I'm attempting to use the Kendo UI DataSourceResult with my Kendo UI Grid using the code found here.
I'm not using ASP.NET MVC, but rather VB.NET with ASP.NET Web Forms and Web API on the backend. I understand how the DataSourceResult object works, however I'm having trouble figuring out the lines of code at lines 19-21. Here is the code in C#:
DataSourceRequest request = JsonConvert.DeserializeObject<DataSourceRequest>(// The request is in the format GET api/products?{take:10,skip:0} and ParseQueryString treats it as a key without valuerequestMessage.RequestUri.ParseQueryString().GetKey(0));and the code equivalent in VB.NET:
' The request is in the format GET api/products?{take:10,skip:0} and ParseQueryString treats it as a key without valueDim request As DataSourceRequest = JsonConvert.DeserializeObject(Of DataSourceRequest)(requestMessage.RequestUri.ParseQueryString().GetKey(0))Whenever I execute the code I get a System.ArgumentOutOfRangeException. Debugging the code the requestMessage.RequestUri.ParseQueryString().GetKey(0) returns "take" which is what I'd expect, as that's the key of the first parameter. Using Fiddle I can see that the Grid sends the RequestUri of "http://localhost:53786/api/object/4?take=20&skip=0&page=1&pageSize=20". What do I need to do to get the code working correctly with my Grid and API?

When using the Office 365 theme with AutoComplete (the same goes for MultiSelect) appears to be 'broken'. As a matter of fact it actually the navigation itself does work, but the currently selected item does not get highlighted when navigating throught the item popup.

When scrolling the grid horizontally with the arrow on the sides, the movement is very slow. On longer column or more rows, it slows down even more. Whereas While moving by dragging the slider with the mouse, it moves fine.
Kindly provide me with a solution to fix this horizontal scroll issue.

I'm trying to streamline the template information on my barchart. It is just not displaying the information I would like it to relay to the user in a streamline fashion. I have a demo at http://dojo.telerik.com/@dhighfield/AFEbu/2. I'm trying to have it display something similar to the included png files. I do not want the template to display items that have zero values associated with it. I also am trying to remove that top Code information and replace it with the Code Description. I've tried series and category and other implementations and this is probably the closest I ever got to what I am looking for. Can this be accomplished?
As always thank you for your time.

I am trying to filter on a value in a child array of an object using server side filtering
I have an object like:
On a grid I generate a custom filter template which allows a user to filter by Accounts (e.g a dropdown list of accounts).
The datasourcerequest object on the server is populated with a filter. I want to be able to intercept the filter and change the filter from an equals
to a contains
I've done the following
private DataSourceRequest InterceptRequest(DataSourceRequest request)
{
for (int idx = 0; idx < request.Filters; idx++)
{
var flt = filterList[idx] as FilterDescriptor;
if (flt != null && flt.Member.ToString().Equals("accountIdList"))
{
flt.Operator = FilterOperator.Contains;
flt.Value = 1; //Hardcode as an example
}
}
}
However when I call ToDataSourceResult I get an error stating an invalid cast from Int32 to IEnumerable<Int32>
I want to get a list of all persons who have an Account Id of 1. How can I achieve this?

Sample: http://demos.telerik.com/kendo-ui/m/index#mobile-view/zoomable
If you view the above link in IE11 maximized at a high resolution (such as 1080p or 4K), the touch-based zooming and scrolling will not work like other browsers. Is there a workaround for this, or is this not supported in an older browser like IE11?
