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:

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?  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.

I have a datagrid with a select column.
I want to view RowDetails for selected row on the click of a button.
Can you help in implementing this using MVVM pattern?

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?
           
var chartArea = new ChartArea();
 chartArea.LegendName = "test";
             
 var pieSeries = new DataSeries
 {
     Definition = new PieSeriesDefinition
     {
         InteractivitySettings =
             {HoverScope = InteractivityScope.None,
              SelectionScope = InteractivityScope.Item,
               SelectionMode = ChartSelectionMode.Single
              }
     }
 };
             
 
pieSeries.Definition.ItemLabelFormat = "p";
pieSeries.Add( new DataPoint() { YValue = 0.215208267, LegendLabel = "Toyota" } );
pieSeries.Add( new DataPoint() { YValue = 0.192960612, LegendLabel = "General Motors" } );
pieSeries.Add( new DataPoint() { YValue = 0.151830229, LegendLabel = "Volkswagen" } );
pieSeries.Add( new DataPoint() { YValue = 0.125964366, LegendLabel = "Ford" } );
pieSeries.Add( new DataPoint() { YValue = 0.091152353, LegendLabel = "Honda" } );
pieSeries.Add( new DataPoint() { YValue = 0.079093251, LegendLabel = "Nissan" } );
pieSeries.Add( new DataPoint() { YValue = 0.079093251, LegendLabel = "PSA" } );
pieSeries.Add( new DataPoint() { YValue = 0.064697675, LegendLabel = "Hyundai" } );
             
chartArea.DataSeries.Add(pieSeries);
RadChart1.DefaultView.ChartLegend.UseAutoGeneratedItems = true;
RadChart1.DefaultView.ChartArea = chartArea;
RadChart1.DefaultView.ChartLegend.Header = "Legend test";

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.

Regards

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:

public partial class Example : UserControl
    {
        private bool initialized;
        private const string NonDbfDataField = "HugsPerCapita";
  
        public Example()
        {
            InitializeComponent();
            this.RadMap1.InitializeCompleted += new EventHandler(RadMap1_InitializeCompleted);
        }
  
        void RadMap1_InitializeCompleted(object sender, EventArgs e)
        {
            if (!this.initialized)
            {
                this.initialized = true;
                this.InformationLayer.Reader.PreviewReadCompleted += new PreviewReadShapesCompletedEventHandler(Reader_PreviewReadCompleted);
            }
        }
  
        private void Reader_PreviewReadCompleted(object sender, PreviewReadShapesCompletedEventArgs eventArgs)
        {
            if (eventArgs.Error == null)
            {
                foreach (MapShape shape in eventArgs.Items)
                {
                    this.SetAdditionalData(shape);
                }
            }
        }
  
        private void SetAdditionalData(MapShape shape)
        {
            ExtendedData extendedData = shape.ExtendedData;
            if (extendedData != null)
            {
                // add new property to ExtendedData  
                if (!extendedData.PropertySet.ContainsKey(NonDbfDataField))
                {
                    extendedData.PropertySet.RegisterProperty(NonDbfDataField, "", typeof(int), 0);
                }
  
                string country = (string)shape.ExtendedData.GetValue("ISO_2DIGIT");
                int additionalFieldValue = this.GetHugsByCountry(country);
  
                // assign value to new property  
                shape.ExtendedData.SetValue(NonDbfDataField, additionalFieldValue);
                  
            }
        }
  
        private int GetHugsByCountry(string stateName)
        {
            return 43 ; 
        }  
  
          
  
    }

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.

I added checkbox column using GridViewColumn in radgridview. I want this column to be checked by default for some rows when the view is loaded. How do I do this by iterating through the rows?

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.
