Hi there

I am trying to keep track of modified rows of the WebDataGrid. The following discussion http://ko.infragistics.com/community/forums/t/67651.aspx implies that IsDirty() method of GridRecord is not going to work. So to keep track of the modified values I have added a hidden data bound column to the grid – bound to ‘Status’ property of the record and implemented EditingClientEvents-CellValueChanging event handler on the client side. The event handler sets a value in the hidden column. On the server side, when a "Save" button is pressed on a form, I iterate trough the WebDataGrid rows, check the value of the ‘Status’ property and save the records that are added or modified.

The event handler for  CellValueChanging looks like this:

function updateEntityState_OnChange(sender, eventArgs) {

     for (i = 0; i < eventArgs._cell._row._element.cells.length; i++)

    {

        if (sender._columns._items[i]._key == 'Status') {           

             var status = eventArgs._cell._row._element.cells[i].firstChild.nodeValue;

             if (status == null) {

                eventArgs._cell._row._element.cells[i].firstChild.nodeValue = 2/*Added*/;

            }

            else if (status == 0/*Unchanged*/) {

                eventArgs._cell._row._element.cells[i].firstChild.nodeValue = 1/*Modified*/;

            }

            break;

        }

    }

}

The implementation above does not work. When I step though the code in the debugger everything looks fine but the when I check the row on a server a value in “Status” column is always 0.

 I have three questions here:

1. What is a correct way of setting value of another cell from client side code?
2. The use of underscored methods/properties in my code does not look right. When I tried to use more ‘civilized’ function call notation, (similar to http://ko.infragistics.com/community/forums/t/44515.aspx) I am getting Object does not implement method errors. Am I missing some Infgagistics library/script that have cell.get_value() and cell.set_value() defined?
3. Is there any way of making use of IsDirty() method of GridRecord object on a server side?

Thank you
