The Tree View Control

keywords:Silverlight; VS 2008; Visual Studio 2008; XAML; Silverlight 3.0;
Article Description:
The Tree View control is ideal for displaying hierarchical data. While there is a great deal you can do with this control, in its simplest form it is fairly straightforward to work with, once you grok the essential recursiveness it demands (well, requests strongly).
Comments:
Nice sample about how to bind hierarchical data to a Silverlight Toolkit treeview. A pity that the sample project is not available for downloading.

Enabling Validation in Silverlight 4 with IDataErrorInfo
Entry Date: Jan 2010 site: John Papa Rating:
keywords:Silverlight; Silverlight 3.0;
Article Description:
One of the new features of Silverlight 4 Beta is the addition of the IDataErrorInfo interface. In Silverlight 3 we throw exceptions when a property value is invalid. The IDataErrorInfo interface has been around in .NET but is new to Silverlight 4 beta. It allows you to invalidate property values without throwing exceptions.
Comments:

Interesting... validation mechanism changes on Silverlight 4, cleaner approach to validate (no more exceptions).

Simple Silverlight Uploader with Progress Bar using HttpRequest or WCF
Entry Date: Dec 2009 site: Integrated Web Systems Rating:
keywords:Silverlight; Web Services; Silverlight 3.0;
Article Description:
I thought I’d write a little bit about a simple Silverlight file uploader I’ve been playing with. I see a lot of postings out there asking how to do a file uploader that can show upload progress using Silverlight. There are a few issues to overcome like: how to you actually measure progress, and while using the HttpRequest, how do you update the UI from the worker thread? So this project will hopefully answer some of your questions.
Comments:

With Silverlight 3 you where able to make a file open dialog, ... now with Silverlight 4 you can even drag and drop files from your desktop... excellent scenario to let the user upload files to the server, but... How to make a nice file uploader?.

Excellent sample implemented in an asynchronous way, it let's you easily notifiy the progress on real time, and do not block the UI thread.

Quite useful, when you define dependency propertyies based on enums, you won't be able to define them in a declarative way, ... you will need to define a typeconverter to convert them from string to enum.

keywords:Silverlight; Silverlight 3.0;
Article Description:
One of the most useful yet little-known new features of Silverlight 3 is one that has nothing to do with UIs: a brand new networking stack called the client HTTP stack, the client networking stack, or simply the client stack.
Comments:

Quite useful to get detailed error description, when your service calls fails, instead of getting the nasty "not found" you will get all the exception info.

keywords:Silverlight; XAML;
Article Description:

The way that ToolTips are usually used is by setting the ToolTipService.ToolTip property to some text. This will display the text in a rather bland rectangle, without wrapping. Here are some ways to make your ToolTips more useful and nicer looking.
Comments:

If you have a long tooltip text in Silverlight it won't break it... ugly stuff, ... good news is that you can customize it and add a textblock including a wrap text.
