title: Problem with Anchor property of controls inside UserControl
body: <p>I've got this problem when creating a new custom UserControl. In details, I create a derived UserControl with a DataGridView that has Anchor property set to [Left, Top, Right, Bottom] so that the DataGridView can resize whenever the UserControl container's sizes change. But when the application runs, the result is not exactly expected. The DataGridView right- and bottom-edge always grow outside the UserControl border. To understand this issue, I have debugged and discovered that whenever a UserControl is created, its size is always default to [100, 100] despite we set it to [800, 600] or anything else. I think this is the cause of the problem. When we design the UserControl, we use a larger size but in runtime, its size is default to [100, 100] so the automatic calculation of Anchor property becomes unexpected. </p>
  
  <p>Can anyone give me some hint on how to solve this problem? I have one dirty solution but also sometimes malfunctions. My solution is that in UserControl's OnLoad event handler, I set the right and bottom-edge of child controls. This solution works fine for most of my custom UserControl but sometimes it makes me misunderstood. Sometimes the issue still happens. It makes me confused. </p>
  
  <p>Can anyone give a clear explanation and a complete solution of this issue?</p>
  
  <p>Thanks in advance</p>
