Issue with Combo Box Not Showing Items

Posted on by WiranataLim

I have issues with combo box not showing items on the first appearance.

I have the Head of Department combo box visible if the Request Type choice is "ADV". The Head of Department is not showing the choice items when first time it is visible.

I have to navigate to another screen first and go back to the previous screen for the combo box to work properly.

I have tried another workaround to collect the choices into a collection on the "OnVisible" property of the screen and changing the combo box "Items" to that collection. But it is not working.

Appreciate the help!

Hi WiranataLim

Can you please supply the Items, DefaultSelectedItems and DisplayFields of the Combo Boxes. If the Items are a collection, when and how do you collect it ?

Hi WarrenBelz,

Here are the requested properties for your reference.

The Items are not a collection. I populated it directly from a data source.

Thanks!

hey

i think this is a general issue. i created a new choice column in sharepoint and added it to the app. at first when i collapsed it no values were there. but after a few minutes it fixed itself without me modifying anything.

cheers

Hi WiranataLim

Try with a Classic Combo Box - Modern controls are still in preview and really should not be used in production apps presently.
