There is no implemented flag or the right event to detect, if the input comes from a user (by keyboard and mouse)?
Depending on the CombobBox Item and a ListView selection, different pages are loaded in a frame and the selection of the ComboBox is saved. So i would have to encapsulate the page loadings. Usually there was a SelectionChangedCommitted in WinForms which would make it easier.
I can't find something. I thought maybe
SelectionChangedTrigger
could be something, but I don't see any difference between
Always
and
Committed.
ComboBox Class
In WPF, there is no specific event or flag to detect if an input comes from a user or not. One way to achieve this is to handle the SelectionChanged event of the ComboBox and check the Source property of the SelectionChangedEventArgs. The Source property will tell you which element raised the event, and you can use this to determine if the event was raised by the user or programmatically.
Here is an example of how you can handle the SelectionChanged event and check the Source property:
private void ComboBox_SelectionChanged(object sender, SelectionChangedEventArgs e)
if (e.Source is ComboBox)
// The event was raised by the user
// The event was raised programmatically
