    Combo Box Selection Changed Event get automatically fired at Page Load.
    When the page loads, ComboBox Selection changed Event get automatically fired which causing unnecessory
    WCF service function call.

    Check out the Following Code:-
    XAML:
    <telerikInput:RadComboBox  Width="100"  Margin="2"  Height="20" x:Name="ddlMeasure"  SelectionChanged="ddlMeasure_SelectionChanged"  HorizontalAlignment="Center" VerticalAlignment="Top" >
     </telerikInput:RadComboBox>
    C# Code Behind:
    public CareProviderbyDiseasePopUp()
           {
               busyIndicator = new BusyIndicator();
               busyIndicator.Width = 300;
               busyIndicator.Height = 325;
               busyIndicator.HorizontalAlignment = HorizontalAlignment.Center;
               busyIndicator.VerticalAlignment = VerticalAlignment.Top;
               busyIndicator.Visibility = Visibility.Visible;
               isLoading(true);
               InitializeComponent();
               intAppUserId = App.Current.Resources.Contains("AppUserId") ? Convert.ToInt32(App.Current.Resources["AppUserId"]) : 0;
               intDiseaseId = App.Current.Resources.Contains("DiseaseId") ? Convert.ToInt32(App.Current.Resources["DiseaseId"]) : 0;
               intMeasureId = App.Current.Resources.Contains("MeasureId") ? Convert.ToInt32(App.Current.Resources["MeasureId"]) : 0;
               intTrendDiseaseID = App.Current.Resources.Contains("TrendDiseaseID") ? Convert.ToInt32(App.Current.Resources["TrendDiseaseID"]) : 0;
               LayoutRoot.Children.Add(busyIndicator);
               radChart.Visibility = Visibility.Collapsed;
               BindChart();
                
               // Combo Box Selection Changed Event Registered
               ddlMeasure.SelectionChanged+=new Telerik.Windows.Controls.SelectionChangedEventHandler(ddlMeasure_SelectionChanged);
           }
