hi Allenp,

you can use show when condition . in that you can use showwhen: not(isnull(ri!data)) . try this onces when you have data then it will be show . apply this on which coloumn to hide

The reason I didn't suggest that is it looks as if they're checking specifically against a single space character (" ") versus blank. I suppose the view they're referencing for this record type could be set up so that it intentionally populates a single space instead of blank or null under specific conditions, though I guess maybe I should've asked about that assumption.

I might also add that using rule!apn_isNotBlank() may be better in this case since Appian sometimes does type conversion behind the scenes.

showWhen: rule!apn_isNotBlank(local!rowQueryResult[1].energy)

A normal query would work, I assume - can you share a screenshot / code snippet of the current configuration of the "data:" parameter of your grid? I can (hopefully) give more detailed advice upon seeing this.

Thanks Mike.

How do I load the query results into a local variable?

I believe you'll need to load the query results into a local variable first. Here when you're doing your "showWhen" check, I don't believe it's actually looking at the resulting data value (much less for a specific row, which in your case will always be row 1). After the data is in the local variable, you'd hardcode your "showWhen" to check that row, i.e.

showWhen: local!rowQueryResult[1].energy <> " "

It is being pulled from a SQL database into a RecordType.

I have tried this with no luck.

Gotcha. For the show/hide columns, you can probably just have the "showWhen" of the individual a!gridColumn() calls check whether that property of the data row is blank? This might depend on where you're storing the data that's used in the row, but this should be possible I'd think.

Yes, it will only ever have one row. The "compactness" is exactly why. I thought about just text boxes but just wouldn't look as clean.

So is this grid intended to only ever have one row? I guess I'm unclear why even use a grid at all, though i guess with that many columns it might offer you better "compactness"...

Yes, there was. Thank you

Was there supposed to be a picture attachment with this? If so, I don't see anything -- just in case you want to re-try that.
