[CLOSED] [1.0] How to hide default trigger on ComboBox while allowing custom triggers to be visible

[mbb]

I need to create a custom trigger for a ComboBox that I need to use INSTEAD of the built in button. Basically I want no button to expand the ComboBox, but want a custom button that will launch a popup for a different reason.

I create the custom trigger like so in the Page Load event of the ComboBox:

            Dim trigger As New Ext.Net.FieldTrigger

            trigger.HideTrigger = False
            trigger.Icon = Ext.Net.TriggerIcon.Search
            trigger.Qtip = "Select User"

            Me.Triggers.Add(trigger)

I have tried to set the "HideTrigger" property on the ComboBox itself but then all triggers are invisible. I need only the built in one to be invisible.

This also needs to be done all in server side, no markup changes.
