Hi,

I can't get TimeSlotContextMenus to work, I get a script error saying that "'this._weekModels.0' is null or not an object".

    
              <Telerik:RadScheduler runat="server" ID="uxScheduler" 
        
                                    DataKeyField="ActivityID" DataEndField="EndDateTime" DataStartField="StartDateTime"   
        
                                    DataSubjectField="Description" HoursPanelTimeFormat="HH:mm" 
        
                                    DayHeaderDateFormat="yyyy-MM-dd" 
        
                                    FirstDayOfWeek="Monday" LastDayOfWeek="Friday" Height="100%" 
        
                                    SelectedView="DayView" ShowDateHeaders="false" ShowResourceHeaders="true" ShowHeader="false" 
        
                                    ShowFooter="true" MinutesPerRow="30" >             
        
                <MultiDayView UserSelectable="false" NumberOfDays="1" /> 
        
                <DayView UserSelectable="false" /> 
        
                <WeekView UserSelectable="false" /> 
        
                <MonthView UserSelectable="false" /> 
        
                <TimelineView UserSelectable="false" /> 
        
                <AppointmentTemplate> 
        
                  <IMSC:ActivityItem ID="uxActivityItem" runat="server" ActivityID='<%#Bind("ID") %>' /> 
        
                </AppointmentTemplate> 
        
                <AppointmentContextMenus> 
        
                  <Telerik:RadSchedulerContextMenu runat="server" ID="uxAppointmentMenu">  
        
                    <Items> 
        
                      <Telerik:RadMenuItem runat="server" Text="Open/Edit" value="edit" /> 
        
                      <Telerik:RadMenuItem runat="server" IsSeparator="true" /> 
        
                      <Telerik:RadMenuItem runat="server" Text="Delete" Value="delete" /> 
        
                      <Telerik:RadMenuItem runat="server" IsSeparator="true" /> 
        
                      <Telerik:RadMenuItem runat="server" Text="Cut" Value="cut" /> 
        
                      <Telerik:RadMenuItem runat="server" Text="Copy" Value="copy" /> 
        
                    </Items> 
        
                  </Telerik:RadSchedulerContextMenu> 
        
                </AppointmentContextMenus> 
        
                <TimeSlotContextMenus> 
        
                  <Telerik:RadSchedulerContextMenu runat="server" ID="uxTimeSlotMenu">  
        
                    <Items> 
        
                      <Telerik:RadMenuItem runat="server" Text="Create Activity" Value="create" /> 
        
                      <Telerik:RadMenuItem runat="server" IsSeparator="true" /> 
        
                      <Telerik:RadMenuItem runat="server" Text="Paste" Value="paste" /> 
        
                    </Items> 
        
                  </Telerik:RadSchedulerContextMenu> 
        
                </TimeSlotContextMenus> 
        
              </Telerik:RadScheduler>

What I'm doing is keeping the Schedular in DayView and create resources for each date I actually want to show, this is so that it can display dates for non-consecutive days. I don't know if this has something to do with it, but the context menu for a time slot is not coming up. This has totally halted my project and I need to get this fixed.

Hi Joacim,

I tested your code, but there was no problem at my end. Please, check the attached sample.

Thank you for your reply Peter. I just found the reason for the error, even though I'm totally baffled why it would cause an error, When I define my resources I used the following code:

    
              Private Sub InitilizeResources()  
        
                Dim resourceType As New ResourceType("DateString")  
        
                resourceType.ForeignKeyField = "DateString" 
        
                uxScheduler.ResourceTypes.Add(resourceType)  
        
                uxScheduler.GroupBy = "DateString" 
        
                uxScheduler.SelectedDate = New DateTime(2000, 1, 1)  
        
              End Sub

Appearantly setting the ForeignKeyField to a property named "DateString" caused the error, the error occured because the property started with the word "Date". You can imagine that finding this bug was not an easy task.
