Hi terinfire,

you can use SymbolElement to place it at specific coordinates and attach to XamMap's ElementClick. 

Another approach would be to use MapLayer's ValueTemplate and set its DataTemplate to Button. You will also need to create an attached property for page address since MapElement doesn't provide one.

In XAML:

<igMap:XamMap x:Name="xamMap1" ElementClick="xamMap1_ElementClick">
 <igMap:XamMap.Layers>
  <igMap:MapLayer x:Name="MapLayer" IsAutoWorldRect="True" >
   <igMap:MapLayer.Reader>
    <igMap:ShapeFileReader Uri="Shapefiles/usa/usa_st" DataMapping="Name,Caption=STATE_NAME"/>
   </igMap:MapLayer.Reader>            
  </igMap:MapLayer>

  <igMap:MapLayer x:Name="symbolLayer">
   <igMap:MapLayer.ValueTemplate>
    <DataTemplate>
     <Button Content="Click me" Click="Button_Click" />
    </DataTemplate>
   </igMap:MapLayer.ValueTemplate>
  </igMap:MapLayer>

 </igMap:XamMap.Layers>
</igMap:XamMap>

In code behind:

1. Create an attached dependency property to hold page's uri

 #region PageAddress

public Uri PageAddress
{
 get { return (Uri)GetValue(PageAddressProperty); }
 set { SetValue(PageAddressProperty, value); }
}

public static readonly DependencyProperty PageAddressProperty =
 DependencyProperty.RegisterAttached("PageAddress", typeof(Uri), typeof(ButtonSymbol),
   new PropertyMetadata(null));

#endregion

2. Add the button that will open a new page on click. The button is added at specific coordinates. Also set the page address.

var element = xamMap1.Layers[0].Elements.FindElement("Name", "Montana").ElementAt(0);

var origin = new Point(element.WorldRect.X + 0.5 * element.WorldRect.Width, element.WorldRect.Y + 0.5 * element.WorldRect.Height);
var symbolElement = new SymbolElement { SymbolOrigin = origin, SymbolType = MapSymbolType.None, SymbolSize = 10 };

symbolElement.SetValue(PageAddressProperty, new Uri("http://es.infragistics.com/"));

xamMap1.Layers[1].Elements.Add(symbolElement);

Rect worldRect = xamMap1.Layers[1].WorldRect;
worldRect.Union(symbolElement.WorldRect);
xamMap1.Layers[1].WorldRect = worldRect;

3. Handle the button click event

private void Button_Click(object sender, RoutedEventArgs e){           
 var button = (Button) sender;
 var element = (SymbolElement) (button.DataContext);
 var uri = (Uri)(element).GetValue(PageAddressProperty);

 HtmlPage.Window.Navigate(uri);           
}
