using Leadtools.Annotations.Automation; 
using Leadtools.Annotations.Engine; 
using Leadtools.Annotations.WinForms; 
 
public void AnnObject_Hyperlink() 
{ 
   double inch = 720.0; 
 
   // Get the container 
   AnnContainer container = _automation.Container; 
 
   // Add a red on green rectangle from 1in 1in to 2in 2in 
   AnnRectangleObject rectObj = new AnnRectangleObject(); 
   rectObj.Rect = LeadRectD.Create(1 * inch, 1 * inch, 1 * inch, 1 * inch); 
   rectObj.Stroke = AnnStroke.Create(AnnSolidColorBrush.Create("Red"), LeadLengthD.Create(1)); 
   rectObj.Fill = AnnSolidColorBrush.Create("Green"); 
   // Set its hyperlink 
   rectObj.Hyperlink = "https://www.leadtools.com"; 
   // Add it to the container 
   container.Children.Add(rectObj); 
 
   // Add a blue on yellow rectangle from 3in 3in to 4in 4in 
   rectObj = new AnnRectangleObject(); 
   rectObj.Rect = LeadRectD.Create(3 * inch, 3 * inch, 1 * inch, 1 * inch); 
   rectObj.Stroke = AnnStroke.Create(AnnSolidColorBrush.Create("Blue"), LeadLengthD.Create(1)); 
   rectObj.Fill = AnnSolidColorBrush.Create("Yellow"); 
   rectObj.Hyperlink = "https://www.leadtools.com/downloads/demos.htm"; 
   // Add it to the container 
   container.Children.Add(rectObj); 
 
   // Subscribe to the Run event of the automation 
   _automation.Run += _automation_Run; 
 
   // Switch to run mode 
   _automation.Manager.UserMode = AnnUserMode.Run; 
 
   Debug.WriteLine("Run mode, click on the rectangles to go to their hyperlinks"); 
} 
 
void _automation_Run(object sender, AnnRunDesignerEventArgs e) 
{ 
   // Check for status == End 
   if (e.OperationStatus == AnnDesignerOperationStatus.End) 
   { 
      // Get the annotation object 
      AnnObject annObj = e.Object; 
      // Get its hyperlink string 
      string hyperlink = annObj.Hyperlink; 
      // Browse to it 
      if (!String.IsNullOrEmpty(hyperlink)) 
      { 
         Process.Start(hyperlink); 
      }
