Comments on: Keeping modified records of EditorGridPanel while paging

One note… In 3.3.1 as Corey stated… Duplicates appear in the modified array. The link to the store is being broken simply using the code above. It is very close, but not quite there. The complete code to accomplish this without losing the link is below…

var modified = store.getModifiedRecords();
this.modified = [];
for (var x = 0; x < modified.length; x++)
{
var r = store.getById(modified[x].id);

if (r)
{
var changes = modified[x].getChanges();
for (p in changes)
{
if (changes.hasOwnProperty(p))
{ r.set( p, changes[p] ); }
}
}
else
{ this.modified.push(modified[x]); }
}

I don\\\’t know why, but I was getting duplicate entries in the modified collection after I page out and page back. Mind you, I\\\’m doing server-side paging.

So after getting the changes on this line:

var changes = modified[i].getChanges();

Remove the record like so:

store.modified.splice(i, 1);

And you\\\’re sweet! It gets added again when you call set() on the record anyway.

Despite the fact I\\\’d imagine that modified collection is meant to be private/protected, it works.

Thank you for this! It is exactly what I was looking for.

You can modify this line :

var r = store.getById(modified[i].id);

by your own adaptation if you are an unique colum id :

var r = store.getAt(store.find(\’name\’, modified[i].data.name)) ;

Saki, modified[i].id, is changed after each loading (firebug).

See RecordForm example, I’ve copied the code from there. I hope that I haven’t made a mistake…

Am using below code but the data is not retaining while moving to another page

var dsnew = new Ext.data.Store({
proxy: new Ext.data.PagingMemoryProxy(dsgrid.reader.arrayData),
remoteSort: true,
pruneModifiedRecords :false,
reader: new Ext.data.ArrayReader({},
[
{name: 'IsSlected',type: 'bool'},
{name: 'RecNo',type: 'int'},

]),
listeners:{
update:{scope:this, fn:function(store) {
var modified = store.getModifiedRecords();
for(var i = 0; i < modified.length; i++) {
var r = store.getById(modified[i].id);
if(r) {
var changes = modified[i].getChanges();
for(p in changes) {
if(changes.hasOwnProperty(p)) {
r.set(p, changes[p]);

dsnew.refresh;
}
} // eo changes loop
}
} // eo modified loop
}} // eo load listener
} // eo listeners
});
