Some of us use custom cell editors with multiple checkboxes (or other multiple inputs) and right now we can't use the data-bind syntax to automatically update the model when the user moves away from the cell. We also can't use the grid's "save" event because it won't fire.
Please add support for the grid column to bind to arrays, OR at least let us specify in the model or grid declaration that we want the "save" event to fire (even when you wouldn't normally do it).  This event would allow us to manually get the values of all checkboxes and update the model.

It would be like to setting the Edit Row and Filter Row to support checkbox without ClientTemplate. It is a very very common editor type for boolean field.

Similar to http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/alleditablecolumns/defaultcs.aspx or http://demos.devexpress.com/ASPxGridViewDemos/GridEditing/EditForm.aspx

We now have operators that support filtering for null/empty values in grid columns.  These are available using the standard Filter Menu, which provides input fields and the operator dropdown list.  Our users really love the Multi Checkbox filtering, which allows them to choose any number of possible values at the same time.  The missing feature is that the Multi Checkbox filtering prevents us from finding the "empty" rows.

Much the same way that "Select All" is automatically added to the list of checkboxes, please add some sort of "null/empty" item to the list.  It would be great if this was configurable.  In some of our columns, it's not possible to have empty values, so it doesn't make sense to include the "empty" checkbox for those columns.

Be sure to handle scenarios when the data source is automatic based on the data in the grid and when a separate, custom data source is provided for the column.

Hi, we use the grid "toolbar" property.  But, we found that the documentation of the kendoToolBar "standalone" offers more possibilities, like adding a type "separator", groups, toggle, ...

My question is:
When I create my grid, is it possible to get a reference to its containing kendoToolBar (if it's a complete kendoToolBar ?), that allow to add more complex items.

Something like: 

var kgrid = $('#grid1').kendoGrid({toolbar: [...]}).data("kendoGrid").

var kToolbar = $('#grid1 .k-grid-toolbar').data("kendoToolBar") // or kgrid._secret_property?

kToolbar.add({type: "separator"})

I tried that, but the kToolbar is undefined.

Please add out of box functionality ( MVC and Kendo ) for simple search panel like DevExpress :

In a Kendo grid, Angular/MVC/JS/Whatever; 
When using multi check filter. 
---- 
Only show those values that are still useful to filter on!!! 
---

When filtering is done(one to many columns) - ONLY the remaining options should be seen when setting the NEXT filter (not all possible values in the database) of course distinct and sorted

(the grid could have an option of doing it this way or the old way) 
example:

let's say we have 5 numbers of categories, each category have 20 different details.

when filtering is set on one category, then when filtering on details - only the 20 remaining details should be seen, not 100(5*20)

and vice verse, if filtering one detail - only one category should be seen when filtering on category.

Currently its possible to set static attributes or CSS classes to kendo grid columns by specifying then in column definition:

var columns = [{ field: 'someData', title: 'Some Data', attributes { 'class': 'some-css'} }];

Please add possibility to add custom attributes or CSS Classes dynamically (depending on data row):

var columns = [{ field: 'someData', title: 'Some Data', attributes { 'class': function(dataRow){ return dataRow.data > 1 ? 'css-go-up': 'css-go-down' }} }];

Just similar how it works with template for column.

Thanks,
Val

Grid should allow to place images in the header of each column instead of text on per column basis.

I realize the grid's batch save is asynch, but most every project I work on has a need to know when grid saving is complete.  Right now you can know when each of the CRUD operations is complete, but not when ALL are complete.  Please either add an event for when ALL are completed, or give us the option to have the grid send ALL CRUD operations to the server at one time.

I have recenty found that if users include <html> tags in fields in a form, and this data is then displayed in a grid, if the user then groups by that column, raw html will be displayed. The "suggested" way around this potential huge security flaw is to use a group header template for every string column, ensuring the value is displayed encoded using ${value} instead of the default #=value#.

The default for a cell is ${value}

When using multiple sort mode in a grid, visualize the sort order in which the grid is sorted. For example, displaying the sort order as 1,2,3,.. on the respective column headers. Without such an indication the user has no idea what sort order has been used.

Please add horizontal navigation with arrow keys when the grid area is smaller than the container window and there are scrollbars. See demo here: http://jsfiddle.net/epqR4/. The vertical navigation with arrows works fine, but horizontal does not.

sometimes you use same data which presented with grid and chart, but sometimes it need to be grouped by different categories such as in chart or grid, the problem is that you need to map data between categories in the chart and the grid

Bug report

ColumnMenu in Grid does not hide/unhide the correct column when command column is placed first

Reproduction of the problem

1. Open the Dojo
2. Open the columnMenu for one of the columns
3. Try to select a column, for example "Unit in Stock"

Current behavior

Currently, the previous column is checked/unchecked and respectively hidden ("Unit Price")

Expected/desired behavior

The column that is selected in the columnMenu should be hidden or displayed and checked/unchecked in the columnMenu

Environment

• Kendo UI version: 2020.2.617
• Browser: [all ]

Basically, when a boolean is placed in a grid, it displays true/false.  It would be better to show it either checked/unchecked.  There is a template to be used, but it has a couple of issues:
1. you need to define it for every check box
2. It is either enabled or disabled.  Ideally, it should be disabled in display mode, and enabled in edit mode.

We are using the grid primarily to view paged sets of data, so in most cases we will see 10 to 25 records at one time.  Regardless of the number of records visible, the vertical scrollbar appears in a disabled state.  From my understanding, grid scrolling is either on or off, there is no Horizontal:On, Vertical:Off capability.  Our users often see multiple grids per page and the presence of these useless scrollbars creates visual clutter.  I am requesting the ability to independently set the visibility of the vertical and horizontal scrollbars on the grid in such a way that the grid's header and footer adjust to fill the empty space created where normally the scrollbar offset padding (17px) applied as an inline style in the _scrollable method of the grid javascript.  I envision this working via the kendoGrid settings object like so:

{
...
scrollable: { x: true, y:false }
...
}

In a navigatable grid with row selection mode, It should be possible to focus row using arrow keys (up or down) instead of space bar.

Right now when user press arrow keys, only once cell is being highlighted and focused. If user wants to highlight that row then he needs to press spacebar.

this behavior is confusing for end user.

Currently, kendo-styled checkboxes are not rendered for the default column editors for Boolean columns.  Instead, default browser checkboxes are rendered.

In addition, kendo-styled checkboxes are not supported (and indeed do not function correctly) in custom column editors.

This issue creates a styling consistency "blemish" on pages where we've otherwise been totally consistent with a Kendo theme.

Please alter the grid behavior so that it both renders Kendo-styled checkboxes for the default Boolean column editor, and allows them for custom column editors.
