Howto reset virtual scrolling on datasource.query()?

Hi there,

I'm looking for a way to "reset" virtual scrolling on sorting/filtering. E.g in the code below I'm resetting the sort, pageSize and page params to the default values. Note that especially page is set to 1. While the datasource is retrieving the correct dataset the scroll bar isn't reset.

$('#search').val('')

.focus()

.keyup(function (event) {

App.DS.sharableDataSource.query({

filter:{

field:"LastName",

operator:"startswith",

value:event.currentTarget.value

},

sort:App.DS.sharableDataSource.options.sort,

pageSize:App.DS.sharableDataSource.options.pageSize,

page:1

})

});

A live version that demonstrates this behavior can be found at http://openaccess.spirit.de/.

Without any filter applied scroll down a little and then either use the search box or the dropdown filter. The desired behavior would be that the dimension of the scroll bar would be newly calculated and the slider should move to the initial position whenever there's a request for page 1.

Thanks,

Rainer

Two DropDownList not functioning property in IE7 - list opens but never closes

I have a basic screen with two kendo ui dropdownlists and I'm testing with IE7. The second dropdownlist on the screen opens but then doesn't close after a selection is made. I created a sample page with only the two controls and I can duplicate the issue. The lists work fine in all other browsers. I also tested this with more than two kendo ui dropdownlists and the first one on the page always works and any subsequent lists have the same closing issue. I am a licensed user with a company in Philadelphia and I'm using the latest version of kendo v2012.1.322.

Here is my sample code:

How to load treeview nodes on-demand

Hi,

I want to do this:
For example, I have a treeview with one node "Root":
+ Root

Then when I expand this node, I will send a request to server and get child nodes of node "Root", and append to it.

But currently, if a node have no child nodes, the expand icon is not showed and the expand event is not fired, so I cannot do anythings further.

are there any ways that I can do that?

Thanks!
Thai

MVVM and binding events to Kendo UI Web Widgets

Hi, how can I bind some simple event like 'change' on MVVM to any of KendoUI widgets?
Example:

<input type="text" id="txtHours" class="kendoNumeric input-mini" data-bind="value: hours, change: hoursChange" />

And this is exception in web browser:
Uncaught Error: The change binding is not supported by the NumericTextBox widget

Binding events in similar matter for any other non-Kendo widget or controls works just fine.
Am I doing something wrong or binding just doesn't work for Kendo controls?

We’re developing a mobile application where we must use some sliders to update the value of one gauge. We were using your trial version and everything works great. However when we switch to your commercial version we got a huge bug: the slider doesn’t work, we cannot slide the slider from the web or any Mobile.
