Describe the bug
If you try to group the data in a Grid by a column that has a value of "null", the browser hangs, and an error appears in the console.

To Reproduce

1. Open this StackBlitz example
2. Group the Grid by "Unit Price" field

Expected behavior
The data should be grouped according to the values inside the UnitPrice column. A column with an empty header should appear for the group with a "null" value.

Screenshots

Workaround

Convert the "null" values to empty string with a code like this:
this.products.forEach((o) => { o.UnitPrice = o.UnitPrice === null ? '' : o.UnitPrice; });
Here is a modified example in which the above code is added to the getData method.

Describe the bug
The selectionChange & headerselectionchange events of the Native Grid component are unexpectedly triggered when filtering data in the component.

• The issue is not replicable on Chrome and Safari.

• A possible workaround for the bug is demonstrated in this StackBlitz example

To Reproduce

1. Open this StackBlitz project in Firefox
2. Enter random text in the filter input of some of the fields
3. See the following two errors in the console:

and

Expected behavior
No JS errors should appear when filtering the Grid component, no matter the browser that is used.

There is an issue with white space that appears when you scroll a Grid with Groupable and Virtualization configurations switched on.
Reproduction:

1. Go to this article.
2. Scroll the Grid till the end of the scroller
3. See the white space.

Jumping issue:
When you scroll the linked above example there is a strange "jumping" of the rows.

• Bug report

Current behavior

https://stackblitz.com/edit/tynxxg-vckenw?file=src/main.vue

1. With the default code in the example, when first scrolling the skip is not accurate. If the grid is scrolled extremely slowly, you can see the skip is not incremented at first. If scrolling quickly, it is very jumpy.

2. The faster you attempt to scroll, the stranger the skip behavior becomes unlike with simply removing the grouping grid prop in the same example. I've been able to get into situations it in the provided StackBlitz by scrolling down and scrolling back up quickly where it hangs on row counts and where it will scroll past the 0 indexed row causing an empty grid, then scrolling down again with either jump with a large skip number or sometimes throw an error.

3. Possibly provide more flexibility to the scenario

Expected behavior

skip and cache are working correctly

Hello Team.

I appreciate grid's reorderable function work at Nuxt3(@kendo-vue-grid: 3.14.2).

But For some reason, this function doesn't work properly. so I report a bug.

I reproduce a stackblitz code.
https://stackblitz.com/edit/nuxt-starter-gmag5m

I implemented it like this,

After fetching(=GET) column data from the server, reorder the columns using kendo grid's reorderable function and save(=POST) it on the server.

I call columnExecute function, so server refetch(=GET) column data.

at /pages/index.vue, colums ref change rightly.

at /components/grid.vue, columnList ref change rightly.

But rendered kendo grid's column doesn't change.


please check this issue. 

Sincerely,
Eunbyul.

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
When using a slot template inside the Grid, the content of the template should always have only one DOM element on the root level. If there are multiple elements on the root level, only the first element will be rendered.

In scenarios when we add a comment inside the slot template as a first element, the Grid recognizes it as the first element in the template and nothing will be rendered.

To Reproduce

1. Open this StackBlitz example
2. See the Unit Price column

Expected behavior
The rendering of the slot template shouldn't depend on the number of root elements inside it. The template should be rendered in scenarios with both single and multiple elements in the root.

Screenshots

The column virtualization functionality doesn't work when the Grid is configured to work in RTL direction.

To Reproduce

1. Open this StackBlitz example
2. No data is visualized inside the Grid
3. If we remove the :dir="'rtl'" configuration the Grid data is correctly displayed

Expected behavior
The Grid's column virtualization should work with both LTR and RTL configurations.

Describe the bug

When exporting the Kendo UI for Vue Native Grid data to a PDF file and the paper-size property is set to true, if there are locked columns inside the Grid, these columns are exported as empty columns.

• Workaround - a possible workaround is demonstrated in this StackBlitz example

To Reproduce

1. Open this StackBlitz example
2. Press the button above the Grid and save the exported file
3. Open the saved file and see how the locked columns have been exported

Expected behavior
All Grid columns should be correctly visualized in the exported PDF file, no matter if they are locked or unlocked.

Screenshots

Additional context
If we set the paper-size to a pre-defined value like 'A4', the issue is not replicable

When defining a footer in a locked native Grid column, the footer of the column is moving when the content of the Grid is scrolled horizontally.

To Reproduce

1. Open this CodeSandbox example
2. Scroll the content of the Grid to the right

Expected behavior
The footer inside the ID column should not move when scrolling the Grid's content

Screenshots

Describe the bug
There is a blank space at the bottom of the Grid when the user scrolls the data. This blank space appears on a specific configuration where the Native Grid is configured with virtual scrolling and the groupable property is set as follows:

:groupable="{ footer: 'visible' }"

• The issue is replicable in both Vue 2 and Vue 3
• The issue is not replicable if the groupable prop is defined like this:

:groupable="true"

To Reproduce

1. Open this StackBlitz example
2. Scroll the data items to the bottom of the Grid

Expected behavior
There shouldn't be any white/blank spaces at the bottom of the Grid

With this error:

To Reproduce

1. Open this project
2. Run 'npm install'
3. Run 'npm run test:unit'

Expected behavior
The test should pass as it used to pass in version 3.5.0, for example.

Describe the bug
When activating the keyboard navigation inside the Native Grid and there are custom cells in this Grid, the navigation between the cells(in a specific scenario) is slow.

Scenario: In a Grid whose cells are all custom, focus a random cell in the first column. Then press and hold the right keyboard arrow. The focused cell starts moving to the right and then freezes until the last Grid column is reached.

Here is a video demonstrating the described scenario: https://user-images.githubusercontent.com/41293735/202707680-1964d01e-dbd3-4a35-93c4-1dbcfd45e887.mp4
