Kendo grid doesn't have in-built functionality to prevent row selection based on some condition.
One way is to remove css class "k-state-selected".
But i think there should be something like "changing" event which will be called before "change" event.
In that event developer write code and can cancel "change" event.
Or 
Boolean property something like "enabled" at row level (or cell level for cell selection) .

Hello team,

I noticed a bug with Kendo Grid since the 2023 R2 release, including the SP1 and SP2. Navigation with TAB isn't working as it should be, like in 2023 R1.

You can see an example here if you switch between the libraries : https://dojo.telerik.com/aBAJEteY

When being on a cell and pressing TAB, we should move to the next cell in edit mode, but in the last versions of 2023 R2, 1 cell of out 2 enters the edit mode. If we even look closely, we see that the cell actually enters the edit mode but it leaves it very quickly.

It happens to me on Firefox

Hope this is a bug and not feature.

It would be nice to be able to configure the grid in a way that when I collapse a group, the lines it was occupying are then filled up by the results from the following pages.

Kendo Grid currently only minimizes the results of the current page. It ignores the pageSize config we have set, not bringing more items to occupy the number of lines we have configured.

Here are some screenshots I took from the DevExpress grid. There you can see that the column year is grouped and initially the years 90 and 91 are expanded. When I collapse the year 90, the results from the year 91 fill up the space the other group was not using anymore.

Hi Team,

I would like to request to disable the AutoComplete functionality for string columns when the Filterable mode is set to row or menu, row.  This would help prevent extra Read calls for the string filters.  

Thank you!

Additional notes:

This functionality is showcased in the following KB article:

https://docs.telerik.com/kendo-ui/knowledge-base/grid-filter-multi-checkboxes-external-datasource 

I'd like to request it as a built-in feature in the Grid.

Hi Team,

I would like to request a way to utilize multiple edit modes for the Kendo UI Grid.  For example, configure updating the Grid with inline editing, but when creating a record, use popup editing. 

Thank you!

Currently, when the draggable column is also set to locked the rows cannot be reordered. -  Dojo - https://dojo.telerik.com/@NeliKondova/ErOlEgUP

I would like to be able to reorder the rows in the Grid when the draggable columns to locked.

3. Open the ColumnMenu of a Column
4. Quickly move your mouse through the Columns and Filter popups

Hi Guys,

Have just tripped over another regression in the 2023.1.314 release whereby resizing of a locked column also effects the sizing of any prior columns.

Reproduction of the problem

    Open the Grid Frozen Column Demo
    Decrease the size of the 'Ship Name' column

Current behaviour

As the width of column header decreases you hit a point where the width of the related data cells stop decreasing but the width of the data cells in previous columns start to decrease causing column misalignment. See attached screenshot.

Expected behaviour

Only the selected column should resize and previous columns should remain fixed.

Regards
Alan

Hello, 

I am no longer able to change grouped columns in their position. This bug seems to have arisen with the version Kendo UI 2022 R1. I have created a gif and a dojo for you. Dojo Also, as you can see in the gif and dojo, the "group" event is not fired on a reorder. 

Thanks.
