How to prevent old data in Model from being passed into the input fields automatically?-CodePudding

Is it possible to prevent the data from being automatically passed to the input fields. For example - if I have an edit page where I want to change the data and I want the user to type the data again without giving him the pre-filled old data. I was looking over some documentation about the ModelState and the asp-for tag but I just couldn't find the answer.

I was looking for help and I found this post here. Well I want to do exactly the opposite.

asp-for tag helper functionality_

EDIT: I tried to change the value attribute of the input field to empty string and it worked, however I still would like to know if there is an asp.net approach.

CodePudding user response：

If you don't want to pass data from action to Edit view,you can return a view with an empty model like this:

public IActionResult Edit()
        {
            return View(new YourModel());
        }

Or you can try to use id and name attribute to replace asp-for,so that the data will not be binded to inputs.Here is a demo.

Change

<input asp-for="TestProperty" />

<input id="TestProperty" name="TestProperty" />
