we have recently updated to the current Telerik version from a 2013 version.  We have the following

 

<telerik:RadPieChart Palette="Windows8" Grid.Column="0" Grid.Row="0" ToolTip="Mill Department">

  <telerik:RadPieChart.Series>

    <telerik:PieSeries ValueBinding="CountOfMachines" ShowLabels="True" ItemsSource="{Binding MachinesUsedYesterByCustomerInMill}" RadiusFactor="0.35">

       <telerik:PieSeries.LabelDefinitions>

          <telerik:ChartSeriesLabelDefinition Binding="Customer" Margin="-8,0,0,0">

               <telerik:ChartSeriesLabelDefinition.Template>

                    <DataTemplate>

                         <StackPanel>

                             <TextBlock Text="{Binding DataItem.Customer}" Margin="0"/>

                       </StackPanel>

                  </DataTemplate>

              </telerik:ChartSeriesLabelDefinition.Template>

          </telerik:ChartSeriesLabelDefinition>

       </telerik:PieSeries.LabelDefinitions>

     </telerik:PieSeries>

   </telerik:RadPieChart.Series>

</telerik:RadPieChart>

 

_______________

Before the upgrade this worked fine, now the chart still comes out, but no labels are on it.  What needs to change to have the labels show up now?

Hello,

I want to know the number of filter values in my RadGridView.

I know that gridVariables.FilterDescriptors.Count gives me the value '0' or '1' if a filter value is selected, but, i don't find how i can get the number of selected values in the filter.

 

Thank you.

 

Valentin.

I am working on a project that takes some basic controls and some telerik wpf controls, places them on a canvas, and saves these for redisplay later. All of the controls are generated at runtime.

Whenever I attempt to save the Xaml of a RadChart, after approximately 30 seconds, the XamlWriter.Save method throws a StackOverflow exception. The problem is reproducible.

Create project referencing the .NET Framework 4.

Telerik.Window.Controls
Telerik.Window.Controls.Chart
Telerik.Window.Controls.Charting
Telerik.Window.Controls.Data
Telerik.Window.Controls.DataVisualization
Telerik.Window.Data

Place the following code on a new window:

<Canvas Name="testCanvas" Height="350" Width="525">
    <telerik:RadChart Name="testChart" Height="350" Width="525"/>
</Canvas>

Place this in code-behind:

public MainWindow()
{
    InitializeComponent();
    this.PreviewMouseDoubleClick += Window_PreviewMouseDoubleClick;
    testCanvas.Loaded += testCanvas_Loaded;
}
private void testCanvas_Loaded(object sender, RoutedEventArgs e)
{
    testChart.DefaultView.ChartLegend.UseAutoGeneratedItems = true;
    Telerik.Windows.Controls.Charting.DataSeries barSeries = new Telerik.Windows.Controls.Charting.DataSeries();
    barSeries.LegendLabel = "Expenses";
    barSeries.Definition = new Telerik.Windows.Controls.Charting.BarSeriesDefinition();
    barSeries.AddRange(new List<Telerik.Windows.Controls.Charting.DataPoint> {
        new Telerik.Windows.Controls.Charting.DataPoint() { YValue = 45, XCategory = "Jan" },
        new Telerik.Windows.Controls.Charting.DataPoint() { YValue = 48, XCategory = "Feb" },
        new Telerik.Windows.Controls.Charting.DataPoint() { YValue = 53, XCategory = "Mar" },
        new Telerik.Windows.Controls.Charting.DataPoint() { YValue = 41, XCategory = "Apr" },
        new Telerik.Windows.Controls.Charting.DataPoint() { YValue = 32, XCategory = "May" },
        new Telerik.Windows.Controls.Charting.DataPoint() { YValue = 28, XCategory = "Jun" },
        new Telerik.Windows.Controls.Charting.DataPoint() { YValue = 63, XCategory = "Jul" },
        new Telerik.Windows.Controls.Charting.DataPoint() { YValue = 74, XCategory = "Aug" },
        new Telerik.Windows.Controls.Charting.DataPoint() { YValue = 77, XCategory = "Sep" },
        new Telerik.Windows.Controls.Charting.DataPoint() { YValue = 85, XCategory = "Oct" },
        new Telerik.Windows.Controls.Charting.DataPoint() { YValue = 89, XCategory = "Nov" },
        new Telerik.Windows.Controls.Charting.DataPoint() { YValue = 80, XCategory = "Dec" }
    });
    testChart.DefaultView.ChartArea.DataSeries.AddRange(new List<Telerik.Windows.Controls.Charting.DataSeries> { barSeries });
}
 
private void Window_PreviewMouseDoubleClick(object sender, MouseButtonEventArgs e)
{
 
    var fileName = @"c:\temp\tester.xaml";
    using (var fs = new FileStream(fileName, FileMode.Create, FileAccess.Write, FileShare.Read))
    using (var xw = new XmlTextWriter(fs, System.Text.Encoding.UTF8))
    {
        xw.Formatting = Formatting.Indented;
        xw.Indentation = 4;
        xw.IndentChar = ' ';
 
        //place breakpoint here
        XamlWriter.Save(testCanvas, xw);
    }
}

Run project and then double-click the window. At the "XamlWriter.Save(testCanvas, xw)", a stackoverflow exception will eventually occur

Please let me know what I can do to correct this issue.

 

Thanks

I am working on a project that takes some basic controls and some telerik wpf controls, places them on a canvas, and saves these for redisplay later. All of the controls are generated at runtime.

One problem I am having is with some of the relative and scale values on all gauge controls that use the Telerik.Windows.Controls.Gauge.GaugeMeasure for storing values. instead of saving the actual value set on the property (such as 0.15*), when I save the Xaml, I get the text "Telerik.Windows.Controls.Gauge.GaugeMeasure" as the property value.

To reproduce, place the following on a wpf window:

<Border Name="meterBorder" BorderThickness="1" BorderBrush="Black" Background="White" Width="80" Height="300" CornerRadius="3">
        <telerik:RadVerticalLinearGauge Padding="5" Background="Transparent" BorderThickness="0" OuterBackground="Transparent" OuterBorderThickness="0" >
            <telerik:VerticalLinearScale Min="0" Max="1" RelativeY="0" RelativeHeight="0.9" VerticalAlignment="Center" Fill="#FF787878" StartWidth="0.015" EndWidth="0.015" MajorTickOffset="0.0" MinorTickOffset="0.0" MiddleTicks="1" MinorTicks="2" MajorTickStep="0.1" MajorTicks="10" LabelFormat="{}{0:F2}" LabelLocation="OverOutside" MajorTickLocation="Outside" Margin="10" FontSize="8" Foreground="Black" MajorTickStrokeThickness="1" MajorTickStroke="Black" MinorTickStrokeThickness="1" MinorTickStroke="Black">
                <telerik:VerticalLinearScale.Indicators>
                    <telerik:BarIndicator Name="valueIndicator" HorizontalAlignment="Left" Margin="-20,0,0,0" Value="0.5" Background="#FF7171FF" StartWidth="0.2" EndWidth="0.2" StrokeThickness="0" Width="13" />
                </telerik:VerticalLinearScale.Indicators>
                <telerik:VerticalLinearScale.Ranges>
                    <telerik:GaugeRange x:Name="LowLowIndicator"  Background="Red" StartWidth="0.05" EndWidth="0.05" Min="0" Max="0.05" IndicatorBackground="{x:Null}" />
                    <telerik:GaugeRange x:Name="LowIndicator" Background="#FFE8FF00" StartWidth="0.05" EndWidth="0.05" Min="0.05" Max="0.15" IndicatorBackground="{x:Null}" />
                    <telerik:GaugeRange x:Name="HighIndicator" Background="#FFE8FF00" StartWidth="0.05" EndWidth="0.05" Min="0.85" Max="0.95" IndicatorBackground="{x:Null}" TickBackground="{x:Null}" StrokeThickness="0" />
                    <telerik:GaugeRange x:Name="HighHighIndicator" Background="Red" StartWidth="0.05" EndWidth="0.05" Min="0.95" Max="1" IndicatorBackground="{x:Null}" />
                </telerik:VerticalLinearScale.Ranges>
            </telerik:VerticalLinearScale>
        </telerik:RadVerticalLinearGauge>
    </Border>

On top of code-behind:

using System.IO;
using System.Xml;
using System.Windows.Markup;

then in window MouseDoubleClick (or some other event) place the following to save the file:

var fileName = @"c:\temp\tester.xaml";
using (var fs = new FileStream(fileName, FileMode.Create, FileAccess.Write, FileShare.Read))
using (var xw = new XmlTextWriter(fs, System.Text.Encoding.UTF8))
{
 xw.Formatting = Formatting.Indented;
 xw.Indentation = 4;
 xw.IndentChar = ' ';
 
 
 XamlWriter.Save(meterBorder, xw);
}

throughout the saved Xaml, there will be numerous Telerik.Windows.Controls.Gauge.GaugeMeasure where values should be. Is this a bug in the Telerik controls, or is there some way for me to properly save the correct values for the telerik controls?

 

Thanks

Thanks

Hi,

I'm using: 

<telerikScheduleView:RadScheduleView x:Name="ScheduleView"...

 

and we have the custom localization going for Swedish, but I can't find the resource keys for the individual week days that you can see in Week view mode.

 

               case "Day":
                    return "Day[ENG]";
                case "Week":
                    return "Week[ENG]";
                case "Monday":
                    return "?????";

 

...in the end we need keys for ALL of the text strings, not just the subset as listed in:

http://docs.telerik.com/devtools/wpf/controls/radscheduleview/localization#radscheduleview-resource-keys

 

Thanks,

 

Barry

I have a RadCartesianChart with a DateTimeContinuousAxis and a ChartCrosshairBehavior.

When the vertical line label shows – it displays the date/time. I want to display other data from the chart too – but even when I use a template for the label definition – the only DataContext I can access is the datetime. 

Is there a way to customize the label definition - to include data from other sources?

In Microsoft Word and other text editors there is a ability which stretches the text horizontally. How should I do so in RadRichTextBox in WPF Apps.

Thanks
