Nested IsBlank and IsEmpty

[Brendan_Hager]

Hi everyone...

I am trying to handle the following; if there is no item selected in a gallery, display the first item in an edit form. I've accomplished that with the If statement below. If the gallery is empty though, I want the edit form to display something like, "No Data."

Can someone guide me on how to incorporate what I believe should be an IsEmpty function in to the below expression?

If(
IsBlank(Key_Gallery.Selected),
First(Key_Gallery.AllItems
),Key_Gallery.Selected
)

If a gallery has any items in it, then there will *always* be a record selected.  

For a label that shows "No data", just add a label and then set the Visible property to:

   CountRows(Key_Gallery.AllItems)=0

I hope this is helpful for you.

Thanks @RandyHayes. This did the trick. I added the If statement because the App I inherited is laggy. Without it, we were seeing the app get hung up on, "Getting your data..." at times.
