GridPanel, GroupingStore and store.filter

[thatcoder]

How do you go about applying multiple filters to a store?

I've tried

store.filter('name', nameValue);
store.filter('status', statusValue);

If the name was the only item being filtered, things would be ok, but if it is a case where multiple filters were run on the store, only the last filter would be executed. Is there anyway to filter on the current snapShot of the store?

Just use filterBy, e.g.

store.filterBy(function(record, id) {
  return (record.get('name') == nameValue) && (record.get('status') == statusValue);
});

Hi all,
I have very basic question.
I can't make filters work.
I am using a grid and i like the grid to display only rows with 'install' string in the column 'type'.
I am using the data store in grid and this is the code for the data store:


function loadDataStore(){
var store = new Ext.data.Store({
url: 'url.do',
reader: new Ext.data.JsonReader({
root:'rows',
totalProperty: 'results',
id:'id'
}, [
'id',
{name: 'date', type: 'date', dateFormat: 'd/m/Y'},
'event',
'by',
'type',
'description',
'status'
])
});

store.load();
store.filter('type', 'Install');
return store;
}

Can anybody help me.
Thanks!

You forgot that loading is asynchronous.

Calling load() sends a request to the server, but the records won't be loaded until the response is received from the server.

Try:

store.load({
  callback: function(){
    store.filter('type', 'Install');
  }
});

Great that's working fine.
Thanks!

I don't understand. Can you rephrase the question?

Just use filterBy, e.g.

store.filterBy(function(record, id) {
  return (record.get('name') == nameValue) && (record.get('status') == statusValue);
});

I combine tehnique in here:
http://www.extjs.com/forum/showthread.php?t=66005 with code-snippet above...
to filter based on the generated-field (ajax)

But it doesn't work....

only for previously loaded store then it works.

Any clues?

I don't completely understand your problem...

But for the original problem:
Loading a store and then filtering it can be slow when a component (dataview, grid etc.) is attached, because all rows are rendered before they are filtered. That is why I requested persistent store filtering.
