I have two drop down boxes (by index).
I have two screens in same view and these two drop down boxes are present in box the screens (same view but different tab strip).
Based on the data entered in the first screen, the dropdown box should have value A or B as default in .
drop down has two values. (A and B). By default A will be shown.
If field A (input field) is updated in screen 1, the drop down button in screen should have 'X' as default value.
If field B (input field) is updated in screen 2, the drop down button in screen should have 'Y' as default value.
How to change the default value.
