Hi Giovanni Zangrossi,
Greetings from Syncfusion.
Query: Need to change the SelectedIndex only when the picker is closed.
We analysed your query and currently the SelectedItem and the SelectedIndex will get changed on changing the selection in the picker itself. So, we have work-arounded to meet your requirement by using the custom picker.
We have prepared a sample by using a custom picker. In the sample, we have created a “PickerSelectedIndex” property in the custom picker class and we have used this property to store the current selected index value while closing the picker in the “Closed” event. For your use, you can use the "PickerSelectedIndex" property instead of “SelectedIndex” property in your sample to achieve your requirement. Please find the sample from the below link.
