Hello, I have the following example. The problem is that I select Germany (row 2) and then click on refresh, Germany is still selected but if I press shift to add another row to my selection (for example Belgium in row 4) the selection brokes and is selecting from row 1 until row 4. So my question is if there is a way to fix this kind of bug?
This is the code that I use:

Hello, Francisco,
Thank you for the provided Dojo.
The problem occurs because the focus of the last cell/row you selected is lost, once you refresh the Grid. If you wish to restore the focus, you can include the following logic the dataBound event.
if(itemsToSelect.length > 0) {
let lastRow = itemsToSelect[itemsToSelect.length - 1];
grid.selectable._lastActive = lastRow;
grid.current($(lastRow).find("td:first"));
}Updated Dojo:

Let me know if you have any questions.
Best Regards,
