Hello, I use the chart with binding for the data and the label.


// Model
public class StatisticRowItem
{
public double ValueDouble { get; set; }
public string Value { get; set; }
public string Name { get; set; }
}// ViewModel
public class ViewModel 
{
 public ObservableCollection<StatisticRowItem> RowItemList { get; set; }
}

If only the values are bound, the calculation of the percentage values is correct.

<telerik:RadPieChart Grid.Row="1" Palette="{StaticResource customPalette}">
    <telerik:RadPieChart.Series>
        <telerik:DoughnutSeries
            InnerRadiusFactor="0.35"
            ItemsSource="{Binding RowItemList}"
            RadiusFactor="0.50">
            <telerik:DoughnutSeries.ValueBinding>
                <telerik:PropertyNameDataPointBinding PropertyName="ValueDouble" />
            </telerik:DoughnutSeries.ValueBinding>
            <telerik:DoughnutSeries.LabelConnectorsSettings>
                <telerik:ChartSeriesLabelConnectorsSettings />
            </telerik:DoughnutSeries.LabelConnectorsSettings>
        </telerik:DoughnutSeries>
    </telerik:RadPieChart.Series>
</telerik:RadPieChart>

However, if the value and the label are linked, the calculation is incorrect.

<telerik:RadPieChart Grid.Row="1" Palette="{StaticResource customPalette}">
    <telerik:RadPieChart.Series>
        <telerik:DoughnutSeries
            InnerRadiusFactor="0.35"
            ItemsSource="{Binding RowItemList}"
            RadiusFactor="0.50">
            <telerik:DoughnutSeries.ValueBinding>
                <telerik:PropertyNameDataPointBinding PropertyName="ValueDouble" />
            </telerik:DoughnutSeries.ValueBinding>
            <telerik:DoughnutSeries.LabelDefinitions>
                <telerik:ChartSeriesLabelDefinition Margin="-15,0,0,0">
                    <telerik:ChartSeriesLabelDefinition.Template>
                        <DataTemplate>
                            <StackPanel>
                                <TextBlock
                                    Foreground="{DynamicResource Brushes.Text.Dark}"
                                    Text="{Binding DataItem.Name}"
                                    Style="{StaticResource ControlBase.FontStyle.ButtonText}" />
                                <TextBlock
                                    HorizontalAlignment="Center"
                                    Foreground="{DynamicResource Brushes.Text.Dark}"
                                    Style="{StaticResource ControlBase.FontStyle.ButtonText}"
                                    Text="{Binding Value}" />
                                <TextBlock
                                    HorizontalAlignment="Center"
                                    Foreground="{DynamicResource Brushes.Text.Dark}"
                                    Style="{StaticResource ControlBase.FontStyle.ButtonText}"
                                    Text="{Binding Percent}" />
                            </StackPanel>
                        </DataTemplate>
                    </telerik:ChartSeriesLabelDefinition.Template>
                </telerik:ChartSeriesLabelDefinition>

            </telerik:DoughnutSeries.LabelConnectorsSettings>

MaterialPalette ignores color changes

Hi,

I have migrated a .NET 4.8 app to .NET 8.0. In the app I define some colors for the MarterialPalette in App.xaml.cs via

StyleManager.ApplicationTheme = new MaterialTheme();
MaterialPalette.Palette.PrimaryNormalColor = Colors.Red;

Long story short, when I use a Telerik control it ignores the changes done at the palette.

I tried to create a small project to comprehend the problem, but unfortunately I was not able reproduce it on a simple basis.

So, my question is: Are there any konwn problems with the theming to take over changes that should appear globally?

Thanks in advance.

RadCartesianChart3D camerarotaion event

I am using a RadCartesianChart3D in a WPF application, where the label along the y-axis on the horiziontal plane denotes a "Flow direction" displayed using an Arrow symbol.

When/if the user rotates the chart around the vertical z-axis, so that the chart is seen from the backside, the values of the Y-axsis are reversed, which in my case translated to the "flow direction" should be swapped, as in: I need to change the arrow symbol in the y-axis label from "Pointing Right" to "Pointing Left" (or the opposite).

I notice, that the RadCartesianChart3D is actually already "flipping" the text label as the chart is rotated.

Is there any way I can intercept this behaviour, eg. as a ChartRotated or LabelPositionUpdated event, as the user rotates the chart, so that I can change the Label text as needed?

Two images attached to illustrate what I try to accomplish

/Thanx

Drag and DropText outside of RichTextBox

I would like to drag text outside of a WPF RadRichTextBox into a different App.

It seems that dragging any text just outside of this control is not possible, not even within the same app.
IMHO the problem is, that text can be moved within this control, and this feature cannot be deactivated.

Thanks a lot in advance for any hints.

Edit: Just checked with standard RichTextBox (FlowControl) no problems out of the box. I can drag text internal and as soon as mousepointer went outside, everything is fine and works there. Try this with RadRichTextBox and the Prompt goes crazy inside of your control.

Change Visibility of RadBadge

Hello,

i'm using a RadButton with a RadBadge to open an dialog with new messages.

Now i'm wondering how to hide the RadBadge when there are no new messages...

In my viewmodel i have a property (bool) that indicates, if the badge should be visible or not...

Here's the XAML - its part of a datatemplate for a RadWindow:

<telerik:RadButton x:Name="manButton"  Grid.Column="7" Margin="10,6" Command="{Binding ShowManCommand}" Focusable="False">
    <telerik:RadButton.Content>
        <Image Source="{iconPacks:MaterialImage CommentTextMultipleOutline, Brush=White}" Margin="4" />
    </telerik:RadButton.Content>
    <telerik:RadBadge.Badge>
        <telerik:RadBadge BadgeType="ContentOnly"  AnchorPosition="1,1" Position="1.1,0.4" 
                          Geometry="{telerik:Geometry Type=Oval}" Background="Red" 
                          FontSize="12" Height="16" Width="28"
                          Content="{Binding ManMessageCount}" 
                          Visibility="{Binding IsManBadgeVisible, Converter={converter:BoolToVisibilityConverter}}"/>
    </telerik:RadBadge.Badge>
</telerik:RadButton>

Is there a possibility to hide/collapse the RadBadge? It seems that the visibility property isn't working...
