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.

C# Master Detail View - Reverting unsaved changes

I'm creating CRUD application in C# with Caliburn.Micro and I have some Master Detail View that looks like that:
What i want to achieve is, when i make some changes(for example i change capacity from 47 to 50), and then select the other place, let's say Place 4 and select Place 5 again my capacity will be 47, not 50 like it is now.
I was thinking about OneTime binding, and manually firing binding to the viewmodel then, but viewModel should not have been aware of the view, so that seems like a bad idea. My code below.

WPF doesn't know Normal properties. You either have to make it a dependency property, or in your case, your VM has to implement INotifyPropertyChanged. when the value changes it will automatically updated.
May be you didn't applied INotifyPropertyChanged property for SelectedPlace_Capacity.
I think that this is the issue.

WPF MVVM properties binding not working properly

I have created a view model which has a single property for a student model, that I am then binding to a control in my XAML. But nothing is appearing when I execute the application.
I am setting data context in my app.xaml.cs as follows:
protected override void OnStartup(StartupEventArgs e)
{
base.OnStartup(e);
Registrationformusinemvvm.MainWindow window = new MainWindow();
VMUser VM = new VMUser();
window.DataContext = VM;
window.Show();
}
Why is the binding not working?
This is my view model:
public class VMUser:BaseClass
{
private student _currentStudent;
public student CurrentStudent
{
get { return _currentStudent; }
set {
_currentStudent = value;
OnPropertyChanged("CurrentStudent");
}
}
}
My Student model class:
public class student:BaseClass
{
private string name="sumit";
public string Name
{
get { return name; }
set { name = value; OnPropertyChanged("Name"); }
}
private int rollNum;
public int RollNum
{
get { return rollNum; }
set { rollNum = value;OnPropertyChanged("RollNum"); }
}
private int phNum;
public int PhNum
{
get { return phNum; }
set { phNum = value;OnPropertyChanged("PhNum"); }
}
private string sub;
public string Sub
{
get { return sub; }
set { sub = value;OnPropertyChanged("Sub"); }
}
}

My guess is that your binding isn't working because your _currentStudent is null by default. Initialize your _currentStudent if null.
public student CurrentStudent
{
get { return _currentStudent = (_currentStudent ?? new student()); }
set
{
_currentStudent = value; OnPropertyChanged("CurrentStudent");
}
}

You need to add OnPropertyChanged in your model class.
void OnPropertyChanged(string prop)
{
if (this.PropertyChanged != null)
this.PropertyChanged(this, new PropertyChangedEventArgs(prop));
}
public event PropertyChangedEventHandler PropertyChanged;

As per your above code you cant assigned the value to CurrentStudent Property so
can you please check do you have the value to CurrentStudent property.
Thank you for your question

Is not updated selected item on listview (wpf mvvm) if field of item changed

I'm writing my first program with the use wpf and mvvm.
Have a problem, that in the case of changes data in fields of selecteditem, selecting a new item becomes impossible.
If add to listview attribute SelectionMode="Single", then if many times try pick item, exeption:
The element with the same key has already been added.
image: https://www.dropbox.com/s/ey7izl19803uuhc/1.png
If this attribute is removed, then pick another item, simply does not occur.
Image: https://dl.dropboxusercontent.com/u/32438899/2.png
If the data has not changed, the navigation works fine.

In viewmodel problems can not be. It is very easy, PropertyChanged called whenever necessary.

WPF display content based on treeview selected item

I was able to retrieve selected item value from my treeview. Now I want to change the content in ScrollViewer control based on that value. I'm trying to display property values of Facility object which contains Containments which contains Tanks.
I'm new to programming sorry if my explanation is not clear enough.
Thank you.

I think what you want to do is display informations in a UserControl which will contains a grid with differents controls like textblock and textbox.
So you are going to create a new UserControl named FacilityView and FacilityViewModel and the FacilityView will contains a grid with ur Facility Ojbect property
First of all, I would create an property in MyWindowViewModel called
private Facility currentFacility;
public Facility CurrentFacility
{
get{return currentFacility;}
set{ currentFacility = value ;
notifyPropertyChange("CurrentFacility")
}
In your MainWindowsView (xaml)
<DataTemplate DataType="{x:Type localAdder:FacilityViewModel}">
<localAdder:FacilityView />
</DataTemplate>
<UserControl Grid.Row="1" Grid.Column="2"
Content="{Binding CurrentFacility,Mode=TwoWay,UpdateSourceTrigger=PropertyChanged,NotifyOnSourceUpdated=True}">
</UserControl>
And in your SelectedItem you would
if (selectedItem is Facility)
{
CurrentFacility = new FacilityViewModel(selectedItem as Facility);
}
Sry for the bad indentation im not use to this writing code.
EDIT2:
Okay, you have 2 choice, first of all u can create a BaseViewModel which will implements INotifyPropertyChanged.
FacilityViewModel : BaseViewModel
TankViewModel : BaseViewModel
ContainmentViewModel : BaseViewModel
This way you will change CurrentFacilityViewModel to CurrentBaseViewModel
private BaseViewModel currentBaseXXX;
public BaseViewModel CurrentBaseXXX
{
get{return currentBaseXXX;}
set{ currentBaseXXX= value ;
notifyPropertyChange("CurrentBaseXXX")
}
And in your SelectedItem you would
if (selectedItem is Facility)
{
CurrentBaseXXX= new FacilityViewModel(selectedItem as Facility);
}
if (selectedItem is Tank)
{
CurrentBaseXXX= new TankViewModel(selectedItem as Tank);
}
if (selectedItem is Containers)
{
CurrentBaseXXX= new ContainersViewModel(selectedItem as Containers);
}
Options2
You would have 3 current so
CurrentFacilityVM
CurrentTankVM
CurrentContainerVM
And in your SelectedItem you would
CurrentFacilityVM = null;
CurrentTankVM =null;
CurrentContainerVM =null;
if (selectedItem is Facility)
{
CurrentFacilityVM = new FacilityViewModel(selectedItem as Facility);
}
if (selectedItem is Tank)
{
CurrentTankVM = new TankViewModel(selectedItem as Tank);
}
if (selectedItem is Containers)
{
CurrentContainerVM = new ContainersViewModel(selectedItem as Containers);
}

You can dynamically Load the data template based on Type. Refer the below. You can toggle the template by change the instance of the SelectedItem to a Different class.
<Window.Resources>
<DataTemplate DataType="{x:Type entities:Facility}">
<Grid>
<TextBlock Text="{Binding FacilityName}" />
</Grid>
</DataTemplate>
<DataTemplate DataType="{x:Type entities:Containment}">
<Grid>
<TextBlock Text="{Binding ContainmentName}"/>
</Grid>
</DataTemplate>
<DataTemplate DataType="{x:Type entities:Tank}">
<Grid>
<TextBlock Text="{Binding TankName}"></TextBlock>
</Grid>
</DataTemplate>
</Window.Resources>

</Grid.RowDefinitions>
<ScrollViewer Grid.Row="0" Grid.Column="1" Margin="5" VerticalScrollBarVisibility="Visible" DataContext="{Binding SelectedItem}">
<ContentControl Content="{Binding }"/>
</ScrollViewer>
<Button Content="Save" Grid.Row="1" Grid.ColumnSpan="2" Grid.Column="0" Width="60" Height="25" Margin="0,0,5,0" HorizontalAlignment="Right"/>
