Tooltip not work in Annotation and PolarCustomAnnotation

[kity]

I have simple RadPolarChart and annotation collection.
I put tooltip, tooltip services but not work at all.
May it is becouse this is dynamic element figure and have diferent point position x,y ?
Or may be problem is becouse of standart .net framewrok behaiviars.

I try to use telerik tooltip behaviar but result is the same.
Here is my example:

<br>        <telerik:RadPolarChart x:Name="Myart"><br><br>            <telerik:RadPolarChart.Behaviors><br>                <telerik:ChartTooltipBehavior TriggerMode="Hold"    /><br>            </telerik:RadPolarChart.Behaviors><br><br>  <telerik:RadPolarChart.Annotations><br> <telerik:PolarCustomAnnotation PolarValue="{Binding Malue}" x:Name="Annotation1"<br>                                               RadialValue="{Binding Opt}"<br> telerik:RadToolTipService.ToolTipContent="Optimum vessel heading (Purple Ellipse)"<br>                               telerik:RadToolTipService.ToolTipContentTemplate="{StaticResource DataTemplateToolTip}"                                                                                                                                                                                                                                    <br>                               telerik:RadToolTipService.HorizontalOffset="10"<br>                               telerik:RadToolTipService.VerticalOffset="-10"      >                                          <br>

Hello,

Could you try setting the IsHitTestVisible to true and try again.

Hope that helps.

Hello,

According to your code snippet, you haven't set the IsHitTestVisible to true.

Below is an example of a PolarChart having annotation with IsHitTestVisible set to true and RadTooltipService used to set annotation's tooltip:

<telerik:RadPolarChart x:Name="polarChart" >
       <telerik:RadPolarChart.PolarAxis>
           <telerik:PolarAxis />
       </telerik:RadPolarChart.PolarAxis>
       <telerik:RadPolarChart.RadialAxis>
           <telerik:NumericRadialAxis />
       </telerik:RadPolarChart.RadialAxis>

       <telerik:RadPolarChart.Behaviors>
           <telerik:ChartTooltipBehavior />
       </telerik:RadPolarChart.Behaviors>

       <telerik:RadPolarChart.Series>
           <telerik:PolarPointSeries>
               <telerik:PolarPointSeries.DataPoints>
                   <telerik:PolarDataPoint Angle="30" Value="4"/>
                   <telerik:PolarDataPoint Angle="60" Value="4"/>
                   <telerik:PolarDataPoint Angle="90" Value="4"/>
               </telerik:PolarPointSeries.DataPoints>
           </telerik:PolarPointSeries>
       </telerik:RadPolarChart.Series>

       <telerik:RadPolarChart.Annotations >
           <telerik:PolarCustomAnnotation PolarValue="3"
                                          RadialValue="20"
                                          IsHitTestVisible="True">
               <telerik:PolarCustomAnnotation.Content>
                   <Ellipse Width="20" Height="20" Fill="Green" telerik:RadToolTipService.ToolTipContent="My custom tooltip content"/>
               </telerik:PolarCustomAnnotation.Content>

           </telerik:PolarCustomAnnotation>
       </telerik:RadPolarChart.Annotations>
   </telerik:RadPolarChart>

Attached is a picture of the end result.
