I am having a static region and having two sub regions as a tab slot…when i make any change and move to another subregion i need a pop up message forcing the user to save the data … As of now what I did was,I kept a confirmation in the button which I have in the second sub region but the problem is when the user dont make any change and move to the second sub region and press the button also this message will pop up..so instead I need this confirmation message when there is a data change in the first sub region
