ASP.NET Core Razor Post "Value" and "Text" from ddl

I want to update User Roles by using a select and post it to db. The select is working fine for RoleName but when I change or add a role, the RoleId has to be updated too. How do I do that in Razor pages?

With the below code only the RoleName is updated, for RoleId I get error because its valuue is null

UserRoleClassName = await _context.Roles.Select(a => new SelectListItem
{
Value = a.Id.ToString(),
Text = a.Name
}).ToListAsync();

class="col-3">
for="RoleName">Role Name
"Role" class="form-control" asp-for="AppIdentityRole.Role" asp-items="Model.UserRoleClassName">

"RoleId" asp-for="AppIdentityRole.RoleId" class="form-control" value="@Model.UserRoleClassName" />

Resolved. I used a jquery as below
$(function assignData() {
    $('#ddlRole').change(function () {
        $('#RoleId').val(this.value);
        $('#Role').val($(this).find('option:selected').text());
        return false;
    })
});
