title: displaying listbox in grid
body: <p>This might be a stupid question, but i'm stuck doing it :(. I have a grid and have 3 columns. I have a textbox and a listbox in each of these 3 columns as shown:</p>
  
  <pre><code>&lt;Grid.ColumnDefinitions&gt;
                  &lt;ColumnDefinition Width="130"&gt;&lt;/ColumnDefinition&gt;
                  &lt;ColumnDefinition Width="380"&gt;&lt;/ColumnDefinition&gt;
                  &lt;ColumnDefinition Width="146"&gt;&lt;/ColumnDefinition&gt;
               &lt;/Grid.ColumnDefinitions&gt;
  
              &lt;Grid.RowDefinitions&gt;
                  &lt;RowDefinition Height="30"&gt;&lt;/RowDefinition&gt;
              &lt;/Grid.RowDefinitions&gt;
              &lt;StackPanel Grid.Column="0" Grid.Row="0"&gt;
                  &lt;TextBox Text="File Name" Height="30"&gt;&lt;/TextBox&gt;
              &lt;/StackPanel&gt;
              &lt;StackPanel Grid.Column="1" Grid.Row="0"&gt;
                  &lt;TextBox Text="File Path" Height="30"&gt;&lt;/TextBox&gt;
              &lt;/StackPanel&gt;
              &lt;StackPanel Grid.Column="2" Grid.Row="0"&gt;
                  &lt;TextBox Text="File Size" Height="30"&gt;&lt;/TextBox&gt;
              &lt;/StackPanel&gt;
  
              &lt;StackPanel Grid.Column="0"&gt;
                  &lt;ListBox Name="listbox_name" Margin="1,30" Height="276" /&gt;
               &lt;/StackPanel&gt;
              &lt;StackPanel Grid.Column="1"&gt;
                  &lt;ListBox Name="listbox_path" Margin="1,30" Height="276" /&gt;
              &lt;/StackPanel&gt;
              &lt;StackPanel Grid.Column="2"&gt;
                  &lt;ListBox Name="listbox_size" Margin="1,30" Height="276" /&gt;
              &lt;/StackPanel&gt;
  </code></pre>
  
  <p>and the code behind it:</p>
  
  <pre><code>public Window1()
          {
          InitializeComponent();
  
          list.Add("D:\\a\\hy");
          list.Add("D:\\a\\hy1");
          list.Sort();           
      }
  
      private void Window_Loaded(object sender, RoutedEventArgs e)
      {
          listbox_name.ItemsSource = list;
          grid1.Visibility = Visibility.Hidden;
      }
  
  
      private void button1_Click(object sender, RoutedEventArgs e)
      {
          grid1.Visibility = Visibility.Visible;
      }
  </code></pre>
  
  <p>But on the click of the button, im not able to see the listboxes, with the list displayed. Please guide me as to where im going wrong. Thanks!</p>
