Answer 1

Imagine that you have ModelView Class like below:

Public Class Test
{
    public int SelectedBloodGroup { get; set; }

    public IList<SelectListItem> AvailableBloodGroups { get; set; }
}

Then You Should Fill AvailableBloodGroups in your model in HttpGet of your Controller.

So you should have this in your View:

 <div class="col-md-8">
    <select asp-for="SelectedBloodGroup" asp-items="Model.AvailableBloodGroups">"AvailableBloodGroups"</select>
 </div>

Then with Http Post post your form to your controller and SelectedBloodGroup is then value that User Select it.

use this also in your string to use value

$"where bloodGroup = {model.SelectedBloodGroup}"
