I have coding in the TabControl page under ON CHANGE to test if a certain field is filled. If the field is not filled it gives a message like:
"The Event Date needs to be filled"
then it returns to the original tab.
My problem is when it returns to the original tab it repeats the message because the ON CHANGE is working again. How can I either prevent the second message or is there a way that it will not even let you click the other tabs until certain fields are full.. I guess, if possible I can disable the other tabs until the fields are complete?
