Hiding / disabling the UltraCombo drop down button
posted

Hi,

I would like to hide the drop down button on the UltraCombo.  Yes I know it would basically be a text box at that point, but that is what I want.  If it is not possible to hide the drop down then maybe someone can tell me how to disable the button or change the button graphic.

Here is why:

There are cases where there are 250,000 records if I don't filter the list.  I would like to make it so the user has to type a certain number of characters (let's say 4) before the query is issued that will populate the combo.  This allows me to add a where clause to the query so it returns faster (hits an index and returns less rows).

So I don't want the user to see the drop down, try to click it before we have populated the combo.  I want them to type 4 characters first, then populate the combo, drop the list and show the first item in the list that matches their 4 typed in characters.

 

Thanks

Randy
