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 following code snippet sets the name, height, and width of a ListView control. The code also sets horizontal alignment to left and vertical alignment to top.

We will take a look at the different use cases of the ListView and we will try out some of the architectural styles. Like always, I will provide different source code examples in the two most used. Jump to the corresponding sections by using the table of contents. When you are using the code behind based approach , jump there. I mean, you are pretty much on the right side, but what makes it different from like a DataGrid, or even a ListBox? This can be easily done in like different views or layouts, depending on your usecase. A ListViewItem iteself is — more or less — just another template-ish element, being a ContentControl. There you can see, that it actually inherits from the class ListBox. Those could then be displayed inside your ListView by specifying what should actually appear. The chart object could be composed from many different objects and therefore you would need to specify a bit further. To do so, we usually need to first have some kind of data to display. At this point, we will just create some hardcoded items, to see, how the ListView and its ListViewItems are created in the first place. Keep in mind, that we will do this and more in an MVVM manner, later — which is the preferred way for me personally. After that, we can add some sort of styling like padding, a width and alignments to that GroupBox, to make it look less bruised. The final, but first testing XAML code could therefore look like this:.

Those could then be displayed inside your ListView by specifying what should actually appear. When you are using the code behind based approach wpf listview, jump there. If you try to use the same view mode with more than one ListView control, wpf listview, an exception occurs.

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.

We've already done several different things with the ListView, like grouping and sorting, but another very useful ability is filtering. Obviously, you could just limit the items you add to the ListView in the first place, but often you would need to filter the ListView dynamically, in runtime, usually based on a user entered filter string. Luckily for us, the view mechanisms of the ListView also make it easy to do just that, like we saw it with sorting and grouping. Filtering is actually quite easy to do, so let's jump straight into an example, and then we'll discuss it afterwards:. In Code-behind, we start off by adding some User objects to the ListView, just like we did in previous examples. The interesting part happens in the last two lines of the constructor, where we obtain a reference to the CollectionView instance for the ListView and then assign a delegate to the Filter property. This delegate points to the function called UserFilter , which we have implemented just below.

Jump to the corresponding sections by using the table of contents. The second choice will be the CellTemplate property, which we'll use for this example:. The following code adds TextBox contents to the ListView items. Keep in mind, that we will do this and more in an MVVM manner, later — which is the preferred way for me personally. The third button will be for removing the selected item. We need a possibility, to get the currently selected item and delete it somehow. Customized views like GridView are derived from the ViewBase abstract class, which provides the tools to display data items represented as ListViewItem objects. We can pass a function, to let the command determine, if it can be executed. And we are only able to do so, if we have something to talk to. Note The types referenced in this article are available in the Code reference section.

Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. 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.

Note that this example doesn't define the DisplayMemberBinding because doing so takes precedence over CellTemplate. WPF Tutorial. This is all the same as we saw in previous chapters, but as you can see from the screenshot, the layout is very different. The final, but first testing XAML code could therefore look like this:. The Name property represents the name of the control, which is a unique identifier of a control. To be able to this all work, make sure, you set an appropriate ViewModel for your MainWindow. The Width and Height properties represent the width and the height of a ListView. Table of contents Exit focus mode. This browser is no longer supported. The ListView control provides the infrastructure to display a set of data items in using a different layout or view. If the selected item therefore the SelectedMusicArtist changes, we tell the command to refresh. Jump to the corresponding sections by using the table of contents. As you may see, I have set the name of the CheckBoxes using Name property. To avoid alignment issues between cells in a GridView , do not use the ItemContainerStyle to set properties or add content that affects the width of an item in a ListView.
