Hi all,

I just want to know if is it possible to hide and show canvas' graphics. I have a rectangle in a canvas serves as border of my display item. When i set the item visibility to false, I also need to hide that border.
How could I do that?

Forms does not address graphic elements, it only addresses items and their prompts. However, if you were to create an item that is wide but not very high and you gave it a black border it should look like a line. Give it a go and see what happens. Have you considered using a stacked canvas and when you don't want the items displayed 'hide' that canvas?

I did that but the new item is always on top. I don't know how to put that item as background. To solve this, I just make the old item as background and the new as my display item which serves as s status bar.

You are correct, you can't hide the canvas which contains the item which currently has focus. Therefore, move the focus first.

Try creating a new control item (or even a non-database item on this record) which lives on the OTHER canvas. Go to that item and then hide the unwanted canvas.
