Is there any way to set the PieChart slice colors from code behind?  I know how to do it with other chart styles (i.e. for line charts .. I use <series>.Definition.Appearance.Stroke/Fill).  But when you use that same idea for pie charts, all the slices are the same color.  Which I expect since I've only got one series.

            var series = new DataSeries { Definition = new PieSeriesDefinition() };
            series.Definition.ShowItemLabels = true;
            series.Add(new DataPoint(_dataList.A, _dataList.A));
            series.Add(new DataPoint(_dataList.B, _dataList.B));

            //series[0].LegendLabel = "Series A";
            //series[1].LegendLabel = "Series B";

            // this is what I do in other charts for each series... but pie charts don't work.
            //series.Definition.Appearance.Stroke = new SolidColorBrush(Colors.Black);
            //series.Definition.Appearance.Fill = new SolidColorBrush(myCustomColor);

            RadChart1.DefaultView.ChartArea.DataSeries.Add(series);

If I change the theme colours in XAML using the StylesPalette, the colors change.  But I really want to change them from code (dynamic when a user control starts up only, not necessarily dynamic while the app is running).   Any ideas?  Could the color of of the Fill property in the Xaml be changed using binding?

            <SolidColorBrush x:Key="RadialItemStroke" Color="#FF000000"/>
            <system:Double x:Key="RadialItemStrokeThickness">2</system:Double>
            <telerikStyling:StylesPalette x:Key="{telerikStyling:ThemeResourceKey
                    ThemeType={x:Type telerikStyling:Office_BlackTheme},
                    ElementType={x:Type telerikStyling:ChartArea},
                    ResourceId={x:Static telerikStyling:ResourceHelper.ResourceKeyRadialStyle}}">
                <Style TargetType="{x:Type Shape}">
                    <Setter Property="Stroke" Value="{StaticResource RadialItemStroke}" />
                    <Setter Property="StrokeThickness" Value="{StaticResource RadialItemStrokeThickness}" />
                    <Setter Property="Fill" Value="{Insert some binding expression here?}" />
                </Style>
                <Style TargetType="{x:Type Shape}">
                    <Setter Property="Stroke" Value="{StaticResource RadialItemStroke}" />
                    <Setter Property="StrokeThickness" Value="{StaticResource RadialItemStrokeThickness}" />
                    <Setter Property="Fill" Value="{Insert some binding expression here?}" />
                </Style>
            </telerikStyling:StylesPalette>

Hi,
Can I rotate a group of some RadDiagramShape?

My problem is when I put beside more shapes and I group theme. Afterthat I would rotate a group to 90°

 

I have multiple charts that share the same x-axis and have the trackballs grouped using chartviewutilities.cs from one of your examples. Everything works as expected when there is no zoom. However as soon as I throw a grouped zoom and pan into the mix the trackballs get out of sync. The further I zoom the more out of sync they become. How can i resolve this? 

Here is my charts xaml:

   <telerik:RadCartesianChart Margin="0,17,0,5" TrackBallInfoStyle="{StaticResource trackBallInfoStyle}" TrackBallLineStyle="{StaticResource trackBallLineStyle}" utils:ChartViewUtilities.ChartAlignmentGroup="g1" UseLayoutRounding="True" FontFamily="{DynamicResource FontFamilyRoboto}" Zoom="{Binding Zoom, Mode=TwoWay, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type View:MainWindow}}}" PanOffset="{Binding PanOffset, Mode=TwoWay, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type View:MainWindow}}}" MaxZoom="10000,10000">
            <telerik:RadCartesianChart.HorizontalAxis>
                <telerik:CategoricalAxis SmartLabelsMode="SmartStep" Title="Strip Length (meters)" MajorTickStyle="{StaticResource tickStyle}"/>
            </telerik:RadCartesianChart.HorizontalAxis>
            <telerik:RadCartesianChart.VerticalAxis>
                <telerik:LinearAxis SmartLabelsMode="SmartStepAndRange" MajorTickStyle="{StaticResource tickStyle}"/>
            </telerik:RadCartesianChart.VerticalAxis>
            <telerik:RadCartesianChart.Grid>
                <telerik:CartesianChartGrid MajorLinesVisibility="Y" MajorYLineDashArray="3,4"/>
            </telerik:RadCartesianChart.Grid>
            <telerik:RadCartesianChart.Behaviors>
                <telerik:ChartPanAndZoomBehavior ZoomMode="Horizontal" PanMode="Horizontal" />
                <telerik:ChartTrackBallBehavior ShowIntersectionPoints="True" 
                                                    utils:ChartViewUtilities.ShouldPositionTrackBallCloseToDataPoint="False"
                                                    utils:ChartViewUtilities.TrackBallGroup="g1" TrackInfoUpdated="ChartTrackBallBehavior_TrackInfoUpdated"/>
            </telerik:RadCartesianChart.Behaviors>
            <telerik:LineSeries x:Name="SteelDNALineSeries" CategoryBinding="Position" 
                                        ValueBinding="Value" 
                                        ItemsSource="{Binding Trace, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type local:ParameterTraceControl}}}"
                                        TrackBallTemplate="{StaticResource SteelDNATrackBallTemplate}" Stroke="{Binding RandomColor, Mode=OneWay, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type View:MainWindow}}}" StrokeThickness="1"
                                        utils:ChartAnimationUtilities.CartesianAnimation="Rise"/>
        </telerik:RadCartesianChart>

 

and attached are what happens...

Hello,
After using ScaleTransform to scale up the UI of our application the Compass and VisualCue elements are clipped to, what seems to be, the unscaled size of the RadDocking control.

I am scaling the application by adding

to the root element of the main window and setting the compass and visualcue scaling with

You can see the result in the attached image.
Are there other elements of the RadDocking control which I didn't set the scaling for, or am I approaching the whole scaling the wrong way ?

Hi,

I have a LocalDataSourceProvider bound to a DataTable. Some of the columns allow nulls and some of the values in them are DBNull. I would like to be able to display a count of the values that aren't null. I've created my own aggregate function and I can add that to some of my AggregatePropertyDescriptions programmatically. I do have an example, but apparently I'm only allowed to upload images.

The questions I've got are:

Is there any easier way to do this?

Can I make this aggregate function appear in the UI in the Field List, so users can select it?

I only appear to be able to apply this to my nullable int property, and not my string property. Is that something I should be expecting?

Many thanks,

Richard

Hi, I got the code from http://docs.telerik.com/devtools/wpf/controls/radgridview/columns/how-to/scroll-item

 

My code :

when DropRowIndex = 16 and the items.count=17 , it calls the scrollFailedCallback , I tried to make it this.timetableGrid.Items[this.timetableGrid.Items.Count -1] and it still fails. WHy? My items count is 17 so it should not be failing. I hardcoded it into DropRowIndex = 15 and it is calling scrollFinishedCallback which is what I want to happen. May I ask why rowindex 16 is not working ?

if (this.timetableGrid.Columns.Count > 0 && DropColIndex <= this.timetableGrid.Columns.Count)
            {
                IsScrollBarForceIntoView = false;
                int offsetCol = 0; int offsetRow = 0;
                if ((DropColIndex + 3) <= (this.timetableGrid.Columns.Count - 1))
                    offsetCol = 3;
                if ((DropRowindex + 3) <= (this.timetableGrid.Items.Count - 1))
                    offsetRow = 3;
                this.timetableGrid.ScrollIntoViewAsync(this.timetableGrid.Items[DropRowindex + offsetRow], //the row
                                this.timetableGrid.Columns[DropColIndex + offsetCol], //the column
                                 new Action<FrameworkElement>((f) =>
                                  {
                                      App.MainWindow.IsBusy = false;
                                  }), new Action ( ()=>
                                      {
                                          App.MainWindow.IsBusy = false;
                                      }
                                    ));
                isDrop = false;
            }
            else
            {
                App.MainWindow.IsBusy = false;
                DropColIndex = 0;
            }

I used all resource string files for RadPivotGrid, but the message "Blank" could not find the key for translation. What is the procedure for translating this message?

I have a test project demonstrating the problem but I am not allowed to post

Hi,

I'm using the Q3 2016 version of the Telerik WPF controls suite.  I'm having a problem using a ScatterLineSeries in tandem with the "Batch" option on XamlRenderOptions for the series.  I'm using a ChartSeriesDescriptor with a style for the ScatterLineSeries that has the following:

 

 

That "DefaultVisualStyle" resource is defined like so:

 

 

When I use those options and add data points via bindings from the ChartSeriesProvider, I get a MissingMethodException, that seems to come from the UIAutomation system:

 

 

Is there anything I can do to use Batch for performance on this series?

I try to open a contextmenu when i select many tasks/items in my ganttview, but when i click the right button, ganttview lost selecteditems and get just the item under my click.
How can i perform a contextmenu for two or many tasks?
Thank you
