Hi Ondrej,
Thanks for contacting Syncfusion support.
We are unable to reproduce the "StateChanged and
StateChanging event not called" in the SfSwitch control. We have prepared
a sample for your requirement and please get the sample from the attachments.
In the sample, we have used two SfSwitch control and called the State changed
and changing events. We have hooked the display alert box on the events.
Please check and let us know the details. If still, you
have an issue please let us share the modified sample with replication steps. It
will help us to provide the solution the earlier.
Thanks,
Vijayakumar Viswanthan
