WPF/C# Label Content to ComboBox

Question

I have a WPF/C# app with a tiny issue. I have a label that is passing the string value of AZ. I have a combobox that has AX, AY, and AZ values bound to the database. For some reason, the label value is not matching to the combobox value.

So, I have

CbCode.SelectedValue = Code;

Code is coming from another window

public SystemCode(string Code)
{
    InitializeComponent();
    Code = sysCode;
}

public string Code { get; }

The debugger tells me the string value is AZ, bu the combobox in the screen is the default the value of AX.

So how do I get the label content to set the page load value of the combobox?

XAML:

<ComboBox x:Name="CbCode" DataContext="{StaticResource CodeViewSource}"
SelectedValuePath="Code" ItemsSource="{Binding}" DisplayMemberPath="Code"
HorizontalAlignment="Left" Margin="106,103,0,116.4" Width="97"
d:LayoutOverrides="Height"/> <TextBox x:Name="TxtZipFive"
HorizontalAlignment="Left" Height="23" Margin="106,0,0,85.4"
TextWrapping="Wrap" Text="" VerticalAlignment="Bottom" Width="97"/>

您的问题还不够清楚，但我认为您需要使用：

UpdateSourceTrigger=PropertyChanged
