Hi Megan,

Currently, the feature regarding allowing range selection with the Shift key when using the checkbox selection functionality is not part of our immediate development plans in the roadmap and the customer demand for this feature is still being monitored:

• https://www.telerik.com/support/whats-new/kendo-angular-ui/roadmap 

On that note, I would recommend following the current item in order to stay updated on the progress of the future implementation of this enhancement.

In the meantime, an available approach for achieving this functionality is by creating a custom checkbox column via the CellTemplateDirective and the SelectionCheckboxDirective of the Grid. In that way, the developer will have full control over the click event of the checkboxes, the currently selected row index, and the data item associated with this row:

• https://www.telerik.com/kendo-angular-ui/components/grid/columns/templates/#toc-cell-template 

Then, a custom logic can be implemented that will handle the Shift + click event on a specific checkbox and adjust the selected items accordingly in the selectedKeys collection:

With the above being said, in case this feature is crucial for your project, I would also like to present you with an offering that may be relevant and applicable to your needs - our Feature Acceleration program. This program fits well in scenarios where a feature or enhancement is important for an application's success, but it is not planned to be available at the time of its completion.

In this line of thought, please let me know if you are interested in pursuing this option and I will put you in touch with our Professional Services team.

Regards,
Zornitsa
