Kevin,

The error in RowDatabound is at the first line in the code after I check if it's a DataRow. The Row Index is zero and the EntityList.Count is 4. That's why I don't understand the RowNotInTable error.

    protected void gvLots_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        mmGridView gv = (mmGridView)sender;
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            int count = (int)(LotLineItems.EntityList[e.Row.RowIndex].LCount == null ? 0 : LotLineItems.EntityList[e.Row.RowIndex].LCount);

As soon as I call the BO method that repopulates the EntityList, that's when the row_DataBound fires for the grid and I get the RowNotInTable error message.

>>OK, and which specific line in this handler method is causing the error? The line number is displayed in the stack trace, but I don't know which line it is in the code you sent.
