Pass data between views in ExtJS - extjs

Question

I am reading data from store and populating main girdView. When any of the row is clicked, a windows appear and I want to fill the fieldset in that window with the same record which is clicked.
Can anyone tell me how to do it?
My popup window is like:
{
extend: 'Ext.window.Window',
height: 500,
width: 1500,
minWidth :1500,
maxWidth :1500,
layout: 'fit',
controller: 'PopUpWindowController',
initComponent: function () {
var me = this;
//console.log(me.myExtraParams);
var Store = Ext.getStore('mainStore');
Ext.applyIf(me, {
/* items: [{
xtype: 'form',
bodyPadding: 10,
region: 'center'
}]*/
});
me.callParent(arguments);
},
items: [
{
xtype: 'panel',
title : 'Projektierung',
bodyStyle : 'padding:5px',
width : 1880,
autoHeight : true,
items:
[
{
xtype : 'kopfdatenView', // Have to populate this view
}
]
}]}
and in Main view I am calling it as:
{
region: 'center',
xtype: 'gridpanel',
listeners : {
itemdblclick: function(dv, record, item, index, e) {
var extra = record.data;
win = Ext.create('App.view.PopUpWindow');
console.log(win.myExtraParams);
win.on('show', function(win) {
win.setTitle(record.get('ID'));
});
win.show();
}
},
columns: [
****
],
store: 'mainStore',
height: 100,
width: 400,
}
I want to populate fieldset in kopfdatenView. Kindly help

Answer 1

You directly pass your record to your window on creation :
win = Ext.create('App.view.PopUpWindow', {
myRecord: record
});
And then inside the window's initComponent function (before the callParent) :
this.title = this.myRecord.get('ID');

You can do something like this:
win = Ext.create('App.view.PopUpWindow', {
params: record
});
Then, in your PopUpWindowController you can retrieve 'params' in the render event (for example).
