Hello,

I use the restful example, which I added the periodic refreshing of data.


var task = {
run: store.reload,
scope:store,
interval:2000
};

Ext.TaskMgr.start(task);

I would like to stop the periodic refresh of the grid during the seizure.

Because that's lose the input area.

Where could I put Ext.TaskMgr.stop(task); and Ext.TaskMgr.start(task); ?

// Application instance for showing user-feedback messages.
var App = new Ext.App({});

// Create a standard HttpProxy instance.
var proxy = new Ext.data.HttpProxy({
url: 'app.php/users'
});

// Typical JsonReader. Notice additional meta-data params for defining the core attributes of your json-response
var reader = new Ext.data.JsonReader({
totalProperty: 'total',
successProperty: 'success',
idProperty: 'id',
root: 'data'
}, [
{name: 'id'},
{name: 'email', allowBlank: false},
{name: 'first', allowBlank: false},
{name: 'last', allowBlank: false}
]);

// The new DataWriter component.
var writer = new Ext.data.JsonWriter();

// Typical Store collecting the Proxy, Reader and Writer together.
var store = new Ext.data.Store({
id: 'user',
restful: true, // <-- This Store is RESTful
proxy: proxy,
reader: reader,
writer: writer, // <-- plug a DataWriter into the store just as you would a Reader
listeners: {
write : function(store, action, result, response, rs) {
App.setAlert(response.success, response.message);
store.load(); // Ajouté pour forcer le rafraichissement - Add to force the refresh of the data - LP
}
}
});

// Let's pretend we rendered our grid-columns with meta-data from our ORM framework.
var userColumns = [
{header: "ID", width: 40, sortable: true, dataIndex: 'id'},
{header: "Email", width: 100, sortable: true, dataIndex: 'email', editor: new Ext.form.TextField({})},
{header: "First", width: 50, sortable: true, dataIndex: 'first', editor: new Ext.form.TextField({})},
{header: "Last", width: 50, sortable: true, dataIndex: 'last', editor: new Ext.form.TextField({})}
];

// load the store immeditately
store.load();

Ext.onReady(function() {
Ext.QuickTips.init();

// use RowEditor for editing
var editor = new Ext.ux.grid.RowEditor({
saveText: 'Update'
});

// Create a typical GridPanel with RowEditor plugin
var userGrid = new Ext.grid.GridPanel({
renderTo: 'user-grid',
iconCls: 'icon-grid',
frame: true,
title: 'Users',
autoScroll: true,
height: 300,
store: store,
plugins: [editor],
columns : userColumns,
tbar: [{
text: 'Add',
iconCls: 'silk-add',
handler: onAdd
}, '-', {
text: 'Delete',
iconCls: 'silk-delete',
handler: onDelete
}, '-'],
viewConfig: {
forceFit: true
}
});

/**
* onAdd
*/
function onAdd(btn, ev) {

var u = new userGrid.store.recordType({
first : '',
last: '',
email : ''
});
editor.stopEditing();
userGrid.store.insert(0, u);
editor.startEditing(0);
}
/**
* onDelete
*/
function onDelete() {
var rec = userGrid.getSelectionModel().getSelected();
if (!rec) {
return false;
}
userGrid.store.remove(rec);
}

var task = {
run: store.reload,
scope:store,
interval:2000
};

Ext.TaskMgr.start(task);

//Ext.TaskMgr.stop(task);

});

I have found a solution :


// use RowEditor for editing
var editor = new Ext.ux.grid.RowEditor({
saveText: 'Update',
listeners:{
beforeedit: function () {
Ext.TaskMgr.stop(task);
},
afteredit: function () {
Ext.TaskMgr.start(task);
} }
});

That's work fine, when I edit the fields, refresh stop, when click on Update button, refresh start.

But when I click on the Cancel button refresh don't start !

I you have an idea ?
