        lblError.Text = "";
        if (e.CommandName == "Edit")
        {
            GridViewRow selectedRow = GVviewReminder.Rows[Convert.ToInt32(e.CommandArgument)];

            string ID = selectedRow.Cells[1].Text;

            Response.Redirect("edit_health_reminder.aspx?HealthReminderIsOpen=true&id=" + ID);
        }
    }

Answer 1

The error log says index out of range so look at collections.

GVviewReminder.Rows[Convert.ToInt32(e.CommandArgument)]

selectedRow.Cells[1].Text
