I was wondering what the capabilities are of the Telerik charts. I want to chart live data as fast as possible without losing performance. The current way it is integrated, the performance is good, but after I like it chart for awhile, the performance starts to suffer and I start getting delayed responses and inaccuracies. I am trying to figure out of this is normal for Telerik controls or if it's something with the code that's written. Note: I am logging all the data as well to use for playback features, I realize this might be taking up system resources too?

RadPaneGroup DropDownMenu only on first group

If I have document panes in two RadPaneGroups, the dropdown list of open documents is only shown in the first group. Is this by design? And if so would it be possible to have it displayed in all groups? I've attached an image illustrating the current problem.
Thanks in advance,
Steve

trigger ChartTrackBallBehavior

Hi,
how can I trigger the ChartTrackBallBehavior programmatically?
In my scenario I set the chart IsManipulationEnabled to True. Since this I don't get the TrackBallInfo when I touch the chart. Is there a way to get around this?

Cheers,
Enrico

Nested InformationLayer

I have a collection of ScanSessions, each of which contains a collection of Waypoints. I have a RadGridView for displaying a list of the ScanSessions and I have another RadGridView for displaying the list of Waypoints in the selected ScanSession. I am also trying to write the XAML to create a RadMap InformationLayer that displays all the Waypoints for all the ScanSessions on a map. The reason for this is to make it easy to indicate on the map which Waypoint is selected in the grid view and vice versa.

I tried to do this by nesting one InformationLayer inside another as seen in the following XAML:

<UserControl.Resources>

<local:LocationToTelerikConverter x:Key="LocationToTelerikConverter"/>

<local:LocationCollectionToTelerikLocationCollectionConverter x:Key="LocationCollectionToTelerikLocationCollectionConverter"/>

<SolidColorBrush x:Key="ControlSubtleForegroundBrush" Color="#004100"/>

<DataTemplate x:Key="MapWaypointsTemplate">

<Grid Tag="{Binding}" telerik:MapLayer.Location="{Binding Path=Location, Converter={StaticResource LocationToTelerikConverter}}">

<telerik:MapLayer.HotSpot>

<telerik:HotSpot ElementName="WaypointEllipse" X="0.5" Y="0.5" XUnits="Fraction" YUnits="Fraction"/>

</telerik:MapLayer.HotSpot>

<Ellipse x:Name="WaypointEllipse" Width="20" Height="20" Fill="Blue"/>

</Grid>

</DataTemplate>

</UserControl.Resources>

<Grid Background="Black">

<telerik:RadMap x:Name="map" Background="Transparent" UseSpringAnimations="False" DistanceUnit="Kilometer" MouseClickMode="None" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"

UseDefaultLayout="False" MaxZoomLevel="24" MinZoomLevel="1" ZoomLevel="1"

MapMouseClick="OnMapMouseClick" CenterChanged="OnMapCenterChanged" ZoomChanged="OnMapZoomChanged" InitializeCompleted="OnMapInitializeCompleted" PreviewMouseMove="OnMapPreviewMouseMove"

>

<telerik:RadMap.Providers>

<telerik:EmptyProvider/>

</telerik:RadMap.Providers>

<telerik:InformationLayer x:Name="scanSessionSnailTrailLayer" ItemsSource="{Binding ElementName=_this, Path=ScanSessions}">

<telerik:InformationLayer.ItemTemplate>

<DataTemplate>

<telerik:MapPolyline Stroke="Blue" StrokeThickness="2" Points="{Binding Path=WaypointLocations, Converter={StaticResource LocationCollectionToTelerikLocationCollectionConverter}}"/>

</DataTemplate>

</telerik:InformationLayer.ItemTemplate>

</telerik:InformationLayer>

<telerik:InformationLayer x:Name="scanSessionWaypointsOuter" ItemsSource="{Binding ElementName=_this, Path=ScanSessions}">

<telerik:InformationLayer.ItemTemplate>

<DataTemplate>

<telerik:InformationLayer x:Name="scanSessionWayPointsInner" ItemsSource="{Binding Path=Waypoints}" ItemTemplate="{StaticResource MapWaypointsTemplate}"/>

</DataTemplate>

</telerik:InformationLayer.ItemTemplate>

</telerik:InformationLayer>

</telerik:RadMap>

</Grid>

The problem is that none of the Waypoint ellipses are displayed. I have also tried replacing both the outer and inner InformationLayer elements with simple ItemsControl elements, with no success.

Note that the InformationLayer named scanSessionSnailTrailLayer works just fine.

Does anybody have an idea how to get my nested InformationLayers to work?

Thanks,

Floating ToolWindows

When you double click on an email in Outlook, it open a floating window for the email, and the floating email contains its own Ribbon bar and also it shows in the windows taskbar. Could you provide suggestions how can we implement the behavior with RadControls?

We are using RadControl for WPF 2012.2.0607.40 with Prism (MVVM). The layout of our application is very similar to Outlook, and the main window is RadRibbonWindow, which contains a RadRibbonView, and a RadDocking is within the RadRibbonView. and, of course, RadDocking.DocumentHost host all documents. We would like each document has its own RibbonView IF THE DOCUMENT IS FLOATING, also we would like all floating ToolWidnows show in Window TaskBar.

Thanks.

Mouse Over Custom Annotation Effect

Hi there,

Does anyone know how to go about creating mouse over effects for custom annotations?
For example, if I "mouse over" between a custom annotation range I may want the font colour, or font size to change or to even highlight the annotation. Going even further, maybe have some way to activate a little popup window which in turn may display more detailed information about the annotation properties (I guess that's similar to the Comments Annotations feature).

Any information would be really handy.

Thanks for your time,

Rob

cell style based on another cell's value

Is it possible to set a cell's style based on the content of another cell in that row?

For example:
If CellA = 0 then CellB.Background = Red
If CellA = 1 then CellB.Background = White

If this is possible, can you please post a sample project that accomplishes this?

Thank you very much.
