Allow using current switch in a trivalent state (i.e. : true,false,undefined)

1. If a detail row is expanded, the entire virtual scroll fails - showing whitespace/not loading new data once you scroll enough to trigger pagination/new dataset load. It remains broken even after collapsing the details row.
2. Scroll down and filter - you see white area. You need to scroll until it triggers data load to fix it.

Hi

It would be great if KendoGrid export to Excel and PDF like excelExport, saveAsExcel, saveAsPDF etc should had options to include all records of the grid and to apply the persistent filters, grouping, sorting etc

Something like:

<kendo-grid-excel fileName="test.xlsx" filteredData="true" allRows="true">

</kendo-grid-excel>

filteredData="true"
Exports exactly what the user has filtered, sorted, grouped, etc. and sees in the view

allRows="true"
Ignores the paging and includes all the data/rows

    .k-coloreditor-header {
        padding: $coloreditor-header-padding-y $coloreditor-header-padding-x 0;
    }

The style rule uses the two variables - with x and y respectively, yet has a hardcoded 0px value as a third parameter.

This causes x to only apply top padding, which is misleading.

Can i reorder tabs using drag and drop in angular ?

How i need to close kendo sortable item in angular? is there any event for that?

so test won't fail if you don't add CUSTOM_ELEMENTS_SCHEMA

The fromDate method of the kendo-intl package allows to use a skeleton format to provide a generic mask that is applied to the current locale.
It would be great to get this functionality for the format string of the date-inputs to gain the possibility to define a locale independent format.
E.g yMMMM will show year and month with respect to the current locale.

Currently, controls are getting their culture from the LOCALE_ID of Angular2 which is set pre-compile time.  This is good and all but there will be issues faced when the application supports multiple countries.  It isn't advisable to create different applications for different countries which have the same functionality.

It would be better if we can simply pass an optional parameter to the control and set the culture that we want to be used.

Date/Time components currently only support date objects for binding, but API calls typically return dates as strings. I would like the option to enable any date/time component to convert strings to date objects during binding. A boolean property such as AllowDateTypeConversion would be nice and allow developers to avoid boilerplate code in all their http service calls.

It'll be awesome if you can have required packages in the package.json file in StackBlitz based on sample. An example, If I'm looking at Kendo Menu sample code in StackBlitz I can just go to package.json and see all the required packages I need to work with Kendo Menu.

To change the topView or bottomView property I have to set the value as string. E.g. topView="month". To be typesave I like to use the CalendarViewEnum in my typescript code. When I bind the enum in the view, the enum-value is set.
But unfortunately the enum value is a number and not a string.
I must convert the enum value like:

public getBottomView(): string {
     return CalendarViewEnum[this._bottomView];
}

Live would be easier if string enums would be used.

Multiple date picker, single date pick, date range pick. Please add all functionality in angular date component.

Same layout as TimePicker, except:
- first part (hours) allows negative sign. Popup will display hours from -23 through 23.
- boolean 'allowDays'. Displays a "days.hours:minutes" format. Negative sign still allowed on first part (which is now days instead of hours).
- boolean 'allowSeconds'. Displays also a seconds part.
- number 'value' property containing the current value. The integer part is days, the fractional part the hours and minutes. (Date object would also be nice, I don't see how to specify a negative value.)

We have a regular need for a non-grid scroller that scrolls over a list of items, virtualizing the instances of the item renderers. The grid does this of course, but it would be quite a hack to implement this for non-grid situations such as a list of cards or panels. Ideally this would work similarly to the grid and support infinite scrolling via the calculated dispatching of pagination events. Also would be great if it supported variable height item renderers. 

The check-box styles for the Kendo themes are beautiful, but they are still static in size. As anyone who has tried can assert, it is very difficult to scale and resize check-boxes, since they don't behave the same way as most other controls.

It would be absolutely wonderful if the Kendo suite had a way to do this, such as ...

```
<form class="k-form">
    <div class="k-form-field">
        <input type="checkbox" id="ch1" class="k-checkbox" checked />
        <label class="k-checkbox-label" for="ch1">Checkbox 1</label>

        <input type="checkbox" id="ch2" class="k-checkbox" checked disabled />
        <label class="k-checkbox-label" for="ch2">Checkbox 2</label>

        <input type="checkbox" id="ch3" class="k-checkbox">
        <label class="k-checkbox-label" for="ch3" [scale]="2">Checkbox 3</label>
    </div>
</form>
```

There is page includes 2 component: 
1. DatePicker with placeHolder is 'placeHolder first value'
2. Button to handle event onChange when clicked.
When the button is clicked, change the placeholder value to 'placeHolder second value'

How to do that with Kendo UI for Angular 2+. ?
Thank you.

Be able to turn off Keyboard Navigation for Kendo Component for Angular 4. (Not just for buttons)

Sometimes, our app may certain key down registered for other events but Kendo's component's keyboard navigation can't be turned off easily and will take over our app's keydown.

For now,  we have to write wrapper for every component that we don't want keyboard navigation like this:
