un-representable DateTime

[David]

I have events with no time.  My raw data looks like this:

Start =   2009-04-29 00:00:00.000
End  =   2009-04-29 00:00:00.000

When i try to load the calendar and bind I get the following error:
The added or subtracted value results in an un-representable DateTime. Parameter name: value

               <telerik:RadScheduler runat="server" ID="RadScheduler1" SelectedView="DayView" TimelineView-ShowInsertArea="true"
                    StartInsertingInAdvancedForm="true" Skin="WebBlue" Width="750px" Height="650px"

Hello David,

The problem is that you've set DayStartTime and DayEndTime to 00:00. Leave them at the default values and set ShowFullTime="true". The appointments should still show fine.

I hope this helps.

All the best,

It's always the littlest things you spend the most time on.  Ha.

That did the trick.  And I have also got the "All Day" row showing.

Working Sample here if my oversight can help:

<telerik:RadScheduler runat="server" ID="RadScheduler1" SelectedView="DayView" TimelineView-ShowInsertArea="true"
                    StartInsertingInAdvancedForm="true"  Width="750px" Height="650px" ShowAllDayRow = "true"
                    TimeZoneOffset="00:00:00"   DataSourceID="AppointmentsDataSource" DataKeyField="TaskKeyID"
                    DataSubjectField="TaskComment" DataStartField="StartDate" DataEndField="EndDate"
                    HoursPanelTimeFormat="htt" OnFormCreated="RadScheduler1_FormCreated"
                    ValidationGroup="RadScheduler1">

Thank You for great support !
