          • Add preload feature to SPA

            Despite the huge bandwidth increases, websites don’t get much faster. This is because the biggest botteneck in loading web pages is latency.

            Latency is inevitable with today’s internet architecture so "cheating" by preloading links you are likely to click on, will speed up a SPA.

            Before visitors click on a link, they hover over that link. Between these two events, 200 ms to 300 ms usually pass by.

            Example implementation: InstantClick makes use of that time to preload the page, so that the page is already there when you click: http://instantclick.io/

            • Allow a Timepicker control to be templated.

              In the normal ASP.NET control, a timepicker can have multiple columns just by setting a property. Not so, with the MVC version. In one of my applications, the time can span all day, so even with 30-minute intervals it can result in a lot of scrolling. I would prefer to have that same property available or at a minimum the ability to assign a custom template.

              • Allow grid via datasource to show dynamically updated aggregates

                Please add the option for aggregates to be calculated dynamically by the datasource without requiring the grid to carry out a full refresh.

                The current workaround from forums is:
                save: function (e) {
                // Refresh aggregates when editing
                e.model.one("change", function () {
                gridDataSource.fetch();
                });
                },
                but as this triggers a refresh of the databound grid, it's current focussed cell is lost.

                Example methodology for expected behaviour of solution:
                1) A Config Flag on a datasource to recalculate aggregates when a value has been changed (only valid when aggregates are calculated locally) - this stops from requiring the save event.
                2)…

                  • NoteText on Chart Series does not show when the data point is at teh top or bottom of the chart

                    Put the below html in http://trykendoui.telerik.com/
                    You will see that for year 2006 the noteText is not visible.
                    Same problem when the data point is at the top of the chart.
                    Should have some option to have some margin to accommodate this.
                    Or better yet change the position of the notetext to top or bottom automatically.

                      • Make the Upload widget bindable to a datasource

                        In order to be able to manage files attached to server objects, it would be nice if we could bind the Upload widget to a datasource.
                        The read() method of the datasource could be used to load the widget with the list of files attached to a given server object.
                        The create() method would be used to upload new files to the sever.
                        The destroy() method would be used for deleting existing files on the server.

                        This would make the upload widget more consistent with other widgets like the combo boxes or the dropdown lists.

                        • When scrolling using Grid Virtualization, Queries are executed twice

                          When scrolling data in a grid using the virtualization scrolling option, the query to fetch the next section of data will occur twice. It does not happen for every query, but it does happen all the time regardless of scrolling fast or slow.

                          • Calculated grid columns

                            Currently, it's very difficult to set up a grid that has a calculated column, where the result is not editable by the user.

                            It's pretty easy to set up a javascript function to calculate and update the value using `dataItem.set("Column", value)`, but this does not work if the column is not also Editable.

                            Currently, you need to hack together some kind of text replacement for the Editor Template, and there doesn't appear to be a simple way to do this from the MVC wrappers. You can create a disabled or readonly textbox, but I'd prefer that it looks like those…

                            • DateTimePicker stepped date and time selection

                              Add the feature to be able to walk through date, hour, and minute selection in a stepped fashion, similar to the functionality of this DatePicker:

                              http://www.malot.fr/bootstrap-datetimepicker/demo.php

                              The gist is to first allow for day selection. Then, with the popup still open, give the user the ability to select the hour of the day, and finally the particular minute of that hour.

                                • Show multiple resources without grouping

                                  There should be the ability to show resources (this is multiple resources) without grouping. All resources will show in a line. This would have worked in our case where we have employees and sub-contractors as two different set of resources but cannot be grouped. We needed to show both the sets on the scheduler at the same time and also assign events across to both sets (so an event can belong to an employee and sub-contractor). The two sets cannot be combined into one resources collection as the resources can have the same Ids

                                  • Kendo UI Editor Table Wizard

                                    It would be nice if we had a Table Wizard (as in RAD Editor) for changing formatting for tables inside Kendo UI Editor (e.g. changing style and color of borders, font and background colors for cells, merging and splitting cells, setting size of the table, and other features that exist in RAD Editor). We're migrating to Kendo UI from RAD controls and Table Wizard for Kendo UI Editor is needed.

                                    Are you planning to implement something like Table Wizard in the near future?

                                      Basic insert/modify table functionality is available in the editor widget (see the relevant option in the first toolbar row here: http://demos.telerik.com/kendo-ui/web/editor/all-tools.html).

                                      Is it that you request additional features to be added to the existing functionality? If so, note that presently this is beyond the scope of our short term plans for editor improvements. The current possibility is to modify the html source directly to achieve your goal.

                                    • extend table initialization for grid

                                      The current table initialization used in grid is not robust and does not supports many features. The main reason is because _columns function in grid does not leverages existing framework functionality. I propose to slightly modify the existing code responsible for parsing column configuration to use kendo.parseOptions instead of working directly with attributes. You can see my re-implementation of this function at [http://jsbin.com/pihefuva/1].

                                      • Grid Keyboard Navigation Problem (please fix)

                                        Hi, Please refer to the following forum for more detail about the problem and my suggestion:
                                        http://www.telerik.com/forums/grid-row-navigation-by-keyboard#ncKqVMBBqUe5ZymNXwpFgg

                                        Summary: I think in Grid widget, there should be difference between selectable="cell" and selectable="row" (for keyboard Up&Down Arrow navigation). or perhaps you want to add another choice, example selectable: "row cell" (to replace the current setting for "row") and the selectable = "row", just select the row not cell and also DO NOT go to grid header!
                                        I believe it's good that you enhance/solve this shortcoming inside the Grid design, because developer like us who has already decided row selection (selectable: "row") during…

                                        • Support Server Side Aggregating When Grid Bound to DataTable

                                          The documentation wrongly says that the grid will perform all server operations of paging, sorting, grouping, and aggregating whether bound to an iQueryable interface or a DataTable (http://docs.telerik.com/kendo-ui/getting-started/using-kendo-with/aspnet-mvc/helpers/grid/faq).

                                          It turns out, after an extensive support ticket, that the documentation is plainly wrong. I have been told that only the COUNT() aggregate is supported when doing server side operations and bound to a Grid.

                                          My request is that this gap in functionality should be fixed so that server operations work for both iQueryable datasources and DataTables.
