This demo has methods:

Code: Select all

    // gets the checkbox value
    function GetCheckBoxValue(const CheckBoxName: String): Boolean;
    // sets the checkbox value
    procedure SetCheckBoxValue(const CheckBoxName: String; Value: Boolean);
    // occurs when a checkbox is clicked

This document can be stored not only in RVF but also in RTF.
Only one additional setting is needed to make checkboxes work after reloading from RTF: RichViewEdit1.RTFReadProperties.BasePathLinks = False. With this settings, hyperlink targets are saved and loaded as they are.
