That's what I needed, thank you!

Hi,

Thanks for attaching the sample code. I looked at it, and I think this happens because you have AutoPostBack=true. In that case for any Value or selection changed on the client, it will do a full postback.

If you set AutoPostBack to false i think it will work as expected. On the other hand, if you need to postback on selection changed you can set this specific autopostback flag :

           <AutoPostBackFlags SelectionChanged="On" /> (it can also be set to Async) 

Hope this helps,

I got it working by changing the filter type to client.  I don't understand something still though.  When I type a letter in the web drop down, it posts back several times.  When I have it set to Server filtering, it posts back 3 times when I type each letter.  I assume, given my code, it is losing the value due to those post backs.  Can you look at the included code I have?  Am I doing something incorrectly here?

Hi,

 Could you take a look at the sample i have attached - WebSite63.zip - It uses the same scenario that you describe, and it works fine, maybe you have some additional code or property set that introduces this wrong behavior.

Please let me know whether i can help further. 

Thanks,

ddPersonList.DataSource = objPersonCore.ReturnPersonList(

)
ddPersonList.TextField = "FullName"
ddPersonList.ValueField = "PersonID"
ddPersonList.DataBind()

I check the SelectedValue both on an update panel and also when they click the save button.  I have tried both Server and Client filtering.    Without fail, if the page loads and I scroll to find my name without typing, I get the correct SelectedValue.  If I use the filter type ahead, I get 0 every time.
