Display button

Question

Hi, 
 Underneath the grid, display a button. The button should be disabled by default. If any changes are made to the grid (i.e. if a row is added, a row is removed, or data entered for a row is changed), the button should be enabled. After the button is clicked, it should become disabled again. Any help will be appreciated.

You could create a displayButton local variable. Any change made to the grid that you described should have a 'saveInto' parameter into which you can toggle that displayButton local variable. Upon clicking the button, you can have that saveInto reset the local variable to the default state.
