title: DockStyle Fill for RunTime Generated Controls
body: <p>I'm trying to do something very simple that is giving me huge problems in C# Winforms.  I have two group boxes on a TabPage.  One docked right and one docked bottom.  I also have a Chart on the page (System.Windows.Forms.DataVisualization.Charting).  This Chart is to Dock.Fill the remaining space on the page.</p>
  
  <p>I first encountered the problem of the chart hiding behind both group boxes and still dock filling the entire page.  However, I found I could solve this by using "BringToFront" (or reordering the Document Outline order) and then the Chart docked properly and didn't overlap any other controls on the page.</p>
  
  <p>However, I am trying to add a Chart to the page at runtime and it again fills the entire page and hides behind the other controls.  How can I go about making this work?</p>
  
  <p>EDIT:
  Forgot to mention, calling "BringToFront" will throw an exception "Width must be greater than 0px".</p>
  
  <pre><code>chart_TapChart = new Chart();
  chart_TapChart.Dock = DockStyle.Fill;
  chart_TapChart.BringToFront();
  GroupBox gp1 = new GroupBox();
  gp1.Dock = DockStyle.Right;
  GroupBox gp2 = new GroupBox();
  gp2.Dock = DockStyle.Bottom;
  this.Controls.Add(chart_TapChart);    &lt;--this refers to tabpage
  this.Controls.Add(gp1);
  this.Controls.Add(gp2);
  </code></pre>
