Describe the bug
When using the GridPdfExport component for exporting Grid data to a PDF file the exporting operation fails with the following error:

• The issue is replicable only when working in Vue 2 context

To Reproduce

1. Open this CodeSandbox example
2. Click the button above the grid

Expected behavior
A system dialog should appear asking where the generated file should be saved

Describe the bug
The color of the Gauge component is not reactively updated when the value passed to its pointerColor prop is updated.

To Reproduce

1. Open this StackBlitz example
2. Change the selection in the radio buttons

Expected behavior
The color of the Gauge's pointer should be changed every time the selection in the radio buttons is changed

Screenshots

The current implementation of the Native Slider component allows you to select a value that is between the labels defined for the component(see the following screenshot). 

If, in the above scenario, we have Slider labels like 0, 1, 2, 3......etc, the user can select a value of 1.5, for example.

Providing an option that prevents the selection of a value that is between the values of the Slider labels will be a very nice property for the component. 

Currently, the described scenario can be implemented using the Slider in controlled mode as demonstrated in this StackBlitz example, but having the functionality out of the box will be more valuable for all users.

Describe the bug
The modal property of the Window is supposed to control if there is a layer behind the component that prevents or allows interaction with the elements that are below the Window.

Currently, there is no way to click the elements behind the Window.

• Possible workaround is demonstrated here. The workaround uses the following CSS:

.k-dialog-wrapper {
  height: initial;
  width: initial;
}

To Reproduce

1. Open this demo
2. Try to click on the "Close Window" button

Expected behavior
If the modal property is set to false, the user should be able to interact with the HTML elements behind the Window.

When I try to drag or scale a tile, a line is displayed to indicate where it can be placed (red line in the image)
Can you add an option that configures the visibility of the split grid lines (dividing columns)? (Image blue)

Describe the bug
The is a slight bouncing of the DatePicker's popup when it is opened above the input of the component

To Reproduce

1. Open this StackBlitz example
2. Open the popup of the DatePicker

Expected behavior
The popup's opening animation should not have any bounces

The design available in the Kendo UI for Vue Native DatePicker is different from the popup of the KendoReact DatePicker. 

Can you provide KendoReact's DatePicker design in Vue? Here is a screenshot of what I need:

Describe the bug

Highlight some text in the Editor. Set a font colour other than black, then use the Underline tool.

Once underlined, the text decoration is not the same colour as the text.

To Reproduce

1. Open https://codesandbox.io/s/great-rosalind-43wdd0
2. Highlight any text
3. Change the font colour to anything other than black
4. Use the underline tool to underline the highlighted text
5. Deselect the text and the text decoration and font colour do not match.

Expected behavior

The font colour and underline colour should match.

The current implementation of the Native Chart component doesn't provide the option to define the position of the tooltip when using crosshairs in the component.

Can you add a configuration option similar to categoryAxis.crosshair.tooltip.positionwhich is available in the jQuery suite?

Describe the bug
When we have an Input component that is used inside a Drawer, once the Input's text is selected, a JS error is thrown.

To Reproduce

1. Open this StackBlitz example
2. Click the "Magnifier" icon
3. Enter random text inside the Input
4. Select the text inside the Input

Expected behavior
The selection of the text inside the Input should not trigger any errors

Describe the bug
When configuring the Chart to have a Crosshairs the Tooltip that appears is not centered as it is in the other Kendo UI suites.

To Reproduce

1. Open this CodeSandbox example
2. Hover a randomly selected element in the Chart

Expected behavior
The Tooltip that appears above the vertical crosshair should be centered above the line

Screenshots

Describe the bug

After inserting an image using the "Insert Image" tool it is possible to add a hyperlink to it using the "Insert Hyperlink" tool.

If the image's dimensions are then edited by selecting the image and using the "Insert Image" tool, the hyperlink that was added no longer exists.

Before:

After:

To Reproduce

1. Open https://codesandbox.io/s/elegant-parm-l7w93g
2. Right click the image in the editor, you should see the option to open the link.
3. Select the image
4. Open the "Insert Image" tool
5. Change the width or height to another value (e.g. width -> 200px)
6. Click the insert button within the tool
7. Right click the image in the editor, you should see the option to open the link is no longer there.

Expected behaviour

The image should retain any hyperlinks that have been added even if it is resized.

The current implementation of the TileLayout component doesn't provide some details inside the reposition event that could be useful when working on more specific scenarios like swapping the position of two tiles without moving the others. 

If we know which is the dragged tile and its current position in the TileLayout's matrix + the current tile over which the dragged tile is currently positioned, through the reposition event, we can reorder the tiles the way we need them. 

The current implementation of the Native Menu component doesn't provide some configuration options that are available in the Kendo UI for Angular suite. 

Can you add the following configurations of the openOnClick property as it is available in the Angular suite? 

• "leave"—The items open on hover until either an item is selected, or the mouse pointer leaves the Menu and the predefined delay passes.
• "click"—The items open on hover but do not close when the mouse pointer leaves the Menu. To close the items and avoid opening the Menu on hover, the user has to click a random place on the page.

Describe the bug
In a scenario of a DropDownList with virtualization and a valuePrimitve set to true, the selected value disappears if the data in the popup is scrolled.

To Reproduce

1. Open this StackBlitz example
2. Open the popup of the DropDownList and select 'Item 5'
3. Open the DropDownList again and scroll the data down

Expected behavior
The selected value of the DropDownList should not disappear when scrolling its data.

Screenshots

If the Grid is initialized with no items, the first call to resetTableWidth as part of the initialization sets the width style on the k-grid-table to 0px.

If any items are added afterwards this style remains, even though the autogenerated columns have a greater width. This leads to the grid not being visible until its size is set manually.

Sample (Grid demo with column definitions removed and changed load the data after mount instead of after creation): https://codesandbox.io/s/late-hill-rkdhc5?file=/src/Grid.vue

When using both filtering and virtualized dropdownlist, it can sometimes occur that the list will show no items after a series of repro steps:

Stackblitz (modified with only a console.log in the handlePageChange function) from Vue Dropdowns Library & DropDownList Component - Virtualization - Kendo UI for Vue Docs & Demos (telerik.com)

Qsz3dh (forked) - StackBlitz

1. open dropdown
2. type 33333 into the filter
3. see no data found
4. quickly remove the last 2 3's, so now you're only filtering on 333
5. quickly scroll down, then quickly scroll up
6. see no data found and see that skip is NaN in the console

Describe the bug
Importing Kendo UI components results in our WebPack build producing the incorrect "dist" output.
Sometimes Webpack build adds additionalType.d.ts files and their directories to the dist folder
More information can be found in ticket:1602899

Add groupHeaderColumnTemplate, as in Kendo jQuery Grid and Kendo Vue Wrapper Grid, that can be applied as it is done in this demo https://demos.telerik.com/kendo-ui/grid/aggregates.
