A0.01 Non navigation aware components (Wpf) - chempkovsky/CS2WPF-and-CS2XAMARIN GitHub Wiki

In articles 07 through 99, we described how to create the basic components for our database and have a fully functional application. Let's compare the folder structures for Book and Edition entities.

folder structure

The folder structures are identical. This is because we created the same component sets for both entities.

  • eform is a component for Add, Update and Delete operation (it has three functional modes).

    • eform knows how to send and receive data to and from the backend node.
    • but eform has no UI to activate "save"-operation

  • edlg is a wrapper for the eform-component

    • edlg is a dialog
    • edlg has "Ok"/"Cancel"-buttons
    • when OK is clicked, edlg sends a notification to eform to make validation and submit data to the backend.

  • sform is a tabular form

    • sform knows how to send and receive data to and from the backend node for filtering and sorting
    • sform has select one item functionality

  • sdlg is a wrapper for the sform-component

    • sdlg is a dialog
    • edlg has "Ok"/"Cancel"-buttons
    • edlg is used by "SearchDialog" controls of eform component (last two slides of 66 article)

  • lform is a component that wraps eform and edlg

    • lform is a tabular form with CRUD capability

  • ldlg is a wrapper for the lform-component

    • ldlg is a dialog
    • ldlg has "Ok"/"Cancel"-buttons as select one item implementation

  • Additional component created for LitCountryView.

    • O2m component (articles: 56,57,58 and 68)
      • O2m is one-to-many tabular form
      • O2m has no dialog wrapper
      • CRUD capability can be turned on/off for master and detail table

All components mentioned above are non navigation aware. They know nothing about URL and routing.
