How can I retrieve the configuration values in a MainViewModel system
In WPF I have created a form "Configuration.xaml" to enter the configuration values of my program. It contains a DevExpress "Hamburguermenu" control so that, when clicking on each menu option, different subforms appear, such as "Configuration_General.xaml", with the corresponding TextBox and ComboBox values.
The DevExpress "Hamburguermenu" control introduces the different menu options using the "MainViewModel.cs" system.
"Configuration.xaml" contains a "Save" button that starts the subform "configuracion_save.xaml" which is where there is a process that must collect the TextBox and ComboBox values from each subform in order to store them in a file.
The problem is, I don't know how to retrieve the TextBox and ComboBox values from each subform in order to save them.

Re: How can I retrieve the configuration values in a MainViewModel system
In WPF, the xaml is bound to a data model. You would retrieve values from the model (not from the xaml). Search google for "wpf mvvm examples".
Re: How can I retrieve the configuration values in a MainViewModel system
This case is different because the .cs are entered inside the Hambuguermenu control.
I open the form by:
// Configuracion Form. Open().
dynamic FrmFormulario = new Name_MainWindow_Configuracion.MainWindow_Configuracion();
FrmFormulario.ShowDialog();
And I can ask for FrmForm, but I don't know how to ask for something like: FrmForm.Form_HamburgerMenu.ItemsSource [1] .User_TextBox.Text

Post the question to the DevExpress forum.

Is not possible to post in DevExpress because License is required.

How are you developing without a license?
Re: How can I retrieve the configuration values in a MainViewModel system
The license costs $ 2,199 per year. I don't have a job and I entertain myself doing programs. cleared up !!
