Attributes.Add for client onclick event

[Jon]

Hi All,

I'm using the scheduler to display two different types of calendar data although it comes from one stored procedure and is merged there.  I want to be able to have the user click on an appointment and then the relevant screen be displayed for that appointment type.

I am trying to use Attributes.Add to add a javascript call to one of two functions (with the relevant ID for the task).  The javascript will then open a window with the correct page in it.  The following is some abbreviated code that I cannot get to work, the scheduler itself works fine but not the click event.

Private Sub uxRadScheduler_AppointmentDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.SchedulerEventArgs) Handles uxRadScheduler.AppointmentDataBound
    Dim dataRowView As System.Data.DataRowView = CType(e.Appointment.DataItem, System.Data.DataRowView)
    If dataRowView.Item("LeaveID") IsNot System.DBNull.Value Then
        e.Appointment.Attributes.Add("onclick", "javascript:ViewLeave('" & dataRowView.Item("LeaveID").ToString() & "');")
    Else
        e.Appointment.Attributes.Add("onclick", "javascript:ViewTask('" & dataRowView.Item("TaskID").ToString() & "');")
    End If
End Sub

Any pointers?

Regards,

Jon

Hello Jon,

I suggest you better handle OnClientAppointmentClick and use custom attributes to pass any additional info for the appointment. Here is an example:

<script type="text/javascript">
       function OnClientAppointmentClick(sender, eventArgs) {

           alert(eventArgs.get_appointment().get_attributes().getAttribute("TaskID"));

       }
   </script>

   <telerik:RadScheduler
       ID="RadScheduler1"
       runat="server"
       CustomAttributeNames="TaskID"

"TaskID" should be a column name or field in your RadScheduler's data source.

Many thanks Peter for the amazingly quick response!

It works a treat,  I'd not seen the CustomAttributeNames flag but with that it's easy.

Best Regards,

Jon
