Set the backgroundcolor of the grid at the loading time of the grid when the cell of 9th or 10 th is blank that cell color is RED
thank you
can be done as
mygrid.attachEvent(“onRowCreated”,function(id){
if (mygrid.cells(id,8).getValue()=="") ; //indexes start from 0
mygrid.setCellTextStyle(id,8,“background-color:red;”);
if (mygrid.cells(id,9).getValue()=="") ;
mygrid.setCellTextStyle(id,9,“background-color:red;”);
return true;
})
