title: DataGridViewColumn.Frozen with mono 2.10
body: <p>I have a problem with Method <code>DataGridViewColumn.Frozen</code> with mono on Linux, and googling this problem doesn't helps me.</p>
  
  <p>I'm need to freeze couple of columns of <code>DataGridView</code> within C# mono application, and on Windows it's working as expected, but any time i copying my binary to Linux PC, method <code>Frozen</code> doesn't work at all.</p>
  
  <p>I have tried <code>Columns[index].Frozen</code> and <code>Columns[name].Frozen</code> both before and after filling the <code>DataGridView</code>.</p>
  
  <p>Is this a bug of my mono version, or i need some additional code to make this work?
  I'm using mono 2.10 (unfortunately, i cannot upgrade it) on SUSE Linux.</p>
  
  <h2>UPD</h2>
  
  <p>Made a simple application and tested it on mono 4.6.2: same with 2.10, method <code>Frozen</code> doesn't work.</p>
  
  <p>Code of testing app:</p>
  
  <pre><code>DataTable _tbl = new DataTable();
  _tbl.Columns.Add("Name", typeof(String));
  _tbl.Columns.Add("val1", typeof(String));
  _tbl.Columns.Add("val2", typeof(String));
  
  _tbl.Rows.Add("1", "val11", "val22");
  _tbl.Rows.Add("2", "val11", "val22");
  
  dgvVars.DataSource = _tbl;
  dgvVars.Columns["Name"].Frozen = true;
  dgvVars.Columns[0].Frozen = true;
  </code></pre>
