Hi,

Using version 12.1 (3.12.1.2023), I have an MVC view which has a grid which needs to have all rows ticked and selected when the view loads.

I have been trying to use the selectRow method of igGridSelection for each row - the selection is shown correctly but the checkboxes are not ticked. Furthermore, the selectedRows method is bringing back an array where each row's index is NaN. 

If I then click a checkbox, the checkbox will be ticked but the selectedRows array will increase by one, this time with the correct index value. This is especially strange since I now have 7 items in selectedRows array from a grid with 6 rows.

It seems that the number of selected rows increases with every new tick. However, when you click on somewhere else on the row, the selectedRows array and the selection appearance appear to be completely fine.

Is there something that I can do to fix this or is this a bug?

I have attached the code for a simplified sample which I have been using to try to debug the problem.

Thanks for any help with this.

Si
