Problem creating form nothing shows up in layout view or form view but it does in design view

When creating additional forms I have created a series of text boxes in design view.
When I select form view or layout view it comes up blank.
When I look at the form property sheet allow layout view and allow form view are both set to yes.
Your form's record source is empty, i.e. it contains no records. The form has no records to show and thus appears empty.
And it's either set to not allow adding new records, or the record source is read-only.

Create Child View based on selection in Drop Down List

I am using MVC 5 and I have the following situation:
I have a drop down list on a view that changes the child view that is displayed based on the selection in the list. This needs to change on the onchange or similar event. The selections in the list are populated from a database and has the following properties:
Link ID - Int (to be used as a value for the selection (must be saved on the main view)
Link Text - What is to be displayed in the drop down list.
LinK URL - The address of the child view action (made up of different areas, controllers, and actions)
In essence, when the list changes, it must call the URL (passing the model) and return the content to a targeted placeholder div on the page
Any Ideas on where to get started on this one?
We were able to get this working using ajax to call the child view. Thanks for the pointers.
