When the user open with pc or ipad (or bigger screens) then the TabStrip is fine. But when he opens the page with mobile phone its better to have no Tabstrip at all and just have the content pages one after the other with some heading.

Please consider adding feature which implement times series graph similar to "Google Finance stock view".

This will give user multiple zoom options like 10 day, 1 month, 3 month, 6 month, 1 Year and All period.

Then user can see line chart that will reflect user's zoom selection. User can scroll through to see historical data. 

It would very nice to have official ReactJS binding for Kendo UI.

I miss being able to preview the mobile widgets in the different themes, could we get a theme switcher for the Hybrid UI demo?

For Kendo UI, it would be great if you could add a kendo configuration to a Model's field which would be used to auto display the html component, here is an example:

var newModel = kendo.data.Model.define({
  id: "id",
  fields: {
    state: {
      type: "string",
      defaultValue: "",
      validation: { required: true },
      component: {
        role: "kendoDropDownList",
        dataSource: {
          data: [
            'Alabama',
            'Alaska',
            'Arizona'
          ]
        }
      }
    }
  }
});

Any plans on releasing the Nova theme for Kendo UI Web? I really like the Flat theme, but something less round but still colorful like Nova would be great!

You can put multiple inputs in a custom Grid cell editor (textboxes, checkboxes, etc.), but since there's more than 1 and the grid doesn't support binding to arrays/collections out of the box, there's no way to automatically get those values into a model when you move away from the cell. The grid "save" event doesn't fire when there isn't 1 input using "data-bind".
You can put a button or something to click on inside the cell and then in the click event update the model yourself, but that looks odd.
Please add a cell-closing event that allows us to manually update the model or do other clean-up.
OR, please add support for binding to arrays for a field in the grid.
Thanks. 

When a chart is exported from an application, the source is not very clear. It can be written in the author property, but that is not visible. 
I would like to be able to create page header/footer.
I can export a PDF page with custom layout using a DOM selector, but in that case the output does not includes paged data in for example a Gantt chart

When window resize , detect all components in it and resize 

The ToolBar widget should provide full keyboard navigability. 
All buttons and split buttons should be accessible using the tab key.
All menu buttons should be accessible using the arrow keys when focus is on the associated split button.
Pressing the enter key should execute the buttons' associated functionality.
The toolbar's overflow menu should support keyboard navigation.

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.
