when i insert the value through grid then this code is O.K

BUT at the time of the updation this code give the error

like _childindex is null or not and object when i use the code

mygrid.cellByIndex(i,0).setValue(myvalue);

then object is not suppored

if(counter<=0)
{

var rowid=mygrid.getRowIndex(mygrid.getSelectedId());
alert('row id='+rowid);
// alert(mygrid.rowsCol.length);
// var myvalue=mygrid.cells(4,5).getValue();
var myvalue=mygrid.cells(mygrid.getSelectedId(),5).getValue();
alert('myvlue....'+mygrid.getRowsNum());

for(var i=rowid+1;i<mygrid.rowsCol.length;i++)
{
alert('inside');
//mygrid.cells(mygrid.getRowId(i),5).setValue((mygrid.getSelectedRowId(),5).getValue());
mygrid.cells(i+1,5).setValue(myvalue);
mygrid.cells(i+1,6).setValue('');
mygrid.cells(i+1,7).setValue('');

}
counter=counter+1;

}

>>like _childindex is null or not and object when i use the code
Such error occurs when you are using command with non-existing rowID or rowIndex ( your case ) 


There are two command in grids
   grid.cells(rowId, cellIndex)
   grid.cells2(rowIndex, cellIndex)

according to your code you are using rowIndex  ( var rowid=mygrid.getRowIndex ) but using grid.cells, which require rowID as incoming parameter.
