Change the amount of days in timeline view

[Scott]

Is there any way to increase or decrease the amount of days that are shown in the timeline view? Currently it is one week but I'd like to be able to change it to 1 or 2 weeks and perhaps 1 month.

Hello Scott,

You could use the VisibleDays property of the TimelineViewDefinition.

All the best,

That works great Valeri. I have the VisibleDays property bound to a slider and all works well except for one thing.

The date chooser at the top right of the control always scrolls by 7 days. So, for instance, I have VisibleDays set to 2 when the user presses the left or right arrows of the date chooser it always scrolls by 7 days.

Is there any way to have the date chooser skip days by the same setting as VisibleDays? Spcifically in the template I see this:

<telerik:RadButton Style="{StaticResource NavigationButtonBackStyle}" Command="local:RadScheduleViewCommands.DecreaseVisibleDateLarge" />
<telerik:RadDatePicker x:Name="PART_NavigationPicker" Style="{StaticResource NavigationDateTimePickerStyle}" SelectedValue="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=CurrentDate, Mode=TwoWay}" />
<telerik:RadButton Style="{StaticResource NavigationButtonNextStyle}" Command="local:RadScheduleViewCommands.IncreaseVisibleDateLarge" />

The two RadButtons increase and decrease the date by 7 can this be changed to match the VisibleDate?

Hi Scott,

You need to set the SmallChangeInterval. It is of type Telerik.Windows.Controls.ScheduleView.DateTimeInterval so you will have to use a ValueConverter if you are binding it to the VisibleDays property...

I actually needed to bind VisibleDays to LargeChangeInterval and that did the trick.

Hey guys,

it''s resolved, actually the format of value was causing error.
LargeChangeInterval="1d"
