how to pass Model and a parameter to mvc action method?

The inputs must be inside of a form. The form element defines an action which is a URL where the browser submits the inputs. The input names must match the MVC action parameter property name.

I recommend going through a beginning level MVC tutorial to learn the basics.

I am new to mvc. still learning..
Here what i need is to pass the filepath from a list of uploaded files, without losing the model data entered on the page.

the action method has to return a view with model object, but that will clear the values previously entered on the page..

I want to delete file from the list, without losing state of the page

i didn't get the idea, how to solve this

Hi @shijo stephen ,
What have you done so far, maybe you can provide the code you are currently having trouble with.
After reading your question, I think you want to implement CRUD in MVC. You can study the following documents.
Examining the Details and Delete Methods

An action link is just an anchor. Clicking an anchor causes a get and only query string parameters are supported. The object passed to the action link can only have simple properties, no complex types.

If you need to a complex object, then create form, put all the model properties into hidden fields, and use a submit button instead of a link. The form can not be nested in another form, must be outside any other forms.
