Hello Tony,
First of all, congratulations for your job. The grid is a great tool.
Here's the thing.
obtenerValor(id),calculaTotal(id)–> id is the row, column id of the cell (1_ColumnName);
In IE, it just ignores those events. I hava a temporary solution which is this one, what do you think about it? Is it correct?
//check which browser, and bind change and focus events to all text on the grid
