PasswordTextBox for Silverlight 2 Beta 2

The standard TextBox control that is built into Silverlight 2 Beta 2 is a bit lacking and is missing alot of features that we have become accustomed to in a TextBox. One of those features is being able to mask the characters being displayed when its used to accept passwords. Here's a small PasswordTextBox control I built that does just that; it masks the characters from being displayed so you can accept passwords like you're used to. Update 6/7/2008 - I just tested this w... [More]

Working with HTML DOM in Silverlight 2 Beta 1 using the Bridge Pattern

Working with the HTML DOM in Silverlight 2 Beta 1 is rather simple and easy to do. However, to my surprise it's a similar experience to working the the HTML DOM from within JavaScript; you have to know the name of the properties to get/set and you don't have the luxury of compile time checking or intellisense. Here an example of creating a new DIV element and setting some of it's properties: [code:c#] HtmlElement myDiv = HtmlPage.Document.CreateElement("div&quo... [More]

I'm a little puzzled as to why they would have left this out, but I imagine MessageBox's are handled very differently in different Operating Systems.

It's not a major feature, but one that is used quite often when developing desktop ... [More]

Silverlight: Anatomy of an .XAP file

Silverlight 2 Beta 1 just came out this morning, so I started checking it out immediately. I installed the Silverlight Tools for Visual Studio and noticed that when a Silverlight Application is compiled a .xap file is created that contains the application. But, what exactly is a .xap file, and what exaclty is in there? What is an .xap file? A .xap file is basically a compiled Silverlight application. The file is actually a .zip file that contains all the files necessary for the application. ... [More]
