PowerApps checkbox not updating in scroll container

Hi everyone,

I am trying to check or uncheck the checkbox on the powerapps custom page. I am passing the values to the powerapps custom page through JS on click of the button on the model driven app. The structure is Vertical Container >> Child Container >> Checkbox control. The data binding is successfully done, checked by added the text box on the page. So based on custom logic, the value passed is true only but checkbox does not show that it is checked. When I try to check the checkbox then also it does not get checked, however, I click on the checkbox once and then scroll up or down, suddenly the checkbox is checked. Weird.

Even if I hard code "true" value to the "Checked" property for the checkbox, still the same issue so definitely not the data binding issue. Checkbox is not checked but if I try to click and scroll up or down then shows the checked checkbox.

Please help. Thanks.

After scrolling up or down

It sounds like you're encountering a rendering or refresh issue with the checkbox control in your Power Apps custom page, possibly due to the vertical container's scrolling behavior or a bug in the modern checkbox control.

Try these steps:

set the checkbox's `Reset` property to a variable (e.g., `locResetCheckbox`) and toggle it (`UpdateContext({locResetCheckbox: !locResetCheckbox})`) in the `OnCheck` or `OnSelect` property to force a refresh when clicked.

Ensure the vertical container's `Vertical Overflow` is set to `Scroll` and check for any conflicting `Flexible Height` or `Align` settings on the child container that might affect rendering.

If the issue persists, test with a classic checkbox control instead of the modern one, as some users report persistent bugs with modern controls. You could also add a timer control to delay the checkbox state update by 0.5 seconds to ensure proper rendering.

Hi,

I had tried all other things already but did not work. And finally tried the classic controls and worked. Thanks.

@SS-28040912-0,

There is an ongoing issue with the Modern Check box control (https://community.powerplatform.com/forums/thread/details/?threadid=a91ce410-4927-f011-8c4e-7c1e5266971b)

Kindly rollback to the Authoring version 3.25042.10 it will work.
