Hello,
I have a WebCombo control bound to a DataSet. I am manually initializing the WebCombo datasource after 3 characters are provided using a method to retrieve a DataSet.
The WebCombo is initializing the datasource just fine - I am able to type into the Person WebCombo and it properly filters the results as I type.
I am running into problems, however, after postback. On postback, the value of the WebCombo is reset to "Jane Doe" every time. What must I do to assure that my WebCombo SelectedRow/Value isn't lost upon Postback?
--------------
Attached are 2 samples. Please look at the wcPersonName web combo, as that's the one I am having problems with.
In my second attempt (Links2.aspx), I also implemented WebFlyPostbackManager. This resolved the problem of the SelectedRow changing upon postback (since there is no full post back), however after a button click, or any other postback, I get the error message that the Server Returned No Content
Please advise
I am unable to run your sample because I don't have some resources such as database. FYI, I am able to replicate the issue at my end. It only occured when AutoQueryHandler set to false. I have forwarded this to our developer teams. Also, about FlyPostBackManager issue, It will persist if your current page links into another page or there are some incorrect settings. Please look into our WebFlyPostbackManager sample for more informations.

Hello Alex,
I am sorry for the late response and also please ignore my previous post.After done some investigation, your scenario is not a bug. This happen because you use AutoQueryHandler as false.This condition similars with LoadOnDemand scenario (programmatic).If you ever have our old WebCombo such as WebCombo2, you should notice that you would need additional code to persist the text or value during FullPostBack.
I attached a simple sample to help your scenario.
