This method returns the value or contents of a grid cell. The cell must be visible when this method is called.
When using a database-driven grid with the "load fields into widgets" property enabled, getDataValue() will need to be used instead, as the data is not longer loaded directly onto the grid.
- row - the row number to retrieve the value from; when using events such as onrowclick, onrowdblclick, onrowmouseover, and onrowmouseout, the row variable is automatically passed into the event and can be used as the parameter to this method; row numbers start with row 1
- col - the column number to retrieve the value from; the column numbers are zero-based (i.e. the first column* is column 0, the second column is column 1, etc.)
