Prevent initial call to load items

PDMDSUI

asked at 18 Feb 2014

you can't prevent the call, but you can control the data that is being returned (for example return an empty list when there's no parent value), why do you need this ?

because I have to do some calculations before the list could be filled. I can trigger the reload process again, but sometimes the initial reload process is slower then the second one and the wrong data is displayed.

you can set a parameter .Parameter("dontLoad", 1) so on the server you return an empty list initially, and after call the api with a parameter that will tell the server to ignore the first one. what calculations are you doing ? can't they be made at the server ?

Ok thx. How could I set this Parameter ("dontLoad") to 0?

@Html.Awe().AjaxDropdownFor(o => o.Meal).Parameter("dontload", 0) (http://aspnetawesome.com/learn/mvc/general)

OK, was question was wrong. How could I change this parameter after creation? Something like: $('#mealDropDown').setParameter("dontload", 0);?

using the api or by looking at the parent value; you're doing calculations how are you using the result of the calculation to influence the AjaxCheckboxList ?
