Property Value

true if three-state check boxes; false for two-state


Check boxes can be either two-state (with true and false) or three-state (with true, false, and indeterminate). Indeterminate check boxes indicate that the condition is neither true nor false. For example, if some selected text is bold and some is not, a Bold check box might be indeterminate, to show the mixed state.

You can specify check box pictures for all the states using the Picture property. Specify text for the states using the TextIndeterminate, TextFalse, and TextTrue properties.
