Adding a row in between of a gridview in asp.net deletes the last row

I am facing an issue in a gridview in ASP.NET when I dynamically add a new row to a pre-populated GridView

My Grid View consists of element of two types ( say A and B) which are pre-populated from the database

The code I have written first calculates the count of elements of Type A , then adds a new row as a "ROW Seperator" , between the elements of Row A and Row B. I write this bit of logic in the row data bound event of the grid view

My grid view consists of checkboxes for both elements of type A and Type B.

Now if I check the last element in the grid View , I realizied after putting a break point that the given element no longer exists in the gridView although it visually appears in the front end for the user to "check".

I belive this is something to do with the dynamic row separator I added to the gridView but I can't seem to understand why.

Below is my code.

    //Page Load
    protected void Page_Load(object sender, EventArgs e)
    {
        //Getting count of elements of type A and storing it in a global variable
        globalA_count= GetCount(dataset);
        gridView.DataBind();
    }
    // GRIDVIEW DATABOUND

    protected void gvAccessories_RowDataBound(object sender, GridViewRowEventArgs e)
{
    //DATA SET IS ALREADY SORTED SO THAT "A" ELEMNTS AND 'B" ELEMENTS ARE GROUPED TOGETHERE
    if (e.Row.Cells[4].Text == "B")
    {
        e.Row.BackColor = System.Drawing.Color.FromArgb(236, 236, 236);
    }
    /*** "localA_Count" is used as a counter to count "A" elements within   rowdatabound
       * globalA_count" holds the count of "A" elements already calculated
       *  when "localA_Count" equals "globalA_count",it means all 
        A type elements are already traversed**/
     else if (e.Row.Cells[4].Text == "A")
     {
         localA_Count++;
         if (localA_Count== globalA_count)
         {
             // ADD ROW SEPERATOR
             GridViewRow row = new GridViewRow(0, 0, DataControlRowType.DataRow, DataControlRowState.Insert);   
             row.CssClass = "StdGridHeader";
             TableCell cell1 = new TableCell();
             cell1.Text = "sample text"
             cell1.HorizontalAlign = HorizontalAlign.Center;
             cell1.ColumnSpan = 4;
             row.Cells.Add(cell1);
             ((GridView)sender).Controls[0].Controls.AddAt(globalA_count+ 1, row);
          }
    }

}

Are you adding code to correct event? Your gridview id is "gridview" but event is different gvAccessories_RowDataBound() ?
