How can I set my TextBox text as the value in the App.config file

my App.config:

<appSettings>
    <add key="Hours" value="12"/>
    <add key="Minutes" value="00"/>
  </appSettings>

How can set the value of Minutes as the TextBox text and make it update whenever the value of Minutes update

<TextBox x:Name="Minutes_Top" Text="00"/>

I tried adding this Line in the top:

xmlns:properties="clr-namespace:_10KHours.Properties"

And add this line in the TextBox

Text="{Binding Source={x:Static properties:Settings.Default}, Mode=OneWay}"

But it didn't work, the text is "_10KHours.Properties.Settings"

I want that the text In Minutes_Top will be 00 like the value in the App.config and change when the value change (when The value in the App.config change or the text change so the App.config value will be change)

@faikyldrm thank you, but it's not helping me, I need this in xaml not c# – Raz Luvaton Jul 24 '17 at 11:50
You haven't specified a Binding Path. – Clemens Jul 24 '17 at 11:55
@Clemens It's not duplicate because the answer there didn't helped me – Raz Luvaton Jul 24 '17 at 12:00
Let me repeat myself, you haven't specified a Binding Path. `Settings.Default` is the settings object. It has properties that you can bind to. – Clemens Jul 24 '17 at 12:10
@Clemens Thank You, So what should I do? – Raz Luvaton Jul 24 '17 at 12:19

Bind to one of the properties, of course! By specifying a Path, e.g. Path=Minutes. – Clemens Jul 24 '17 at 12:20
@Clemens This isn't working - `Text="{Binding Source={x:Static properties:Settings.Default}, Path=Minutes, Mode=OneWay}"` – Raz Luvaton Jul 24 '17 at 12:21

You have created the application settings in a wrong way. Use Properties->Settings in your Visual Studio project. – Clemens Jul 24 '17 at 12:23
