We will take a look at the different use cases of the ListView and we will try out some of the architectural styles, wpf listview. Like wpf listview, I will provide different source code examples in the two most used. Jump to the corresponding sections by using the table of contents.

The Width and Height properties represent the width and the height of a ListView. The Name property represents the name of the control, which is a unique identifier of a control. The Margin property tells the location of a ListView on the parent control. The HorizontalAlignment and VerticalAlignment properties are used to set horizontal and vertical alignments.

The ListView control provides the infrastructure to display a set of data items in using a different layout or view. For example, a user may want to display data items in a table and also to sort its columns. The types referenced in this article are available in the Code reference section. The ListView derives from ListBox. Typically, its items are members of a data collection and are represented as ListViewItem objects. However, that child element can be any visual element. To specify a view mode for the content of a ListView control, you set the View property. One view mode that Windows Presentation Foundation WPF provides is GridView , which displays a collection of data items in a table that has customizable columns. The following example shows how to define a GridView for a ListView control that displays employee information. You can create a custom view mode by defining a class that inherits from the ViewBase class. The ViewBase class provides the infrastructure you need to create a custom view. You can also specify a Binding as part of a DataTemplate definition that you use to style the cells in a column.

One view mode that Windows Presentation Foundation WPF provides is GridViewwhich wpf listview a collection of data items in a table that has customizable columns. What we really need are some sort of columns and guess what, the ListView supports this out of the box, wpf listview, by just specifying the View property. In the end of this article, we saw how data binding works in ListView.

By using the GridView, you can get several columns of data in your ListView, much like you see it in Windows Explorer. Just to make sure that everyone can visualize it, we'll start off with a basic example:. So, we use the same User class as previously, for test data, which we then bind to the ListView. This is all the same as we saw in previous chapters, but as you can see from the screenshot, the layout is very different. This is the power of data binding - the same data, but presented in a completely different way, just by changing the markup. View property. We set it to a GridView, which is currently the only included view type in WPF you can easily create your own though!

In the last chapter we saw how we could group items in the WPF ListView by accessing the View instance of the ListView and then adding a group description. Applying sorting to a ListView is just as easy, and most of the process is exactly the same. Let's try a simple example where we sort the user objects by their age:. The XAML looks just like a previous example, where we simply have a couple of columns for displaying information about the user - nothing new here. In the Code-behind, we once again create a list of User objects, which we then assign as the ItemsSource of the ListView. Once we've done that, we use the ItemsSource property to get the CollectionView instance that the ListView automatically creates for us and which we can use to manipulate how the ListView shows our objects. With the view object in our hand, we add a new SortDescription to it, specifying that we want our list sorted by the Age property, in ascending order. As you can see from the screenshot, this works perfectly well - the list is sorted by age, instead of being in the same order as the items were added. As shown in the first example, sorting is very easy, but on the screenshot you'll see that Sammy comes before Donna. They have the same age, so in this case, WPF will just use the order in which they were added.
