Selective Refresh of columns on list grid

[ypoovil]

Hello,
We have a requirement where the grid will be at bottom of a page and there will be a different screens above the grid which can be accessed by tabs.
I have 2 questions:
1)
In the first tab the grid will be populated with some data.
When the user moves to second tab then there will be input to the grid from that screen also .. the screen should retain all the existing data and also populate some cols in grid with the data from that screen.
This will be same when the user goes to another tab. It is like some columns in grid are mapped to some of the screens.
How do i achieve this ?


2)
At the same time is it possible to refresh some particular columns in the grid by some backend server side push….
If yes how to do it ?

(both the questions refer to the same grid)

1) It's a little strange (from a user experience perspective) to have Tabs affect a grid in this way - tabs usually switch to a different set of components. However, it is legal to provide the same component as tab.pane and simple make changes to it when the tabSelected event fires.

2) The SmartClient Messaging module supports HTTP streaming.
