Property Value

bool bool

True if the control supports three states; otherwise, false. The default is false.


ToggleButton and can have three states:

checked@Windows.UI.Xaml.Controls.Primitives.ToggleButton.IsChecked?text= IsChecked **true**
unchecked@Windows.UI.Xaml.Controls.Primitives.ToggleButton.IsChecked?text= IsChecked **false**
indeterminate@Windows.UI.Xaml.Controls.Primitives.ToggleButton.IsChecked?text= IsChecked **null**

For the ToggleButton to report the indeterminate state, you must set the IsThreeState property to true.


ToggleButton has the same visual state for the indeterminate and unchecked states. Derived controls, like CheckBox, may define different visual states for each state.
