Ah, posted it in the wrong place. I couldn't make it work properly. It simply wouldn't find the x:Type UserControl. It refused to bind, and I don't know how to fix it.

Hi,
I have a Datagrid, it is bound with an ObsevableCollection of ClassA which has two Properties Id, Name.
Up to here Datagrid works fine, now I want the selected row's Id value of Datagrid to be populated in the ViewModel.
Eventually this should be passed to another View where it will be used.
Can anybody please help me in achieving this, it is very urgent? Any help is appreciated, may be a link, a code snippet or even a suggestion helps me greatly.
Thaanks in advance.
Thanks,
Abdul Aleem

In your ViewModel, expose a SelectedItem property (of the same type as the entries in your ObservableCollection). Bind the SelectedItem property from your grid to this property in the ViewModel. When the selection changes in the grid, the underlying selection changes in the VM.

Hi All,
I have a WPF application named : TestWPFApplication, In that I have folders View and View Model. I have View class as below
namespace TestWPFApplication
{
public partial class MainWindow : Window
{
TestViewModel _testViewModel;
public MainWindow()
{
InitializeComponent();
_testViewModel = new TestViewModel();
DataContext = _testViewModel;
}
}
}
then I have ViewModel class as below.
namespace TestWPFApplication
{
public class TestViewModel : INotifyPropertyChanged
{
TestData _testData;
public TestSpecificCommand TestSpecificCommand { get; set; }
public TestViewModel()
{
_testData = new TestData();
_personNames = new ObservableCollection<TestData>();
this.TestSpecificCommand = new TestSpecificCommand(this);
}
private string _name;
public string Name
{
get { return _name; }
set
{
_name = value; NotifyPropertyChanged("Name");
}
}
private int _id;
public int Id
{
get { return _id; }
set
{
_id = value; NotifyPropertyChanged("Id");
}
}
}}
When I am trying to reference this ViewModel as static resource to bind properties of ViewModel to View then its giving error as below.

Any help please? I am not able to understand this, I have ViewModel in the same assembly as View and then I try to reference them using the same Assembly name and Name space name it says the ViewModel class is not available.
Any help is appreciated please help me.

It looks like your view and view-model are in the same assembly. Try removing the assembly from the XML namespace declaration:
<Window x:Class="TestWPFApplication.MainWindow"
xmlns:testns="clr-namespace:TestWPFApplication"

Does it give you an error message? Maybe something in the "Error List" or "Output" windows?

Hi Rick,
It says that the
The name "TestViewModel" does not exist in the namespace "clr-namespace:TestWPFApplication.ViewModel". \VBOXSVR\VMShared\Test Projects\TestWPFApplication\TestWPFApplication\View\MainWindow.xaml 9 9 TestWPFApplication
Thanks,

But according to the code you posted earlier, it's not in the TestWPFApplication.ViewModel namespace; it's in the TestWPFApplication namespace.
It sounds like you've put:
xmlns:testns="clr-namespace:TestWPFApplication.ViewModel"
instead of:
xmlns:testns="clr-namespace:TestWPFApplication"
"These people looked deep within my soul and assigned me a number based on the order in which I joined."

Hi Friends,
I have two Textboxes, One for Id and another for the Name, I need to pass both of these two into MyViewModel class Id and Name Properties in a Button Click, so far I am able to pass one of them to the ViewModel, how can I pass both the parameters to the ViewModel, any help is greatly helpful. Thanks in advance please.
So far I am able to do as below
in View
<Button Content="Save" HorizontalAlignment="Left" Margin="277,142,0,0" VerticalAlignment="Top" Width="74" Name="btnSaveSpecific"
Command="{Binding Path=TestSpecificCommand}"
CommandParameter="{Binding ElementName=txtName, Path=Text}" />
In the Command class
public void Execute(object parameter)
{
var values = (string)parameter;
this.ViewModel.AddAnItem(values);
}
In View Model
public void AddAnItem(string _name)
{
int t;
if ((_personNames == null) || (_personNames.Count() <= 0))
t = 1;
else
t = (_personNames.Count <= 0) ? 1 : _personNames.Max(x => x.Id) + 1;
_personNames.Add(new TestData(t, _name));
}
I want to change this AddAnItem to take two parameters int and string and if possible return value also, but return is not important, what is important is to take two parameters. Please need help, any sort of help a link or code snippet or even a suggestion also helps.
Thanks,
Abdul Aleem

Why? Just put two string properties in your ViewModel and binding your Text boxes to them. You can then read them from your command.

The condition in the company is to bind them from xaml but when I am trying to bind the ViewModel from xaml, I am getting value only if I bind one but when I am trying to bind the second one and try to raise NotifyPropertyChanged event then both the values are not coming inth xaml.
Then I tried add static resource of ViewModel in xaml, the ViewModel has the same namespace and assembly as xaml view file, its not letting me add the static resource of the ViewModel.
Without ViewModel is not being accessed as StaticResource I am not able to reference the ViewModels Properties in the View, its giving me compile error saying that ViewModel is not available in the namespace. I tried it many ways not not helping me out, I wrote the code as above question.
Anyhelp please.
Thanks,
Abdul Aleem

Without you showing your ViewModel and View here, it's impossible to say why it doesn't work, however I would take a guess that you aren't actually referencing the namespace in your XAML. Typically, I would expect to see something like this in your Window/UserControl header:
xmlns:vm="clr-namespace:MyApplication.ViewModelNamespace" Then you would reference this as such
<Window.DataContext><vm:NameOfViewModel></Window.Resources>

TestViewModel is not a resource, yet you are attempting to use it as though it is. Change your Window.Resources section to a Window.DataContext that looks like this
<Window.DataContext>
<testns:TestViewModel />
</Window.DataContext>

And that would be correct. Look at the code you posted. The ViewModel isn't in that namespace, it's in TestWPFApplication. The error was very explicit about what the problem was.

Thanks for all your help but I found the Problem that I was struggling with, it was because of the network drive I loading the Application path from. When we are using loading the static resources data context the UI can take them only if they from trusted source, my application was on network drive.
Thanks for all your support Pete and Rick, without you guys I couldn't have got this far. About my wrong code here I was changing the code all the time, may be pasted it when it was wrong. Thank you very much for that.

Your binding mode should be OneWayToSource not OneWay,
<TextBox Text="{Binding Name, Mode=OneWayToSource}" HorizontalAlignment="Left" Height="22" Margin="160,64,0,0" TextWrapping="Wrap" VerticalAlignment="Top" Width="120"/> Or TwoWay if you want your View and the property in your ViewModel to modify each other.

Hi All,
How can I add Dictionary into an ObservableCollection and when an Item is added to Dictionary then it will update the UI, I tried in all the ways but UI is not getting updated.
I even used ObservableCollection<tupple<int, object="">> to overcome of it, but still it is not updating the UI.
Can anybody please help me in that, any sort of help is appreciated. Thanks in advance.
Thanks,

You can't directly do this. The change notification has to come directly from the object that is changing so the dictionary has to raise the notification.
Have a search for an ObservableDictionary implementation instead. Here's one I found with a quick Google. ObservableDictionary<TKey, TValue> (C#) | Shimmy on .NET[^]
