Hello Water,
I tried the approach that you are currently using and it seems to work properly.
Here is a video, demonstrating the behavior at my end, when the
StartsWith(2) is used. I noticed that you are using
requestItems
function. Had you enabled the LoadOnDemand functionality? In this case, I would suggest you to implement the filter at server-side, like demonstrated in our
online demo here. Passing the currently typed text in the input of the ComboBox, you could then easily filter the query returned for your datasource, like demonstrated in the SourceCode of the referenced demo (Product ComboBox).
