C#/WPF: irregularities in textbox values when transferring datagrid row to child-window

Hello!

Please see below image for reference:

Messed up window — ImgBB[^]

This is my WPF window; "LicenseHolderProfileWindow".
Something fishy is going on when I'm trying to bind the TextBoxes.

I made a phony profile, to show you what's happening. For the first seven TextBoxes, the binding works perfectly. But for the four last, it gets messed up.

- 'Kontonr.:'-textbox gets the value from 'Tlf.:'.
- 'Kontakt:'-textbox is left empty.
- 'Tlf.:'-textbox gets the value from 'E-post:'.
- ...and 'E-post:'-textbox gets the value from 'Kontakt:'.

I checked the XAML, and I can't see anything out of the ordinary for any of the TextBoxes. They look like this. No typos. Nothing.:

XAML
<TextBox
    Name="txtKontakt"
    Canvas.Left="464"
    Canvas.Top="164"
    Width="180"
    Height="24"
    VerticalContentAlignment="Center"
    IsReadOnly="True"
    Text="{Binding Kontakt, Mode=TwoWay}"
    FontSize="14" />


...and I've set the DataContext as such:

XAML
d:DataContext="{d:DesignInstance Type=viewmodel:RidelHubMainViewModel}"

What I have tried:

I've gone through the XAML, looking for discrepancies or irregularities. Found none.

Might be difficult to answer without seeing the rest of my code, but is this a known issue, and are there any obvious things I could do to try to rectify it?
Where could I have messed up?

Thanks!

Can you show us the complete XAML file as well as the properties from your ViewModel?
Flidrip 23-Jun-21 9:23am    
Hello @TheRealSteveJudge. Appreciate your response.
Properties, that'd be the getters/setters, right? I have those in a Model, called LicenseHolder, a holder class. They are like so:
public int ID { get; set; }
public string Foretaksnavn { get; set; }
...and so on.
I create an ObservableCollection referencing them, in my ViewModel, like so:
public ObservableCollection<LicenseHolder> LicenseHolders { get; set; }.
The DataGrid is bound to it like so: ItemsSource="{Binding LicenseHolders, Mode=OneWay}". For this parent-window, the DataContext under <window> is the same as for the child-window: d:DataContext="{d:DesignInstance Type=viewmodel:RidelHubMainViewModel}".

I must admit, MVVM is new to me. Coding in general, fairly new also.
Hopefully my explanation made sense!

Updating my question with complete XAML-files, as requested.
TheRealSteveJudge 23-Jun-21 10:01am    
You should assign fallback values to your text boxes e.g. Text="{Binding Tlf, Mode=TwoWay,FallbackValue=Tlf}, so that you can see if the text boxes are at the right positions. I assume that you assign the wrong values in your ViewModel
Flidrip 24-Jun-21 8:26am    
Hi TheRealSteveJudge. Good insight. I did that, and as you suspect, the issue remains, and no trigger of the fallbackvalues.
I am going to have to dig through the code a bit, but I really don't understand this. What more is, a separate issue, when I add a new row, it adds TWICE. So might be some mixup related to that.
