How to preserve a datepicker value?

So i have a daterpicker. I was asked to make the datepicker remember the date it was given when you were using it to search for a date. The codes:

[BindProperty, DataType(DataType.Date)]
        public DateTime Date { get; set; }

    <form method="post" asp-page-handler="TestClick">
        <br />
        <br />
        <input type="date" data-val="true" data-val-required="The Date field is required." id="Date" name="Date" value="yyyy-mm-dd" />
        <button>Search</button>
        <br />

    </form>

from a .cshtml file

public void OnPostTestClick()
        {
            String testDate = Request.Form["Date"];
            Debug.WriteLine("Testclick verdi2 = " + testDate);
            filterdato = testDate;
            ListData();
        }

from .cshtml.cs file

I was told where the code should probably be, but I don't know how to do it. IS there anyone that could help me to figure this out?

Use an input tag helper for rendering the date input. The following is all you need:

<input asp-for="Date" />

See more about working with dates and times in Razor Pages forms on my site: https://www.learnrazorpages.com/razor-pages/forms/dates-and-times

Also, you don't need to reference Request.Form. You can rely on Model binding to bind the posted value to your Date property:

public void OnPostTestClick()
{
    Debug.WriteLine("Testclick verdi2 = " + Date);
    filterdato = testDate;
    ListData();
}
