Open radwindow on double click of Radgrid cell.

[Soumya]

I need to implement a particular scenario as given below.

I have a radgrid with one column say,Time has values in all rows,starting from 8 am to 8pm.Other columns in the grid may/may not have values in all rows.Basically I am trying to develop a radgrid to show all the appointments for a particular day.If an appointments exist for a particular time slot,then details of the appointment(name,appointment no,mobile no etc) will be displayed in the rest of columns of that row.
For other time slots with no appointments,rest of the columns will be empty for that time slot.
I thought of doing this with a radgrid instead of radscheduler,as I am not sure is If I can accomplish all these with a Scheduler.Grid is filtered by a calendar and multicolumn combobox value.

Now my issue here is:
I need to double click on a cell,which has no appointment .On double clicking ,need to open a radwindow,in which I will save an appointment,which will be displayed in the radgrid on closing.
I could see only OnColumnDblClick,OnCellSelected,OnRowDblClick as client side events.How to open a rad window with below two conditions
1)On double click of a cell
2)If that particular row has no appointment,(row will surely have value in the time column),radwindow should not open on double click.
3)As I mentioned above grid is being filtered by a multicolumn combobox.Grid has columns Time,duration,name,contact number.
When user double click on a grid celI,I need to pass multicolumn combobox value(which is placed outside grid),Time & duration of that particular row in grid(row corresponds to the clicked cell) as parameter to the radwindow.

Please help m on this.
Thanks,
Soumya
