Kendo DropDownList too slow while read dataSource

Question

I have kendo dropdown/multiSelect... Each of which is linked to a controller method which returns 37,000 items...

It takes a lot of time to show data...

So,I thought We DON'T HAVE TO return 37000 items to the dropdowns.

Is it possible to stop that buffering issue??

Answer 1

if you are using a multiSelect consider using the MinLength option :

Html.Kendo().ComboBoxFor(m => m.ObjectID)
                    //start autocompleting only after 3 char
                    .MinLength(3)

And as suggested in the first comment you could also take only the first n results in the controler action.
