How to set checkbox.isChecked without raising event
One way would be to detach the event handler, set the IsChecked property, and then reattach it.
myCheckbox.Checked -= myCheckbox_Checked;myCheckbox.IsChecked = true;myCheckbox.Checked += myCheckbox_Checked;
You could use the Click event instead of Checked and use the state of the checkbox like below:
private void normalCheck_Click(object sender, RoutedEventArgs e){ if (normalCheck.IsChecked ?? false) { normal(); }}Then, this event won't be raised by using normalCheck.IsChecked = true;. It will only be raised by a click.
NOTE: The null-coalescing operator (??) is necessary because IsChecked returns a bool? type which could be null.
If you're referring to changing the checked status without raising the "_Checked" event, you will likely have to override the event handler with a param to tell it to skip the event or not.
