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);
