Hello!
I did a quick search but only saw one or two things around this.

The code block at the bottom of this post renders a Kendo Chart with 2 series, each containing 30 data points, and tracks the time taken (in milliseconds) to complete the call to the kendoChart function.

We have a VM running IE7, and another running IE8, for testing purposes. index.html (the code block) resides on my local web server, I remote desktop to a Windows XP VM (on a separate server) which is running either a real copy of IE7, or IE8, and then I browse back to that page on my local web server.

Note that the time shown in milliseconds at the bottom of the page is only tracking the call to kendoChart.

With this page, I've seen times as bad as 10 seconds in true IE7 (not using IE9 browser mode).
IE8 achieves times around 500ms, this is still approximately 5x worse than Firefox or Chrome achieve with great consistency.

IE7 VM, min: ~3000ms, max: ~10000ms, quite inconsistent.
IE8 VM, between ~500 and 600ms consistently
Firefox and Chrome on the VMs, between ~100 and 200ms.
Local machine IE7 & 8, using IE9's Browser Mode setting, ~100 to 150ms.

Are the any recommendations or "best practices" that I've not been able to dig up so far, with regards to Kendo Chart and older IE versions?
Is there anything I can do to improve the render time in IE7 or IE8.

I have an ASP.Net MVC Kendo UI combobox that is databound to a table with 1000's of records. I've set the MinLength property to 5 so I only return relevant results. The problem is, the user might need to change the text value all together. Is there a way to tell the control to refresh?

Here's the code for the control...

@(Html.Kendo().ComboBoxFor(x => x.Product)
                    .Name("Product")
                    .DataTextField("Name") // Display value
                    .DataValueField("Id") //Return value
                    .MinLength(5)
                    .AutoBind(false)
                    .Suggest(true)
                    .Filter(FilterType.Contains)
                    .DataSource(source =>
                    {
                        source.Read(read =>
                        {
                            read.Action("Products", "Home").Data("onGetProducts");
                        });
                    })
                )

This is also a post on stackoverflow.

When I edit a bunch of fields in a row, I click update and it sends the data to my php server. The php server sends back some json data and I want the same row to update.

For example:

I update a row and it has some fields in it like projectscore, adjustment and weight. The server saves the data and sends back the project total so it can be properly updated in the table. right now this is the json postback
{"id":"1","ptotal":75}

id is the id of the row (specified in the table, this is working), and ptotal is the column name of the column I need updated

How do I update the column in the table from the response from the server after an update or a create?

This is a server side php, client side kendo system (the table is a nested table in a hierarchy setup)

I realize this isn't part of the documentation, and I haven't glanced through the sourcecode yet to see if there is anything undocumented to allow this... 

Is it possible, or are there plans to make possible, the ability to use the SPA additions to the framework without url fragments?  Namely, a switch for the SPA framework that is able to use a combination of Pushstate, querystrings, and well-defined pages to create an ajax-driven pseudo-SPA similar to what we see in the KendoUI demo website that uses normal page-loads for those using older browsers?

I have assigned a class to the column-header of a particular column.  I use the following CSS to set the style:

              th.foo {background-color: #339933  !important;
                           color: white !important}

This works correctly in IE9 and Safari, but only the font-color changes in Chrome; the background color does not change.  So I believe the selector is correct.  Does anyone know what is causing the Chrome issue?


    

I've been heavily relying on the following: http://code.google.com/p/jquery-jsonp/

Can the Kendo DS do this as well by any chance?  The performance gained from the cache is AMAZING.

Want to make a mobile website a little snazzier for a potential client. The page contains only a kendoGrid, and if in Portrait mode, only 1 column shows; in Landscape mode, all columns are shown.

I'd like to have the showColumn/hideColumn functions to animate the column widths instead of using the show() and hide() jQuery functions.

Are there plans or a workaround to make this happen?

Hi,
   I have a  grid with footer showing the aggregates of the columns, I need to change the backgound color of the cells in the footer (complete row), I tried using the .k-footer-template class, but it is not working.........

Hi,

I'm opening Kendo Window using: 

• var window = $("#window").clone(); 

After opening the window I can't find a way to close it from the window using: 

•  window.parent.$("#window").data("kendoWindow").close();

If I open the window without .clone() this works fine but then the window content does not refresh always. With .clone() I get following error: 

• TypeError: 'undefined' is not an object (evaluating 'window.parent.$("#closeThisWindow").data("kendoWindow").close')

I  guess this is because the reference to the cloned object is unknow. I would like to know how to refer to this .clone() window from inside this opened window.

 I would like to implement the Tree view nodes in drop down as shown in attached file
the same can be achieved using telerik and i would like to know how in kendo ui MVC
