We just upgraded from Infragistics 9.1 to 9.2. I have a WebDropDown that was working on 9.1 that is no longer firing SelectionChanged server event all the time.
Here is what I discovered when debugging. If I had defaulted the WebDropDown's selected item to the first item in the list, and then click on another item on the list, the selectionChanged server event is not being fired. If I then click back on the first item again, and now click on another item, now the selectionChanged event starts to fire and work from that point on.
Also, if it happened that I didn't default the selected value to the first item, (i.e. any other item was defaulted for selection) then the selectionChanged event is firing correctly. (but of course there are times where you need the first item selected).
Any ideas?

Hi Pam,
Previously, the SelectionChanged event was fired always, no matter whether the new selection is the same as the old selection. This was updated to fire the event only when there is actual change in the selection. But i guess what you are describing is a little bit different - since in your scenario the new selection is different from the old one. I created a sample WebSite, using the latest Service Release build for 9.2 - 2003, and couldn't reproduce this. Please take a look at my example, and see whether you do it in the following way (it's attached) Maybe i am missing something.
Thanks for the feedback,
Angel
I too am having a similar problem after upgrading to 2009.2 SR 2056. We use the WebDropDown as a dynamic pick list for search for employees. You start typing an employees last name and it will auto-filter based on employee name pattern matching - what used to happen in 2009.1 when I selected one of the employees returned was that it would set the displayed text of the drop down to the full name that I selected, now in 2009.2 SR 2056 it only shows the text I have typed even though behind the scenes it has actually captured that I selected a particular item. I don't understand why this had to change or if something behind the scenes did not get upgraded when I use the project upgrade utility.
Any insight would be much appreciated.

This is a follow up to my original post - this issue involves selecting the first item returned in the result set - for example if I search for employees with last name "Thomas" and get back 4 matches, if I select the first item (full employee name) in the list the selected value text does not update to show the full employee name, only what I typed. However if I select the second item (employee) in the list, it does update to show the full employee name, then when I go back and select the first item it will update to show the full name. When I databind the result set during the async postback I explicitly set SelectedItemIndex to -1 so that no items are pre-selected as I have no idea what "Thomas" employee the user is looking for - I don't want to make any assumptions. Selecting the first item always updated the display text in the web drop down in 2009.1 but now in 2009.2 SR 2056 it does not.
i also have web combo issue in ie 8
i posted here, but no one is interested to answer:

i am using version 9.1.20091.2164
If you set AutoSelectOnMatch = false, it should work fine. In the meantime i will fix this shortly.
Thanks,
Hello Michael,
I have logged this behavior with our developers in our tracking system, with an issue ID of 34731 - "Server side SelectionChanged event handler is not raised when there is a selected item initially.". This development issue will be assigned to a developer to research for a fix,workaround, or other resolution. If some other resolution is reached, I will contact you with this information.
Thanks
Angel,
I notice a new Service Release was posted (build 20092.2120) mid-may - was this bug fix inluded?
Hi majensen,
This appears to be indeed a bug. It was introduced because selection is now not firing, hence the value is not being updated as well.
I will log it in our system and let you know when it's resolved.
Thank you,
