Grid - Multi row selection - onSelectedRowsChanged() - Negative index

Hello,
The index passed in parameters of onSelectedRowsChanged() is -1 the first time you select a line, if you simultaneously press the CTRL button.
I can imagine this is a bug.
Cheers

I cannot reproduce this, are you sure?

Dear Alex,
The mistake was in my code :-(
I apologize, before bother you I should have confirmed this with your sample (multi row.htm).
Best regards
