Hi

I have a RadPieChart with a Doughnut series:

   <telerik:RadPieChart x:Name="PieChart">
            <telerik:DoughnutSeries x:Name="PieSeries1" ValueBinding="Value" ItemsSource="{Binding Items}" InnerRadiusFactor="0.4" RadiusFactor="0.8" DefaultSliceStyle="{StaticResource PieSliceStyle}">
                <telerik:PieSeries.LabelDefinitions>
                    <telerik:ChartSeriesLabelDefinition Template="{StaticResource LabelTemplate1}"/>
                </telerik:PieSeries.LabelDefinitions>
            </telerik:DoughnutSeries>
        </telerik:RadPieChart>

This is the label template:

  <DataTemplate x:Key="LabelTemplate1">
            <TextBlock Foreground="#FFB6B6B6"
                       Text="{Binding Path=DataItem.Label}"
                       Visibility="{Binding Path=DataItem.Visibility}"
                       FontSize="18" FontFamily="Segoe UI" TextAlignment="Center" />
        </DataTemplate>

The data objects I bind to in the template implements “INotifyPropertyChanged” and the properties raise the “PropertyChanged” event when changed. This works fine elsewhere.

The labels gets their initial label text/visibility fine. But if I update the values - it is not reflected to the labels.

I bind to the data objects in the “DefaultSliceStyle” too and it works fine when updating.

Any ideas why – and is there an alternative solution?

Hello,

I have RadTimeBar

            <telerik:RadTimeBar x:Name="radTimeBar"
                            PeriodStart="{Binding StartDate}" 
                            PeriodEnd="{Binding EndDate}" 
                            VisiblePeriodStart="{Binding VisibleStartDate}" 
                            VisiblePeriodEnd="{Binding VisibleEndDate}"                            
                            SelectionStart="{Binding CurrentTime, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
                            SelectionChanged="radTimeBar_SelectionChanged"                            
                            ScrollMode="ScrollAndZoom">
                <telerik:RadTimeBar.Intervals>
                    <telerik:MinuteInterval />
                </telerik:RadTimeBar.Intervals>
            </telerik:RadTimeBar>

When I slide the slider thumb to the end the aplication is broken

I don't know how to catch the exception before the crashed

I attached a print screen of the exception

Thanks

I'm trying to have a checkbox as a column that fires an event when it is checked or unchecked. The current code does that, but the problem I am facing is that when the grid is loading, it is firing an event for each item in the grid before it displays. Is there a way around this?

                            <telerik:GridViewDataColumn Header="" DataMemberBinding="{Binding IsCheckedInModel, Mode=TwoWay}" >
                                <telerik:GridViewDataColumn.CellTemplate>
                                    <DataTemplate>
                                        <CheckBox IsChecked="{Binding IsCheckedInModel, Mode=TwoWay}" Checked="VarImportance_Checked" Unchecked="VarImportance_Checked"/>
                                    </DataTemplate>
                                </telerik:GridViewDataColumn.CellTemplate>
                            </telerik:GridViewDataColumn>

Thanks,

This may be more of a WPF question. I updated our app to support multiple maps on the screen. I want each map to share the items used for the VisualizationLayer. This seems to work for custom items, but not for MapShapeData items. I tried using a different collection for each map to hold the items, but it didn't help. Details:

Add PolygonData objects. They show up fine but when zooming, they don't scale. If I change to use two maps, everything works perfectly. If I switch back to one map, the objects again stop scaling when zooming.

If I replace the PolygonData with a custom object that holds a LocationCollection and apply a MapPolygonView to the object, everything works perfectly, even with just one map.

What is it about PolygonData that causes this not to work?

Using PolygonData with a VirtualizationSource also works.

Hello!

In our app we are using dynamicly generated shapes on theRadMap via map shapes. 

All shapes areimplimented as Datatemplates on map Information layers. And it all works ok, until we come to MapEllipse. 

An attempt tp bind MapEllipse location to the Location property of the model, Exception is thrown, beacuse Locatuion is mot a Dependency Property.

Is there any way to solve the prolem, excep implemening new calss, based on MapEllipse with custom DependencyProperty? 

Thank you

Hello!

I am trying to display a PDF file in the RadPdfViewer that is shown as having a white background in other PDF Viewer programs (SumatraPDF, Adobe Acrobat Reader, ...), but in the RadPdfViewer it shows a red background. Is this a bug or is my file broken somehow? Or am I missing a setting that changes this behavior?

Cheers

Hi

I want to implement the item zoom in and out in the listbox.Similar to the zoom of the Diagram.

I have a custom class that I'm adding to a VisualizationLayer. I'm using the following template to display it:

Works great. But I don't know how to get the ZIndex working. I tried adding my own ZIndex (that calls PropertyChanged), inheriting from ExtendedDataProvider, putting Canvas.ZIndex in the template but the z-order of the item never changes. If I use a normal PolygonData with the default template, the z-order updates.

Hello,

when I selected the RadPane on the right,the pinbutton has missed.When I selected another control ,the pinbutton display.

How to change the pinbutton to solve the problem?

Regards,

Guo
