},
deselectRow: function(){
console.log('deselectRow-1');

Man you're doing it wrong!
You can't use the Controller Reference to place a controller action.
Instead use the same CSS-like selector of your grid.
All functionality must be in your controller. The controler action (this.Control) will bind the function with the event.
Your controller must look like this:
Ext.define('ImpPdf.controller.GridControl', {
extend: 'Ext.app.Controller',
refs: [
{
ref: 'GridV',
selector: 'grid'
}
],
selectRow: function(rowmodel, record, index, eOpts) {
console.log('Foo');
},
init: function(application) {
this.control({
"grid": {
select: this.selectRow
}
});
}
});
In your view just eliminate the business code.
Ext.define('ImpPdf.view.MyViewport', {
extend: 'Ext.container.Viewport',
requires: [
'Ext.grid.Panel',
'Ext.grid.column.Number',
'Ext.grid.column.Date',
'Ext.grid.column.Boolean',
'Ext.grid.View',
'Ext.toolbar.Paging'
],
initComponent: function() {
var me = this;
Ext.applyIf(me, {
items: [
{
xtype: 'gridpanel',
title: 'My Grid Panel',
store: 'GridStore',
columns: [
{
xtype: 'gridcolumn',
dataIndex: 'string',
text: 'String'
},
{
xtype: 'numbercolumn',
dataIndex: 'number',
text: 'Number'
},
{
xtype: 'datecolumn',
dataIndex: 'date',
text: 'Date'
},
{
xtype: 'booleancolumn',
dataIndex: 'bool',
text: 'Boolean'
}
],
dockedItems: [
{
xtype: 'pagingtoolbar',
dock: 'bottom',
width: 360,
displayInfo: true,
store: 'GridStore'
}
]
}
]
});
me.callParent(arguments);
}
});
