How to set showduration for ChartViewSeries Tooltip

[Giorgio]

Hi telerik Team,

I want to make longer the duration of tool tip visibility in a piechart, I tried several solutions but nothing seems to work.

Settings the show duration in ChartTooltipBehavior I obtain another tooltip.

here is my xaml:

 

<telerikui:RadPieChart x:Name="telerikPieChart"

                       d:DataContext="{Binding Source={d:DesignInstance design:PieChartSeriesDC, IsDesignTimeCreatable=True}, Path=Series}">

    <telerikui:RadPieChart.Behaviors>

        <telerikcv:ChartTooltipBehavior ShowDuration="3600" />

    </telerikui:RadPieChart.Behaviors>

    <telerikui:RadPieChart.Series>

        <telerikcv:DoughnutSeries ItemsSource="{Binding Children}" ValueBinding="Value"

                                  DefaultSliceStyle="{StaticResource PieSliceStyle}" ShowLabels="True">

        </telerikcv:DoughnutSeries>

    </telerikui:RadPieChart.Series>

    <telerikui:RadPieChart.TooltipTemplate>

        <DataTemplate>

            <Border Background="Black" Opacity="0.9" CornerRadius="5" Height="Auto"

                    ToolTipService.ShowDuration="3600000">

                <StackPanel Margin="6">

                    <StackPanel Orientation="Vertical">

                        <TextBlock Foreground="White" Grid.Row="0" FontSize="13" HorizontalAlignment="Center" FontWeight="Bold" TextWrapping="Wrap">

                            <TextBlock.Text>

                                <MultiBinding StringFormat="{}{0}  {1:P2}">

                                    <Binding Path="DataItem.Label" />

                                    <Binding Path="DataItem.Percentage" />

                                </MultiBinding>

                            </TextBlock.Text>

                        </TextBlock>

                        <ListView Grid.Row="1" ItemsSource="{Binding DataItem.Children}" Height="Auto" Background="Transparent" BorderThickness="0" Focusable="False">

                            <ListView.ItemTemplate>

                                <DataTemplate>

                                    <Grid>

                                        <Grid.ColumnDefinitions>

                                            <ColumnDefinition/>

                                            <ColumnDefinition Width="5"/>

                                        <TextBlock Grid.Column="2"

                                            <TextBlock.Text>

                                                <!--<MultiBinding StringFormat="{}{0:0.00}M€({1:P2})" >-->

                                                </MultiBinding>

                                            </TextBlock.Text>

                                        </TextBlock>

How can I set the show duration on the right tooltip?

Thank,

Hello Giorgio,

Thank you for the code. I used it to test the reported issue but I wasn't able to reproduce a behavior where second tooltip occurs. Using the ShowDuration property is the way to adjust the tooltip's display duration. However, can you prepare an isolated project demonstrating the described behavior and send it over? This will allow me to test it locally and investigate what is causing the issue.

Thank you for any help you can provide.

Regards,
Martin
