weekHeader:true,
startOnMonday:false

}
dhx.ui(config);
//loading
dhx.extend($$(“mygrid”), dhx.ui.overlay);
dhx.extend($$(“myform”), dhx.ui.overlay); //render
$$(“mygrid”).render();
$$(“myform”).bind($$(“mygrid”));
//
$$(“myform”).attachEvent(“onValidationError”,function(id, data){
})
})
//
function save(){
if ($$(“myform”).validate()){
//show loading
$$(“myform”).showOverlay();
…
//hide loading
$$(“myform”).hideOverlay(); }
}

Logic which executed between showOverlay and hideOverlay commands are they sync or async ?

In case of sync logic - browser will not have time to render any element ( it will be busy with js code processing )

You can break sync logic as

function save(){ if ($$("myform").validate()){ //show loading $$("myform").showOverlay(); dhx.delay(function(){ ..... //hide loading $$("myform").hideOverlay(); }); } }
