what is your exact purpose for creating dynamical row? To display some picture?
as I know it is easy to dynamially create the row, but not easy to maintainance. I have similar experience. My purpose of creating dynamical row is to insert a blank row without height below some special rows to highlight them, however, it will completely change after postback. My solution is changing the style of the row instead of inserting a new row.

C++

private void InsertSummaryRow(GridView gv,  int rowIndex,int colSpan, int HLfontSize)
 {

     //this is just an example of how to insert the dynamical row. HLfontSize is the font size of the label

     Label Summary0 = new Label();

    Summary0.Text = "Summary:";
     Summary0.Font.Size = HLfontSize;  Summary0.ForeColor = System.Drawing.Color.FromName("MediumBlue"); Summary0.Height = Unit.Parse("20px");

     GridViewRow tr = new GridViewRow(0, 0, DataControlRowType.EmptyDataRow, DataControlRowState.Normal);
     TableCell cel = new TableCell();
     cel.ColumnSpan = colSpan;
     cel.Style.Add("border-bottom", "blue 3px solid");  //style of the row
     cel.Style.Add("white-space", "nowrap"); //style of the row
     cel.Controls.Add(Summary0);
     tr.Cells.Add(cel);

     gv.Controls[0].Controls.AddAt(rowIndex, tr);

 }
