Open A Link In New Browser Window In Lightswitch 2011

In this tutorial I will explain how to open a link in new browser window in lightswitch.

Software Requirement

Before you start reading this tutorial you should make sure that

Visual studio 2010 is installed on your machine.
Visual Studio 2010 service pack 1 is installed on your machine.
Microsoft Visual Studio Light switch 2011 is installed on your machine.

Prerequisite Knowledge

Before you go ahead, it is required that you should know

What is lightswitch?
How to create buttons?
What is Execute() method of button?
What is HTML DOM?
What is dispatcher and why we use it?
How to create lightswitch screens?

Assembly Required

For implementation, we need System.Windows.Browser assembly.

Namespace Required

For implementation, we need following namespaces

Microsoft.LightSwitch.Threading
System.Windows.Browser

What Is Htmlpage Class?

It allows manipulation of browser’s DOM.

Implementation

Dispatchers.Main.BeginInvoke(() = >{
	var uri = new Uri("http://google.com", UriKind.RelativeOrAbsolute);
	HtmlPage.Window.Navigate(uri, "_blank");
});

In line 1 we are executing the code inside the dispatcher object.

In line 3 we are initializing the Uri class from http://google.com.

In line 4 we are opening a link in a new browser window using Navigate() method.

Running The Code Without Dispatcher

The obvious question that comes in your mind is – Why we need dispatcher object. The dispatcher object runs the code on the main UI thread. If you run the code without dispatcher then you will get this error - This operation can only occur on the UI Thread.
