Get ID of AutoCompleteBox that caused postback

[Danny]

I have two autocomplete boxes on the page, and per the demo I'm setting their datasources in the Page_Load event. 

I only want to hit the database once, however.   How can I get the ID of the control that initiated the postback?

I've used:

String control_id = Page.Request.Params.Get("__EVENTTARGET");

However, it returns an empty string- I imagine that's because it's a parital postback.

Hello Danny,

You could get the control which initiated the callback with slightly different approach from the demonstrated one :

String control_id = Page.Request.Params.Get("__CALLBACKID");

However, since the control works upon callbacks it should have a constant access to the underlying datasource (database).
