Make sure panel 1 has an id or itemId assigned to it. In the click handler of your button (or controller action) do an Ext.Viewport.down('<Panel ID Goes Here>').RefreshFunction().

Keep in mind. Every panel, container, button, link etc.. you see in your app... lives in your browsers DOM. As long as you can get a handle to it (by way of an ID or ItemID or other css queryabile attribute) ... you can do something to it.

Hope that helps
John

Dear Boston Merlin,

Please help me out

.down() search for an itemId, Your Viewport need to be referenced in the controllerer and then you can try:

var MyViewport = this.getMyViewportRef();
MyViewport.down('#MyPanelMapItemId').RefreshFunction()

I tried everything.
But it is still not working.
My panel ID is mappan. so when I do

Ext.Viewport.down('mappan').RefreshFunction();

.
it is still showing the same error. Please help me. I am stuck on this for a ling time.
Uncaught TypeError: Object function constructor() { return this.constructor.apply(this, arguments) || null; } has no method 'down'
