Event that fires once the store has data - extjs

Question

I have a proxy store that fills through two different ways - either via loadData, or via load.
I have certain actions that should take place once the store is filled; namely, a certain record should be searched and selected:
preselectByName:function(name, groupName) {
var store = this;
if(store.preselected) return;
store.preselected = true;
store.on('load',function() {
store.selectByName(name, groupName);
store.preselected = false;
},store,{single:true});
}
called like this:
if(store.isLoaded) store.selectByName(name, groupName);
else store.preselectByName(name, groupName);
This code works fine if the store fills via load, but not via loadData.
Is there another event that is fired from both load and loadRecord?
How else would I implement a listener that fires on any of the two events, whichever comes first?

Answer 1

datachanged (http://docs.sencha.com/extjs/6.2.1/classic/Ext.data.Store.html#event-datachanged)
is an event, that fires from both load and loadRecord, but be careful, it fires from any change that made to the dataset.
Besides: I usually use this to find the event that I need in ExtJs:
Ext.util.Observable.capture(myObj, function(evname) {console.log(evname, arguments);})
It captures all ExtJs events, fired by the myObj component and logs it to the console.
Or you could create a custom event, which you fire manually on load and after loadData, like:
store.on("load",function(){store.fireEvent("myload")})
and
store.loadData(...)
store.fireEvent("myload")
then
store.on("myload",function(){...})

The load event is specifically for reading data from a remote data source. The store can be extended to introduce an event that satisfies your requirements.
/*
#event loadrecords Fires whenever records a loaded into the store.
#param {Ext.data.Model[]} records An array of records
*/
Ext.define('MyApp.data.Store', {
extend: 'Ext.data.Store',
load: function() {
this.callParent(arguments);
this.fireLoadRecords();
return this;
},
fireLoadRecords: function() {
this.fireEvent('loadrecords', this.getRange());
},
loadRecords: function(records, options) {
this.callParent(arguments);
this.fireLoadRecords();
}
});
