MORE INFORMATION

Steps to Reproduce the Behavior

1. Create a DataTable with computed column based on aggregate function.
2. Add rows to the DataTable and then call the AcceptChange method.

   DataSet dSet = new DataSet();
   DataTable DTable = new DataTable("Test"); 
   DTable.Columns.Add("Val1", typeof(int)); 
   DTable.Columns.Add("Total", typeof(int), "SUM(Val1)"); 
   DTable.Rows.Add(new object[]{2}); 
   DTable.AcceptChanges(); 
   DTable.Rows[0].Delete(); 
   try 
   { 
      DTable.Rows.Add(new object[]{4});
   } 
   catch(Exception e1 ) 
   { 
      System.Diagnostics.Debug.WriteLine(e1.ToString()); 
   }
