Is there a way for us to get access to the code that renders the virtual mobile device like on your demo site? I have a demo to present to our remote office and would love to show them our mobile app. simulated on a mobile device.

Thanks!

[Solved] Best way to handle filter as you type with large dataset?

Up until now I have been using your Silverlight tools /w a vb.net service as the backend. I have a couple dropdown menus which can have up to 100,000 values in them. I don't populate those lists or retrieve the data until the user starts to type. I do that by handling the onkeyDown event and quering the webservice, which returns 20 results at a time.

I just started playing with your kendo combobox, I am not that good at javascript but so far it has been going ok, I am impressed with the tools. I have my menus populating properly, from a REST web service, using mostly my same back end code, but at the moment I am not doing any filtering. I know that I can filter at the combobox level, but how do I filter at the webservice so it doesn't have to return all the data? Sorry if I missed this in the documentation, I am very new to this and appreceivate your assistance.

Cannot bind XML data to Grid using DataSource

I am having issues binding an XML dataset to a Kendo Grid using the Kendo DataSource object. My grid renders but has no rows.

Here is the page on which I am drawing the Grid and creating the DataSource (Default.aspx):

[Solved] Using a splitter on only selected div tags

I have some html that I have applied the splitter to.

<div class="frame">

<div class="left-nav"></div>

<div class="content"></div>

<div class="clear"></div>

</div>

My class left-nav has a set width of 200px and my content class doesn't have a set width.
clear just removes the floating.

Can the splitter be applied just to left-nav?

I have tried

$(".frame").kendoSplitter({

panes: [

{ collapsible: true,size:"200px",max:"200px"},

{},{}

]

});

But it applies a panel to the .content div.

Any suggestions?

Multiple use .k-window

HTML:
<div class="k-window">...</div>
<div class="k-window">...</div>
<div id="popup">...</div>

JS:
$("#popup").kendoWindow().data("kendoWindow").open();

I use the class k-window to decorate my own frames.

Window opens correctly.
But when I try to close (X) get (google chrome):
Uncaught TypeError: Cannot read property 'options' of undefined

If you do not use the class k-window everything works fine.

[Solved] Many Instances of a Window, one for each row in a grid

How would one create a new and unique Window for each row in a Kendo Grid? I only want one instance of the window, and each row comes from the database.

For example imagine a Kendo Grid that shows a hundred open jobs and their status. Each row has a link that says "Change status". Clicking that link will open a URL, with options. Upon closing, the grid is refreshed.

Thank you in advance!

Kendo dynamic injection rendering issue

Is there a method or function to re-render all Kendo controls displayed in the current screen? The issue I currently have is that when I inject controls dynamically without refreshing the page (using JQuery append() for example) Kendo will continue to render new and existing controls on-top of controls that have already been rendered.

Is there a simple solution to this common problem?
