I did not get FirstVisibleTime property in view definition. But there is one with RadscheduleView. But when i am setting FirstVisibleTime property of RadScheduleView it is giving me exception. I am using Q2 2011 controls.

<telerik:RadScheduleView Style="{StaticResource RadScheduleViewStyle1}" x:Name="calendarView" ActiveViewDefinitionIndex="2"

AllowDrop="False" AutomationProperties.AutomationId="OWS_Results_Calendar_SchedulerView" ShowDialog="calendarView_ShowDialog"

AppointmentSelectionChanged="calendarView_AppointmentSelectionChanged" FirstVisibleTime="08:00" >

<telerik:RadScheduleView.ViewDefinitions >

<telerik:DayViewDefinition MajorTickLength="1h" MinorTickLength="30min" MaxTimeRulerExtent="700" MinTimeRulerExtent="700" />

<telerik:WeekViewDefinition MajorTickLength="1h" MinorTickLength="30min" MaxTimeRulerExtent="700" MinTimeRulerExtent="700" />

<telerik:MonthViewDefinition VisibleDays="30" FirstDayOfWeek="Monday" />

</telerik:RadScheduleView.ViewDefinitions>

<telerik:RadScheduleView.DragDropBehavior>

<local:CalendarDragDropBehavior></local:CalendarDragDropBehavior>

Hi Pooja,

I've tested the FirstVisibleTime property and it works as expected at our side. Please note that the view is scrolled to the set time only when there is not enough space, I've attached a short video to demonstrate how it works.

Best wishes,

FirstVisibleTime is not working for me as well. There was a run-time error. After I downloaded 01549RadControls_for_Silverlight4_2011_2_0927_TRIAL_hotfix today. No run-time error now. But the starting time is still 12: 00 am. Nothing changed.
Thanks

public MainPage(int committeeID)

{

InitializeComponent();

_vm = new MeetingsViewModel(committeeID);

this.DataContext = _vm;

radScheduleView1.FirstVisibleTime = new TimeSpan(7, 0, 0);

}

<telerik:RadBusyIndicator IsBusy="{Binding IsLoading}">

<telerik:RadScheduleView HorizontalAlignment="Left"

Hi Yana:
It did work running your sample. I found why my code did not work

<Grid x:Name="LayoutRoot" Background="White">

<telerik:RadBusyIndicator IsBusy="{Binding IsLoading}">

<telerik:RadScheduleView HorizontalAlignment="Left"

AppointmentsSource="{Binding Meetings}"

Name="radScheduleView1" >

<telerik:RadScheduleView.ViewDefinitions>

<telerik:DayViewDefinition MajorTickLength="1h" MinorTickLength="30min"/>

</telerik:RadScheduleView.ViewDefinitions>

</telerik:RadScheduleView>

</telerik:RadBusyIndicator>

</Grid>

Obviously it was caused by "RadBusyIndicator ". After I remove it, my code starts to work. But Why? Can your guys research it?

Thanks
Wei

Yana:
My silverlight testing project does not load any data. You know what, I tested your sample project by added RadBusyIndicator tag

<telerik:RadBusyIndicator IsBusy="{Binding IsLoading}">

<telerik:RadScheduleView x:Name="scheduleView1" AppointmentsSource="{Binding Appointments}" >

<telerik:RadScheduleView.ViewDefinitions>

<telerik:DayViewDefinition MajorTickLength="1h" MinorTickLength="30min" />

<telerik:WeekViewDefinition />

</telerik:RadScheduleView.ViewDefinitions>

</telerik:RadScheduleView>

</telerik:RadBusyIndicator>

the above sample. Your project stopped working as well. You can just add IsLoading property, and set it is false. RadBusyIndicator is to set hourglass It may be a bug, please research.

Thanks

Hi Yana,
For me FirstVisibleTime is not yet working.

What I am trying to do is, when user comes to Day View , view should scroll to the first appointment in the day. Similarly when user open Week view, view should scroll to first appointment in the week.

For this I am using VisibleRangeChanged event of RadScheduleView. Since the FirstVisibleTime does not work for me I am now using ScrollTimeRuler() method. It works fine except in few cases like:

1. when user switches between Month View and any other view
2. When user clicks on Group Header in month view, it open the week view but does not scroll correctly

if (calendarView.ActiveViewDefinition.GetType() != typeof(MonthViewDefinition))

{

//get the first appointment in the visible date range

CalendarItemVM firstAppointmentOfDay = ((List<CalendarItemVM>)calendarView.AppointmentsSource).Where(p => p.Start >= calendarView.VisibleRange.Start

&& p.Start < calendarView.VisibleRange.End).OrderBy(o => o.Start).FirstOrDefault();

if (firstAppointmentOfDay != null)

calendarView.ScrollTimeRuler(firstAppointmentOfDay.Start.TimeOfDay, true, true);

else

calendarView.ScrollTimeRuler(new TimeSpan(8, 0, 0), true, true);

}

Any idea if this is a bug.

Hi Pooja,

Could you please try it with a Dispatcher like this:

if (calendarView.ActiveViewDefinition.GetType() != typeof(MonthViewDefinition))

{

Dispatcher.BeginInvoke(new Action(() =>

{

//get the first appointment in the visible date range

CalendarItemVM firstAppointmentOfDay = ((List<CalendarItemVM>)calendarView.AppointmentsSource).Where(p => p.Start >= calendarView.VisibleRange.Start

&& p.Start < calendarView.VisibleRange.End).OrderBy(o => o.Start).FirstOrDefault();

if (firstAppointmentOfDay != null)

calendarView.ScrollTimeRuler(firstAppointmentOfDay.Start.TimeOfDay, true, true);

else

calendarView.ScrollTimeRuler(new TimeSpan(8, 0, 0), true, true);

}));

}

It works as expected at our side.

Kind regards,

Hi!

I haven't yet figured it out.

I tried the same (dispatcher), and it got a little better, since before this workaround it would go to 1am, not it's going to 4am, but the line of code clearly says 8am...

private void SchedulerVisibleRangeChanged(object sender, EventArgs e)

{

//scroll to position

if (scheduler.ActiveViewDefinition.GetType() != typeof(MonthViewDefinition))

{

Dispatcher.BeginInvoke(new Action(() =>

{

scheduler.ScrollTimeRuler(new TimeSpan(8, 0, 0), true, true);

}));

}

I am using WPF by the way, but this post was the one more close to my issue at the moment.

Thanks in advance...
