title: Not able to add a System.Windows.Controls.TextBox to groupbox controls in C#
body: <p>Is there any way to add a <code>System.Windows.Controls.TextBox</code> to <code>GroupBox</code> controls in C#?</p>
  
  <p>I tried the following but it doesn't show up in the groupbox:</p>
  
  <pre><code> public System.Windows.Controls.TextBox textBox6 = new System.Windows.Controls.TextBox();
   public System.Windows.Controls.TextBox textBox7 = new System.Windows.Controls.TextBox();
   public ElementHost sumtext = new ElementHost();
   public ElementHost loctext = new ElementHost();
  
   private void Form1_Load(object sender, EventArgs e)
      {
          textBox6.Name = "Summary";
          textBox7.Name = "Location";
  
          textBox6.FontFamily = new System.Windows.Media.FontFamily("Microsoft Sans Serif");
          textBox6.FontSize = 12;
          textBox6.SpellCheck.IsEnabled = true;
  
          textBox7.FontFamily = new System.Windows.Media.FontFamily("Microsoft Sans Serif");
          textBox7.FontSize = 12;
          textBox7.SpellCheck.IsEnabled = true;
  
          groupBox4.Controls.Add(sumtext);
          sumtext.Dock = DockStyle.None;
          sumtext.Width = 246;
          sumtext.Height = 35;
          sumtext.Child = textBox6;
          sumtext.Location = new Point(3, 33);
          sumtext.Visible = true;
          sumtext.Enabled = false;
          groupBox4.Controls.Add(sumtext);
  
          groupBox4.Controls.Add(loctext);
          loctext.Dock = DockStyle.None;
          loctext.Width = 246;
          loctext.Height = 35;
          loctext.Child = textBox7;
          loctext.Location = new Point(3, 90);
          loctext.Visible = true;
          loctext.Enabled = false;
  
          this.Controls.Add(sumtext);
          this.Controls.Add(loctext);
      }
  </code></pre>
  
  <p>I need to use <code>System.Windows.Controls.TextBox</code> rather than <code>Form.TextBox</code> as I need it for spell check.</p>
  
  <p>Any help would be greatly appreciated! </p>
