kendo.bind() binds the element and all child elements to the viewModel by calling bindElement.
bindElement calls first unbindElement so that works fine if you call kendo.bind() multiple times, e.g. when you want to bind another model to your markup.
But bindElement also creates widgets if an element has a data-role attribute.
unbindElement on the otherhand does not destroy the element. So bindElement will again create the widget when you call kendo.bind() a second time. Should there not be a check if the widget is already created?
So
1) In the bindElement (or somewhere deeper) should bet checked if the widget is already created and if so do not create again
2) Add a parameter to kendo.unbind() to optionally destroy the widgets.
a) This would be a perfect oppertunity to destroy dom elements like the popup of a dropdownlist ( see http://www.kendoui.com/forums/ui/dropdownlist/how-to-clean-up-dropdownlist-lists.aspx#1991068)
b) By making it optional you have the oppertinity to keep all your widgets and just only bind a new (view)model to your markup.

When you want to click on the scrollbar to scroll, the popup is closed.
You can reproduce it in your own demos:
http://demos.kendoui.com/beta/web/dropdownlist/remotedatasource.html
In the current version it is working fine:

I have this HTML:
<select data-role="dropdownlist", data-bind="value: xxx", data-text-field="field1", data-value-field="field2", data-source='{"transport":{"read":"my-url"}}' />
Then I bind this template.
But the data-source is not used.
Found an issue in the function kendo.initWidget.
Inside that function there is the code:
dataSource does here indeed have the transport object I defined in the attributes. But window[dataSource] is undefined.
Seems to me that this line of code must be:
When I change it this way, the dropdownlist works!
So not sure if this is a bug or that I am doing something wrong.

Hi team,
I attended the webinar yesterday and today I started testing things out.
I followed all the steps and created tabstrip.
With 3 html pages.
Clicking on tabstrips pointing to html page is not working. Link is getting created like account.html/#account.html and it is not working.
R u going to load the demo you shown somewhere so that we can match code and see what we are doing wrong.

Hi,
I used the this article (http://www.adobe.com/devnet/html5/articles/getting-started-with-phonegap-in-eclipse-for-android.html) to
build my Kendo Mobile Application.
The Applications is working Ok as a Web Application but the Phonegap version has a problem. It works ok but when I turn the tablet to landscape the application crashes.
Is there any known issue about this ???
Thanks in advance

I have a JSON object that is returned from the WS which will have a sample of below:
{
"MenuID": 5,
"MenuVersion": 1,
"MenuName": "Lunch Menu",
"MenuItems": [
{
"Name": "TUSCANI MEDITERRANEAN CON POLLO",
"Description": "Pasta",
"PKID": 2,
"ParentID": 1,
"Ingredients": [
{
"PKID": 123,
"IngName": "Cheese",
"Included": true,
"ExtraPrice": 0},
{
"PKID": 124,
"IngName": "Sausage",
"Included": false,
"ExtraPrice": 0.99}
],
"ItemPricing": [
{
"PKID": 456,
"SizeName": "Large",
"SizePrice": 12.99},
{
"PKID": 678,
"SizeName": "Small",
"SizePrice": 14.99}
]}
]
}​
Are there any examples on how to work with complex objects like these. (Loop through the Menu items in this example and being able to display required info.) . I need to dynamically display the prices or ingredients to the user based on what is selected. I will be having more than one Menu Item to work with.
Thanks,
Chandu

And disappear from original position?
And then move it inside the target from one spot to another?

In the above link, the "Drag" and "Drag Axis" examples use a lowercase "kendo" when I think they should be using a capitalized "Kendo".
