I'm very new to the Kendo framework and I'm having an issue that I cannot pin down. 

The code that I pasted below works without issue when I run it in my development environment. 
However, when I deploy it to my production environment I do not get any results when there should be some.  I was able to use the Developer Tools in IE to finally track down why nothing was coming back.  It turned out to be due to a circular reference.  I cannot figure this out...I do not know what is causing this, how to fix it, or why it occurs in one environment but not the other.  Any help with this would be greatly appreciated.

Below is more details on the error I came across in the Developer Tools:
A circular reference was detected while serializing an object of type 'System.Data.Entity.DynamicProxies.Client_01B64F1E7422FE56835B4D229E8C469B1D4FDE4FCDE484EC36E547106D4A9766'.

I have a Kendo Grid where I filter based on an Enum. 
Let's say the Enum was:

Kendo Grid:

and




I would like for the Filter to show only Yes or No options. Is there a way to do this?

Hi there,

Inspired by the example on the demos site, I attempted to populate a calendar to show days when our system receives FTP uploads. Here is what I've got so far:
The code appears to be parsing okay, as I'm getting the date-empty class applied to each of my calendar elements. The JSON is arriving okay, and events is being populated, which leaves me with two scenarios that I can think of:

1. The async fetching of data is out of step with the calendar being built.
2. The $.inArray function is not behaving as intended with my new dataset.

I am trying to use Kendo Upload UI with Web API. I have the below signature in my web api controller, but somehow the POST is not working. It works fine with
MVC controller, but I need it to work with Web API. I also include the call made from the UI.

 public void AddFile(IEnumerable<HttpPostedFileBase> files, string id)
{
}  
            $("#files").kendoUpload({
                async: {
                    saveUrl: '/api/my/addfile',
                    autoUpload: true
                },
                upload: function (e) {
                    e.data = { id: $('#test').val() };
                }
            });

Which actions cause a redraw on a chart? 

chart.dataSource.read()
chart.refresh() 
chart.redraw()

I looked at the documentation and the API section provides no information on this, but it would be nice to know without having to resort to looking at the source code or having to post about it. 
Is there anywhere else where this would be documented? 

Thanks,
Jacques

I have a series of master details rows in a grid. In the detail of the master grid is a tab group. The detail grids are inside the individual tabs.

I am trying to format the display of an integer (4 digit year) inside the filter column. Removing the comma.

Here is the detail grid .csthml snippet.
The problem is that after the first detail row the formatting is no longer applied.

Also I am unable to move the format code to a .js file? I can't move it to any other .cshtml file either. Many of the detail grids have this column and having to put this filter format code into each of their .cshtml files is pretty "code smelly".

I am running the latest released build. 2013.2.918

Thanks,

Trav

Att: Kiril Nikolov,

Dunno where else to post this... so here goes:
The (multiple) posts from me about "setting the height of an editor" display erroneously using Safari, Chrome and Firefox on OSX.
Trying to access the thread does not result in the normal forum thread view, but rather an editable field containing some/all of the forum thread-html. 
It seems Kiril Nikolov was able to answer one of the posts that I am unable to get a proper view of - maybe Telerik staff acess forums through another interface?

We are converting an app from Telerik MVC to Kendo UI.  We have jQuery code on our grids to capture the current orderBy and filterBy parameters so we can pass them back to our controller.  The controller then creates an Excel download using those parameters.
However the orderBy and filterBy are now undefined in Kendo.  How do I retrieve those values?
    function onDataBound() {
        $('a.lnkDeal').each(function () {
            this.href = this.href.replace(/&/g, "%26");
        });
        var grid = $("#Deals").data('kendoGrid');
        // Get the export link as jQuery object       
        var $exportLink = $('#ExportToExcel');               
        // Get its 'href' attribute - the URL where it would navigate to       
        var href = $exportLink.attr('href');               
        // Update the 'orderBy' parameter with the grids' current sort state
        href = href.replace(/orderBy=([^&]*)/, 'orderBy=' + (grid.orderBy || '~'));
        // Update the 'filter' parameter with the grids' current filtering state       
        //href = href.replace(/filter=(.*)/, 'filter=' + (grid.filterBy || '~'));               
        // Update the 'href' attribute. Replace all ' with | to avoid security issue
        href = href.replace(/'/g, "|");
        $exportLink.attr('href', href);
    }

None of my views ever have scroll bars on them. Also, if I set overflow: auto on a div, it also will not have a scroll bar.

How do I allow scroll bars?

I've got a grid:
and I've tried all of these things to change the scrollable property:
Nothing works. How does one change whether a grid is scrollable on the fly?
