how to make dhtmlxobjct's loadxml Synchronization?

for the dhtmlxgrid ,the dhtmlxcombo, the loadxml is Asynchronous default. but there is any way to make them Synchronization?



Previous,I use erro way to do it, I modify dhtmlxcommon.js , but it will effect all dhtmlobject.



is there a perfect way?

There is no way to achieve such effect by API calls.
It possible to modify code of dhtmlxcommon.js ( it will affect all components ) or just a code of dhtmlxgrid.js ( in such case it will affect only grid )
dhtmlxgrid.js , line 97
this.xmlLoader=new dtmlXMLLoaderObject(this.doLoadDetails, this, true, this.no_cashe);
can be changed as
this.xmlLoader=new dtmlXMLLoaderObject(this.doLoadDetails, this, false, this.no_cashe);

thanks a lot
