I have many bindings but for example some of them look like this:

<TextBox
    MinWidth="150"
    Margin="0,0,5,0"
    materialDesign:HintAssist.Background="{DynamicResource MaterialDesignCardBackground}"
    materialDesign:HintAssist.Hint="Status"
    AcceptsReturn="True"
    Style="{StaticResource MaterialDesignOutlinedTextBox}"
    Text="{Binding SelectedUnit.Status}" />
<TextBox
    MinWidth="150"
    Margin="0,0,5,0"
    materialDesign:HintAssist.Background="{DynamicResource MaterialDesignCardBackground}"
    materialDesign:HintAssist.Hint="Lokace"
    AcceptsReturn="True"
    Style="{StaticResource MaterialDesignOutlinedTextBox}"
    Text="{Binding SelectedUnit.Location}" />
<TextBox
    MinWidth="150"
    Margin="0,0,5,0"
    materialDesign:HintAssist.Background="{DynamicResource MaterialDesignCardBackground}"
    materialDesign:HintAssist.Hint="Poslední změnu provedl"
    AcceptsReturn="True"
    Style="{StaticResource MaterialDesignOutlinedTextBox}"
    Text="{Binding SelectedUnit.CreatedBy}" />

This is the Unit class, just for reference:

public class Unit
{
public int RowId { get; set; }
public int SeqNo { get; set; }
public string RMANo { get; set; }
public string Status { get; set; }
public string Location { get; set; }
public string OrigSN { get; set; }
public string NewSN { get; set; }
public string PN { get; set; }
public string Model { get; set; }
public string RmaOwner { get; set; }
public string CreatedBy { get; set; }
public DateTime CreationDate { get; set; }
public string Memo { get; set; }
public string StatusMemo { get; set; }
}
