title: Add Row Values to DataTable Having AutoIncreamented DataColumn
body: <p>I want to add a row in a DataTable having a Data Column which has an auto Increament Property. </p>
  
  <pre><code>DataTable tblproduct = new DataTable();
  
  DataColumn CartItemId = new DataColumn();
  CartItemId.ColumnName = "CartItemId";
  CartItemId.DataType = System.Type.GetType("System.Int32");
  CartItemId.AutoIncrement = true;
  CartItemId.AutoIncrementSeed = 1;
  CartItemId.AutoIncrementStep = 1;
  CartItemId.ReadOnly = true;
  CartItemId.Unique = true;
  
  tblproduct.Columns.Add(CartItemId);
  tblproduct.Columns.Add("CampaignId", typeof(int));
  tblproduct.Columns.Add("SubCatId", typeof(int));
  tblproduct.Columns.Add("Size", typeof(string));
  tblproduct.Columns.Add("Qty", typeof(int));
  
  tblproduct.Rows.Add(3, 345,"Hello", 1);
  tblproduct.Rows.Add(5, 3455,"Hecfghhgdfllo", 8);
  </code></pre>
  
  <p>I don't want to insert the values in Autoincreamented column. It should be Autogenerated value but above code didn't work for me.</p>
