Get Count/Length/Size of Kendo UI DropDownList

Question

I am tring to get count of Kendo UI DropDownList but I am not getting right value. By taking count of Kendo UI, I want to remove last item from Kendo DropDownList. I tried following but not working:

1.

var dropDown = $("#RoleDrp").data("kendoDropDownList");
var len = dropDown.value().length+1;
var itemToRemove = dropDown.dataSource.at(len);
dropDown.dataSource.remove(itemToRemove);
dropDown.select(0);

I am getting length as 6 but I have total 13 items in DropDownList.

2.

var len = dropDown.length;

I am getting undefined.

try this :-var dropDown = $("#RoleDrp").data("kendoDropDownList"); var lengthOfDropDown=dropDown.dataSource._data.length; – Schell

you shouldn't access _ variables directly in kendo controls unless you're in the console debugger. Use the getter. You don't know if you have access to it or not as it could be scoped. – Armpit
