Hi, I have a RadCalendar (ajax q2) that I am assigning different event descriptions via the Dayrender Event as shown below. The goal is to show a RadWindow that receives the EventID of the clicked day (eventID being something unique in our system). I have tried to do this by adding a .Attributes.Add onclick along with associated javascript as shown below. However, what happens when I click an Event is that the window initially opens but then closes after postback. All I want is for the window to stay open after postback. Any thoughts on how to achieve this? Many thanks.

// Javascript function (assumes rwm is a radwindow manager on page
function launchAgenda(EventID)
{
  var oWnd = $find("<%= rwmAgenda.ClientID %>");  
  oWnd.show();  
  oWnd.setSize(900,700);  
  oWnd.moveTo(10,10);
  oWnd.setUrl("Faculty/Agenda.aspx?EID=" + EventID);
}
</script>

' Visual Basic DayRender sub
  Public Sub CustomizeDay(ByVal sender As Object, ByVal e As Telerik.Web.UI.Calendar.DayRenderEventArgs) Handles RadCalendar1.DayRender
        Dim CurrentDate As DateTime = e.Day.Date
        Dim currentCell As TableCell = e.Cell
        Dim d As CalendarDay
        Dim c As TableCell
Dim EventID as Integer = 52
 
                    Dim EventDesc As String = "my event"
                    currentCell.Text = EventDesc
                    currentCell.Attributes.Add("onclick", "launchAgenda(" & EventID.ToString & ")")

    End Sub 'CustomizeDay

Hello Karl,

If you want to keep the window instance after it is opened for a particular cell open and initiating a postback request, you will need to find a way to re-invoke the launchAgenda(EventID) client method the response is received back from the server.  This strictly depends on your custom logic, that is why I am not able to provide a definite solution/code snippet for your case. Let me know if I am missing something.

Kind regards,
