have a good time

How can I save the form values as a string after the page is redirected?

I use a static variable, if the number of users on the site increases for example 20000, will the site have problems?

Which method is better?

1. Using a static variable?

2. session?

3. Cookies?

4. ViewBag?

5. View State?

6. sql server database?

Actually, There is no the best method, Only the most suitable method. The methods you list above all have their own most suitable use cases.

From your comment, I think you may wanna redirect to another page with a string parameter, So you can try to use :

return RedirectToAction("actionName","controllerName",new { Name="xxx"});

It will send a get request: acontrollerName/actionName?Name=xxx.

Or, if you wanna save that string value for a long time, You can also try to use Session or Database. But one thing you need to consider is that you need to set the session time out according to the actual situation of your project.

no i dont want to redirect to other page i want give string value after refresh current page How can I save the form values as a string after the page is refreshed?

this is my model:

public int ID { get; set; }
public string Name { get; set; }

static variable:

public static int IDWordsaver = 0;

On Get for MyPage:

public async Task<IActionResult> OnGetAsync()
        {
            await LoadAsync();
            return Page();
        }

private async Task LoadAsync()
        {
            if (IDWordsaver != 0)
            {
                var SetRecord = _db.Table.FirstOrDefault(u => u.ID == IDWordsaver);
                ID = IDWordsaver;
                Input = new InputModel
                {
                    Name = SetRecord.Name
                };
            }
        }

i use this button for select one record from data base:

<button asp-page-handler="SelectMenu" name="selectedid" [email protected]  formnovalidate>Select</button>


public async Task<IActionResult> OnPostSelectMenu(int selectedid)
        {
            var selected = await _db.Table.FindAsync(selectedid);
            ID = selected.ID;
            Input.Name = selected.Name;
            IDWordsaver = selectedid;
            return RedirectToPage("MyPage", new { IDWordsaver });
        }
