Using a variable to filter a Two Option set in CDS

[Dr_David_Banner]

Hi 

I'm new to PowerApps so please bare with me. 

I'd like to filter a Gallery based using a variable

My app is using the CDS with various field types, some of which are Two Option sets. I've figured out how to filter based on the Two Option set data type, but I can't figure out how to use a variable as part of the item property of my gallery.

This is the basic filter:

Filter(Alerts, Acknowledge = 'Acknowledge (Alerts)'.Yes)

I'd like to use a variable to set the value I filter on though, for example: 

Filter(Alerts, Acknowledge = 'Acknowledge (Alerts)'.VAR1)

the example variable command doesn't work, can anyone help? 

thanks in advance

Hi @Dr_David_Banner ,

You just need to reference the Variable like this

Filter(
   Alerts, 
   Acknowledge = VAR1
)

Thanks Warren

I tried this originally, but I get an error saying the datatype doesn't match, because I am using a "Two Option set" . I can change the filter to say 

Filter(Alerts, Acknowledge in "VAR1")  

which does work but, "in" is not a supported delegated lookup with the CDS so its not very efficient and may cause me issues down the road

thanks

Hi @Dr_David_Banner ,

I was only using your code in the correct syntax. You are correct with the Delegation issues with the In Filter, although this is a separate issue from using a variable to filter in general.

I am not a CDS user, but I would have thought the syntax would be

Filter(Alerts, VAR1 In Acknowledge) 

I found this post that may be useful for you.

Thanks, I'll use the in function for now, perhaps there isn't a more efficient way of doing what I am after
