[Solved] How to bind ShowLabels in ScatterSeriesDescriptor.Style

<telerik:RadCartesianChart.SeriesProvider>

<telerik:ChartSeriesProvider Source="{Binding CieDatums, Mode=OneWay}">

<telerik:ChartSeriesProvider.SeriesDescriptors>

<telerik:ScatterSeriesDescriptor ItemsSourcePath="Value" XValuePath="X" YValuePath="Y" CollectionIndex="0">

<telerik:ScatterSeriesDescriptor.Style>

<Style TargetType="telerik:ScatterPointSeries">

<Setter Property="RenderOptions" Value="{StaticResource renderOptions}" />

<Setter Property="ShowLabels" Value="{Binding IsShowLabel, Mode=OneWay}"/>

<Setter Property="PointSize" Value="5,5"/>

</Style>

</telerik:ScatterSeriesDescriptor.Style>

</telerik:ScatterSeriesDescriptor>

</telerik:ChartSeriesProvider.SeriesDescriptors>

I have a check box which allow user to choose whether to display the point Label or not. The Binding IsShowLabel is not working. How can i bind the check box's IsChecked to the ShowLabels property?

Overlay Series . . . ?

I'm a new chart user, testing out the trial to see if it'll meet our needs. So hopfully this is a simple question. I'm in a c# WPF MVVM application. I have a StackedBar series and a RanageBar series programatically defined and bound via my xaml. Right now the two different series show up side-by-side in the chart. I'd like them to basically be overlayed on top of one another. Is there an easy way yo do this? Thx

DayStartTime and DayEndTime have no effect in TimelineView

Hi,

Except for the first and the last day off the timeline range, the DayStartTime and DayEndTime properties have no effect in TimelineView.
This issue is known and approved here in your feedback portal, but I could not find any hint of a release date.

Is this feature on your roadmap for 2015?

This feature is vastly asked for among our customers and they often complain about the timeline view being quite useless as it is now.

UpdateCellValue fires for when any property changes

Hello,

I just noticed that all cells of a row are updated if any property of the ViewModel changes.
Is there any way to stop this?

In my opinion, there should be a dictionary which indicates which cells have to update if a certain property changes.

Tabbing inside a RadMenuItem

I have a RadDropDownButton whose DropDownContent is a RadContextMenu.

In the first RadMenuItem ("New Project") inside the RadContextMenu I have various input controls.

I can't get tabbing between these input controls to work at all. With focus on one textbox or combobox, pressing the tab key does nothing. (Before I set IsTabStop="false" on all the RadMenuItems, this would result in tabbing through the RadMenuItems, which I didn't want).

Here's the code:

<telerik:RadDropDownButton Grid.Column="0" HorizontalAlignment="Right" VerticalAlignment="Top" Margin="0,5,25,0" Content="Actions" Width="100">

<telerik:RadDropDownButton.DropDownContent>

Crash in RadCartesianChart

Hi,

I'm experiencing crash in my RadCartesianChart. I have a databound grid showing the source data, I also have a RadCartesianChart with a ScatterLineSeries showing a graphical representation of this data. The ScatterLineSeries I create and add to the chart in code.

When I delete rows from the grid, the points are also removed from the chart, as expected.

After I make certain changes, I wish to clear the chart and draw the series again, to do this I call RadCartesianChart.Series.Clear() and recreate the series once again. Once I've done this however, if I delete an entry in the grid I experience a crash with the error....

An unhandled exception of type 'System.ArgumentException' occurred in Telerik.Windows.Controls.Chart.dll

Additional information: The provided node does exist in this collection.

Am I clearing out the series correctly when I reset the chart?

I have produced a small test app to demonstrate this behaviour available on request.

Here is the stack trace.

RadListBox does not invoke DragDropCompleted Handler

I'm guessing this is yet another bug in the RadListBox event handeling:

Create a RadListBox and set it up for Drag and Drop, and then attach handlers for DragInitialized and DragDropCompleted.

Drag and Drop Items and observe:

1. Dragging item from one list box to another does both DragInitialized and DragDropCompleted (correct)
2. Dragging an item to an invalid target and dropping does both DragInitialized and DragDropCompleted (correct)
3. Dragging and item and pressing ESC to cancel also does both DragInitialized and DragDropCompleted (correct)

However...

4. Dragging and item to another position in the same listbox to rearrange only calls DragInitialized handler. The DragDropCompelted handler is never called. (BUG!)

This screen cast demonstrates: http://screencast.com/t/mx9yQx0EdtZx
