[Solved] Ipad issue: cascading dropdown is blank

[Samuel]

Hello, 

Infos:

I'm working with kendo 2014.1.318 in an asp.net MVC application : I use the wrappers.

I have an issue with the cascading dropdown on Ipad (IOS 8.1 safari)
The issue is not reproducible on windows browsers, I tried ie9, chrome, firefox and safari for windows : no problem

So, here is the problem:

I have a first dropdown containing a list of brands.
I have a second dropdown with a list of models

First I select a brand 
My dropdown "models" is populated => ok

Then I select a brand with a few models

My dropdown "models" is populated but the popup is not painted: it's all white (see attached screenshot)

But if I touch the popup a few time: the items appears

If I select a brand with a lot of models : no problem

So I think this issue only appears when the number of items in the "models" dropdown is not big enough to activate the scroll in the popup


Has anyone experienced this issue?

Do you have any ideas how to resolve this ?

The issue was caused by the scrollviewer



The solution was to reset it

var modelescombobox = $("#myddl").data("kendoDropDownList");
var scroller = modelescombobox.list.data("kendoMobileScroller");
if(scroller)
{
scroller.reset();
}
