Forms and Razor Pages Throws Exceptions

[Andy]

Are Razor Pages supported by the Forms widget.  I keep getting an unhandled exception caught in the middleware after the Exception Handler has completed and nothing is returned just the <div></div> that I placed around it

Hello Andy,

The Form can be used in RazorPages. Attached you can find a sample RazorPages project, in which a Form is initialized.

Hi Ivan, thanks for the reply. 

A key thing in allowing the form to be rendered was the .FormData(TModel model) call.  Without it there's nothing on the screen.

However the next issue is the Post call - its returning an error 400.  I would assume that since the form values will be passed using a [BindProperty]  then the signature of my method should be:

    IActionResult OnPost()

Digging deeper I've found that the post is failing due to the anti forgery token not being passed in.  With the Grid component all I had to do was add a .Data("forgeryToken") method.  Is there a similar method for Form?

 

Thanks,

Andy
