Fields Required for All Gallery Items

[RachelPalya1]

Hi there, 

I have an application that sends meeting invites from a gallery (image below).  In the example below there are 12 items in the gallery, which will create 12 meeting invites in Outlook.  I am trying to disable the button until ALL of the values for the specified fields in the gallery are completed.  I am using the code below but it only applies to the 1 row and not the subsequent 11.  Any ideas on how to disable the submit button until the end user fills out 'TextInput1' and 'To_Box' for all gallery items and not just the first row?

Button DisplayMode = 
If(IsBlank(TextInput1) || IsBlank(TO_Box)
,Disabled, Edit)

Hi @RachelPalya1 ,

Try this - free-typed, but I think it is close to what you need.

If(
   CountRows(YourGalleryNames.AllItems) =
   CountRows(   
      Filter(
         YourGalleryName.AllItems,
         !IsBlank(TextInput1.Text) && !IsBlank(TO_Box.Text)
      )
   ),
   DisplayMode.Edit,
   DisplayMode.Disabled
)

I had to switch around the Edit and Disabled but it worked!! You rock, thank you so much!

I havent tested this but you can try.

Insert a label (label1)and hide it later inside the gallery.

Label1 text property: if(isblank(textinput1.text),0,1)

Next on your submit button display mode property...

If(sum(gallery.allitems,label1.text)=countrows(gallery.allitems), edit,disabled)
