Hello,

 

Maybe someone encountered this issue before... I have a dataverse table in which there is a single choice column. When I try to display this in gallery through modern control - dropdown box I get a list of my choices but it won't read from dataverse - I mean a specific one chosen job which is done on other screen. I have already some records with choices made and this gallery supposed to read it but it won't. Does anyone know why? 

 

As You can see no values chosen here:

...but I can see choices in dropdown:

    Hi @marcy_pi ,

     

    May I ask if the data you have saved after you choose in the First Screen, because we noticed you said it cannot read the choice from the Dataverse.

     

    We create a Dataverse for testing to understand better.

    We insert a Gallery for Choose the Mercy to simulate a specific one chosen job which is done on another screen.

    In this Gallery you can Choose All choice from the column.

    The Items of the DropDownBox:

    Choices([@ForDisplays].Marcy)

    vhanytianmsft_2-1687836951655.png

     

    The OnChange of the DropDownBox:

    Patch(ForDisplays,LookUp(ForDisplays,Name = ThisItem.Name),{Marcy:Dropdown1.Selected.Value})

    The AllowEmptySelection of the DropDownBox:

    True

    We insert the Second Gallery on another screen to read the choice which we have already choose.

    Choices([@ForDisplays].Marcy)

    vhanytianmsft_6-1687836951661.png

     

     

    The Default of the DropDoenBox:

    ThisItem.Marcy

    vhanytianmsft_7-1687836951667.png

     

     

    The AllowEmptySelection of the DropDownBox:

    True

    Hope this will help you.

     

    Best Regards,
