Ext.ux.LiveGrid

[NicoP]

Hi,

I am testing the last release of the live grid. I notice that the variable "bufferedSelections" has disappear. So when I select several rows I cannot use this king of function which works with older live grid release :

var rowList = Ext.encode(myGrid.getSelectionModel().bufferedSelections);

Is there a another way to retrieve multiple row selection ?

otherwise I will parse myGrid.getSelectionModel().getSelections() but with this functions we cannot retrieve row num...

Thanks

You should be able to use editing by simply changing the Ext.ux.grid.livegrid.GridPanel with the Ext.ux.grid.livegrid.EditorGridPanel-class.

That was the first thing I've intuitively tested. It works very well! I just thought maybe there is an extra example that shows some things that should be respected but if there are none... it's also great

Well, I've brought this feature into the 0.3 branch since so many people requested it and used hacks to use their own version of an EditorGrid.
You should consider that storing modified records and syncing changes on scroll afterwards does not fully work yet, as modified records get replaced upon buffering by the data that comes from the server. So by now, you should store all the changes you've made right after your edit field loses focus, i.e. send the request out to the server to store the changes permanently.

Well, that's really importan to know. I'll test it. I'm currently not sure how I'll use it, but just for information it would be nice to know wheter fully support is sheduled in 0.3 oder any other version?

I won't bring any new features into the 0.3, so I guess you'd have to wait for the 0.4 release

All right . 0.4 is not so far. Don't hurry up. I'm sure there is enough to do in 0.3 and other projects .

Hi, having this error and can't find a way to solve it.

Code follows:

bdApp.appBrowserGrid = Ext.extend(Ext.ux.grid.livegrid.GridPanel, {
	initComponent : function(){
		// RECORD
		var readerRecord = Ext.data.Record.create([
			{name: 'rowId'},
			{name: 'appName'}, 
			{name: 'description'}
			]);
		
		// READER
		var gridReader = new Ext.ux.grid.livegrid.JsonReader({
			root            	: 'resultSet',
   		totalProperty   	: 'totalCount',
   		id              	: 'rowId'
   		}, readerRecord);

		this.region = 'center';
		this.anchor = '100% 100%';
		this.autoExpandColumn = 'description';
		
		// STORE
		this.store = new Ext.ux.grid.livegrid.Store({
			autoLoad   	: false,
			bufferSize 	: 100,
			reader		: gridReader,
			url			: 'php/getAppBrowserStore.php'
		});
		
		// SELECTION MODEL
		this.selModel = new Ext.ux.grid.livegrid.RowSelectionModel();
	
  		this.view = new Ext.ux.grid.livegrid.GridView({
			nearLimit      : 100,
	      loadMask : {msg : 'Cargando datos...'},
			autoFill: true,
			columnsText: 'Columnas',
			sortAscText: 'Ordenar ascendente',
			sortDescText: 'Ordenar descendente',
			forceFit: true
  		});
  	
  		//this.tbar = new appBrowserTBar();
		this.bbar = new Ext.ux.grid.livegrid.Toolbar({
   		view        : this.view,
      	displayInfo : true,
			displayMsg	: 'Mostrando {0} - {1} de {2} registros',
			emptyMsg 	: 'No hay datos para mostrar',
			refreshText : 'Releer datos', 
		});
		this.on('render', function(){this.store.load();});
		bdApp.appBrowserGrid.superclass.initComponent.call(this);
	}
});

bdApp.appBrowser = Ext.extend(Ext.Panel, {
	initComponent: function(){
		var browserGrid = new bdApp.appBrowserGrid({
			loadMask: 'Cargando datos...'
		});
				
		Ext.apply(this, {
			layout: 'border',
			border: true,
			frame: true,
			anchor: '100% 100%',
			autoExpandColumn: 'desc',
			items: [browserGrid]
		});
		bdApp.appBrowser.superclass.initComponent.apply(this, arguments);		
	} 
});
Ext.reg('appBrowser', bdApp.appBrowser);

Thank you in advance.

I think that, the "nearLimits" value must be lower than the "bufferSize" otherwise the grid will be always reloaded each time you scroll lines.

Mmm, the error is more of "Can't find the fields for your store". Which is strange since is defined.

Here's my json response:

{'version': 0, 'totalCount': 2, 'resultSet':[{"rowId":"1","appName":"BDFE","description":"BDMex Consulting S.A. de C.V. - Factura Electr\u00f3nica"},{"rowId":"2","appName":"SYSTEM","description":"Aplicaci\u00f3n gen\u00e9rica."}]}
