Some users prefer larger font sizes than what is default in kendo. We have added an option for setting the default font size in our product, but when we do that some of the widgets brake because they did size calculations on init that is affected by font size changes.

We currently have to reload the entire page as a workaround, but that does not offer the user a smooth experience when changing the font size. At minimum, all widgets should support a resize method that we could trigger such that the widgets could recalculate all required sizes.

Today you can only export JavaScript primitive values - String, Number, Date, Boolean.

I'm writing a application and would love to have 'pull to refresh' activated when the user swipes up instead of down.  In addition, endless scrolling would work when swiping down instead of up.  Basically the reverse of how the listview works right now.  

I see this request often and users end up implementing their own solution.

Modal window does not currently work properly with MVVM. When visible = false, the modal area is still visible.

Several of your controls (Scheduler, Grid) make use of the Validator control for validation on the edit forms.  Once the validator is loaded there is no way to change the options.

It is important if the validator is going to be embedded within other controls that we be able to enable/disable validateOnBlur and get/set the errorTemplate.

Without the ability to change the validator options, support recommends use of private methods.

An alternate choice would be to require those controls that are embedding the validation to provide these options as part of their configuration.

Thanks

There are as many real world situations where one needs to display Heterogeneous Hierarchical Data such as web services where the returned data has complex data types consisting different simple type data or list.

Kendo Grid Row Filters inputs use autocomplete by default. Because of this the data source is queried on every keystroke in the auto complete. This causes unacceptable performance issues with a large/complex server side data source. I suggest adding a configuration to turn this off, which would cause the data source to only be queried on an enter keystroke.

When integrating the Kendo UI Editor with other components, it would be nice if there was more visibility and control on the state and actions of the Kendo Editor.

For instance, bind 2 new callbacks/events: 
- onClose: function(event) {}
- onOpen: function(event) {}

Methods to control the Editor externally:
- editor.close()
- editor.open()

Methods to inquire on the Editor's state:
- editor.isOpen()

The Drawer widget doesn't work in Intel XDK emulator. It works fine on the device using Intel App Preview, but not being able to select an item from the drawer in the emulator kinda is a show-stopper for navigating the app.

we need the polymer js which is used in Kendo UI
like Angular js we need to use Polymer also

Add support for cell.formula on Woorbook

Having a character counter for textbox & textareas gives users nice little heads up as they start typing to summarize the text for a fixed length. Not sure about internet applications but its becoming more & more a requirement in business applications. Please give it a thought.

the only way to style only the mulitselect dropdown list differently than other dropdown lists is to run a js script to add a css class...

  function setupMultiSelectULStyle (styleName) {
    var selects = $("select");
    $.each(selects, function(index, item) {
      var data = $(item).data("kendoMultiSelect");
      if (data !== undefined && data !== null)
        setupMultiSelectULStyleSingle(data, styleName);
    });
  }

i think if you are creating elements that are not wrapped in parent element style they should have some way to style by parent control type differentiated css selector


<div class="k-list-multiselect k-list-container k-popup ... " id="..." >
<div class="k-list-dropdown  k-list-container k-popup ... " id="..." >

The library is getting pretty big - lots of great features, but still big.  I would love to see the team take some time and offer more options to reduce the size of the ALL and CUSTOM builds.  Perhaps look to drop old browser support and do a pass on tightening things up.  Set a goal for the team to reduce the library size by 10%.

Currently the calling .hide() on a Kendo UI Notification hides all of the instances of that notification. It would be useful to have support for hiding a specific instance, perhaps by 'ID'.

I've accomplished this by using the .getNotifications() method and iterating over the notifications to find the one I wish to close, however built in support would be a timesaver!

There are times when it is not obvious that the Listview contains more records than are displayed. It would be nice to have an optional indicator that there are more records above or below the current scrolled view. Another option is to keep the scrollbar turned on.

After I filtered a column and deletes the filter content and press again the "Filter"-Button, nothing happens. Filter with empty string should clear the filter on the column,

I have a very simple chart, with date category axis, 2 series with just 2 values (two days). I set rotation for labels on a category axis to 45.
When any "label" in a legend is clicked, the labels disappear.
This problem appears only if rotation is set to 45. I have tried to set rotation to 40 or 90 - both are just fine. But rotation 45 seems to be broken.

We recently implemented a bubble chart for our system. The users loved it but wanted to see custom markers that would indicate "direction" of the data value. We couldn't see a way to put custom markers on the bubble chart (hence the term bubble I guess) so we looked at the scatter chart. This did everything we needed (custom marker, relative sizes, etc) but did not allow us to click on a marker that was behind another (like the bubble chart). We would like one or the other.
