    Looks are not enough... Performance please !!!

    Besides reasonable funcitonality and good html5 looks we really need to start hinking about how to bring this to a new level of performance. Data's getting bigger and bigger but the charting tool hasnt up'ed their level in handleing that data. Please review and increase the cap of how many point a simple bar chart can handle...Example?
    try plotting 4k points ( x axis being 0 or 1 and y axis jsut a count from 1 - 4k) using a bar chart. One of them might be reasonable but what if you have…

    • Scheduler No Data Template

      I would like to define a template or a message or something such that when there's no events the scheduler doesn't just look like a smushed collection of buttons, or having to set a min-height on the event zone or some other hack.

        • DataSource's "read", "fetch", and "sync" methods should return a deferred

          There has been many scenarios where I've needed to know when a DataSource finishes a "read" or "sync" operation.

          I know there's the global "sync" event that I can bind to, but a lot of the time I only care about the result of one specific sync call. I can use the "one" method to only listen to it once, but this complicates things when I also care about errors. Since I need to register callbacks for both the "sync" and "error" events, and then unregister either one or the other, depending on which event fired.

          It's even harder hooking…

            • Telerik Asp.net Web Control and Features

              I think that many great ideas are already presents into the Telerik Asp.net Web Suite and that many of them MUST be "imported" (as soon as possible) into Kendo UI. Controls like SocialShare, File Exporer, Image Editor, Lightbox etc are some "must have" that will be fantastic to see into Kendo UI. Or for example having many of the Telerik Ajax Editor features into Kendo UI editors can be take into account. I suppose that trying to unify the "Telerik Web Controls World" can help future implementation (sharing things like XAML and Silverlight also if more difficult but maybe its…

              • beforeEdit event on Grid

                Currently, if a field is editable based on other field (e.g. Locked) a check should be performed in "edit" event handler, and inside here call grid.closeCell(). But this causes the cell focus to be lost (when using navigatable=true in batch editing mode).

                So a beforeEdit would allow the user to set some custom logic if needed.

                • Add official support for range and prefetch methods on DataSource

                  There are several undocumented methods on the data source which provide some really nice functionality. The DataSource is able to store multiple 'pages' of data in an internal collections of ranges that can be accessed and populated by the range() and prefetch() methods. It looks like this is used mostly to support virtual grid scrolling, but I have found it very useful for other applications where a data source uses server operations. This is a really great feature and I'd like to see it officially supported in the future!

                  • Selection on X/Y graphs

                    By design chart selection is supported only for categorical charts (bar, column etc.) but not for XY-charts (scatter, scatterline etc.).

                    I'd like a similar UI for scatter charts to enable you to select data from the chart especially when the x axis is a time line.

                      I think it would be more helpful if the Kendo UI Documentation is structured similarly to other Telerik Product Documentations where each control (widget) provides a complete overview, visual structure, getting started, and a how-to section (which I'm guessing is a compiled list of frequently asked scenarios). I'm struggling/spending too much time having to research how to do (what should be) the simplest things with these widgets. It seems that' I'm having to revert to the Demo's and online threads more than the documentation.. that' can't be good!

                          • Create a standard way to handle errors in the Upload control

                            When using inline/batch/popup editing for grids, there is a standard way to handle server-side validation errors (from the ModelState) on the client : http://blogs.telerik.com/kendoui/posts/13-08-29/handling-server-side-validation-errors-in-your-kendo-ui-grid

                            When using the Upload control, the proposed solution is to use XMLHttpRequest.status and XMLHttpRequest.statusText, which is currently not very reliable, and complicated to handle. It's also a non-standard way in ASP.Net MVC, and breaks existing best-practices for error handling.

                            There should be a way to handle ModelState errors on upload.

                                  • Setting aggregate(..) on datasource should send unique action to change handler

                                    We have a MVVM object with a change handler.

                                    One of the public properties on this MVVM object is a datasource.

                                    This datasource has some default aggregate configuration, but some aggregate configuration is added later. (see first screenshot)

                                    However, when the dataSource.aggregate(..) method is called the MVVM's change handler fires (see second screenshot). This is ok, but there is nothing to distinguish that the change handler has been fired ONLY because the aggregate configuration has changed. When run some code when the datasource is defined or loaded, but we don't want to run the same code when the aggregates changes.

                                    • Dataviz chart click events expose e.event.originalEvent

                                      As per support ticket 806897

                                      Telerik: "By design both seriesClick and plotAreaClick events of Kendo UI Chart don't contain information about the clicked button or mouse coordinates. We will appreciate it if you submit this idea as a feature request at our UserVoice portal - this way the community would be able to evaluate it and if the suggestion gains popularity we will consider its implementation for future releases."

                                      Original request:

                                      We are using mvvm binding to your Chart events

                                      seriesClick
                                      plotAreaClick

                                      both of these events I am unable to determine which mouse button caused the click.

                                      Is is possible…

                                        • Miscellaneous text annotations for all charts in Kendo UI DataViz

                                          We need functionality to allow annotations to charts (e.g. free text).

                                          We need to annotate our charts with text that is:

                                          - not a series value or note
                                          - not a category note
                                          - has no relationship with the plot data
                                          - not a title

                                          An example is text outlining the source of the data,

                                          We have succeeded in annotating charts with Snap.svg.js but the annotations do not survive the imageDataUrl() function for download (or the svg() function).

                                          Axis & series notes won't achieve what we want to do.

                                          We need to place free text (for example) at the top-left,…
