    Default Getting cell value using onCellUpdated and the JSONDataModel

    Getting cell value using onCellUpdated and the JSONDataModel


    I am using a JSON data model for my grid and I added a listener for the onCellUpdated event. I tried to get the value of the grid during the onCellUpdated event but I keep getting a null value.

    Here is my onCellUpdated code:
    Code:
    function onCellUpdated(grid, rowIndex, colIndex, e){
        alert('Cell at row ' + rowIndex + ', column ' + colIndex + ' was clicked!  New value=' + grid.dataModel.getValueAt(rowIndex,colIndex));
    }
    What am I doing wrong?

    The data model onCellUpdated includes the data model, not the grid:

    Code:
    function onCellUpdated(grid, rowIndex, colIndex, e){
        alert('Cell at row ' + rowIndex + ', column ' + colIndex + ' was clicked!  New value=' + 
                            grid.dataModel.getValueAt(rowIndex,colIndex));
    }
    should be:

    Code:
    function onCellUpdated(dataModel, rowIndex, colIndex, e){
        alert('Cell at row ' + rowIndex + ', column ' + colIndex + ' was clicked!  New value=' + 
                             dataModel.getValueAt(rowIndex,colIndex));
    }
    The afteredit event on the grid will be the same, except with a grid as the first parameter.
