WPF restoring position in the Combobox

WPF restoring position in the Combobox - c#

There is an Observablecollection Fathers that stores the ID-Firstname-Lastname father. How to make it so that when loading data from the child.lbs file, the ID value that is written in the file under word[4] is selected in the Combobox field? Item values are spelled out using XAML <Combobox "ItemsSource = {Binding Fathers}"/>
That is, so that when the file is loaded, the same values are restored as they were before the shutdown (the so-called Save/Load)

There is a Project: https://github.com/RodKingroo/FatherChild
Who will help, thanks :)

Thanks, #BionicCode 4 ur help
Answer ContextWiew.cs:
using (StreamReader srChild = new StreamReader($"{AppDomain.CurrentDomain.BaseDirectory}/save/child.lbs")) {
lineChild = srChild.ReadLine();
while ((lineChild = srChild.ReadLine()) != null)
{
string[] word = lineChild.Split(';');
Child c = new Child();
c.ChildID = int.Parse(word[0]);
c.Firstname = word[1];
p.Secondname = word[2];
foreach (Father item in Father)
{
if (item.FatherID == int.Parse(word[5])) p.Father = item;
}
Children.Add(c);
SelectedChildren = c;
}
srChild.Close();

WPF how to clear the texbox content in list view using MVVM

I am using below code and MVVM observable, but "Clear" button not clears the content of text boxes.
What I need to do here?
MainWindow.xaml
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="30*"/>
<RowDefinition Height="10*"/>
</Grid.RowDefinitions>
<Grid>
<ListView ItemsSource="{Binding Credentials, Mode=OneWay}">
<ListView.View>
<GridView>
<GridViewColumn Header="User Name">
<GridViewColumn.CellTemplate>
<DataTemplate>
<TextBox Text="{Binding UserName}" Width="100"/>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
<GridViewColumn Header="Password">
<GridViewColumn.CellTemplate>
<DataTemplate>
<TextBox Text="{Binding Password}" Width="100"/>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
</GridView>
</ListView.View>
</ListView>
</Grid>
<Grid Grid.Row="1" >
<Button Grid.Column="0" Content="Clear" Command="{Binding ClearTextBoxCommand}" Width="150"/>
</Grid>
</Grid>
MainWindow.xaml.cs
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
DataContext = new MyViewModel();
}
}
MyViewModel.cs
public class MyViewModel : INotifyPropertyChanged
{
private ObservableCollection<Credential> _credentials;
public RelayCommand ClearTextBoxCommand { get; }
public event PropertyChangedEventHandler PropertyChanged;
protected virtual void OnPropertyChanged([CallerMemberName]string propertyName = null)
{
var handler = PropertyChanged;
handler?.Invoke(this, new PropertyChangedEventArgs(propertyName));
}
public ObservableCollection<Credential> Credentials
{
get => _credentials;
set
{
if (value == _credentials)
return;
_credentials = value;
OnPropertyChanged();
}
}
public MyViewModel()
{
var data = new List<Credential> {new Credential {UserName = "user1", Password = "password1"}};
_credentials = new ObservableCollection<Credential>(data);
ClearTextBoxCommand = new RelayCommand(ClearTextBox);
}
private void ClearTextBox()
{
var data = new List<Credential> { new Credential { UserName = "", Password = "" } };
_credentials = new ObservableCollection<Credential>(data);
MessageBox.Show("clear done!");
}
}
public class Credential
{
public string UserName { get; set; }
public string Password { get; set; }
}

Credentials property has notification about change in setter:
public ObservableCollection<Credential> Credentials
{
get => _credentials;
set
{
if (value == _credentials)
return;
_credentials = value;
OnPropertyChanged();
}
}
so if you need to change that collection, use property, not _credentials field
not _credentials = new ObservableCollection<Credential>(data);, but
private void ClearTextBox()
{
var data = new List<Credential> { new Credential { UserName = "", Password = "" } };
Credentials = new ObservableCollection<Credential>(data);
MessageBox.Show("clear done!");
}

Using the Credentials property instead of _credentials field is mandatory. But you do not have to assign a complete new ObservableCollection. Just clear the old one and add a new Credentials object.
private void ClearTextBox()
{
Credentials.Clear();
Credentials.Add(new Credential { UserName = "", Password = "" });
MessageBox.Show("clear done!");
}

This is working at my Application

How can I use 2 data bindings for an ItemSource Data Template in WPF App

I have a counter which increments depending on a foreach Loop from:
public partial class UserControlCounter : UserControl, INotifyPropertyChanged
{
private int _scanStatusCounter;
public int ScanStatusCounter
{
get { return _scanStatusCounter; }
set { _scanStatusCounter = value; NotifyPropertyChanged(); }
}
public UserControlCounter()
{
InitializeComponent();
DataContext = this;
}
private async void Button_Click(object sender, RoutedEventArgs e)
{
await Task.Run(getAll);
scanStatus.Text = "Persons " + ScanStatusCounter.ToString();
}
private async void getAll()
{
//grab data and iterate it
string[] string_array = new string[] { "a", "b", "c", "d", "e" }; // type = System.String[]
foreach (var i in string_array)
{
ScanStatusCounter++;
await Task.Delay(100);
}
}
public event PropertyChangedEventHandler PropertyChanged;
private void NotifyPropertyChanged([CallerMemberName] String propertyName = "")
{
PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
}
}
and the Xaml:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="150"/>
<ColumnDefinition Width="auto"/>
<ColumnDefinition Width="auto"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="60"/>
</Grid.RowDefinitions>
<ListBox Grid.Row="0" Grid.Column="0" Name="myListBox" Height="40" ></ListBox>
<TextBlock Grid.Row="0" Grid.Column="1" Name="scanStatus" Height="40" Text="{Binding Path=ScanStatusCounter, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"></TextBlock>
<Button Grid.Row="0" Grid.Column="2" Click="Button_Click" Height="40">Click Me</Button>
</Grid>
That works fine and increments "live", but my problem is that I need to get that now running inside a more complex Data Template.
I've tried to inject the Counter onClick with:
private async void Button_Click(object sender, RoutedEventArgs e)
{
var btn = sender as Button;
var contentPresenter = (btn.TemplatedParent as ContentPresenter);
var ppStatusCounter = contentPresenter.ContentTemplate.FindName("scanStatus", contentPresenter) as TextBlock;
ppStatusCounter.Text = "Entrys found: " + ScanStatusCounter.ToString();
}
But then I get the Value only onClick not like a live incrementing Counter, that's my Data Template:
<UserControl.Resources>
<c1:NameList x:Key="NameListData"/>
<DataTemplate x:Key="NameItemTemplate">
<Grid Margin="2">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="auto"/>
<ColumnDefinition Width="100" />
<ColumnDefinition Width="100" />
<ColumnDefinition Width="100" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="40"></RowDefinition>
<RowDefinition Height="40"></RowDefinition>
</Grid.RowDefinitions>
<TextBlock Grid.Row="0" Grid.Column="0" Text="Domaine"/>
<TextBox Grid.Row="1" Grid.Column="0" x:Name="txtDomainName" Text="{Binding Path=DomaineName}" Margin="0,0,5,0"></TextBox>
<Button Grid.Row="1" Grid.Column="1" Width="100" Height="30" Margin="5,5,5,5" x:Name="btnNames" Click="Button_Click" Content="Start Scan" />
<Grid Grid.Column="2" Grid.Row="1" Height="20">
<ProgressBar x:Name="pbStatus" Height="20" Width="100" Minimum="0" Maximum="100" Visibility="Hidden"/>
<TextBlock x:Name="pbStatusText" HorizontalAlignment="Center" VerticalAlignment="Center" Text="Scanning" Visibility="Hidden"/>
</Grid>
<TextBlock Grid.Column="3" Grid.Row="1" Name="scanStatus" Text="{Binding Path=ScanStatusCounter, UpdateSourceTrigger=PropertyChanged}"/>
</Grid>
</DataTemplate>
</UserControl.Resources>
<Grid>
<StackPanel Orientation="Horizontal" VerticalAlignment="top">
<StackPanel Orientation="Horizontal" Margin="0,20,0,0">
<ListBox x:Name="lstDomainNames"
Margin="5,5,5,5"
ItemsSource="{Binding Source={StaticResource NameListData}}"
ItemTemplate="{StaticResource NameItemTemplate}"
IsSynchronizedWithCurrentItem="True"/>
</StackPanel>
</StackPanel>
</Grid>
that's my Data Source Class, not much there:
public partial class NameList : ObservableCollection<SetCredentials>
{
private static Logger logger = LogManager.GetCurrentClassLogger();
public NameList() : base()
{
using var forest = Forest.GetCurrentForest();
Forest currentForest = Forest.GetCurrentForest();
DomainCollection domains = currentForest.Domains;
foreach (Domain objDomain in domains)
{
Add(new SetCredentials(objDomain.ToString()));
}
}
}
public class SetCredentials
{
private string domainName;
public SetCredentials(string domain)
{
this.domainName = domain;
}
public string DomaineName
{
get { return domainName; }
set { domainName = value; }
}
}
Do I have to add a second Data Binding source to my ItemSource or do I need another approach for this, for example in my TextBox Binding?

Disable Itemscontrol components on button click

I'm learning wpf through mvvm.
My application consist of below logic.
Form which has a button that will add a selected components horizontally from Itemcontrol like textbox, combobox and rich textbox and a button whenever the button is clicked.
When the add button is clicked the specified set of components will be added in the line information dynamically.
2) Data will be inserted into the table after pressing the add info button.
3) The issue is after clicking the add info button, the components in the itemscontrol should be readonly. This is the place I'm struggling as of now.

So the question is how to disable/readonly the Line Information ,textbox and cpt on add info button click.

Dirty way would be adding a "global" bool property in your ViewModel and binding it to your Controls IsEnabled/ReadOnly Properties.

Get index of data binding from ItemsControl

Is there any way to get the index of the data which is binded to the ItemsControl, when a button is clicked?
<ItemsControl x:Name="ic_schranke" DataContext="{Binding Schranke}" >
<ItemsControl.ItemTemplate>
<DataTemplate >
<Button Height="80" x:Name="btn_open" Click="btn_open_Click" HorizontalAlignment="Stretch" Style="{StaticResource TransparentStyle}">
<Grid HorizontalAlignment="Stretch">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="1*"/>
<ColumnDefinition Width="2*"/>
<ColumnDefinition Width="1*"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="1*"/>
<RowDefinition Height="30*"/>
<RowDefinition Height="1*"/>
</Grid.RowDefinitions>
<Rectangle x:Name="rect" Grid.ColumnSpan="3" Grid.Row="1" Opacity="0.65" Grid.Column="0" Fill="#FFCEEAFF"/>
<Border CornerRadius="25" Height="50" Width="50" HorizontalAlignment="Center" Grid.Column="0" Grid.Row="1">
<Border.Background>
<ImageBrush ImageSource="/Assets/schranken.jpg" />
</Border.Background>
</Border>
<TextBlock Name="schranken_name" Grid.Column="1" Grid.Row="1" Text="{Binding name}" VerticalAlignment="Center" HorizontalAlignment="Center" FontWeight="ExtraLight" Foreground="Black" />
</Grid>
</Button>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
Here is the sample data which is binded to the IC:
List<Schranke> elements;
public UserPage()
{
this.InitializeComponent();
elements = new List<Schranke>();
for (var i = 1; i < 15; i++)
elements.Add(new Schranke() { name = $"Schranke NR:{i}" });
this.ic_schranke.ItemsSource = elements;
}
And here is the code in the button click event:
private async void btn_open_Click(object sender, RoutedEventArgs e)
{
Grid grid = (sender as Button).Content as Grid;
//Debug.WriteLine($"content {tb.Text} clicked");
var tmp_background = grid.Background;
grid.Background = new SolidColorBrush(new Windows.UI.Color() { A = 255, R = 78, G = 170, B = 44 });
VibrationDevice testVibrationDevice = VibrationDevice.GetDefault();
testVibrationDevice.Vibrate(System.TimeSpan.FromMilliseconds(150));
await Task.Delay(3000);
grid.Background = tmp_background;
}

Maybe something along the lines of this:
the presenter - put this in the data context
public class SchrankePresenter : INotifyPropertyChanged
{
private List<Schranke> _elements;
public List<Schranke> Elements
{
get { return _elements; }
set
{
_elements = value;
OnPropertyChanged("Elements");
}
}
public ICommand ClickCommand { get; set; }
private void OnPropertyChanged(string propName)
{
PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propName));
}
public event PropertyChangedEventHandler PropertyChanged;
public SchrankePresenter()
{
var elements = new List<Schranke>();
for (var i = 1; i < 15; i++)
elements.Add(new Schranke() { Name = $"Schranke NR:{i}" });
Elements = elements;
ClickCommand = new DelegateCommand(ClickAction);
}
public void ClickAction(Schranke item)
{
VibrationDevice.GetDefault().Vibrate(TimeSpan.FromMilliseconds(150));
}
}
public class Schranke
{
public string Name { get; set; }
}
the template:
<ListView ItemsSource="{Binding Elements}">
<ListView.ItemTemplate>
<DataTemplate>
<Button Height="80"
HorizontalAlignment="Stretch"
Command="{Binding ClickCommand}"
Style="{StaticResource TransparentStyle}">
<Grid HorizontalAlignment="Stretch">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="1*" />
<ColumnDefinition Width="2*" />
<ColumnDefinition Width="1*" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="1*" />
<RowDefinition Height="30*" />
<RowDefinition Height="1*" />
</Grid.RowDefinitions>
<Rectangle x:Name="rect"
Grid.Row="1"
Grid.Column="0"
Grid.ColumnSpan="3"
Fill="#FFCEEAFF"
Opacity="0.65" />
<Border Grid.Row="1"
Grid.Column="0"
Width="50"
Height="50"
HorizontalAlignment="Center"
CornerRadius="25">
<Border.Background>
<ImageBrush ImageSource="/Assets/schranken.jpg" />
</Border.Background>
</Border>
<TextBlock Name="schranken_name"
Grid.Row="1"
Grid.Column="1"
HorizontalAlignment="Center"
VerticalAlignment="Center"
FontWeight="ExtraLight"
Foreground="Black"
Text="{Binding Name}" />
</Grid>
</Button>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
you can do the background animation using a storyboard/visualstate
EDIT : regarding the DelegateCommand, it's a simple implementation I use for my WPF apps -
internal class DelegateCommand<T> : ICommand
{
private Action<T> _clickAction;
public DelegateCommand(Action<T> clickAction)
{
_clickAction = clickAction;
}
public event EventHandler CanExecuteChanged;
public bool CanExecute(object parameter)
{
return true;
}
public void Execute(object parameter)
{
_clickAction((T)parameter);
}
}

WPF Data Binding not showing

So I'm having what should be a simple XAML Data Binding error. I've got the below XAML with two classes (so far) that they used for DataBinding, a Row, which contains an ObservableCollection rows. The nodes have a bunch of extra associated information and I'm trying to show these nodes in a grid-like fashion (it's going to be used for a path-finding algorithm.)
The problem is that the "Here" TextBlock doesn't show up. But I know that the Nodes are getting bound properly because their values show up in the Debugging StackPanel.
<Window.Resources>
<local:Row x:Key="TestRow">
<local:Node x="0" y="0" Cost="20" />
<local:Node x="0" y="1" Cost="20" />
<local:Node x="0" y="2" Cost="20" />
</local:Row>
</Window.Resources>
<Grid Name="MainGrid" Margin="10,10,10,10" >
<Grid.RowDefinitions>
<RowDefinition Height="150" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="100" />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<StackPanel Margin="0,25,0,0"
DataContext="{Binding ElementName=AStarListView,
Path=SelectedItem}"
x:Name="Debugging" Orientation="Vertical" >
<TextBlock Text="{Binding x}" />
<TextBlock Text="{Binding y}" />
<TextBlock Text="{Binding Cost}" />
</StackPanel>
<ListView Grid.RowSpan="2" Margin="2,2,2,2" Grid.Column="1"
x:Name="AStarListView"
ItemsSource="{StaticResource TestRow}" >
<ListView.ItemTemplate>
<DataTemplate DataType="local:Row">
<ListView ItemsSource="{Binding nodes}" Width="48" Height="48" >
<ListView.ItemTemplate>
<DataTemplate DataType="local:Node">
<TextBlock Text="Here" />
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
Here's the (stripped) Node class.
public class Node : INotifyPropertyChanged
{
public Tuple<int, int> coordinates { get; set; }
public int x
{
get
{
if (this.coordinates == null)
return -1;
return this.coordinates.Item1;
}
set
{
if (this.coordinates != null)
this.coordinates = new Tuple<int, int>(value, y);
else
this.coordinates = new Tuple<int, int>(value, -1);
OnPropertyChanged("x");
}
}
public int y
{
get
{
if (this.coordinates == null)
return -1;
return this.coordinates.Item2;
}
set
{
if (this.coordinates != null)
this.coordinates = new Tuple<int, int>(x, value);
else
this.coordinates = new Tuple<int, int>(-1, value);
OnPropertyChanged("y");
}
}
private Node _parent;
private int _Cost;
public int Cost
{
get
{
return _Cost;
}
set
{
_Cost = value;
OnPropertyChanged("Cost");
}
}
protected void OnPropertyChanged(string propertyName)
{
if (PropertyChanged != null)
{
PropertyChangedEventArgs args =
new PropertyChangedEventArgs(propertyName);
this.PropertyChanged(this, args);
}
}
public event PropertyChangedEventHandler PropertyChanged;
}
Here's the Row class:
public class Row : ObservableCollection<Node>
{
public ObservableCollection<Node> nodes { get; set; }
public Row()
{
this.nodes = new ObservableCollection<Node>();
}

Here's the corrected XAML, the class definitions are correct in the question, need to replace "AStarListView" with this XAML.
<ListView Grid.RowSpan="2" Margin="2,2,2,2" Grid.Column="1" x:Name="AStarListView"
ItemsSource="{StaticResource TestRow}" >
<ListView.ItemTemplate>
<DataTemplate DataType="local:Node">
<Grid Background="#dddddd" >
<TextBlock Grid.Row="0" Grid.Column="0" Text="{Binding x}"/>
<TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding y}"/>
<TextBlock Grid.Row="1" Grid.Column="0" Text="{Binding Cost}"/>
<Grid.RowDefinitions>
<RowDefinition Height="24"/>
<RowDefinition Height="24"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="24"/>
<ColumnDefinition Width="24"/>
</Grid.ColumnDefinitions>
</Grid>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
My problem was that I had the ListViews too deeply nested. The inner ListView was binding to the "nodes" property of a Node, which didn't exist.
