Does requiredvalidator suppport dropdown? I want to indicate that use need to choose a value in dropdown but I do not see validator working. Any advice is appreciated.
BTW these are dropdowns for foreign key entities that show description and not primary key.

<RadzenDropDown Data="@controlClassifications" TextProperty="Classification" ValueProperty="ClassificationId" Placeholder="Choose Classification" @bind-Value="@((newControl.ClassificationId))" Name="Classification" />

RadzenRequiredValidator Component="Classification" Text="Classification is required"
