I think I have found i bug with selection with Alt-key on RadScheduleView.

I use a WeekViewDefinition as my active view definition. When I select a square by holding Alt-key while dragging the selection breaks if I have any group descriptions defined.
I have a minor tick length of 15 minutes. When my selection reaches the last tick of any day (after 23:45) the selection jumps to next day close to the time where my selection started.

I am attaching a video that illustrates the problem.

If I dont have any group description on my RadScheduleView I dont get this problem.

Here is my schedule view detinition:


        <telerik:RadScheduleView
            x:Name="ScheduleView"
            AppointmentsSource="{Binding Appointments}"

Hey,

I have set my TextField to ReadOnly but the RadPdfViewer doesnt react to it. Im getting a pdf File that im importing using the telerik PdfFormatProvider after that im trying to set some of the fields to readOnly like this: 

if (formField is TextBoxField textBox)
{
	if (field is not null)
	{
	
		textBox.Value = field.ViewValue(viewMode);
		if (field.VarType != 0)
			formField.IsReadOnly = true;
			
	}
}

 

Im sure its setting it because if i export it to a pdf the fields are set to ReadOnly but not in the Telerik PdfViewer

 

Thanks

Dominik

We updated our WPF Telerik controls from 2021.3.1109 to 2023.3.1114 and now our RadPDFViewer is not displaying text on some PDF documents. Please see before and after images. 

Before:

After:

The file is a form fill PDF document that has been flattened. This displays correctly in Acrobat, Acrobat Reader, Chrome and Edge. 

We also opened the file the 2023.3.1114 PDFViewer demo with the same results.

I want to hide YAxies when LineSeries is not showing.I have checkBoxes to show and hide LineSeries and property  bool IsLineSeriesVisible.

<telerik:LineSeries ItemsSource="{Binding data, Mode=OneWay}" CategoryBinding="time" ValueBinding="value" >
                        <telerik:LineSeries.VerticalAxis>
                            <telerik:LinearAxis x:Name="yaxis" HorizontalLocation="Right" Title="{global:LocalizeKey TitleResKey, Default='value'}">
                                <telerik:LinearAxis.Style>
                                    <Style TargetType="telerik:LinearAxis">
                                        <Style.Triggers>
                                            <DataTrigger Binding="{Binding IsLineSeriesVisible}" Value="False">
                                                <Setter Property="Visibility" Value="Collapsed" />
                                            </DataTrigger>
                                        </Style.Triggers>
                                    </Style>
                                </telerik:LinearAxis.Style>
                            </telerik:LinearAxis>
                        </telerik:LineSeries.VerticalAxis>
                    </telerik:LineSeries>

And this is my xaml, dataTrigger is not working when i remove trigger it hiddes yAxis but when i try to add trigger to hide axies when series is not showing it doesn`t do anything

Hello,

I am facing application crash issue with : Out of memory exception.

While analysing, we got to know that scatterDataPoint is taking more memory

 

I am trying to add multiple ScatterLineSeries in telerik:RadCartesianChart.

XAML Code :


<telerik:RadCartesianChart Palette="Windows8" MouseDoubleClick="RadCartesianChart_MouseDoubleClick">
            <telerik:RadCartesianChart.HorizontalAxis>
                <telerik:LinearAxis Minimum="0" 
                                    Maximum="5000"/>
            </telerik:RadCartesianChart.HorizontalAxis>
            <telerik:RadCartesianChart.VerticalAxis>
                <telerik:LinearAxis Minimum="0" 
                                     Maximum="10000" />
            </telerik:RadCartesianChart.VerticalAxis>
            <telerik:RadCartesianChart.Series>
                <telerik:ScatterLineSeries ItemsSource="{Binding}" YValueBinding="YValue" XValueBinding="XValue" BorderBrush="Red" StrokeThickness="3" Stroke="Red" />
                <telerik:ScatterLineSeries ItemsSource="{Binding}" YValueBinding="YValue" XValueBinding="XValue" BorderBrush="Red" StrokeThickness="3" Stroke="Blue" />
                <telerik:ScatterLineSeries ItemsSource="{Binding}" YValueBinding="YValue" XValueBinding="XValue" BorderBrush="Red" StrokeThickness="3" Stroke="Pink" />
                <telerik:ScatterLineSeries ItemsSource="{Binding}" YValueBinding="YValue" XValueBinding="XValue" BorderBrush="Red" StrokeThickness="3" Stroke="Yellow" />
                <telerik:ScatterLineSeries ItemsSource="{Binding}" YValueBinding="YValue" XValueBinding="XValue" BorderBrush="Red" StrokeThickness="3" Stroke="Green" />
                <telerik:ScatterLineSeries ItemsSource="{Binding}" YValueBinding="YValue" XValueBinding="XValue" BorderBrush="Red" StrokeThickness="3" Stroke="Orange"/>
                <telerik:ScatterLineSeries ItemsSource="{Binding}" YValueBinding="YValue" XValueBinding="XValue" BorderBrush="Red" StrokeThickness="3" Stroke="AliceBlue" />
                <telerik:ScatterLineSeries ItemsSource="{Binding}" YValueBinding="YValue" XValueBinding="XValue" BorderBrush="Red" StrokeThickness="3" Stroke="Black" />
                <telerik:ScatterLineSeries ItemsSource="{Binding}" YValueBinding="YValue" XValueBinding="XValue" BorderBrush="Red" StrokeThickness="3" Stroke="Violet" />
                <telerik:ScatterLineSeries ItemsSource="{Binding}" YValueBinding="YValue" XValueBinding="XValue" BorderBrush="Red" StrokeThickness="3" Stroke="Cornsilk" />
            </telerik:RadCartesianChart.Series>
        </telerik:RadCartesianChart>

 

I am updating value in specific time intervarl. Example:

We have created 1 observable collection in which we are adding plot values(xaxis,yaxis)


public class PlotInfo
        {
            public double XValue { get; set; }
            public double YValue { get; set; }
        }

ObservableCollection<PlotInfo> ColPlotInfo = new ObservableCollection<PlotInfo>();

//Initially adding 100 records in observable collection & binding values to CartesianChart series.

            ArrayPlotInfo = arrayPlotInfo = new ChartViewModel.PlotInfo[100];
            for (int i = 0; i<100; i++)
                {

                ColPlotInfo.Add(new ChartViewModel.PlotInfo() { XValue = i + 100, YValue = i + 101 });
                }

On double click of chart, we are adding records on Timer_Elapsed.


private void RadCartesianChart_MouseDoubleClick(object sender, MouseButtonEventArgs e)
        {
            Timer timer = new Timer(100);
            timer.Enabled = true;
            timer.Elapsed += Timer_Elapsed;
            
        }
private void Timer_Elapsed(object sender, ElapsedEventArgs e)
        {

            App.Current.Dispatcher.Invoke((Action)delegate
            {
                ChartViewModel.PlotInfo plotInfo = new ChartViewModel.PlotInfo() { XValue = (x = x + DateTime.Now.Second), YValue = DateTime.Now.Second };
                ColPlotInfo.Add(plotInfo);
            });
}

Here if we do not bind to series then memory is not icreaseing it only increases when we update graph and application gets crashed.

I tried many things like –

  1. Used the items virtualization feature and restrict the viewport
  2. Tried different rendering options for ScatterLineSeries.
  3. Kept minimum bindings
  4. Used ObservableCollection for binding datapoints
  5. Enabled caching

 

Can anyone please help me with this? What else can I try so that memory increasing will be restrict?

Target Application : WPF

.Net Framework : 4.6.2

Telerik Version : 2017.2.503.45 (Telerik.Windows.Controls)

 

Hi

We are using RadBusyIndicator control for the client application, which raising the bellow exception randmoly on Production for long time.

Unfortunately it is not reproducible in development environment.

But as per the AppInsight log, assuming that happens on StoaryBoard animation as highlighted in the below style code.


Collection was modified; enumeration operation may not execute.

Type: System.InvalidOperationException
Message: Collection was modifined; enumeration operation may not execute.

And following is the style used for the busy indicator. There is no clue to find the root cause except this exception log.

I am using a RadCardView for the first time, and nothing is displaying.  I have followed the online sample code, and even replaced the Rad Card View with a list box to make sure the bindings are working, and still nothing appears to be displaying in the area where the CardView (previously a list box) should display.  Here is part of my code: 

    <telerik:RadCardView x:Name="cardView" Margin="5" 
                                     ItemsSource="{Binding Instruments}"
                                     MinorLength="140" AutoGenerateDataFieldDescriptors="False" 
                                     Grid.Row="1" >
                <telerik:RadCardView.CardHeaderTemplate>
                    <DataTemplate>
                        <Grid>
                                <Grid.ColumnDefinitions>
                                    <ColumnDefinition Width="Auto"></ColumnDefinition>
                                    <ColumnDefinition Width="*"></ColumnDefinition>
                                </Grid.ColumnDefinitions>
                                <telerik:RadRadioButton VerticalAlignment="Center" BorderThickness="0" IsHitTestVisible="False" Width="15" Height="15" Margin="10,0" Background="{Binding ConnectivityColor}" CornerRadius="30" Grid.Row="0" Grid.Column="0"></telerik:RadRadioButton>

                                <Grid DataContext="{Binding }" Grid.Row="0" Grid.Column="1">
                                    <Grid.ToolTip>
                                        <StackPanel Orientation="Horizontal">
