I am in the process of upgrading a project from 2008.3 to 2009.2 and I noticed that a page was breaking due to InitializeRow firing twice for every row.  The cause turned out to be that I was setting footer text after setting the data source, so I switched the order and it solved my problem.

Has anyone else seen this, and do you know if it's a bug or by design?  It's definitely a change from how 8.3 worked.

Example snippets:

           //version 1 - if this is in page_load, all rows get initialized twice.

            grid1.DataSource = data;

            grid1.Columns["Annual_Budget"].Footer.Text = String.Format("{0:C}", Convert.ToDecimal(data.Compute("Sum([Annual_Budget])", "")));

           //version 2 - if this is in page_load, all rows get initialized once.

           if (data.Rows.Count > 0)

           {

                 grid1.Columns["Annual_Budget"].Footer.Text = String.Format("{0:C}",               Convert.ToDecimal(data.Compute("Sum([Annual_Budget])", "")));

           }

            grid1.DataSource = data;
