Dear all,
I want to add button in toolbar of Grid panel on right side. But it is not working. Please help me. Below is my code.

tbar:[{
type:'button',
text: 'Import Task',
align: 'right',
icon:'images/drop-add.gif',
handler : function() {
win1 = Ext.widget('window', {
title: 'Import Task',
closeAction: 'hide',
width: 550,
height: 450,
minHeight: 400,
layout: 'fit',
resizable: true,
modal: true,
items: form
});
win1.show();
Ext.getCmp('action').disable();
}

}]
