Ax2012 Useful functions 2

Show viewhistory on form datasources if you have ValidaTimeState Enabled DateTime enabled on the tables of that form. 
create this method in Global class so you can call whereever you want in form button click as below.

void clicked()

{
    buttonHistoryClick(element, this);
    Super();
}

            if (formDataSource.validTimeStateAutoQuery() == _from && new DictTable(formDataSource.table()).isValidTimeStateTable())
