single exposed filter for two displays in same view

Question

I have three displays in same view. Every display has exposed form filter and in every pages ajax was set yes. How to use a single exposed filter for these three displays in same view?

I placed these three displays in to three quick tabs. For example, the three quicktabs names are test1, test2, test3. If I apply filter in test1, it should apply all other displays (test2, test3) also.

Answer 1

1. Under Advanced > Other You have to set the "Use AJAX:Yes" for both the views.
2. At the Quick tab setting page select the following radio button - Yes: Load only the first tab on page view".
