My canvas app has gallery with current user filter. As long as there are records for the logged in user, there are no complaints. But when a user login for the 1st time, obviously there wont be any of his items in the gallery. For this 1st time user when there are no items in the gallery, i dont want to show him a empty gallery. I would like to display a message on screen "There are no submitted forms currently for you. Please submit a form by clicking on '+' icon above". How do I have this message available for new users and gallery items for old users on the same screen.

I have the same question (0)

@RameshMukka

You can hide the Gallery by changing its Visible property to this code

!IsEmpty(Gallery1.AllItems)

Then you can make a label with a custom message that appears when there are no records by putting this code in the Visible property.

IsEmpty(Gallery1.AllItems)

Do I have to hide other elements on the page as well? Like on my screen below, along with my gallery I have a rectangle, a label, an icon etc.

No, once the gallery is hidden everything else inside it will disappear as well. You only have to write the code in one place: the gallery's Visible property and it will take care of everything.

@mdevaney But my other controls are not shown within the gallery. They are outside gallery. Does gallery allow to have controls inside it?

@RameshMukka
I assumed you were talking about controls inside the gallery.

Yes, you must hide each one using this code in the Visible property

!IsEmpty(Gallery1.AllItems)

Re: Display custom message on screen when gallery has no records to return

@mdevaney I have a small problem here. There isnt any problem for the new user now. But for a user when there are gallery items the custom message pops up for a second or 2 before the custom message goes hidden and gallery is shown? How can I avoid this custom message to be shown for for a second or 2 when the gallery is not empty. Thanks a lot in advance.

Thanks,
Ramesh
