Good morning!
 
I built a Power App from SharePoint List to collect data with/from the app. 
 
I have two dropdown columns with 2 options and another dropdown column(single selection) with 4 options.
 
Low Profile
 
Yes
No
 
Fill Size
 
2 in
3 in
 
Dice Design
 
Std Style
Enc Style
Low Profile
No Style
 
I made default value selection for Low Profile to Yes and Fill Size to 2 in
 
DefaultSelectedValues
 
{Value:"Yes"}
 
and 
 
{Value:"2 in"}
 
(1.) With that I also want to set Dice Design dropdown value to be autoselected as Low Profile. How to do that?
_________________________________________________________________________________________________________________
 
 
(2.) And after that I have to make a rule if user try to change Fill Size to 3 in, it should show Information Pop-Up - 

Low Profile requires 2 in Fill Size. Changing to 3 in Fill Size will remove the Low Profile. If you want 2 in Low Profile, you MUST re-select that option(Low Profile).

 

________________________________________________________________________________________________________________

(3.) Then when the user hit ok to the Information, 

Then Low Profile should be changed to No as Fill Size is changed by Customer to 3 in.

 

OR if user hit cancel, means I want to keep same Low Profile(yes), Fill Size(2 in). It should not make any change.

    For Issue1, you could set the Default property for DropDown control.
    For Issue2&3, you will need to create a component like Confrim Dialog which will proivde two button Yes, No for user to select, and then handle the logic based on different options.

    Thanks you @Meekou for helping.
     
    I used Switch Function to filter out values and it worked for me!
