Hello Raghu,
that is possible of course. For that you don't even need navigation via a router, because your IconTabBar is on a single XML view. It is enough to set the selected key of the IconTabBar after you press the button on the first IconTabFilter (SAPUI5 SDK - Demo Kit).
Regarding the "value transfer". You can either determine the value from the first tab using the respective getter method and set it on the second tab with the respective setter method. Or you define a binding to the same model property (e.g. in a JSON Model) for both fields.
Regards,
Florian
