}
private void Window_Closing(object sender, System.ComponentModel.CancelEventArgs e)
{
Environment.Exit(1);
}
private void Rectangle_MouseMove(object sender, MouseEventArgs e)
{
if (!floatingTip.IsOpen) { floatingTip.IsOpen = true; }
Point currentPos = e.GetPosition(bla);
floatingTip.HorizontalOffset = currentPos.X-14;
floatingTip.VerticalOffset = -32;
}
private void Rectangle_MouseLeave(object sender, MouseEventArgs e)
{
floatingTip.IsOpen = false;
}
}
}

Found a better solution - changing the TextBlock onMouseOver the slide > I get the current position of mouse on the slider and then uses .ValueFromPoint()
XAML:
<Window x:Class="WPFMavka.VideoPlayer"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:WPFMavka"
Title="MainWindow" WindowStyle="None" Width="1920" Height="1080" WindowState="Maximized" KeyboardNavigation.TabNavigation="None" Closing="Window_Closing">
<Grid Name="tst">
<local:MetroSlider x:Name="slider" MouseMove="slider_MouseMove" MouseLeave="slider_MouseLeave" IsMoveToPointEnabled="True" HorizontalAlignment="Left" Width="746" VerticalAlignment="Top" Margin="330,851,0,0" Value="0" Style="{DynamicResource SliderStyle1}" Height="44"/>
<Popup Name="floatingTip" AllowsTransparency="True" Placement="Relative" PlacementTarget="{Binding ElementName=slider}">
<Border Name="floatingTipBorder" BorderBrush="Black" BorderThickness="1" Padding="4">
<TextBlock Name="sliderTextBlock"/>
</Border>
</Popup>
</Grid>
</Window>
Code-Behind:
private void slider_MouseMove(object sender, MouseEventArgs e)
{
if (!floatingTip.IsOpen) { floatingTip.IsOpen = true; }
Point currentPos = e.GetPosition(slider);
Track _track = slider.Template.FindName("PART_Track", slider) as Track;
sliderTextBlock.Text = _track.ValueFromPoint(currentPos).ToString();
floatingTip.HorizontalOffset = currentPos.X -(floatingTipBorder.ActualWidth / 2);
floatingTip.VerticalOffset = -32;
}
private void slider_MouseLeave(object sender, MouseEventArgs e)
{
floatingTip.IsOpen = false;
}

You can use AttachedCommands for this. You can download the library from here. So in this case you could do something like:
<Window x:Class="WPFMavka.VideoPlayer"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:WPFMavka"
xmlns:AttachedCommand="clr-namespace:AttachedCommandBehavior;assembly=AttachedCommandBehavior"
Title="MainWindow"
WindowStyle="None"
Width="1920"
Height="1080"
WindowState="Maximized"
KeyboardNavigation.TabNavigation="None"
Closing="Window_Closing">
<Grid Name="tst">
<local:MetroSlider x:Name="bla"
MouseMove="Rectangle_MouseMove"
MouseLeave="Rectangle_MouseLeave"
IsMoveToPointEnabled="True"
HorizontalAlignment="Left"
Width="542" VerticalAlignment="Top"
Margin="116,839,0,0"
Value="0"
Style="{DynamicResource SliderStyle1}"
Height="66" AutoToolTipPrecision="0"
AutoToolTipPlacement="TopLeft"
AttachedCommand:CommandBehavior.Event="MouseMove"
AttachedCommand:CommandBehavior.Command="{Binding UpdateCurrentMouseTimeCommand}"
AttachedCommand:CommandBehavior.CommandParameter="{Binding ElementName=Bla, Path=Value}"/>
<Popup Name="floatingTip" AllowsTransparency="True"
Placement="Relative"
PlacementTarget="{Binding ElementName=bla}">
<Border BorderBrush="Black" BorderThickness="1" Padding="4">
<TextBlock Text="{Binding CurrentMouseTime, NotifyOnSourceUpdated=True, Mode=OneWay}" />
</Border>
</Popup>
</Grid>
</Window>
Then in your command UpdateCurrentMouseTimeCommand you set the property
private string currentMouseTime = String.Empty;
public string CurrentMouseTime
{
get { return value; }
set
{
if (currentMouseTime == value)
return;
currentMouseTime = value;
OnPropertyChanged("CurrentMouseTime");
}
}
Where the containing class must implement INotifyPropertyChanged.
I hope this helps.

MVVM light Binding Path not working - c#

You forgot to set the DataContext of the Window. You can do that for example in the constructor of the Settings class: public Settings(bool isPlaymodeSingle) { InitializeComponent(); this.isPlaymodeSingle = isPlaymodeSingle; svm = new SettingsVM(); DataContext = svm; // here }
