Custom selection marker

Hi all,

I have successful customized my bar chart items, but now there is no selection marker visible. Here some code:

<Style x:Key="CustomBarStyle" TargetType="telerikCharting:Bar">

<Setter Property="Template">

<Setter.Value>

<ControlTemplate TargetType="telerikCharting:Bar">

<Canvas>

<Rectangle

x:Name="PART_DefiningGeometry"

Height="{TemplateBinding ItemActualHeight}"

Width="{TemplateBinding ItemActualWidth}"

Fill="Blue" />

<Canvas.RenderTransform>

<ScaleTransform x:Name="PART_AnimationTransform" ScaleY="0" />

</Canvas.RenderTransform>

</Canvas>

</ControlTemplate>

</Setter.Value>

</Setter>

</Style>

This is the style for my items. Fill is normaly a property of my item class.

<telerik:RadChart

x:Name="Chart" Grid.ColumnSpan="2" ItemsSource="{Binding BarChartList}">

<telerik:RadChart.DefaultView>

<telerikCharting:ChartDefaultView ChartLegendPosition="Bottom">

<telerikCharting:ChartDefaultView.ChartLegend>

<telerikCharting:ChartLegend Header="Legend" UseAutoGeneratedItems="false" ItemsPanelOrientation="Horizontal" >

<telerikCharting:ChartLegend.Items>

<telerikCharting:ChartLegendItem Label="label1" MarkerFill="Green" />

<telerikCharting:ChartLegendItem Label="label2" MarkerFill="Red" />

<telerikCharting:ChartLegendItem Label="label3" MarkerFill="Blue" />

<telerikCharting:ChartLegendItem Label="label4" MarkerFill="Orange" />

</telerikCharting:ChartLegend.Items>

</telerikCharting:ChartLegend>

</telerikCharting:ChartDefaultView.ChartLegend>

<telerikCharting:ChartDefaultView.ChartArea>

<telerikCharting:ChartArea ItemClick="ChartAreaItemClick" Annotations="{Binding BarChartAnnotations}">

<telerikCharting:ChartArea.AxisY>

<telerikCharting:AxisY AutoRange="False" MinValue="0" MaxValue="{Binding BarChartMax}" Step="10" />

</telerikCharting:ChartArea.AxisY>

<telerikCharting:ChartArea.AxisX>

<telerikCharting:AxisX AutoRange="False" MinValue="1" MaxValue="{Binding BarChartList.Count}" Step="1" />

</telerikCharting:ChartArea.AxisX>

</telerikCharting:ChartArea>

</telerikCharting:ChartDefaultView.ChartArea>

</telerikCharting:ChartDefaultView>

</telerik:RadChart.DefaultView>

<telerik:RadChart.AnimationSettings>

<telerikCharting:AnimationSettings ItemDelay="0:0:0" ItemAnimationDuration="0:0:0.2" />

</telerik:RadChart.AnimationSettings>

<telerik:RadChart.DefaultSeriesDefinition>

<telerikCharting:BarSeriesDefinition x:Name="BarSeries" ItemStyle="{StaticResource CustomBarStyle}">

<telerikCharting:BarSeriesDefinition.InteractivitySettings>

<telerikCharting:InteractivitySettings SelectionMode="Single" SelectionScope="Item" />

</telerikCharting:BarSeriesDefinition.InteractivitySettings>

</telerikCharting:BarSeriesDefinition>

</telerik:RadChart.DefaultSeriesDefinition>

<telerik:RadChart.SeriesMappings>

<telerikCharting:SeriesMapping SeriesDefinition="{Binding ElementName=BarSeries}">

<telerikCharting:SeriesMapping.ItemMappings>

<telerikCharting:ItemMapping FieldName="Value" DataPointMember="YValue" />

</telerikCharting:SeriesMapping.ItemMappings>

</telerikCharting:SeriesMapping>

</telerik:RadChart.SeriesMappings>

</telerik:RadChart>

And this is the chart control. I can select each item, ChartAreaItemClicked is fired, but there is noch border around the items. How can I place a csutom style for that?

Kind regards,
dpl

During Drag-and-drop -- how to enable Copy through pressing Ctrl?

Hi telerik,

Using the old implementation of drag-and-drop, we were able to copy-drag by catching the press of Ctrl key during the drag.

How do you recommend enabling this functionality using the new dragdropmanager?

Yours,

Drag-and-drop -- how to handle the move/copy myself?

Hi telerik,

After move to the new way of handling drag-and-drop, we've encountered a problem. Basically, we record in our viewmodel object behind the individual treeitem who the parent is. But currently, after the move to new drag-and-drop implementation, it would appear that the dragged item is repositioned 'out-of-the-box' and keeps it's viewmodel -- but in out world, this is now a wrong object.

Is there a way to prevent the drag-and-drop-manager from doing the actual move? I'd like to do it manually, updating the viewmodel and then notifying the treeview that sending/receiving items have changed...

Thanks,

Anders, Denmark

Possible bug in latest release

One hour ago I updated WPF RadControls to version "2013.2.724.45" and also my current project where I use Windows 8 theme for my RadMap. It seems that now there is a bug in that theme because I cannot drag, zoom or do anything else with my map. Other themes work fine.

Custom MapShape?

On my RadMap I have some InformationLayers and one of them is showing some objects as MapShape type "MapLine". Point1 and Point2 are set so the lines are displayed correctly. Now I have to extend those lines.

Our customer wants to see little bubbles at start and end point of each line. It seems a combination of MapShapes is not possible inside ItemTemplate so using one "MapLine" and two "MapEllipse" objects is not possible, right? As far as I understand the documentation one possibility is to use a single MapShape (that's what I currently have) and the other is using a FrameworkElement. But I cannot use FrameworkElement because those objects do not have Properties for RadMap like Point1/Point2 or Location.

ItemTemplate now:

<DataTemplate>

<tel:MapLine

Visibility="{Binding Visibility}"

StrokeThickness="{Binding LineThickness}"

Point1="{Binding Point1}"

Point2="{Binding Point2}" />

</DataTemplate>

What I expected as solution but didn't found

<DataTemplate>

  <

tel:MapShapeCollectionOrSomethingLikeThat>

<tel:MapEllipse tel:MapLayer.Location="{Binding Point1}" />

<tel:MapLine

Visibility="{Binding Visibility}"

StrokeThickness="{Binding LineThickness}"

Point1="{Binding Point1}"

Point2="{Binding Point2}" />

<tel:MapEllipse tel:MapLayer.Location="{Binding Point2}" />

</tel:MapShapeCollectionOrSomethingLikeThat>

</DataTemplate>
