I am using the sample from Telerik Demo to create pie chart, and register to .LayoutUpdate event, at which doing following:

        private void pieChart_LayoutUpdated(object sender, System.EventArgs e)
        {
            var paths = ChildrenOfTypeExtensions.ChildrenOfType<Path>(PieChart.Series[0]).ToList();
            if (paths.Count == 0)
                return;
            PieChart.LayoutUpdated -= pieChart_LayoutUpdated;
            foreach (var path in paths)
            {
                var dataPoint = path.Tag as PieDataPoint;
                if (dataPoint == null)
                    return;
                    path.MouseEnter += uiElement_MouseEnter;
                    path.MouseLeave += uiElement_MouseLeave;
            }
        }
        private void uiElement_MouseEnter(object sender, MouseEventArgs e)
        {
            var bar = (UIElement) sender;
            bar.Opacity = 0.5;
        }
        private void uiElement_MouseLeave(object sender, MouseEventArgs e)
        {
            var bar = (UIElement)sender;
            bar.Opacity = 1;
        } 

But I wanted more than just highlighting on pie "path", I want the associated label to be highlighted too.

Which at the moment, I am doing something like this:

        <Style x:Key="SlicerNameTextBoxStyle" TargetType="TextBlock">
            <Setter Property="Foreground" Value="{Binding DataItem, Converter={StaticResource SlicerToBrushConverter}}"></Setter>
            <Setter Property="FontWeight" Value="{Binding DataItem, Converter={StaticResource SlicerToNameConverter}}"></Setter>
            <Setter Property="FontFamily" Value="Segoe UI" />
            <Style.Triggers>
                <Trigger Property="IsMouseOver" Value="True">
                    <Setter Property="Background" Value="{StaticResource MouseOverBrush}"></Setter>
                </Trigger>
            </Style.Triggers>
        </Style>

                <telerik:PieSeries.LabelDefinitions>
                    <telerik:ChartSeriesLabelDefinition Margin="-4,0,0,0"
                                                        DefaultVisualStyle="{StaticResource SlicerNameTextBoxStyle}">
                        <telerik:ChartSeriesLabelDefinition.Template>
                            <DataTemplate>
                                <StackPanel>
                                    <TextBlock Text="{Binding DataItem.DisplayName}"
                                               HorizontalAlignment="Center"
                                               Style="{StaticResource SlicerNameTextBoxStyle}"
                                               MouseDown="SlicerPieLabel_OnMouseDown"/>
                                </StackPanel>
                            </DataTemplate>
                        </telerik:ChartSeriesLabelDefinition.Template>
                    </telerik:ChartSeriesLabelDefinition>
                </telerik:PieSeries.LabelDefinitions>

As you can see, the problem is that I can't connect the pie slice and label highlight together, and I duplicated the pie selection changed event.

Can you help me to provide a better solution here?

Thanks,

I have a child RadGridview contained in the row details of a master RadGridView defined through a data template .

Each row of the child RadGridview has an active checkbox bound to a viewmodel.  

If a child checkbox  is checked , as the master RadGridView is scrolled to hide the details of a row and then back again , that checkbox returns unchecked.

The viewmodel still shows the value as checked.

Any help would be appreciated.

RadScheduleView: clipping appointment name in Edit mode.

Hi, I need the appointment name in the schedule control to auto-expand to fit whatever the name of the appointment is. This is most troublesome in Edit mode, I get something like "This is the na..." - the rest of the name is clipped in the scheduler grid.

Please advise with a work-around.

Hello,

I'm following this document and are able to create the child gridview.

http://docs.telerik.com/devtools/wpf/controls/radgridview/hierarchical-gridview/basic-hierarchies

My need now is I want to have a double click event tied to the child gridview then get the parent row data (object).

Are there any sample codes or guidance?

Thanks,

Brew

A peculiar behavior we have found with the RadCalendar control:

We have a custom DayButtonStyleSelector set to an instance of a RadCalendar. This StyleSelector sets the Visibility of days that do not belong to the month displayed as Collapsed, instead of being grayed out as they normally would be.

Furthermore, we dynamically change the number of columns displayed dependent on the width available to the RadCalendar.

The StyleSelector works as intended when loading the Calendar and when increasing the column count, but when we reduce the column count by reducing the space available for the RadCalendar control, the last column seems to ignore the StyleSelector and displays the days of the following month in grey.

However, using Snoop we found out that the Style is applied - and consequently overridden by a locally set Visibility.

This only happens for the last column, and only when reducing the number of columns. Please see the attached screenshots (1.jpg shows the Calendar after loading, 2.jpg shows the calendar after expanding enough to display a third column, 3.jpg shows the calendar after reducing it back to 2 columns).

A code sample to illustrate this problem:

And the code behind (please excuse the VB.Net):

You can observe the problem described by changing the width of the window.

Hey,

I'm trying to create RadCartesianChart that on VerticalAxis and HorizontalAxis have DateTimeCategoricalAxis.

In the HorizontalAxis should be the date and in the VerticalAxis should be the Hours and Minutes.

Attached my view, I'm working on it over a week and still can't find the answer to this issue.

Hi,

I would like to know how we can have a horizontal scroll for the RadTimeline. The error is shown displayed on the line "<telerik:SelectionRange`1 End="1" Start="0"/>" which is part of the RadTimeline template. I have attached the screenshot of how the timeline looks currently.

Regards,
