AJAX Update Panel appears to also update Panel in other content area....

 I have to content areas, each with their own update panels.  I notice that whenever a partial page postaback is triggered in UpdatePanel2, a refresh is performed in UpdatePanel1.  The code does not use triggers to force the partial page postback.  The control in Panel2 is a textbox control that I assume by default causes the partial postback on a CR.  The control being refreshed in Panel1 is a DropDownList.

In addition, I have found that during a partial page postback for Panel2, Panel1 controls are being enabled unless I explicitly disable them.

Any ideas on why this behavior is occurring?

 What values do the UpdateMode properties have for the 2 update panels?

If the UpdateMode is set to Always for updatePanel then is normal to get a refresh when an update happens in update panel 2... Alway means you will get a partial update in you update panel at every postback. If you don't want this, set the UpdateMode to Conditional.


Hope this helps! - if not maybe you can post some code to see what you're doing.

 Hi Andrei,

 That was exactly the problem.  I set the UpdateMode to conditional in both panels and the issue was resolved!

Thank you for answering my post.

Having an issue using JavaScript to update an Update Panel with Multiple Update Panels
I am using JavaScript via the '__doPostBack' command passing in the 'ClientID' of my UpdatePanel to do a partial page postback.  This fires the UpdatePanel_PreRender event (or any other UpdatePanel event) where I run server side code. The actual partial page postback is working as expected, but since partial postbacks follow the full page lifecycle, ALL of my UpdatePanel events are firing which I do not want.  What ends up happening is the code in the other UpdatePanel '_PreRender' event is being called too which I do not want to occur. Is there a way aroun...
