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.
We are using version 9.1
I created a workaround by saving the current value in the BeforeDropDown Event and than In AfterDropDownEvent, restoring the value. There are several other events like Leave, KeyUp, KeyPress that I am handling in my code. I've isolated the problem to the BeforeDropDown event by commenting out the other UltraCombo events.
