Code In Gridview RowDatabound Not Working If Rowstate Is Alternate|Edit In ASP.NET Web Forms

In a gridview rowdatabound event I have this condition to check if rowstate is in edit mode:

if (e.Row.RowState == DataControlRowState.Edit) //row is in edit mode  
  {  
      TextBox actdaterec = (TextBox)e.Row.Cells[1].FindControl("txtDateRec");  
      actdaterec.Text = string.Empty;  
      TextBox cashRec = (TextBox)e.Row.Cells[2].FindControl("txtCashReceived");  
      cashRec.Text = string.Empty;  
  } 

The code above usually works if the rowstate is in edit mode, however on the succeeding rows the rowstate becomes Alternate|Edit. The code above does not work. So the solution would involve C# bitwise operator (&).
See the revised code below:

if ((e.Row.RowState & DataControlRowState.Edit) > 0) //row is in edit mode  
 {  
    TextBox actdaterec = (TextBox)e.Row.Cells[1].FindControl("txtDateRec");  
    actdaterec.Text = string.Empty;  
    TextBox cashRec = (TextBox)e.Row.Cells[2].FindControl("txtCashReceived");  
    cashRec.Text = string.Empty;  
 }  

The code will execute even if rowstate is Alternate|Edit. It will ignore the alternate value.
