Adding WPF ListView Items Dynamically

Question

I'm looking for examples or help to create a WPF listview of files.

<ListView Margin="10,10,0,13" Name="ListView1" HorizontalAlignment="Left"
         VerticalAlignment="Top" Width="194" Height="200">

I Load my files with this method :

    private void AddFiles_Click(object sender, RoutedEventArgs e)
    {
        OpenFileDialog ofd = new OpenFileDialog();
        ofd.Multiselect = true;

        if (ofd.ShowDialog() == true)
        {
            string[] filePath = ofd.FileNames;
            string[] safeFilePath = ofd.SafeFileNames;
        }
    }

What should I do now ?

ListView1.Items.Add(...) don't seems to work. In fact I can't find ListView1 from my cs code.

I found info here

do you want to show all files in a folder or only files selected by the user one by one? what is your end result? — Davide Piras

The problem is not about loading the files. My problem concern adding something to a listview. — Bastien Vandamme

I would recommend to use DataBinding for display items in ListView you should bind the ObservableColliction files; with your ListView ItemSource property and when you add or remove files in collection on the ListView items will be updated automaticaly

for example look at this article

Simple,

Store your file(name)s in a list (ObservableCollection) in your ViewModel
Databind the ListView.ItemSource to that collection
Add/Remove/Change files in the Collection, not in the Listview

If you're not using an explicit ViewModel, use your WindowClass as such.

as a quick and dirty way you can assign the collection of files directly to the ItemsSource property of the ListView

ListView1.ItemsSource = safeFilePath;

in the XAML you can add an ItemTemplate to customize the visualization of the single files
