switching off tooltips in general

Hello dhtmlx-Team,

is there any possibility of turning off tooltips in general?
Maybe in the same way I can write my own error handler with dhtmlxError.catchError(…)?

Thanks in advance!

Actually you can disable tooltips for necessary columns by
    grid.enableTooltips(“false,false,false,true,false”)

false - disable tooltips for related column
true - enable tooltips for related column

I get a kind of tooltip when I drag a row - it shows me the ID of the row and this follows the mouse.
Is there anyway this can be switched off?

This is a "drag marker"
You can redefine  rowToDragElement to change it appearance

mygrid.rowToDragElement=function(id){
    return “row ID=”+id;
}
