C# checkbox .Checked xaml?

Question

Programming

Hello,
you can somehow force the checkbox not to change state if the function has not been executed,
processing the click programmatically cannot change:
public void chkEv(object sender, RoutedEventArgs e){
CheckBox cb = (CheckBox)sender;
cb.Checked = true;
here comes the error Error CS0079
The event 'ToggleButton.Checked' can only appear on the left hand side of += or -=
if so how?

Answer 1

Checked is an event.
The state can be set with the IsChecked property :

CheckBox cb = (CheckBox)sender;
cb.IsChecked = true;
