Current behavior

When there is a custom cell template applied to a column in the Grid(Native), using the grouping functionality breaks Grid's layout

Expected behavior

The Grid's layout shouldn't be affected if we apply a custom cell template

Minimal reproduction of the problem with instructions

1. Open this StackBlitz project
2. See that the values in the ProductName column are bolded, but Grid's layout is broken
3. Remove the cell template definition on line 54 by removing the cell property.
4. Run the project again and see how if we don't apply a cell template, Grid's layout is being displayed correctly

Goodmorning Progress,

We're working quite some time with Kendo for Vue and we are slowly migrating some old 'wrapper' grids to the new native grids. We know there are some limitations in it, because not everything is developed yet, but that wasn't a show stopper for us.

Or project uses quite a lot of data (like a google sheet) and we need it to be editable. So we implemented a native grid and a custom cell render with a VueComponent. This works perfect in case of a little amount of cells, but when there are more rows and columns it's giving us some performance issues.

First we tried virtual scrolling, but this feel 'honky-bonky' and is not even workable on a mac. Then we tried column-virtualization to minimize the rendered data, but also that didn't work. Columns aren't re-rendered when visible and its conflicting with our three locked start columns (visually data overlapping, numbers go through each other, etc).

Then our options are down to zero, so i started to investigate with some performance profiling what's happening. In our case we have 70 columns and 500 rows, this results in like 35k cells. Rendering isn't the big issue, until u start interact with the grid. Our RowClick-function sets one item in the data-items to 'inEdit' like the docs also showing. When this is happening the page freezes and i start wondering why. I found out that ALL the GridCell's (with a custom CellRender) are calling the updateRender-function. So 35k functions are called in some milliseconds and causes it to freeze. It takes around 30 sec's to get it a bit reactive, but you can understand its not workable anymore.

Our wrapper grids hadn't a single problem with handling these kids of data (no paging, no weird stuff, also custom renders for every cell)

Can you please provide me an answer why this is happening? It's possible to get access to our test-environment with the grids in action to visualize my problem a bit better. 

We have a payed license on a co-worker account (berend.haan@..).

Kind regards, 
Sander

The pagination on the jquery grid is responsive by default with the ability to turn off responsiveness if desired. https://docs.telerik.com/kendo-ui/api/javascript/ui/grid/configuration/pageable.responsive

It would be useful to add responsiveness to the pagination on the Vue Native Grid with the same ability to turn it off if desired.

The Accessibility Support page for Kendo UI for Vue Native Components (https://www.telerik.com/kendo-vue-ui/components/accessibility/accessibility-compliance/) incorrectly implies that the Vue Native grid has keyboard navigation support. The page seems to be referring to native components as seen by the breadcrumb and the introduction text.

All of the items in the list except for the grid are linked to the Vue Native component. The "grid" item is linked to the Vue Grid Wrapper (https://www.telerik.com/kendo-vue-ui/components/grid-wrapper/keyboard-navigation/).

I believe there's already a (unplanned) feature request out there to add keyboard navigation features to the native grid, but in the meantime, please remove the grid from this page as it does not currently support full keyboard navigation.

Currently in the Vue Native grid, you can only specify column widths in pixels.

This becomes problematic if the user has their browser font size set to a larger size. Since our font size, padding, etc. are using responsive rem units for sizing, they properly resize to a larger size, but since the column widths are set in pixels, the now larger filter fields and buttons don't fit appropriately in the alloted space (see below screenshot). For smaller columns, you can't even see what you've typed into the filter field.

In the screenshot, the larger font size was set in Google Chrome by going to Settings > Appearance > Font size > Very Large.

This enhancement would be helpful to ensure improved accessibility for those who need a larger font size in order to read the text.

It will be very helpful if there is an example that demonstrates how we can copy and paste data from Excel to Kendo UI for Vue Native Grid.

Current behavior

If the scrollable property of the Grid is set to 'null' the header of the Grid changes its background styles a column width, compared to when the property is not set.

Expected behavior

The styles of the Grid should not be changed when the scrollable property is defined.

Minimal reproduction of the problem with instructions

1. Open this StackBlitz example.
2. Remove the :scrollable="'none'" property definition from the Grid and see how it changes

Add functionality that allows the users to configure the Native Grid's Pager in a way it has the "All" option in its page sizes DropDownList.

The "All" option is available in the Kendo UI for jQuery suite(check the second example on the page). When the "all" option is selected, all Grid records are loaded on one page.

If a date column has a GridColumnMenuFilter, the filter drop down closes as soon as you attempt to open the date. 

Reproduction steps:

Add a GridColumnMenuFilter to a column that is defined as a date.  Upon opening the filter and attempting to select a date, the filter immediately closes.  

This example has the problem reproduced. https://stackblitz.com/edit/zdmtjk?

Describe the bug
The layout of the column menu popup window, inside the Native Grid, is different when using version 4.x.x and version 5.x.x. of the Kendo Themes.

• The issue is replicable with all Kendo Themes

To Reproduce

1. Open this example
2. Click on the column menu of the Name column
3. Inside the column menu, click on "filter"

Expected behavior
There should be a space between the different elements in the column menu -> filter popup

Screenshots

Describe the bug
When having a scenario of Native Grid with a paging functionality, the pageChange event is being triggered when there is an interaction with the UI of the Pager.

When the user selects the number of rows per page, by choosing this value from a DropDownList, the object available in the event handler of the pageChange event has a value for its event property.

When the pageChange event is triggered by a change in the pages (1, 2, 3, etc.) the mentioned above event property has a value of undefined inside the event handler.

To Reproduce

1. Open this StackBlitz example
2. Change the number of items per page to 20.
3. Change the Grid page by using the page numbers
4. Check the browser's console

Expected behavior
The event prop should be defined no matter which element is triggering the pageChange event.

Currently, the Native Grid Columns have the minResizableWidth property available in the API,

Can you provide a maxResizableWidth property that will do the same thing for the Grid's width but will limit its maximum width? 

In the jQuery version of the Grid, the columnMenu can be configured to show/hide the different column menu options.

Here is an example of how the sortable prop can be configured in a way the sorting options will be hidden in the column menu. 

Please provide the same configurations options for the column menu in the Native Grid

Describe the bug
When the Grid's resizable property is set to true, the following test fails:

import { describe, it, expect } from "vitest";
import App from "../App.vue";
import { render } from "@testing-library/vue";

describe("App.vue", () => {
  it("renders apps", async () => {
    render(App);
  });
});

• The issue is not replicable if in Draggable.js file the:

import KendoDraggable from '@progress/kendo-draggable';

is changed with:

import { Draggable as KendoDraggable } from '@progress/kendo-draggable';

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.

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.

Providing an Excel-like behavior inside the Native Grid will be a very nice feature for the component. The described behavior includes:

• Cells and rows selection like in Excel
• Editing like in Excel
• Keyboard navigation like in Excel
