I need to support cascading drop downs (select). I can easily do this with Telerik Blazor, but I'd like to stay as close as possible with the suite generated code.

if I stick with the default binding, the only way I could think of getting a message back from the createDto to load the municipalities was an event. none of this seems like a very good idea, that's why I'm posting here. Should I change my bindings on the select or do you have a better scenario to get municipalities to load when County is changed. the images should give you a better understanding. Thank you

    I should mention that the scenario does work up until CommunitiesAppService is alwasy null

    Hi,

    There is no need to use EventBus, it will increase your code complexity.

    See the document: https://blazorise.com/docs/components/select

    Select component has a SelectedValueChanged event, and you can use it.
