BeginFormSitefinity and BeginForm

  • BeginFormSitefinity and BeginForm
  • Dear sirs,

    we are building a custom widget to allow mailing list Subscription using (Feather MVC widget)

    If we use BeginFormSitefinity (in the view) the action in the html does not evaluate to the correct path and is not routed to the widget controller

    If we use BeginForm everything run fines.

    Could You please elaborate about that behavior?

  • Hi Francesco,

    Would you please try to use the conversion structure of the widgets as described in the following articles:
    Create custom models, controllers, and views
    Create a “Hello World” MVC widget in a separate assembly

  • Hi Svetoslav,

    the widget is working fine and to build that I already followed the examples/instructions from the link you posted.

    The problem is only related to BeginFormSitefinity and BeginForm

    When I use BeginFormSitefinity in the view, the postback is not routed to the widget controller...
