MudSelect: Changing the bound Value does not fire SelectedValuesChanged event and does not perform required check

Component

Component name

MudSelect

What happened?

There is a list of strings in a MudSelect. If I change the value of the variable bound to MudSelect, the value is changed but the SelectedValuesChanged event is not fired and also the required check is not executed.

Expected behavior

SelectedValuesChanged event is fired and the required check is performed.

If I use the MudSelect<T>.SelectOption() method based on the reference to the MudSelect, the SelectedValuesChanged event is fired and the Required check is also performed.

Reproduction steps

1. Select a value by Button "Select this Item by binded value" => No Event Fired Messge appears.
2. Clear the select field => The Required-Check is performed and the Event Fired Message is displayed.
3. use the button "Select this Item by binded value" on more time => No Event Fired Messge appears. => The Field is still marked as required. The Required-Error-Message is displayed
4. Using the Button "Select this Item by ref-Object" sets the value to the selected one and the Event Fired Message is displayed.

Could be a similar problem as in #2852.

Hi. We are just stuck on this problem. It is very annoying. Is there any workaround for it?

[henon]

@MooWeek Does it annoy you enough so you maybe try to fix it and PR?

Running into this issue now as well. I don't have the time to submit a PR. Bummer was hoping most of these issues would have been resolved in MudBlazor by now. I agree with @henon that we need more contributors. I ended up using CodeBeamExtensions

It seems this issue is fixed? - If you need to use "SelectedValuesChanged" then you have to use "SelectedValues" in place of "@bind-SelectedValues".
