Add an beforeOnchange event that fires to allow additional validation before the change occurs. If returns false then onChange never is fired.

Add property that defines a delay before requesting new items when scrolling. 

This would prevent sending multiple request when dragging the scrollbar and passing more than one page.

Add ability to have a horizontal scrollbar in the kendoui grid that appears at both the top and bottom of the data set to ease scrolling in large data sets.

The popup dialog used by the Grid control does not match the Dialog control. With the same theme applied, the title bar is different (height, font size, and close button), and the button bar footer layout is completely different (button shape, size, and location).

By default, dialog look & feel should be consistent across controls using the same theme.

The new event should fire as soon as the grid is fully rendered und ready to take user input or focus.

We need this for automated UI Testing. SetTimeout does not work reliable.

Frozen Columns is a really useful addition to the grid, but we're not able to implement it at present as we don't want to force our users to always have one column locked.  We don't want to dictate which column that should be, e.g. fixing the LH column.  

If we could enable Frozen Columns giving the user freedom to freeze one or more columns of their choice, that would be ideal. 

would be useful

Currently in a data grid with virtual scrolling there is no way to scroll to an item. You can filter to that item, but you can't see it in the context of other data. I'm pretty sure this was available in Silverlight rad grid 7-8 years ago.

If you export your grid to Excel then you may have noticed that sometimes the columns are smaller than their content.
What I mean is, I have double click the coumn header in Excel to get the desired "auto-width".
It would be nice to have this functionality already in Telerik.
So that the column width perfectly fits its content.

We were interested in an option for aggregation rows on top of kendo grid groups. Now they are by default on the bottom of the group which some business users don't like.

Adding the same functionality as filterable.extra but in row mode. Similar to the following demo http://dojo.telerik.com/AkaYi/2.

Currently when using MVVM to instanciate a grid which contains columns with values arrays, those values arrays must be globally scoped.  All other things MVVM binds to are located within the View Model.

Please make it so that the kendo.bind method will allow for an MVVM grid to locate it's columns value arrays within the View Model. 

In the JQuery Grid if you have the following column definition (for example):

[
    {
        "field": "Name",
        "title": "Name"
    },
    {
        "title": "Address",
        "columns": [
            {
                "field": "Street",
                "title": "Number & Street"
            },
            {
                "field": "City",
                "title": "City"
            },
            {
                "field": "PostCode",
                "title": "Post Code"
            }
        ]
    },
    {
        "title": "Contact Details",
        "columns": [
            {
                "field": "Email",
                "title": "Email Address"
            },
            {
                "field": "Phone",
                "title": "Phone Number"
            }
        ]
    },
    {
        "field": "DOB",
        "title": "Date of Birth"
    }
]

When you drag the multi-column header "Address" and drop it over "Date of Birth" the header and it's child columns move as expected but the column headers in the two multi-columns get mixed up.

This only seems to happen when dragging a multi-column past another multi-column in either direction.

Show the text in the filterMenu formatted as the text in the column. More info here: http://www.telerik.com/forums/filtering-html-characters

Currently, when kendo grid is initialized from an  already populated html table, there is then no way to freeze columns as there is no datasource specified in kendo grid initialization.

kendo grid dynamic does not contain a definition for MinResizableWidth throwing this error on resize column ..multiple dynamic gids in my mvc view 

minResizableWidth float
The pixel screen width below which the user will not be able to resize the column via the UI.

Bug: Column Resize Handle not showing on dynamic Grid Columns

The problems are the hidden columns. If you have a hidden column in the grid, you can't resize all other columns after the hidden column. That is a very nasty bug, so please Kendo-UI team make a fix for it.

It would be helpful to be able to format a grids content in a more straightforward manner out-of-the-box. For instance, if a Kendo grid was displaying a typical data matrix like https://en.wikipedia.org/wiki/Triangular_matrix, it would be useful to be able to format by the upper triangular region, lower triangular region, odd rows, even rows, etc.

KendoUI Grid persist row selection state after update a field programmatically via the set method of the dataItem.

When using a template for Grid PDF export, usage of AngularJS scope variables should be possible, e.g. to customize the title.
