In this post, I will tell you how to create pop up notification in Silverlight. I will separate the kinds of notification into: Alert, Prompt and Confirm popup box.

There is a class called System.Windows.Browsers that comes with Silverlight. Also, there are lots of methods to create alert, prompt and confirm box using JavaScript. Let’s look further into each notification one by one:

1. Alert

HtmlPage.Window.Alert("Alert from Silverlight screen");

Same thing can be achieved using the Silverlight MessageBox. The only difference is that in case of MessageBox, you don't have the alert symbol. But at the same time with MessageBox you have the option to display appropriate title for the pop up.

MessageBox.Show("MessageBox for Silverlight", "AlertMessageBox", MessageBoxButton.OK)

2. Confirm

HtmlPage.Window.Confirm("Do you know how to call Alert from Silverlight");

The confirm method returns bool value, this can be used to perfrom further action depending upon if user clicks OK or Cancel button. Below code display how to handle the same.

bool isConfirmed = HtmlPage.Window.Confirm("Do you know how to call Alert from Silverlight");

if (isConfirmed)

 {

   //Perform some action;

 }
This thing can also be achieved using the Silverlight MessageBox. The only difference is that in case of MessageBox return type is not bool but Enum of type MessageBoxResult. Also the 3rd parameter which is of enum type MessageBoxButton should be MessageBoxButton.OkCancel

MessageBox.Show("MessageBox for Silverlight", "AlertMessageBox", MessageBoxButton.OKCancel);

MessageBoxResult isConfirmed = MessageBox.Show("MessageBox for Silverlight", "Alert MessageBox", MessageBoxButton.OKCancel);

if (isConfirmed == MessageBoxResult.OK)

 {

   //Perfrom some Action;

 }

3. Prompt

HtmlPage.Window.Prompt("whatis name of site?");

Prompt method returns string method. The input provided can be used to perform further action

string inputValue = HtmlPage.Window.Prompt("what is name of site?");

if (inputValue.Trim() == "Experts Comment")

 {

   //Perfrom some action;

 }
