WPF Xaml hyperlink's RequestNavigate event handler not found

Question

I have a WPF user control with its code behind file containing the initialization stuff. I am using the user control as an activeX component inside a different application.  XAML for the control is constructed within the other application and is applied to the user control programatically.   Hyperlinks within the XAML are not working and I found that I need to add the RequestNavigate event handler to get the hyperlink working.   I have added the required event handler inside the code behind and added an x:Class attribute to XAML with the namespace and class name. I get an error message that the RequestNavigate event handler is not found.   'Windows.Forms.Integration.WpfControl' does not contain a definition for 'Hyperlink_RequestNavigate' and no extension method 'Hyperlink_RequestNavigate' accepting a first argument of type 'Windows.Forms.Integration.WpfControl' could be found (are you missing a using directive or an assembly reference?)    Can anyone please help?   Here is my code behind:   namespace  Windows.Forms.Integration   {        public  partial  class  WpfControl : UserControl       {            internal   const   string  PREFIX =  "WPFControl-" ;            private   string  mstrXamlFile, mstrXaml;            private   bool  mblnInitialized;            private   string  mstrUid;               private   static  IDictionary string , WpfControl> sobjWPFControls =  new  Dictionary string , WpfControl>(StringComparer.OrdinalIgnoreCase);            private   static  IDictionary string , ObjectInstance> sobjObjectInstances =  new  Dictionary string , ObjectInstance>(StringComparer.OrdinalIgnoreCase);               public   string  ErrorMessage {  get ;  set ; }               public   static   string  WpfControlAssemblyVersion {  get  {  return  AssemblyInfo.VersionNumber; } }            public  WpfControl()           {               InitializeComponent();               mstrUid = PREFIX + Guid.NewGuid().ToString();               sobjWPFControls.Add(mstrUid,  this );               InitializeXaml();                              mblnInitialized =  true ;               lblErrorMessage.Text = ErrorMessage;           }               public   void  Hyperlink_RequestNavigate( object  sender, RequestNavigateEventArgs e)           {               Process.Start( new  ProcessStartInfo(e.Uri.AbsoluteUri));               e.Handled =  true ;           }                       private   void  InitializeXaml()           {               System.Windows.UIElement objUIElement =  null ;               lblErrorMessage.Visible =  false ;                try                {                    if  (! string .IsNullOrEmpty(mstrXamlFile))                       mstrXaml = File.ReadAllText(mstrXamlFile);                    if  (! string .IsNullOrEmpty(mstrXaml))                       objUIElement = XamlReader.Parse(mstrXaml)  as  System.Windows.UIElement;               }                catch  (XamlParseException exc)               {                                  }                            }                       }             }   Here is a sample XAML:   UserControl             xmlns = "http://schemas.microsoft.com/winfx/2006/xaml/presentation"             xmlns:x = "http://schemas.microsoft.com/winfx/2006/xaml"             xmlns:mc = "http://schemas.openxmlformats.org/markup-compatibility/2006"             xmlns:d = "http://schemas.microsoft.com/expression/blend/2008"             xmlns:system = "clr-namespace:System;assembly=mscorlib"             xmlns:interactivity = "clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity"             xmlns:ti = "clr-namespace:Windows.Forms.Integration;assembly=Windows.Forms.Integration"             xmlns:inlineImage = "clr-namespace:Windows.Forms.Integration;assembly=Windows.Forms.Integration"             x:Class = "Windows.Forms.Integration.WpfControl"             mc:Ignorable = "d"             Background = "White" >         UserControl.Resources >             RadialGradientBrush…

Hi Akshay Thanks for your reply. You are right that I am trying to get hyperlinks to work from within WPF control. I am following the same approach that you have suggested. The problem that I am facing is with the x:Class attribute. I need to mention the fully qualified class name in which the event handler is present in order to get the RequestNavigate event handled. When the x:Class attribute is specified I am getting compile error that the handler is not present. Line 10 in my sample XAML has the x:Class attribute. Line 27 in the code behind contains the event handler.

By your Code i think you want to create a hyperlink in XAML form Just try thi XAML : Click here cs Code :
private void Hyperlink_RequestNavigate(object sender, RequestNavigateEventArgs e) { Process.Start(new ProcessStartInfo(e.Uri.AbsoluteUri)); e.Handled = true; }
