DataStore Prototype

I do not see a dataStore forum, so I hope it is ok to ask here.

What is the proper syntax to create a data store prototype?

something like:

dhtmlXDataStore.prototype.xyz = function() {	
  // do something
}

This syntax does is working…must be close?

The syntax seems to be ok as an error is not thrown when the page is loaded.

I do get an error when calling:

myDs = new dhtmlXDataStore();
myDs.xyz();

Uncaught TypeError: Object # has no method ‘xyz’

dhtmlXDataStore is an alias, so to add something to prototype, you need to use

dhx.DataCollection.prototype.xyz = function(){}

Great thank you. I have my own .post() prototype for forms and dataStores.
