HourInterval not displaying

[DSamani]

I can't seem to get the hour interval to work the way I expect it to.

If I use either this:

<Rad:RadTimeBar.Intervals>
	<Rad:MonthInterval />
	<Rad:DayInterval />
	<Rad:HourInterval />
</Rad:RadTimeBar.Intervals>

or this:

<Rad:RadTimeBar.Intervals>
	<Rad:MonthInterval />
	<Rad:DayInterval />
	<Rad:HourInterval  IntervalSpans="1" />
</Rad:RadTimeBar.Intervals>

I am unable to zoom into the 'hourly mode' (see first screenshot).  However 

<Rad:RadTimeBar.Intervals>
	<Rad:MonthInterval />
	<Rad:DayInterval />
	<Rad:HourInterval  IntervalSpans="1,8" />
</Rad:RadTimeBar.Intervals>


allows me to get into the hourly mode but shows the 8 hour interval (which I don't really want). Am I doing something wrong?


The rest of the xaml ( mPlotsGrid is populated with RadLinearSparklines at runtime):
                  <Rad:RadTimeBar Name="mTimeBar"
                                  PeriodStart="{Binding Path=BeginHistory, Mode=TwoWay}"
                                  PeriodEnd="{Binding Path=EndHistory, Mode=TwoWay}"
                                  VisiblePeriodStart="{Binding Path=BeginView, Mode=TwoWay}"
                                  VisiblePeriodEnd="{Binding Path=EndView, Mode=TwoWay}"
                                  SelectionStart="{Binding Path=BeginDetail, Mode=TwoWay}"
                                  SelectionEnd="{Binding Path=EndDetail, Mode=TwoWay}"
                                  IsSnapToIntervalEnabled="True"
                                  MinSelectionRange="00:01:00"
                                  Margin="5">
                     <Rad:RadTimeBar.Intervals>
                        <Rad:MonthInterval />
                        <Rad:WeekInterval />
                        <Rad:DayInterval />
                        <Rad:HourInterval  IntervalSpans="1,8" />
                     </Rad:RadTimeBar.Intervals>
                     <Grid x:Name="mPlotsGrid" />
                  </Rad:RadTimeBar>

Hi Byron Blattel,

In case you are using the latest version of RadTimeBar for WPF - Q3 2012, you can specify a small value for the MinZoomRange property of the control that fits your requirements. By default, the value of this property is calculated in such a way, so that the width of the content panel does not become more than 30 000 pixels. As of Q3 2012 you can specify a custom value for this property.

I take it that property doesn't work properly in Q2 2012?

I just tried to install Q3 and the new installer is giving me problems.

Thank you Tsvetie ,

I got past the zoom issue with Q3  However the MinZoomRange doesn't seem to be limiting the zooming to what I define.  For example if I set it to MinZoomRange="01:00:00" I would expect the control to stop zooming when the VisiblePeriod was less than a day and MinZoomRange="00:06:00" would stop zooming when the VisiblePeriod was less than 6 hours...

The documentation doesn't really indicate how MinZoomRange is supposed to work...

Hello Byron,

One thing here, maybe this is the case. This: "MinZoomRange="01:00:00" is actually 1 hour, 1 day should be defined like this: "1.00:00:00" (day.hours:minutes:seconds). Same is for MinZoomRange="00:06:00"  which is 6 minutes.

Hi Byron,

Stanescu Mihai is correct. The MinZoomRange property is of type TimeSpan. In order to set its value in XAML, you can use the syntax "[days.]hours:minutes:seconds[.fractionalSeconds]".

All the best,
