I'm trying to hide the item labels on my chart. There are 52 items on one chart, so the item labels hide the actual line on the chart. I can't figure out how to turn them off. The data is generated from the code-behind. Here is a snippet that shows how I am creating the chart data:
Is there a simple way to do this? Demo code would be most appreciated. I would prefer the option to do it either in the XAML or the code-behind, since I might want to set the default in the XAML but then change it in the code-behind.
SeriesMapping mySeries = new SeriesMapping();mySeries.LegendLabel = "Current Year Cash Balance";mySeries.SeriesDefinition = new SplineSeriesDefinition();mySeries.SeriesDefinition.Appearance.StrokeThickness = 3;mySeries.ItemMappings.Add(new ItemMapping("CashBalance", DataPointMember.YValue));mySeries.ItemMappings.Add(new ItemMapping("Week", DataPointMember.XCategory));secondaryChart.SeriesMappings.Add(mySeries);secondaryChart.DefaultSeriesDefinition.ShowItemLabels = false;secondaryChart.ItemsSource = cashBalanceData.Tables["currentCashBalance"];Is there a simple way to do this?

I need to generate graphs on the fly and only when I receive the response will I know what type of graph to generate.
I have been trying for about a hour and cannot figure it out. What am I doing wrong? The legend shows the title, but it does not show the legend label that has been associated with each datapoint. Why?
What am I missing?

Its a defect in RadComboBox.
1) Create an application
2) Add RadComboBox in a window
3) in Code file just add one RadComboBoxItem to RadComboBox
4) Override the FontSize property in style something like
<Style TargetType="telerik:RadComboBox">
<Setter Property="FontFamily" Value="{x:Static ui:DefaultStyle.APP_FONT_FAMILY}"/>
<Setter Property="FontSize" Value="10.5"/>
<Setter Property="Height" Value="{x:Static ui:DefaultStyle.COMBO_BOX_HEIGHT}"/>
<Setter Property="telerik:StyleManager.Theme" Value="{x:Static ui:DefaultStyle.APP_THEME}"/>
</Style>
5) Run the application
6) click on radcombobox . Initially item looks blurred. And in few second it gets normal.
It happen only when u have one RadComboBoxItem.

The example code uses a generated dbf file, but I need to get data at runtime based, for example "hugs per captia".
I get NaN in the legend when I tried the following code:

Hello All,
I like the way the default control in RadGridView works - AKA Telerik.Windows.Controls.GridView.FilteringControl. However, I want to change one behavior; the application of the filter. Basicly, I want to intercept the filter specified by the user and interpret it myself. This way I can customize the behavior and keep the look and feel. Can anyone advise me how to do this?

I'm looking for a way to detect if an appointment within the schedule view is being edited due to the user dragging the entire appointment.
How do I detect when the user is dragging an appointment (the whole thing, as opposed to dragging one of the appointment's end points)?
Thanks for your time.

In the included code sample, here, if a row has its rowdetails open then scrolling becomes almost impossible. This is because the vertical scroll bar always wants to snap back to a given place.
For instance, scroll to the bottom of the list, open the details, and try to scroll up.
I did notice when creating this that the tab control has something to do with the problem. Without the tab control, scrolling is slow, but not freaky.
