To demonstrate:

1. Open your simplest interactivity/selection demo, which is not grouped, in StackBlitz. See: https://www.telerik.com/kendo-react-ui/components/grid/interactivity/selection/

2. Add the Grid's group prop. To demonstrate the bug nothing else needs changed

<Grid group={[]} ...

3. Run demo, scroll down and pick a row.

4. Observe the grid scrolls to the top and you cannot see your selected row unless you scroll back.

We use data grids with virtual scrolling for inline editing a large number of records. However, when we want to add a new row to the grid it automatically resets the scroll position and doesn't even fire onPageChange event so the records you see do not correspond to the scroll position.

Check the following example (scroll to bottom, click anywhere on the table - this will add a new row - and observe the described problem):

https://stackblitz.com/edit/react-52zzvz?file=app%2Fapp.tsx%3AL78

Currently (as visible in grid demos), touch drag scroll in mobile (responsive) mode is not working when rows selection is enabled.

There is no known workaround since the complexity of implementing custom row renderer with all the intricacies of the grid's behaviour would be a huge task.

The client's facing issue is that when using a KendoReact grid on mobile device, they can't easily scroll the grid rows data by touch drag scrolling the rows.

As a follow on to this bug:

Steps to reproduce:

• The "General Info" column has width setted to 500px

See Image 1.png

• resize it in the grid to make wider

See Image 2.png

• lock the "General Info" column
• scroll horizontaly

I am requesting a new feature so that "that the locked prop is passed by default to the child columns"

I think this would be a great feature to have out-of-the-box, and hopefully it's something easy to add from your end. UX-wise, it's really difficult to wrap your head around a non-alphabetized list, especially when the list is used for the special purpose of filtering -- you now have to filter down the list before you can filter the grid itself, which adds more overhead for the user.

I understand that Excel is not the end-all and be-all, but Excel also sorts it by default:

The GridHelper is defined in a separate file, and this is the way we can use it - https://www.telerik.com/kendo-react-ui/components/grid/getting-started/gridhelper/

However, I prefer if it is exported from the Grid package, and is maintained from there.

Add the ability to apply table breakpoints to the Grid for responsive behavior.

Similar to the Bootstrap tables:

https://getbootstrap.com/docs/4.4/content/tables/#breakpoint-specific

I have one column that contains mix of boolean and string values. When I attempt to apply a filter function to that column, it generates an error for the boolean value true because indexOf cannot be performed on a boolean. When I have other formats along with strings and I use filter="text", I would like the value to be converted to string in the filter function rather than modifying the data on my end before calling the filter function, because that would actually be incorrect data.

Example

https://www.telerik.com/kendo-react-ui/components/grid/filtering/

If I change

<Column field="Discontinued" width="190px" filter="boolean" /> 

to

<Column field="Discontinued" width="190px" />

and then search for anything in that filter it throws error.

Maybe if you make the `filter="text"` always convert the all the values to string values that would help resolve the error

It is important for my users to be able to invoke the GridColumnMenuFilter  directly from the grid header. ie. The jQuery version has the filter icon beside the header text  (Rather than having to click a menu and then click "Filter" - which is necessary if all I want is a filter.

I know this is possible with some CSS.  But it is important that there is a visual indicator that the filter is on (which the jQuery version supports but doesn't seem currently possible with the React version)

Thanks

Hi,

I would like to have 'isnullorempty' filter for text field on Data Grid. There are 'isnull' and 'isempty' filters but it is not straightforward for non-engineer guys. If we have 'isnullorempty' filter, I think it is very useful. 

Other option, is there any way to customize filter operator by myself so that we can have any filter operation?  

Thank you,

Tatsuro Matsumoto.

Similar to how you can specify a column for the selection, it'd be nice if you could specify a column for the expand / collapse column so that you can provide a header value and handle a header value click change event.

The idea being that I could mass expand or collapse master detail rows similar to how I can mass select rows.

In our project we control column widths manually as we have complex logic on how wide each column should be, based on a number of external criteria. However, those widths are not fixed and might change during the lifetime of the data grid.

This was not causing any problems up to version 5.11.0 but after we upgraded the Kendo packages this controlled behavior of the column widths broke:

kendo-react-grid v5.11.0 example (working):
https://codesandbox.io/s/crazy-bird-ss7mgl?file=/app/main.tsx

kendo-react-grid latest example (broken):
https://codesandbox.io/s/dazzling-antonelli-wxsflj?file=/app/main.tsx

If we inspect the elements of the data grid, we can see that there is an inline style attribute on the header and body tables, setting the total width of those <table> elements to the sum of its columns. However, that value is not updating after the initial mount as it was prior to v5.12.0 which effectively makes the column widths uncontrollable.
