how to get rowindex of the cell that trigger this clientside function

[Weilun]

Is there anyway to get rowindex of the cell that trigger this function.
I know there is a way which uses OnRowClick or OnRowSelect.
In my case i dont want the user to selectrow to update the cell.

This there anyway to change the 4 into rowindex

function editQuantity(sender, eventArgs) {
    var masterTable = $find("<%= CartRadGrid.ClientID %>").get_masterTableView();
        masterTable.updateItem(4);
}

This is my radgrid

Hello,

One suggestion is you can access the RadNumericTextBox from server side and pass the index as shown below.
C#:

protected void grid_ItemDataBound(object sender, GridItemEventArgs e)
{
 if (e.Item is GridDataItem)
 {
   GridDataItem item = (GridDataItem)e.Item;
   RadNumericTextBox txt = (RadNumericTextBox)item.FindControl("RadNumericTextBox1");
   int index = e.Item.ItemIndex;
   txt.ClientEvents.OnValueChanged= "function (sender,args){rowIndex('" + index + "');}";
 }
}

JS:

function rowIndex(index)
{
 alert(index);
}

Thanks,
Princy.
