hi , i have 2 question about grid event.

2.the " onRowDblClicked" will fire 2 times on “onRowSelect”.the order is “onRowSelect” ,“onRowDblClicked” ,“onRowSelect”.

somebody help me ???

1.the event onRowIdChange is not work.

Unfortunately I was not able to reconstruct your issue. Calling the changeRowId() method triggers the onRowIdChange event successfully.
Please, note that the event is available in PRO version only:
https://docs.dhtmlx.com/api__dhtmlxgrid_onrowidchange_event.html
If the issue still occurs for you please, provide a complete demo, where the problem can be reconstructed locally.

2.the " onRowDblClicked" will fire 2 times on “onRowSelect”.the order is “onRowSelect” ,“onRowDblClicked” ,“onRowSelect”.

Unfortunately it is not available to prevent a second onRowSelect triggering during the row double click.
