  1. A TreeView in ComboBox - once again

    A TreeView in ComboBox would be most helpful as both a stand-alone control and when editing within the Grid.

    something like this: http://www.brad-smith.info/blog/archives/193 (example from .NET Windows forms world)

    * Used for relative small tree data structure.
    * User may select one (many) item(s), without _loosing context_ (no interrupting dialog box, 'flat' interface).
    * User may accept selection by click on item, or pressing 'enter'.
    * User may cancel (hide) popup when click outside control/popup (ie in another control, that received focus) or pressing escape - like in combobox/dropdown.
    * It will be nice if user can select items using…

      • UI Web Listview Endless Scrolling

        Just like in the grid and mobile listview, i would like to see an endless scroll option (or serverside paging with virtual scroll) in the Web version of ListView.

          Petyo IvanovPetyo Ivanov responded

          Hi everyone,

          We reviewed the suggestion and its implications. Unlike its mobile equivalent, the Web ListView does not impose any restrictions to the items layout. This means that the complete implementation of this feature should work pretty much like https://www.pinterest.com/ (warning – the site may feature partial nudity or other explicit content on its home screen).

          We identified the following features:

          - multiple items per row
          - Items with different height, which seem to feature some distribution algorithm
          - virtualization – Items that exit the viewport are removed from the DOM
          - reordering and persistence on resize

          In addition to the above, we are aware of requirements such as:
          - fixed headers
          - support for deep linking / scrolling to a given item

          Worth mentioning is that complete, reliable support for the above requires an adequate back-end implementation, and, most likely a specialized data source implementation.

          Based on our experience…

        • Vue.js integration

          This is a great framework that takes the best ideas of angular and react without being as difficult to learn as either of them. Please consider it.

          • Area-range chart series

            For example; similar to http://www.highcharts.com/stock/demo/arearange

            Having area 'scatter' support, such as 'scatterArea', and 'scatterAreaRange', like the existing 'scatterLine', is also desirable.

            • Built in PDF Viewer control for Both Kendo UI and Kendo UI Mobile

              It would be nice to have a built in PDF viewer control in the Kendo UI and Kendo UI Mobile. Especially Mobile so we do not have to search the net for decent controls that may or may not work for the different devices.

                  This feature would require support for item templates in the menu. Presently we don’t have immediate plans to support this functionality.

                • Improve performance for large TreeLists (virtualization)

                  As discussed on the forum (http://www.telerik.com/forums/virtualization-for-treelist) please improve the rendering/scrolling/expanding/collapsing performance of TreeLists with many expanded rows.

                  Grids support virtualization and work well with hundreds of thousands of rows (http://demos.telerik.com/kendo-ui/grid/virtualization-local-data). Perhaps virtualization can be added to TreeLists to achieve similar results?

                  • TreeList column groups

                    Much like how the Grid has column grouping, it would be nice if the TreeList had this as well.

                    • Add multiple date selection & more events to Calendar

                      Add a multiple date selection to the Calendar. A multiple date selection calendar is very important for professional web applications in many situations. Also, there is a lack of events in the API.
                      It is always important to provide more events then less.

                      Here a few suggestions:
                      Property year; /// Year displayed by control.
                      Property month; /// Month (1 to 12) displayed by control.
                      A method in the API to easily get the selected date(s).
                      A method in the API to easily set the selected date(s).
                      An option to indicate if we allow/disallow multi-selection.

                        • ImageBrowser as a standalone widget

                          I've been playing around with the ImageBrowser (Editor) and would love to see a variation of the ImageBrowser as a standalone widget. If I could use it without the Editor to simply select or upload an image file that would really add value to some of my applications (for which I now have to use a different tool: elFinder).

                          Since the ImageBrowser already exists, hopefully this would be an easy addition to the KendoUI toolset! :)

                          • Add Right To Left PDF support

                            Kendo UI supports PDF export. It would be great if you could add glyph mirroring support to it as well (https://github.com/mozilla/pdf.js/blob/master/src/core/bidi.js). PDF export of RTL languages such as Arabic and Persian need this trick to work properly.

                                • .Where, .Select, .Single, .OrderBy, First on ObservableArray

                                  It would be exponentially helpful if the "ObservableArray" implemented some basic "Where/Select/Single" methods. This would assist in searching through them and give Kendo UI a much needed facelift in the array department.

                                  Behavior would be, theoretically, as follows...

                                  var viewModel = kendo.observable({
                                  Users: [
                                  {
                                  id: 1,

                                  • Vertical Grid / Property Grid

                                    Add a new Kendo UI component to display a record vertically (Or add an option to the existing grid to change the orientation of the records).

                                    Usually, I was using vertical grid to display a single record but some people might need it to display more than one record (ex: when you compare items on best-buy web site)

                                    The vertical grid could also be used as a property grid (http://www.telerik.com/products/silverlight/controls/propertygrid.aspx).

                                    • Marker Clustering support on Kendo UI Map

                                      Add marker clustering support to the Kendo UI DataViz Map control.
                                      If you are viewing a map with many markers nearby, they should group together so that the map is more pleasing to the eye.

                                      This functionality already exists in the Telerik Silverlight Map control and it would be great to see similar functionality here.

                                      Here's an example of what I want: http://demos.telerik.com/silverlight/#Map/Cluster

                                      • kendo grid foreignkey binding against a remote data source

                                        Ability for a grid to show foreign key values from a remote datasource rather than just a fixed array.

                                        Refer to: http://www.kendoui.com/forums/ui/grid/foreign-key-option-doesn-t-work.aspx

                                        • Crop and resize gui widget for images

                                          At typical usecase for web applications is to let the user upload and image (portrait, avatar, picutre of real estate etc.) and then resize and crop it to a specific contrain.

                                          An easy widget for handling the cropping and resizing might come handy for many.

                                          There are solution for cropping and also resizing in jquery plugins already, however a successful and pretty combo of the two seems to lack a bit.

                                          Inspiration:
