I have a Group on Page. The group needs to show some content based on Blob field value.
So this is what I want to do:
Visible = Rec.Blob.HasValue();
// some other stuff here.
Visual Studio Code tells me that:
Rec.Blob.HasValue() - procedure calls is not valid for client expressions. This warning will become an error in a future release.
How do I set this kind of group visibility in other way, so I don't get this warning...? As far as I know it's the only way I can hide/show this group dynamically.
