Combobox IsSearchable won't hold True value

[AaronRichardson]

I have a combobox that I copied from a demo app created by @mr-dang. For some reason, when I try to set the IsSearchable property to true, the property defaults back to false when I click out of the property box..

 

I've never seen a property behave obstinately like this. Any thoughts on what could be causing this? Here are the main settings on the combobox:

Hi @AaronRichardson ,

It is because the potential amount of items in your filter exceed the Delegable limit (500-2000) you have set and therefore the Search will not function.

Please click Accept as solution if my post helped you solve your issue. This will help others find it more readily. It also closes the item. If the content was useful in other ways, please consider giving it Thumbs Up.

Hi @WarrenBelz 

The source is a local collection and not yet connected to any external source... but that's good info to keep in mind!

I decided to try and create a new combobox and replicate all the settings manually. The new combobox works as expected, so I think this was a bug.

Thank you for your time!!
