calculating average value of a spline in an given interval

Hello everyone,

maybe thats more a mathematical question but i have a spline series for which i want to calculate the average value for in an given interval. what would be the best way to do this?
is there for example an way to get the interpolated value of the series at a certain position?

like for example i have the datapoints (x,y):
(13:15, 200), (13:57, 154),..., (18:31, 177)
now i like to know whats the average value between 15:30 and 17:30 o'clock .. which can be an interval in which i might have no 'real' values at all but only interpolated ones..

thanks in advance!

Problems scanning RadBarcode39

I am using RadBarcode39 in my Windows Phone 8 App but it is not being scanned correctly. So was wondering if there are recommendations for Height and Width properties to get it to scan properly. Also the bars don't appear to match a printed paper bar code. Below is what I am doing. Should I be doing something more/different ?

            <telerikDataViz:RadBarcode39 Name="BarCodeControl"
                                         Height="120"
                                         Width="425"
                                         Margin="5"
                                         VerticalAlignment="Center"
                                         HorizontalAlignment="Center"
                                         Text="90321331" 
                                         ShowChecksum="False"/>

Change Selected Pane in codebehind

Hello
We have the following View structure:

<RadDocking x:Name="_radDocking" RadDocking.SerializationTag="_radDocking">
    <RadDocking.DocumentHost>
      <telerik:RadSplitContainer x:Name="_splitContainer" RadDocking.SerializationTag="_splitContainer" InitialPosition="DockedTop">
        <telerik:RadPaneGroup x:Name="_contentArea" RadDocking.SerializationTag="_contentArea" IsContentPreserved="True" >
        </telerik:RadPaneGroup>
      </telerik:RadSplitContainer>
    </RadDocking.DocumentHost>
</RadDocking>

Inside code behind we add some RadPane to the PaneGroup. This works good.

Now we have the requirement to change the selected Pane in the case they are "groupped" after 2s. User should see each pane without a click.

In the case we have 4 RadPane:
Pane1 - Pane2 - Pane3 - Pane4 - Pane1 - Pane2 .....

The timer is not the problem. But how can I set the RadPane with should have focus inside codebehind?

Thanks

Implicit Style Radial Ranges

I have a solution where I am using the implicit themes and have a pallete switchers similar to what your Executive Dashboard is using. I have set up different gauge properties to switch when I click the theme toggle button. But i can not get the GaugeRange backgrounds to change. In fact they don't even display. Here is some sample code

<telerik:RadialScale x:Name="innerChannelRadialScale" Min="0" Max="300" Radius="0.68" MajorTicks="10" MinorTicks="5" LabelRotationMode="None"

FontWeight="Bold" FontSize="60" SweepAngle="359" StartAngle="90" ShowLastLabel="True" ShowFirstLabel="False"

MajorTickBackground="{DynamicResource MajorTickBackground}"

MiddleTickBackground="{DynamicResource MiddleTickBackground}"

MinorTickBackground="{DynamicResource MinorTickBackground}">

<telerik:RadialScale.Ranges>

<telerik:GaugeRange x:Name="innerAlarmLowRange" Min="0" Max="50" StartWidth="0.04" EndWidth="0.01" Background="{DynamicResource AlertRangeBackground}" />

<telerik:GaugeRange x:Name="innerNormalRange" Min="50" Max="250" StartWidth="0.01" EndWidth="0.01" Background="{DynamicResource NormalRangeBackground}" />

<telerik:GaugeRange x:Name="innerAlarmHighRange" Min="250" Max="300" StartWidth="0.01" EndWidth="0.03" Background="#FFE50000" />

</telerik:RadialScale.Ranges>

You will see I have set up DynamicResources for all of the Tick Backgrounds and they work perfectly. But the GaugeRange backgrounds do not work at all. In fact they do not show up at all. Is there something special I need to do to set DynamicResources on these?

Combining ItemsSource with Items.

I'd like to have two top-level TreeView items, which are not related to bindings. Simple hard coded top-level items. However, those items will have children. And those children will be from my VM.

Something like this:

<telerik:RadTreeViewItem

ItemsSource="{Binding DataContext.Documents, RelativeSource={RelativeSource AncestorType={x:Type telerik:RadTreeView}}}">

<TextBlock

Text="Documents" />

</telerik:RadTreeViewItem>

<telerik:RadTreeViewItem

ItemsSource="{Binding DataContext.Pages, RelativeSource={RelativeSource AncestorType={x:Type telerik:RadTreeView}}}">

<TextBlock

Text="Excluded Pages" />

</telerik:RadTreeViewItem>

However, this doesn't seem to be allowed. How can I accomplish this? Essentially, my VM has two collections of stuff, and I want to show both in a single tree view, but without introducing a bunch of stuff into my view model.

[Solved] Validation problem

Hi,

I have a MVVM application which showed a strange behavior.
To reproduce it I "switched to event mode" which has:

<telerik:RadGridView Grid.Row="1" ItemsSource="{Binding Bearings}" AutoGenerateColumns="False" ShowInsertRow="True" ShowGroupPanel="False" RowValidating="RadGridView_RowValidating" CanUserDeleteRows="True" CanUserInsertRows="True">

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn Header="Ordnungszahl" Width="*" DataMemberBinding="{Binding Ordnungszahl}" IsFilterable="True" SortMemberPath="Ordnungszahl" IsSortable="True" />

<telerik:GridViewDataColumn Header="BauartenCode" DataMemberBinding="{Binding BauartenCode}" Width="120" IsFilterable="False" IsSortable="True" />

<telerik:GridViewDataColumn Header="AussenDMCode" DataMemberBinding="{Binding AussendurchmCode}" Width="120" IsFilterable="False" IsSortable="False" />

<telerik:GridViewDataColumn Header="Stufe" DataMemberBinding="{Binding Stufe}" Width="120" IsFilterable="False" IsSortable="False" />

<telerik:GridViewDataColumn Header="Unterstufe" DataMemberBinding="{Binding Unterstufe}" Width="120" IsFilterable="False" IsSortable="False"/>

</telerik:RadGridView.Columns>

</telerik:RadGridView>

In code behind I do nothing more than:

private void RadGridView_RowValidating(object sender, Telerik.Windows.Controls.GridViewRowValidatingEventArgs e) {

e.IsValid = false;

}

When I hit ESC twice - editing is ended and the "old values" are displayed - but the row still displays "invalid" (red exclamation mark, red background).

What I expect is that the row becomes valid since it has the original (valid) values after "CancelEdit" (Hitting ESC twice).

The second problem (in debug) I get a "ArgumentNullException" (Parameter instance must not be null) when I add a row without entering anything hit ESC twice.
