GridView CommandField Button is not firing

gv1_RowEditing event gets fired when CommandField button gets clicked.I am rebinding the data here.
 protected void gv1_RowEditing(object sender, GridViewEditEventArgs e)
        {
           
            gv1.EditIndex = e.NewEditIndex;
            BindGrid();
        }

I am using the RowDataBound event in GridView.In the GridView RowDataBound event I am enabling CommandField edit button based on user authorization.
   protected void gv1_RowDatabound(object sender, GridViewRowEventArgs e)
        {
            GridViewRow gRow = e.Row;    
            if (gRow.RowType == DataControlRowType.DataRow)
            {
                DataRowView drv = (DataRowView)e.Row.DataItem;
             
                if (IsAuthorized)
                {
                    gRow.Cells[2].Enabled = true;
                }

                else
                {
                    gRow.Cells[2].Enabled = false;
                }

            }


        }

The GridView RowDataBound event is firing each time button is clicked(I am rebinding the Grid in each button click)
How to make RowDataBound event get fired only on Page_Load if (!PostBack) condition satisfied.

Is it because GridView RowDataBound event code the CommandField Update and Cancel buttons are not showing when CommandFiled clicked.

Thanks

try removing your bindgrid() function from the gv1_RowEditing event.

I removed the bindgrid() function from the gv1_RowEditing event.  Then it is not showing the
Update and Cancel buttons and also the controls not turned into editable Text Boxes.
Thanks
