Datagrid ItemsSource won't add the List

Question

Good Morning, I'm facing a very strange problem with a DataGrid in WPF. I'm trying to add the list of file inside a specific folder, but the grid remains blank. Could you please explain me why? That's my code:

private static readonly string _sharedFolder = Settings.GetShared();
private readonly DirectoryInfo _disF = new DirectoryInfo(_sharedFolder);

private void LoadRecipe_OnLoaded(object sender, RoutedEventArgs e)
{
    FileInfo[] _sFFiles = _sF.GetFiles("*.csv");
    List<string> filesList = new List<string>();
    foreach (FileInfo file in _sFFiles)
    {
        filesList.Add(file.Name);
    }

    Resources.MergedDictionaries.Add(Function.SetLanguageDictionary());
    Title = Function.GetTranslatedValue("LoadRecipe", Settings.GetLang());
    DatagridRecipes.ItemsSource = filesList;
    FoundRecipesLabel.Content = Function.GetTranslatedValue("FoundRecipes", Settings.GetLang());
    ButtonLoadRecipe.Content = Function.GetTranslatedValue("Load", Settings.GetLang());
}

I've also tried (inside the foreach) to print out the file.Name and I've got the right output. I don't really know why is not working. The only thing that I get every time is the file.Name.Length value.

Somebody can give me an hint?

Thank you in advance

EDIT

Here's the XAML:

<Grid>
    <Button x:Name="ButtonLoadRecipe" Content="Load" HorizontalAlignment="Stretch" Margin="10,0,10,10" VerticalAlignment="Bottom" Style="{DynamicResource SquareMetroButton}" Height="40" Click="ButtonLoadRecipe_Click"/>
    <DataGrid x:Name="DatagridRecipes" HorizontalAlignment="Left" Height="351" Margin="10,65,0,0" VerticalAlignment="Top" Width="274" AutoGenerateColumns="False" SelectionChanged="DatagridRecipes_SelectionChanged"/>
    <Label x:Name="FoundRecipesLabel" Content="RecipesFound" HorizontalAlignment="Left" Margin="10,10,0,0" VerticalAlignment="Top" FontSize="16" FontWeight="Bold"/>
    <Separator HorizontalAlignment="Left" Height="19" Margin="10,46,0,0" VerticalAlignment="Top" Width="274"/>
</Grid>

Answer 1

in How come my databinding is writing out the Length property? I answered where Length column comes from: it is auto-generated by DataGrid because columns auto-generation for properties is enabled by default and string has only property Length .

to get rid of "Length" column, set AutoGenerateColumns="False" and define <DataGrid.Columns> like in the linked question.

Binding string collection to DataGrid is a known "gotcha": WPF: Bind DataGrid to List<String> . DataGrid is supposed to be editable, but editing won't work with string items.

For your situation - display a list of string with possibility to select them - it is simpler to use ListBox instead of DataGrid
