Load data from Servlet to Grid in a Form

[ching29]

Hello,

I have a form with textfields and grids on it. I have populated data in the textfields from servlet by using the code below that is in my controller.


view.down('form').loadRecord(record);

Is there any way to populate data to the grids? I tried passing the data from controller to view and it properly worked by using the code below.

Controller:

var comboTopics = Ext.create('tdo.store.Topics',{
fields: ['topicCode'],
data : [
{"topicCode":"AP-018"},
{"topicCode":"FIN-004"},
{"topicCode":"GEN-013"}
]

});
var view = Ext.create('tdo.view.trngRecords.Edit',{id:Ext.id(),topics:comboTopics})


View:

initComponent: function() {
this.topics = this.topics;
console.log(this.topics);
this.callParent();
}


My problem is how can I make this store appear on my grid? and am I on the right track? Please help.

Code of my grid:


var comboTopics = Ext.create('Ext.data.Store', {
fields: ['topicCode'],
});


var topicGrid = Ext.create('Ext.grid.Panel', {
store: comboTopics,
columns: [{
header: 'Topic',
dataIndex: 'topicCode',
flex: 1,
allowBlank: false,
renderer: function(topicCode) {
console.log(topicCode);
var index = storeTopics.find('topicCode', topicCode);
console.log(storeTopics);
console.log(index);
return (index === -1) ? "" : storeTopics.getAt(index).get('topicDesc');
},
editor: {
xtype: 'combobox',
store: storeTopics,
queryMode: 'local',
displayField: 'topicDesc',
valueField: 'topicCode',
forceSelection:true
}
}]
});

Add a proxy to your store and configure it to read the data coming from your servlet. Then when you load the store it will send the request and display the data automatically.
