Get Content from a Label in ListBox.DataTemplate

I'm trying to get the Label.Content inside a ListBox.DataTemplate as described in title, my problem is that in all the ways I've tried all gave error, below is my code.

xaml:

<ListBox x:Name="UsersList" Margin="644,50,50,31.999" ItemsSource="{Binding}" Background="White">
            <ListBox.ItemTemplate>
                <DataTemplate>
                    <Grid Height="50" Width="654" MouseEnter="SetHashUser">
                        <Grid.RowDefinitions>
                            <RowDefinition/>
                            <RowDefinition/>
                            <RowDefinition/>
                        </Grid.RowDefinitions>
                        <Label x:Name="HashUser" Content="{Binding Path=USER_HASH}" Visibility="Collapsed"/>
                        <TextBlock x:Uid="RealAcessoUserDisplay" Text="{Binding Path=NOME}" Grid.RowSpan="1" Grid.Row="0" Background="#FFF0F0F0"/>
                        <TextBlock x:Uid="RealAcessoUserDisplay" Text="{Binding Path=NIVEL_ACESSO}" Grid.RowSpan="1" Grid.Row="1" Background="#FFF0F0F0"/>
                        <Menu Grid.RowSpan="1" Grid.Row="2">
                            <MenuItem Header="Ativar"/>
                            <MenuItem Header="Desativar"/>
                            <MenuItem Header="Detalhes" Click="ShowUser"/>
                            <MenuItem Header="Editar"/>
                        </Menu>
                    </Grid>
                </DataTemplate>
            </ListBox.ItemTemplate>
        </ListBox>

DB Connection C#

        private void Listtks()
    {
        SqlConnection con = new SqlConnection();
        con.ConnectionString = ConfigurationManager.ConnectionStrings["BellaContext"].ConnectionString;
        con.Open();
        SqlCommand cmd = new SqlCommand();
        cmd.CommandText = "SELECT USER_HASH,NOME,NIVEL_ACESSO FROM USUARIOS";
        cmd.Connection = con;
        SqlDataAdapter da = new SqlDataAdapter(cmd);
        DataTable dt = new DataTable();
        da.Fill(dt);

        UsersList.ItemsSource = dt.DefaultView;
    }

My goal is when clicking on an item in the list, the SelectedRow gets the User_Hash.Content.

Event:

    private void SetHashUser(object sender, MouseEventArgs e)
    {
        display.Content = UsersList.SelectedItem(HashUser.Content);
    }

Error:

Error:

error CS0103: The name "HashUser" does not exist in the current context
error CS1955: The non-callable member "Selector.SelectedItem" can not be used as 
a method.

ListBox SelectedItem is not a method. It is property which gives the selecteditem of the listbox. In this case the selecteditem will be DataRow since you bind DataTable to ListBox.

Assuming USER_HASH as string. Try below code.

private void SetHashUser(object sender, MouseEventArgs e)
    {
        var dataRow = UsersList.SelectedItem;
        display.Content = dataRow.Field<string>("USER_HASH ");
    }
