  1. provide more information in groupheadertemplate

    The event args from column.groupHeaderTemplate (and groupFooterTemplate) should contain a function to retrieve the data for that group. Currently, they only contain "field" and "value." If you made the grouped rows available in this event, clients would be free to add multiple aggregate columns of the same type (i.e., get the "sum" of multiple values instead of being limited to a single value). I've been able to halfway implement this, but it only works correctly if I'm only grouping by one column. For example, if I'm grouped by WidgetName and then by ProductCode, my event args for ProductCode should contain…

    • More Grid Events

      I'd like to see an event for Grid contents modified (after-edit or after-add/delete, etc). This would enable a sync with a DataSource, for instance, without further user action. Presently, this is not easily achieved.

          • Event for switching grid from edit to view mode in case of incell editing

            Currently Kendo UI grid don't have any way to know that grid changes its mode from edit to view in case of incell editing.
            As per thread (http://www.telerik.com/forums/is-there-any-way-to-know-grid-edit-mode-changes) we have to add blur/focusout event handler to know changing mode. But some time it happen (in case of adding custom widgets through columns editor) that blur/focusout event triggered but still grid is in edit mode.
            Its better to have an event when grid changes its mode from edit to view so that we can minimize issue mentioned above.

            • Excel like Filter - respect other filtration applied

              Excel-like filter always show all available options.
              When one filter was already applied - could we limit number of options to see only options that are left after previous filtration?

              We should be able to filter only by already filtered rows.

              As alternative - could we have some event on Excel-like filter to populate options for it every time it expands?

              • Maintain dirty indicator on batch edit grids

                Currently if you add a row to a grid in batch edit mode any rows that have already been edited will lose their dirty flag indicator. I would like for Kendo to handle maintaining the dirty flag for these rows. If there is a performance concern with adding this functionality, then maybe there could be a setting to turn it on or off.

                  A possible option might be to utilize the solution presented in this help topic:
                  http://docs.telerik.com/kendo-ui/web/grid/how-to/Editing/preserve-the-dirty-indicator-in-incell-editing-and-client-operations

                  Alternatively, if you rely heavily on spreadsheet-like batch editing capabilities combined with row insertion, you may contemplate using our new spreadsheet widget for this type of UI presentation and interaction:
                  http://demos.telerik.com/kendo-ui/spreadsheet/index

                • Grid: Add an easy way to hide command buttons based on model data

                  Very often in grids we want command buttons disabled (or not even visible) depending upon model data, such as Delete not being available if the data has certain values set. Something like:

                  columns.Command(commands => {
                  commands.Edit();
                  commands.Destroy().VisibleIf(model => model.IsPosted)
                  });

                  Using HtmlAttributes would be acceptable if it was easy to access the model. I'm currently achieving this by using a client template and rendering the buttons myself, but this seems overly complex for what is a simple occurance.

                    • Change Style of deleted row rather than removing it, Grid Batch Editing

                      Currently we use batch editing in the Grid control. The idea of batch editing is all changes are retained client side until the user presses the save button.

                      When editing a cell a red dirty indicator is placed on the cell. This gives the user an indication that there are unsaved changes. however, when deleting a row, the row just goes away. There is no indication the user must still save.

                      I would like to see rather than the record immediately removed a class applied to the row so we can apply some style like a strikethrough or red background…

                              There is an option to freeze the left most column of the Kendo Grid by setting the lockable property.
                              But this is limited to the Left Hand Side columns only and there are no ways suggested to freeze the Right Most columns.

                                  We will monitor the interest in your proposition. For now you may consider disabling the editing option in each fo the rows on demand programmatically.

                                • Add posibility to jump (scroll) to specific row when using virtual grid

                                  When using Grid with virtual scrollbar there is no possibilty to go to sepecific row programaticly. Especially for row that are not yet loaded.

                                  I have managed to move the scrolbar using

                                  grid.virtualScrollable.verticalScrollbar.scrollTop(scrollRow[0].offsetTop + pageOffset * pageIndex);

                                  however the calcualtion of the location of the row is impossible when rows have dynamic height.

                                  • Add the ability for Kendo Grid's "colum.values" option to accept either an array of column values, or a function that returns the array

                                    Currently, Kendo Grid has a "column.values" option that accepts an array of key/value pairs. These values are used to render human-readable text for fields that are foreign keys. Depending on how the grid is used, this array of "available values" could be dynamic. Currently, there is no way to update these arrays without calling "setOptions" manually with the new, correct column definitions.

                                    To fix this, Kendo Grid should track changes to the "column.value" array (via some sort of observable or something - I'm not sure exactly how things work under the hood). Alternatively, "column.values" could also accept a function. This…

                                    • Fix a new grid multi-sort

                                      Right now there are two options for sorting, single and multi-column. We would very much like to use the multisort version, however our users fail to understand the functionality. We suggest a new setting, "ctrl-multisort":

                                      Single-sort when clicking and multi-sort when ctrl-clicking, similair to most desktop grid controls.

                                        We are needing the virtual scrolling to work for our project and also need the detail rows working. The explaination of the problem was described on the forums here:

                                        • 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.
