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.

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.

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.

When the grid is grouped, the grouping column is visible with the same values in each cell of each group. Looks weird and confusing.

How can we accomplish more efficient look and hide the grouping column?  http://demos.devexpress.com/aspxgridviewdemos/GroupingSorting/Grouping.aspx

With a batch edit grid, it would be nice to have the ability to cancel a data operation if cells have been edited.  Currently if the user edits some cells and then does a filter or paging operation before they save their changes, there is no way to warn them and prevent the operation from taking place.  So they will lose their changes.  Ideally, I'd like to have an event that fires before the read() operation is called on the datasource which would allow the read to be cancelled.

Currently you can clone the Pager to make it appear both on Top/Bottom. This should be configurable so that you can have in on top of the grid or the bottom of grid or both

Searching by date range is a very common use-case in most business applications. I need a From and To calendar controls in the row filter.

I would advise Telerik to put this functionality on the roadmap, else the row filter functionality is so restrictive as to render it useless. 

I am having to roll my own filters above the grid because of this one omission which is a real shame because the rest of the Grid functionality is so good.

(I don't want to use filters in column headers because I don't like the fact you loose visibility of what filters are on - probably the reason for the grid rows introduction)

The current implementation of Persist State http://demos.telerik.com/kendo-ui/grid/persist-state isn't meant to save the user state of the grid.

Let me explain.
Currently setOptions() override the options in the grid. That has a rather unfortunate side effect. The Column[{...}] options coming from the server is no longer used (ever) as all column options are now coming from the client. Effectively overriding all column options.

Example:
{
   ...,
   columns: [
      { field: "Name", filterable: false }
   ]
}

This is saved using the current persist state.
Later the backend now supports filtering of the "Name" field, and we change filterable to true. The user will not see this change. Because it's overridden with the column options stored on the client.

It would be nice if this wasn't the case.
Either make a new method get-/setUserOptions() or change the current get-/setOptions() (I cannot figure out the usecase for the current implementation as it to me always would be used for what I've described here - and do a poor job of it)

However we also need to recognize that different options have different life cycles.
For example would I want to save current page, sorting and filters in sessionStorage.
While column order, size and pageSize (don't override, just set. As the range can change) would be saved in localStorage.
So that need to be easy to do.

The last thing we need is an event where it would make sense to call setUserOptions(). For the purpose of loading saved state without having to click a "Load state" button. The event needs to be before the datasource is quried. 
The current dataBinding event doesn't work as it would result in an infinite loop of datasource queries.

It would be really great if Kendo implemented JQuery Promises on all methods that are fired asynchronously. There are several places where there would be direct and tangible benefits:

1) DataSource: Methods like fetch() and read() would be able to chained with .then(), .fail(), and .always() in order to complete certain operations after these methods have completed, but before events are fired up the chain.

2) UI controls like Grid: calling KendoGrid.saveChanges() would allow you to chain a .then() function to the end, so that a particular function can be called only when a particular instance of saveChanges completes, not every time the requestEnd event is fired on the DataSource.

Currently, If I use Kendo Grid on a page with 10 column by 10 rows(and have 3 rows in editable mode & 7 rows in disabled/locked mode). I can not navigate through grid control via TAB key with only Enabled columns. It still go through each control.

Logging to support request, I am being advised that I need to impalement my own TAB logic. However, if you think, it doesn't make sense for TAB to be stopped at Disabled column.

It is probably stopping as Kendo doesn't have any direct mechanism of disabling some columns for edit. I wrote some Jquery which doesn't let us click on some column and I used CSS to make it look like disabled. 

It is nice if ClientTemplate allows facility where we can enable/disable controls and TAB key respect those.

To me these are all glaring bugs, especially for those who like to use their keyboard instead of their mouse to fill out forms.

1. Mouse scrolling drop downs/comboboxes scrolls the page when it hits the top/bottom.
2. Enter key opens/closes subgrid instead of putting cell into/out of edit mode.
3. Backspace in drop downs causes browser to go back to the previous page.
4. Comboboxes, when filtering, should always "select" the highlighted item when tab is pressed.(the little auto-complete hack/setting doesn't cut it)
5. There is no easy keyboard way to open drop downs and date pickers in the grid.
6. Tabbing to a button cell and hitting Enter does not click the button.

My Kendo grid has long column titles but the column width must remain static so we need a way to make a wrapable column header

When we have a Grid with Resizable Columns we may need some of them to be non-resizable (ex. a column containing only status icons).
There are work around and customizations:

Column Resize - Min Width on Resize
http://www.telerik.com/forums/column-resize---min-width-on-resize

but I believe it will be more handy to define requested behavior as a property of the specific column (ex. in row template).

Also, for non resizable columns the user should not even take a resize handle when going on a non resizable column boundary instead of try to resize and when the user leaves the resize handle the column is bouncing back (restoring) the minimum width defined.

"NoRecordsTemplate" - At present a small text is being shown at the bottom of the grid if there are no records which is not prominent. please add back the NoRecordsTemplate so it can be displayed inside the grid and can be customized

"Clear all filters" - It is very tough to clear filters one by one please all clear all option

Currently, pressing the arrow keys will scroll up and down the grid. It would be good if we could also use the arrow keys to change the selected row

Based on the examples here (http://demos.telerik.com/kendo-ui/web/grid/editing-custom.html), "incell" editing allows editing a single cell at a time. The edit mode is activated upon a single click in the cell.

I would like to have a way to combine this with "cell" selectable mode, e.g. like this?
* A single click on a cell selects the cell and fires the "change" event.
* A double click on a cell activates the edit mode for the cell.

For string columns especially, the default type of filter someone would want to apply is not the first option in the list. If it's not possible to reorder the items, then it should be possible to select which item is the default. This would prevent users from having to change the filter every single time.

It's a common scenario to set custom css on <td> for specific column, for example, using columns: { field: "ScoreNumber", css: "right-align", title: "Score" } to get <td class='right-align'>, then I can make every every score field text-align: right.

Maybe adjusting _tmpl: in Grid Widget as 
rowTemplate += "<td" + (column.css ? " class='" + column.css + "'" : "") + ">"; is a easy way to accomplish it.
