Is it possible to post data back to a controller using a FormCollection object? I would like a user to be able to open a kendo window and select, by way of a checkbox, multiple entries. Then close the window, change data on the parent page and then submit the form (note: the kendo window div exists inside the form). I can get the kendo window to open and display all the data via a listview but I'm not sure how to get the checkbox values (the only piece of the kendo window the user can edit) back to my controller. I suspect kendo might be destroying all the data selected when the window is closed (note: I do not call the destroy command on the window) so I figured I could always create a bunch of hidden fields on the parent page and update them as the user checks off the check boxes but I was trying to avoid that.

I can always change my controller to a DataSource Object but I'd like to avoid rewriting code. The controller called is 

Kendo Devs,

I am looking to display one line and one bar series upon the same set of axes, however each will pull from a different API URL, therefore does anyone know how to combine two DataSources into one chart?

Below is my code so far; the bar series (dataseries1) successfully pulls data from the API  and plots it as a bar chart on the axes; I have manually extracted Y values for the line series and passed them in as a .data array as you will see in the code; in an ideal world, i would like to be able to add 'dataSource: dataseries1,'  into the  line series. The commented out data is what the API returns.



Thanks in advance,
Jamie

Can we have a simple example with zoom capabilities of the new 2012.3 features in the chart.
Thanks.

Hi

I currently have the following but I would like to be able to specify the ranges dynamically using sliders. Can anyone tell me how to implement this?

Note - there will always be four ranges, its just where these start and stop is where I want to regulate.

I have a simple set of charts that are in Windows working great under 2013.2. I upgraded to 2013.3 and now the Windows appears and the chart's X and Y axis, legend and labels on the axis appear, but the data is not rendered, the charts are empty. See attached image. It was working fine in 2013.2 but after I ran the 2013.3 update it stopped working. In the html output, the data is there serialized in json, it's just the lines and bars of the chart no longer appear.

I have experimented by removing as much of the settings for a chart and window as I can, but still, no data appears.


Here's the data Kendo's MVC wrapper writes to HTML:

Hello,

On a  form submission I am dynamically creating a chart in javascript, using remote datasource (json/GET). When user clicks a "Close" button, I  destroy the chart, and empty the DOM element. When a user submits the form again with different data, I  create the chart again and load it with the new data.

The problem is this: after I  destroyed the chart, when  the form is submitted and I create a chart again - it instantly animates with the previous search data, as if the series have been cached! (Datasource ajax request is shown as Pending at this time on the Network tab in Chrome) Two seconds later, when the ajax request is complete, the chart is refreshed with the new set of data.

Here is my code. Chart creation function:
Chart destroy function:
HTML:
I am using JQuery 1.9.1 and KendoUI v2013.1.514, in Chrome.

Could you please advise? Thankyou, Kate.

In MVC, can the DropDownList have its width changed?

I've seen posts on how to do it on the client, but would rather have it at the MVC level.
