I am trying to configure a combo box to accept 1000 items. There are now three versions of combo box controls, Old Classic, Modern and Modern Modern (although this is a dropdown so maybe not equivalent).
My question is: Can I get the Modern combo box to search my items beyond 500
Set up:
- I have increased my delegation to 2000. My list has ~1200 items sorted alphabetically by code. The codes begin with "a" and go all the way to "y"
- The collection has two fields "code", "name"
- I want to start typing the first letters of the "code" and have the search narrow my options
- Modern Modern dropdown - If I click into the dropdown the list opens. I can start typing "a" and the second "a" item on the list will be selected. If I continue typing "a", I will move down the list. I had to put in a "clear" button because there was no way to deselect an item. The list is only the first 20 items. I can't even get into the "b"s. This control is a bust, for now anyway.

- Modern control. This one is a little better. I can get down to the "l"s and there is nice quick filter as I type. And a tab accepts the selection. I CANNOT get to the "y"s. In this case, I can only get to the 500th item regardless of delegation. I was looking for a property in this control that I could use to filter the list to the value I typed in the control (like SearchText) but there isn't a property here. So this control is a bust.

- Old classic. What a beast! It is difficult to get this control to look congruent with the other controls in model driven app but it seems to have a nice search and even a couple layouts for list display. It's usability is clunky and I am suspicious of its performance on load but I think it is my only option because I can actually get to the "y"s of my list.

Does anyone have any suggestions for the modern control or am I stuck using the classic?
