I saw a similar question, but mine is the opposite. I want the user to be able to enter into the combobox
so I have my UltraCombo as DropDown. Here's my problem. I have a BeforeDropDown event inside which I go to the database and load a datatable. Than I bind that datatable to the UltraCombo datasource. As soon as the DropDown Box opens, the current value is blanked out. Even though the current value exists in the list that was loaded. Anyone else having these problems
The Combo should not blank out in DropDown style, even if the item does not exist on the list.
What version are you using?
Can you create a small sample project demonstrating this?
I still see this behavior in Infragistics 10.2. BeforeDropDown sets the DataSource and right after DataSource is set the Value is still preserved. However, sometime later the internal DoDropDown method seems to clear it.

Oops, sorry about that. I misread the code.You are right, this does seem like a bug in that case.
I'm going to forward this thread over to Infragistics Developer Support so they can create a case for you and look into this issue more thoroughly.
Hi Mike, thanks for looking into this. I'm afraid, though, that it is a bug. What you're saying is correct if the combo was, in fact, using DropDownList style. But if you look at the sample, you'll notice that it's specifically set to DropDown style. So the value can be anything.
