ListView Column Width Auto

I wrote code in XAML - WPF Browser Application - Page , just one Listview and one button to add new data to the listview (from other file), I am trying to make the first column auto size itself when the button is pushed, I am using Visual Studio c# 2010.

I've used the following method in the code behind, but AutoResizeColumns won't be recognized and gives an error.

Unfortunately, none of the previously suggested solutions worked with me.

The Code Behind 

public partial class Page1 : Page, INotifyPropertyChanged
{

    public Page1()
    {

        InitializeComponent();
        this.DataContext = new Page1Model();

    }

    private void TestListe_SelectionChanged(object sender, SelectionChangedEventArgs e)
    {
    }

    public event PropertyChangedEventHandler PropertyChanged;

    private void Button1_Click(object sender, RoutedEventArgs e)

   {
        TestListe1.AutoResizeColumns(ColumnHeaderAutoResizeStyle.ColumnContent);
   }

}

XAML 

<Grid>

    <Grid.RowDefinitions>
        <RowDefinition Height="3*"/>
        <RowDefinition Height="1*"/>
    </Grid.RowDefinitions>
    <ListView Name="TestListe1"   Margin="68,22,421,8"  FontSize="12"  >

        <ListView.View>
            <GridView>
                <GridView.Columns>
                      <GridViewColumn Width="auto">                                <GridViewColumn.HeaderTemplate>
                            <DataTemplate>
                                <TextBlock Text="ST1" Margin="10,0,10,1"/>
                            </DataTemplate>
                        </GridViewColumn.HeaderTemplate>
                        <GridViewColumn.CellTemplate>
                            <DataTemplate>
                                <TextBlock Text="{Binding One}" />
                            </DataTemplate>
                        </GridViewColumn.CellTemplate>
                    </GridViewColumn>

                                        </GridView.Columns>
            </GridView>
        </ListView.View>
   </ListView>

    <Button Name="Button1" Grid.Row="1" Height="27" Width="95" Margin="262,24,444,74"  Click="Button1_Click" />

</Grid>

AutoResizeColumns is from the namespace System.Windows.Forms. I'm not sure if that will work with WPF or not. But you can set the width of the column to NAN to make it resize

In your XAML if you name your GridView as follows:

<GridView x:Name="dataGridView">

Then you could resize all columns with this

 foreach (GridViewColumn c in dataGridView.Columns)
 {
     c.Width = 0; //set it to no width
     c.Width = double.NaN; //resize it automatically
 }
