<option value="0">--select--</option>
@foreach (var item in Countries)
{
<option value="@item.ID">@item.Name</option>
}
/**/

<InputText class="form-control" @bind-Value="CountryID" />
<div class="form-group">
<label class="control-label">State</label>
<InputSelect class="form-control" @bind-Value="StateID">
@if (States == null || States.Length == 0)
{
<option value="0">--select--</option>
}
else
{
<option value="0">--select--</option>
@foreach (var item in States)
