title: C# - DatagidView show full header text
body: <p>I have a datagrid in my application. My datagridview columns have very long names and I would like that datagridview would show full text of the column header. I have tried change <code>AutoSizeColumnMode</code> property to <code>ColumnHeader</code>, but I do that then I wont be able to resize the columns, I wont be able to make the cell bigger or smaller.</p>
  
  <p>Wich properties should I change so that my datagridview shows full text on the columns?</p>
  
  <p>Help is very appreciated.</p>
