    I'm populating my listview with some objects via linq (where\orderby) in the NeedsDataSourceEvent

    I then also have a textbox on the page for searching...when text is typed into the box, user clicks "search" which really just rebinds the listview and in needsdatasource I grab that textbox search value and bind on that.

    The issue I'm running into is when the user does a search filter and clicks a pager item, the entire thing re-binds with the full default datasource again...

    Is there some trick to this?

    Hi Steve,

    Unfortunately I'm unable to observe this unwanted behavior locally. I have attached a small test page, can you please take a look maybe I'm missing something obvious.

    All the best,

    Upopn paging, sorting, filtering, etc the needdatasource event will fire with a reason code of "2" = explicit rebind.  The only way around this is to use a datasource object control instead of this event and enable caching.  The datasource control will decide wether or not a new call is needed to the datasource.
