Controls disappear during development

[rodneyjoyce]

Hi,

My app has a hidden popup screen that is shown with a variable and visibility when I click on a button on the main form.

During development, half of the controls (buttons and the checkbox and some labels) disappear when I Preview it. It makes it VERY hard to debug and dev.

If I PUBLISH the app, it seems to work fine. This is obviously not a solution as I cannot publish the app every 5 minutes during my Dev cycle to test it. 

Here's a screenshot of the popup window in a published version (apologies it is under NDA so many things are blurred out)

and then here is the SAME popup window when previewed during Development. The Red boxes indicate the missing controls.

The z-order is correct (the Popup is at the very front) and all the controls have their Visible property set to the same field - I am convinced it is a PowerApps bug.

Thoughts?

Hi @rodneyjoyce ,

Do you mean that some of your controls disappear when preview?

I've made a similar test but not met the same problem like your description.

Here's my test for your reference:

1)I create a popup window based on your layout:

a Rectangle, three labels, a radio, two buttons

2)Group these controls together

 Please notice the controls' order and fill.

They may be covered by each other.

3)insert a button to make the popup window display/disappear.

set the button's OnSelect:

Set(var,!var)

 set group1's Visible: var

Then if I click the button , the popup window will display. If I click twice, the popup window will disappear.

All the controls are changing together.

(Both my preview mode and running mode, the app works good.)

If your problem still exists, please show me your settings about these controls and the button to make them visible.

Actually, I think your key problem is about order and fill. Please check these firstly.

Best regards,

@v-yutliu-msft I have similar issue. My control works in studio and preview but it doesnt work once published.

I have experienced this on complex screens with many controls. Oddly, repositioning the whole 'pop-up' (not the individual controls within it) resolved the issue.

It was very strange - like if there are too many controls layered over each other (with some marked as visible=false) PowerApps gets confused and doesn't render them properly. The control that was not rendering (a button) was the top-most element (z order). When moving the 'pop up' group either the whole button would appear or not appear, it was never a case that it was partially hidden.
