I can't seem to find a consistent way to get information from the currently selected row.  The code I see in the demo, and being used here in the forums is:

var id = e.row.cells[#].innerHTML;


But that simply doesn't fly when you're using a groupable grid.  As soon as you group any columns, the indexes start moving around.  I'd much rather see something like:  

var id = e.dataItem.ID; 

Any suggestions?

Hello Jeff Sheldon,

Since the dataItem is currently available only in the rowDataBound event I can suggest the following:

var id = e.row.cells[grid.groups.length + cellIndex].innerHTML;

If you are using editing you can use the following JavaScript function:

var dataItem = grid.dataItem($(e.row));

We will make it always available (not just when editing is enabled) in the next release.

Atanas, could you please to help with code to color by condition a row in nested view (master/detail grid) ?
I got undefined for e.row 
This is a bound function for nested grid

 function project_OnDataBound(e) {
            var grid = $(this).data('tGrid');
            $.each(grid.data, function (i, val) {
                var probability = grid.data[i].Probability;
                if (probability <= 50) {
                    e.row.style.color = "red";
                }
                if (probability > 50 && probability <= 80) {
                    e.row.style.color = "yellow";
                }
                if (probability > 80 && probability <= 99) {
                    e.row.style.color = "lightgreen";
                }
            });
        }

Hi Timo,

 DataItem is not available in OnRowSelect and probably will never be available. You can use the dataItem function to retrieve the dataItem associated with a particular row at any moment:

function onRowSelect(e) {
    var grid = $(this).data('tGrid');
    var dataItem = grid.dataItem(e.row);
}

Hello,

it works for AjaxBinding. Is there a way to do this with ServerBinding?

Hello Timo,

JavaScript DataItem is not available in server binding. You can use a hidden column instead.

Hello Rafael,

 Perhaps you are using the wrong event. You should use OnRowDataBound instead of OnDataBound.

I am locking this forum thread as it digressed from the original question.
