WPF Checkbox check IsChecked

Question

I'm not talking about an event handler for this, but rather a simple If Statement checking if the CheckBox has been checked. So far I have:

if (chkRevLoop.IsChecked == true){} 

But that raises the error:

Cannot implicitly convert type 'bool?' to 'bool'. An explicit conversion exists (are you missing a cast?)

Is there a way to do this that I'm missing?

Answer 1

You can use null coalescing operator. This operator returns right-hand operand if the left-hand operand is null. So you can return false when the CheckBox is in indeterminate state (when the value of IsChecked property is set to null):

if (chkRevLoop.IsChecked ?? false) {  }
