The horizontal data selection for line charts works great...for the applications I need to build, I also need the same sort of selection vertically. Please consider implementing this soon...i know others have inquired about this as well.

TypeError: Cannot read property 'get' of null↵    at makeWidgetInfo (<anonymous>:94:43)↵    at <anonymous>:507:33

I get this error during reloading the page. I assume this is in your extension.

Like we have datepicker and color picker, can we have a location picker control? The textbox will have lat and long values, which on clicking shows a map with a marker in a dropdown.

User can move the marker in the map and the lat long values will be correspondingly changed in the textbox.

An example is : http://logicify.github.io/jquery-locationpicker-plugin/#examples

I know there are a number of requests for this, and I'm in agreement with all of them. I wanted to post a couple of specific examples in order to make it clear what would save me (a developer using Kendo for production code) time in implementing widgets within our application.

1. Provide information about all aspects of any given topic. For example, I recently tried to understand how sorting works for Grid. (see  http://www.telerik.com/forums/where-is-the-documentation-on-performing-case-insensitive-sorting-for-grid). It seems like it would take a pretty minimal effort to include information in the docs for grid column-header sorting (http://docs.telerik.com/kendo-ui/api/javascript/ui/grid#configuration-sortable) that describe how to turn off case-insensitive sorting, as well as explain that the grid option does not sort data on initial load (for that you need to sort on the dataSource). It required a fair amount of searching, and a couple of days to come to this understanding, which could have completely been avoided by adding a paragraph or two to the docs examples I just mentioned. For any configuration option, or feature documentation, make it complete and describe it entirely.

2. Utilize hyper-linking more effectively within the docs. A while back, I wanted to understand how to fully utilize the numericTextBox widget, and the docs mentioned 'format' for numerics. Unfortunately, I don't know what 'format' means in the context of Kendo widgets. Eventually, I found this forum post: http://www.telerik.com/forums/where-is-documentation-on-format
As I pointed out in my comment in that post, there's simply no reason to require your users to search for what 'format' means, when with minimal effort on your part, a link can be added and I can simply click to that documentation and get the answer I need.

There's a ton of individual examples that fall into one of those two categories, and if those were fixed, about 60% of the documentation issues I encounter would be resolved. I appreciate the chance to express this, and thanks for your consideration.

I would like to implement something similar to what proposed here:
http://kendoui-feedback.telerik.com/forums/127393-telerik-kendo-ui-feedback/suggestions/6454228-separation-of-shapes-and-datasource-for-maps-in-da

Basically, it comes to binding shape properties to data: every time data changes, the filling of the shapes is changed accordingly.

Please, guys, this would be really good!

The only thing holding us back from investing in Kendo UI is the lack of a styleable scrollbar.  You have the most beautiful controls on the market, but they are marred by the mere built-in scrollbars (as rendered by the browser).

When do you plan to address the scrollbar?

Thank you.

Plotband functionality for RadHtmlCharts in UI for Asp.net AJAX definitely needs the ability to add tooltips and labels, otherwise the plotband is meaningless.

Kendo UI Gantt should have a resource view, presenting tasks by resource (so possibly, many tasks on the same line with automatic or manual arrangement) and possibility of multiselection of tasks

When asking for support from Telerik any code examples use the framework specified in the support ticket.  For example, not to give examples in php if you are using MVC etc.

I need to create this ...

        ''' <returns>Categories</returns>
        Public Overridable Function GetCategories(Optional categoryName As String = "", Optional pageIndex As Integer = 0, Optional pageSize As Integer = Integer.MaxValue, Optional showHidden As Boolean = False) As IPagedList(Of Category) Implements ICategoryService.GetCategories
            Dim query = _categoryRepository.SelectOne
            If Not showHidden Then
                query = query.Where(Function(c) c.Published)
            End If
            If Not [String].IsNullOrWhiteSpace(categoryName) Then
                query = query.Where(Function(c) c.Name.Contains(categoryName))

How do I get in VB.net

HI,
I still wonder why there is no text input autocomplete widget for Kendo Mobile.
I  like kendo MVVM to structure an APP. but i really need to use Autocomplete for my proyect (around 5 in different forms).

I guess i should go for ionic framework on AppBuilder (i really love the platform) if there is no way to implement autocomplete in a clear way.

Regards

Dear Telerik,

What are you waiting for to implement a exporting resources to KENDO UI DataViz?
You are losing market share because Highcharts and FusionCharts already have this possibility.

Please, let us know when it will be avaiable.

What I want to achieve is a dynamic Choropleth map of the World, whose data change according to a set of parameters.

It is my understanding that the maps widget in Kendo UI can display data in a Shape layer using GeoJSON files that contain both the definition of the shapes of the countries and the data itself (e.g. the population). From your GeoJSON demo it is clear how to change the colour of the countries using the Chroma.scale method.

But it also looks like I need the shape definitions to be duplicated over and over to show different data on the same map: 
let's say that I have about 400.000 possible combinations of the filters, it appears as if I'm going to need 400.000 GeoJSON files that contain both the shapes definitions and the the data and this means lots of network traffic.

My point is that, since the shapes of the countries do not change because the map is always the same, wouldn't it be useful to split the shape definition from the data itself?
In other words having a "shapeSource" property to which you link a GeoJSON that defines the shapes and the "dataSource" property bound to a JSON file that only has data: when the combination of filters changes I would only change the dataSource object.

My current solution is to have the "shapes definition only" file set in the dataSource property of the shape layer and then to use a Kendo.dataSource "data-only" object that I would use in the shapeCreated method to set the colours of the countries.

As a side note, the "data-only" Kendo.dataSource object will be shared between three widgets in the same page because the same data will be shown in a map, a chart and a grid.

Add rerender method to DropDownList, so that it could be dynamically refreshed after eintire select's HTML was changed.

i have a page with several select lists, and their options can be added/removed/disabled/enabled again based on a quite complex logic, which is easier to implement with DOM maniulation than with calling DataSource methods.

Would be nice to have such a possibility 

Be able to show an empty marker when the value is 0 for the sparkline like in this demo: http://dojo.telerik.com/@tsvetomir/ogiH/2

The demo use a hack to show the marker but it would good to have a real solution.

Your Kendo UI demos are useful, however they lack a basic overview to orientate new comers as to the specifics.  More importantly I would find it useful, and it would be more thorough, to provide examples in both Razor and JavaScript Syntaxes.

Add an Year view in addition to the Day, Week and Month views.

Currently, DataViz charts allow you to set a valueAxis's tick mark increments (increments of 100 would give you 0, 100, 200, 300, etc). I suggest a way to set a specific amount of ticks that your chart will always load, and the data will use divisions to fit the tick amount you set. Example: I want my chart to always display 5 ticks. I have two users, one who has a max number of 100 and the other has a max of 500. For User 1, the chart would set a max of 100 divided by the 5 ticks (so increments of 20). User 2 would get increments of 100 to fit the 5 ticks. 

Please provide "retina" support for Kendo Map.  At this point its kinda "table stakes" for a mapping component - let alone one that you need to pay for.
