I just want to disable (grayed-out, un-clickable) the "funnel" icon of the filter on the radgridview header and not HIDE it.
Is there easy way to do it without creating a custom filter?

Hello. I have the following XAML markup:

using Prism.Mvvm;using System;using Telerik.Windows.Data;namespace UltrasonicSensors.ViewModels{ /// <summary> /// Ultrasonic sensor signal ViewModel. /// </summary> public class SensorSignalChartViewModel : BindableBase { #region Fields /// <summary> /// Ultrasonic sensor signal chart point collection. /// </summary> private RadObservableCollection<Tuple<int, double>> _sensorData; /// <summary> /// Data missing Message. /// </summary> private object _chartEmptyContent; /// <summary> /// Chart header. /// </summary> private string _caption; #endregion #region Constructors /// <summary> /// Create instance of SensorSignalViewModel. /// </summary> /// <param name="aSensorData">Ultrasonic sensor signal chart point collection.</param> public SensorSignalChartViewModel(Tuple<int, double>[] aSensorData) { this.SensorData = new RadObservableCollection<Tuple<int, double>>(aSensorData); } #endregion #region Properties /// <summary> /// Gets or sets ultrasonic sensor signal chart point collection. /// </summary> public RadObservableCollection<Tuple<int, double>> SensorData { get { return this._sensorData; } set { this.SetProperty(ref this._sensorData, value); } } /// <summary> /// Gets or sets data missing message. /// </summary> public object ChartEmptyContent { get { return this._chartEmptyContent; } set { this.SetProperty(ref this._chartEmptyContent, value); } } /// <summary> /// Gets or sets chart header. /// </summary> public string ChartCaption { get { return this._caption; } set { this.SetProperty(ref this._caption, value); } } #endregion }}As you can see above, RadCartesianChart in "ContentTemplate" DataTemplate is bound to this ViewModel. And there is another ViewModel called UltrasonicSensorsViewModel which contain RadObservableCollection of SensorSignalChartViewModel. Please see it below:

Hi
I'm trying to data-bind the IsPinned-property of the GridViewRow to a value from my model.
After numerous unsuccessful tries, I tried setting the IsPinned property to true through a style (see below).
However, the row is not pinned, also the button does not reflect the Pinned state.
How can I set the IsPinned-property through a property of my model?
01.<telerik:RadGridView Grid.Row="2" ItemsSource="{Binding Path=CalculablePersons}" GroupRenderMode="Flat" PinnedRowsPosition="Top">02. <telerik:RadGridView.Resources>03. <Style TargetType="{x:Type telerik:GridViewRow}" BasedOn="{StaticResource {x:Type telerik:GridViewRow}}">04. <Setter Property="IsPinned" Value="True" />05. </Style>06. </telerik:RadGridView.Resources>07. 08. <telerik:RadGridView.Columns>09. <telerik:GridViewPinRowColumn />10. <telerik:GridViewDataColumn Header="Name" DataMemberBinding="{Binding Path=Name}" />11. </telerik:RadGridView.Columns>12.</telerik:RadGridView>

hello,
I want to present multiple legends on radMap, each legend item I want to present is actually a userControl that I build and it contains spectrum, numbers and some other buttons and options.
my final result is to have the map layer and above it a layer in witch allow the user drag and drop the legends all over the map (in order to place them wherever he wants)
so basically i need a layer that:
1. transparent
2. I want it not to block the layer below it
3. I want it to allow drag and drop
attached a png to show what i mean
I'm trying to use itemsControl in information layer in order to bind MapLeged to it but no success.. nothing presented on the map
this is my code in generally:
<telerik:RadMap>
<telerik:InformationLayer x:Name="informationLayer">
<ItemsControl itemsSource= " {Binding LayersProvider.Layers} "
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate......./>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<contentControl content={Binding LegendContext}"/>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</telerik:InformationLayer>
<telerik:VisualizationLayer......................./>
</telerik:RadMap>
<telerik:MapLegend x:Name="mapLegend"
Layer="{Binding informationLayer}" />
maybe you will have an idea for me.
thank you so match

Hi Telerik, We are facing two issues when we are using Stepline series. ISSUE 1 : When there is only one category / data point then chart is not drawing . We have such cases and we need solution or workaround for this case <telerik:StepLineSeries> <telerik:StepLineSeries.DataPoints> <telerik:CategoricalDataPoint Category="1" Value="1.0" /> <!--<telerik:CategoricalDataPoint Category="2" Value=1.1" /> <telerik:CategoricalDataPoint Category="3" Value="1.0" /> <telerik:CategoricalDataPoint Category="4" Value="1.1" />--> </telerik:StepLineSeries.DataPoints> </telerik:StepLineSeries>ISSUE 2 :We are using marked zone but marking falling in between and not from beginning so we used margin workaround from telerik to fix (Please see code from attached xaml.cs file) Before Shifting See image After Shifting See image BELOW CODE USED TO ALIGN MARGINint categoriesCount = this.horizontalAxis.Categories.Count();double categorySlotSize = this.chart.PlotAreaClip.Width * this.chart.Zoom.Width / categoriesCount; var margin = new Thickness(-(categorySlotSize / 2), 0, 0, 0); if (!margin.ToString().Contains("Infinity")) { this.chart.Annotations.Where(x => x is CartesianMarkedZoneAnnotation).ToList() .ForEach(m => { m.Margin = margin; }); }But we are facing issue when we zoom the chart.The marking going out of actual area.Please help to resolve it. After Zooming See Image ISSUE 3 : When we are using marking for last category then the marking done for half way only.Please help to draw until end (Need to support while zooming as well) <telerik:StepLineSeries> <telerik:StepLineSeries.DataPoints> <telerik:CategoricalDataPoint Category="1" Value="1.0" /> <telerik:CategoricalDataPoint Category="2" Value="1.1" /> <telerik:CategoricalDataPoint Category="3" Value="1.0" /> <telerik:CategoricalDataPoint Category="4" Value="1.1" /> </telerik:StepLineSeries.DataPoints> </telerik:StepLineSeries> <telerik:CartesianMarkedZoneAnnotation VerticalFrom="1.0" VerticalTo="1.1" HorizontalFrom="4" Fill="Red"/>

Hi,
I'm trying to use your cartesian 3D chart, I need to show a chart but with a line presentation (instead of surface or bar or point).
is that possible?
I'm attaching a screenshot of my needs with other 3d view component so maybe you can understand better what i'm talking about.

Hi,
I have the license for version 2011.1.405.40. And in this version, i am getting the Animation exception whenever i move the mouse over the timebar control. Apparently it is trying to access Hand property of Cursor and it is unable to animate it over the Border control. Following is my code:
<telerik:RadTimeBar x:Name="timeBar" Width="950" Height="250" PeriodStart="01-01-2011" PeriodEnd="01/01/2012" VisiblePeriodStart="01/01/2011" VisiblePeriodEnd="06/01/2011" SelectionStart="02/01/2011" SelectionEnd="03/01/2011" MinSelectionRange="28.00:00:00" MaxSelectionRange="31.00:00:00" IsSnapToIntervalEnabled="True"> <telerik:RadTimeBar.Intervals> <telerik:YearInterval/> <telerik:MonthInterval/> <telerik:WeekInterval/> <telerik:DayInterval/> <telerik:MinuteInterval IntervalSpans="1,10,15,30"/> <telerik:SecondInterval IntervalSpans="10,15,30"/> </telerik:RadTimeBar.Intervals> </telerik:RadTimeBar>
I have attached the image of exception as well. The newer version does not have this bug, but I cannot upgrade due to compatibility issues. I hope that there is a fix for this, disabling the animation or something like that.
Waiting for your early response. Thanks!
