In this article, I am going to discuss with you regarding the Drag and Drop functionality inside a Silverlight ListBox control. This article will also cover the Drag and Drop operation between two ListBox control. We will use here the Silvelright 4 Toolkit to implement the feature. 

Welcome to my 7th Beginners tutorial for Expression Blend & Silverlight.

This time we will be looking at Styling the Generated Content of a ListBox via the Additional Templates, & I will do my best to guide you through this.

Apart from describing the steps to style each of the controls for this particular theme, I've been trying to describe some of the techniques and knowledge that can be applied generally to any theme or style.

• In part 1 we covered creating style resources in a resource dictionary.

• In part 2 we covered editing control templates as part of a style, including states.

• In part 3 we knocked off a couple of the easier controls to style, although we added some extra elements to the control template.

In this post, we are going to dig down into a control that is made up of a collection of other controls: the ListBox. But we are going to begin by styling the other controls that make up the ListBox.

How to Style the Control Template of a ListBox in a small MVVM application. Discussing multiple Styles, nested Controls, Resource Dictionaries, Similar Control Templates (TreeView), Control Reuse & a few other tips...

One layout issue many folks run into in WPF and Silverlight is the problem of ListBox content not automatically sizing to the width of the ListBox.

Q: In Silverlight I want to display a list of complex bound criteria, which includes data, child data and photos for each item. The requirement is for the list to be displayed horizontally with only one item displayed at a time. Is this possible?

A: There are at least two approaches to solving this: a ListBox and a DataForm. In Silverlight 3, I wasn't able to scroll the ListBox incrementally, resulting in partially displayed items. In some cases this might be desirable, but the DataForm offers a clean incremental scroll. Figure 1 shows the DataForm solution. Both approaches use a DataTemplate that allows reuse of control layouts.

A customer recently asked how to implement a simple "grouped ListBox" experience in Silverlight (now available in desktop, mobile, and extra crispy flavor!), so I dashed off this sample to show one way that's pretty easy to work with.

This cool tutorial of Victor Gaudioso is about building a 3-column ListBox in Expression Blend.

Well, the project I was working on was a Silverlight project, not a WPF project, and the current release of Silverlight does not contain a WrapPanel. So now my clever solution was not a solution at all. After a bit more research, I found that the Silverlight Toolkit does have a WrapPanel. So, I was able to use that to make a three column Silverlight ListBox. Today, I am going to show you how to use the Silverlight Toolkit WrapPanel to create a three column ListBox.
