Hello,
I am using the untiy runtime binding with Unity 2023.3.0a6 and I’m trying to bind a dropdown.
So far I was able to bind the choices list and the index, changing value in code reflects change in UI.
The problem I have is that selecting something in the dropdown does not change the index value.
I thought it would be caused by a default binding-mode being wrong so I switched to TwoWay but it does not seem to have any effect.
Is this achievable through binding or am supposed to register to a change event ?
Thank you !
Hi @SebMaire , when an item is selected from the dropdown menu, it should go through the value property of the DropdownField, which should in turn notify that the index has changed. The notification should be fired only if the underlying index actually changed.
Can you check what happens in the PopupField<T>.value property when you select the item? The work should happen there.
If the notification is not fired up, please report a bug with a repro case so that we can investigate.
Thanks!
Had a quick look and there is indeed a bug in the property, we’ll get it sorted.
Thank you for raising it up!
Edit: Link to the issue.
