Linked to the ViewModel TextBox . I'm running. I type the text into it, press the "Save" button, well, or another. And the text that I entered is not saved. Put a checkpoint on the event when data is sent to the model. As long as the cursor blinks in TextBox , the data in the VM is not sent, even if I press the other buttons on the form. You need to click in another TextBox field to transfer data.

 <TextBox Height="110" Text="{Binding Comment, Mode=TwoWay}" TextWrapping="Wrap"/>

How to force it to transfer data when I pressed the button?

    Try installing from Binding

     UpdateSourceTrigger=PropertyChanged

    The data in the VM will be updated immediately, without waiting for the loss of focus.
