Columns that do not have a width setting become invisible when one or more columns are frozen.  Our grids have widths for all columns except one column which expands the amount necessary to fill all space in a grid when grid is set to 100% width of the page.  Once frozen columns are turned on, the main column then disappears until a width is added, then there is unused column space in the grid.

For WorkFlow Design 

ListView selectable feature could be done better. One thing has been bothering me. Here's an example: http://demos.telerik.com/kendo-ui/listview/selection Go to the last page and try to select outside of list items. Problem is that it isn't possible. Maybe Telerik has thought that user also has to be able to select text normally. But for instance in Windows Explorer you can begin selection anywhere inside the window and I think the user expects that behavior.

In columns array if you set field attr with a number you'll get an error

Box Plot (Box and Whisker) works great but would like to have Vertical instead of horizontal.

when the mobile view uses a header, containing a toolbar as header it would be nice to be able to have a view title like in the navbar.

When changing visibility of tabs within tabstrip, active tab may become invisible and tabstrip moves to a state when no tab is selected. I think it should be optional to set that I want it to go to the first tab available.

Hide a column in a grid with a detail template

Modalviews have to be defined on the page at startup. It would be helpful if a modalview (and a view) could be returned or replaced as a MVC partial view, i.e. make it possible to create and open a modalview after the page has loaded.

Right now, the only charsets that are supported are UTF8 and ISO/IEC 8859-1.  

Since I have a lot of data to encode, I can get a more efficient output by directly writing a stream of bytes.

We need the ability to get the next occurrence of a recurring event given a start date. This has nothing to do with the scheduler widget but a function that can take a recurring event and start date and return the next occurrence instance (not all the occurrence). We need this to tell the user when they have their next appointment.

I am seeing this bug for more than year ago, it would be really nice if you fix this issue, because it works really very well in Ignite UI, here is the jsfiddle.

I think it would be great addition to add the ability to set KPI's for the grid & pivot grids in Kendo UI. We have used this on you ajaz & mvc controls but are now migrating to a pure html5/kendo ui based website. Please consider this as a feature for your the proposed controls.  

It would be very helpful to have more events on every controls and better event arguments on existing and future ones. This include things like click events that could be listened with a standard event binder with proper selector. We don't want to figure out what the selectors has to be.

This would dramatically improve the customization of Kendo controls, which I find very hard to deal with in the current state.

In help text at:

Kendo Grid 'locked' help text needs link to 'Frozen Columns' - can't find any help.

Right now on a mobile device it will put just what it needs into the overflow box. I would like to see the ability to force everything into the overflow when it is activated at all.

Make the Kendo UI Dojo embeddable via an iframe. Exactly what jsfiddle.net offers.

Currently I am using v2014.1.416.
I am binding mouseup event with below code.
$('#' + mainId + ' div.k-splitbar').live('mouseup', function(e){
            setTimeout(function () {
                if ((typeof ($fujicracommon) != "undefined") && ($fujicracommon != null)) {
                    $fujicracommon.handleVesselResize();
                }
            }, 200);
        });
