Question

I am using Visual C# Studio 2010 Express and I have oakward problem. I wanted to bind few TextBoxes to application Settings. I’ve followed Paul Sheriff’s solution Paul Sheriff’s solution. It works only in visual designer – I can’t run the app, cause i got:

XmlParseException ‘Provide value on ‘System.Windows.StaticResourceExtension’ threw an exception.

How is it possible, that it’s working in visual designer (values are presented in TextBoxes correctly) but there is a XmlParseException?

App.xaml:

<Application.Resources>
    <ObjectDataProvider x:Key="odpSettings" ObjectType="{x:Type setts:Settings}" />
</Application.Resources>`

The setts namespace is defined as xmlns:setts="clr-namespace:DbCopier.Properties"

My view:

<TextBox
    Text="{Binding Source={StaticResource odpSettings}, Path=Default.DbName}"
    Width="150" />

I got it!

The InnerException was pretty damn confusing. It’s all about the Property Scope in Settings file. I’ve noticed it was changed to Application, so it was read-only. I just changed it to User so it became writable. So easy and yet – so annoying mistake.
