I want to change the property of a dropdown box, so that it is originally disabled when I open a form page, but when I change the value of another preceeding dropdown-box it should be enabled and also mandatory so that user is forced to enter additional data. Is this possible? I checked the documentation and the forum but did not find something similar...
You can set Disabled to check if the selection from previous DropDown is not null. For example: Disabled="@(CustomerID != null)". You will need also required validator: https://blazor.radzen.com/requiredvalidator
