            {

                return true;
            }
            else
            {
                if (flag == true)
                {
                    return true;
                }
                else
                {
                    return false;
                }
            }


        }

the above two functions called by ribbon load only.i want to call the functions in button click functions.how to get Office.IRibbonControl control object value to call the Decrypt_Visible() in btn1_click function.

Answer 1

Just use ribbon.Invalidate() in btn1_click function. It calls getVisible (and other) callbacks for all controls.
