Greetings new to Power Apps Canvas. We got a supporting Microsoft list with two lookup columns. Created a Power Apps Canvas for the user interface. Use the Canvas to publish a new record to the list. Question is; how to have each dropdown reset/clear the other. So, if the user selects an option from the first dropdown it would reset/clear the second dropdown and vice-versa.

So as shown in the image, if Exterior List Item is selected first and then Interior List Item is selected the Exterior List Item dropdown clears and vice-versa.

Any suggestion are greatly appreciated. TIA

Write this OnChange of DataCardValue4 property: If(DataCardValue4.Selected.Value<>Blank(),Reset(DataCardValue6),false)

  • Thank you blini ! Prefect result, I was caught up trying; IF(! IsBlank(DataCardValue4.Selected.Value),Reset(DataCardValue6),false) and even trying the keyword Not instead of the ! – Benny H. Mar 30 '22 at 23:10
