If this was causing a javascript error then it makes sense. The execution of the javascript would stop and prevent "return false" from being called.

Thanks for the reply.

I spent 2 hours yesterday around this and it took me 2 minutes today to realize that the JSON string in the responseText wasn't correctly built. Why was this causing a page refresh? Beats me.

Best regards.

Have you tried using an HTML button instead of an asp.net button? asp.net buttons have "__doPostBack" which is what's causing the postback.

XMLHttpRequest causing page refresh

Here it goes...maybe on of you has been here before.

Scenario:

-I have an ASP Web Application with a MasterPage that holds an iframe.

-On this MasterPage I have an UserControl that holds some ASP buttons that trigger, directly from javascript, some XMLHttpRequests to a ASPX for information refreshing.

Symptom:

- Each time the request is complete, the whole page gets refreshed.

Tests already made:

- Return false, in every method involving the pre and pos-request.

- Set UseSubmitBehavior to false in the buttons.

Any ideas?
