title: Gridview making a column invisable
body: <p>Hi I have a grid view which is dynamically generated via C# using a DataSet. 
  I'm passing a row ID field (from the database) to the grid view, as this is required when a user clicks to edit a records. However I don't want the user to be able to view the column.
  I have tried the following but it doesn’t seem to work? Could anyone suggest a way to hide the column or a better way of attaching the information to the grid view row so it can be used at a later stage.
  c#</p>
  
  <pre><code>        DataColumn ColImplantCustomerDetailsID = new DataColumn();
          ColImplantCustomerDetailsID.ColumnName = "Implant ID";
          ColImplantCustomerDetailsID.DataType = typeof(int);
          ColImplantCustomerDetailsID.Visable = false; &lt;-- visable doens't work here.
  </code></pre>
