我有一个 datagridview 显示车间中所有汽车的列表。在注册号的右侧，是几列阶段。每辆车的每个阶段的持续时间都已估算，接下来我需要显示实际花费的时间。理想情况下，这需要一个实时计时器。
每个作业的每个阶段都可以处于活动状态、暂停或完成状态。
就数据库表而言，我有以下内容 -
工作详情
ID - PK Auto increment
JobID - Int (Joined to Jobs table)
PhaseID - String (joined to JobPhases table)
EstimatedTime - decimal
ActualTime decimal
Status int (EntryType - NotStarted, Active, Paused, Complete)
工作阶段
ID - PK String
Name - VarChar(150)
时间日志
ID int
JobID int
PhaseID string
UserID int
DateEntry datetime
EntryType int
通过条形码扫描用户 ID、作业编号、任务 ID 和操作（未开始、活动、暂停和完成）。然后，这会将作业设置为活动状态。
我可以通过将 JobDetail.ActualTime 添加到 TimeLog.LastEntry.DateEntry 来设置和获取所用时间。问题是我需要在每个单元格中将其显示为实时代码，或者至少大约 10 秒间隔刷新
我到目前为止的代码是 -
private void tstbCommand_Leave(object sender, EventArgs e)
{
User u = User.FromID(Convert.ToInt32(tstbUser.Text.TrimStart('U')));
Job j = Job.FromID(Convert.ToInt32(tstbJobNo.Text.TrimStart('E', 'N', 'K', 'J', 'C')));
JobDetail jd = JobDetail.JobDetailFromJobIDAndPhaseID(j.ID, tstbTaskID.Text.TrimStart('E', 'N', 'K', 'J', 'C', 'D'));
TimeLog log = new TimeLog();
switch (tstbCommand.Text)
{
case "CMDACTIVE":
if (jd.Status == EntryType.Active)
{
//Alert already active
lstAlerts.Items.Add("The scanned job is already active.");
}
else
{
//Ok to update status to active
jd.Status = EntryType.Active;
log.EntryType = jd.Status;
JobPhaseTimer timer = new JobPhaseTimer();
timer.UID = jd.ID + "_" + jd.PhaseID;
timer.JobDetailID = jd.ID;
timer.JobID = j.ID;
timer.PhaseID = jd.PhaseID;
timer.StartTime = DateTime.Now;
timer.Stopwatch.Start();
timer.Start();
timers.Add(timer.UID, timer);
lstAlerts.Items.Add("The job " + jd.JobID + " has been set to active by " + u.FullName + ".");
}
break;
case "CMDPAUSE":
if (jd.Status == EntryType.Paused)
{
lstAlerts.Items.Add("The scanned job is already paused.");
}
else
{
JobPhase phase = JobPhase.FromID(jd.PhaseID);
jd.Status = EntryType.Paused;
log.EntryType = jd.Status;
TimeLog lastEntry = TimeLog.GetLastTimeLogEntry(j.ID, jd.PhaseID);
lstAlerts.Items.Add(lastEntry.EntryType + ", " + lastEntry.DateEntry);
jd.ActualTime = Convert.ToDecimal(jd.ActualTime) + Convert.ToDecimal(DateTime.Now.Subtract(lastEntry.DateEntry).TotalHours);
lstAlerts.Items.Add("The job phase " + phase.Name + " for job " + jd.JobID + " has been paused by " + u.FullName + ".");
}
break;
case "CMDCOMPLETE":
if (jd.Status == EntryType.Complete)
{
lstAlerts.Items.Add("The scanned job is already completed.");
}
else
{
jd.Status = EntryType.Complete;
log.EntryType = jd.Status;
lstAlerts.Items.Add("The job " + jd.JobID + " has been completed by " + u.FullName + ".");
}
break;
case "CMDQC":
if (u.MergedRole.HasRight("workshop.QualityCheck"))
{
if (jd.Status == EntryType.QualityChecked)
{
lstAlerts.Items.Add("The scanned job has already been quality checked.");
}
else
{
jd.Status = EntryType.QualityChecked;
log.EntryType = jd.Status;
lstAlerts.Items.Add("The job " + jd.JobID + " has been quality checked by " + u.FullName + ".");
}
}
else
{
lstAlerts.Items.Add("You do not have sufficient rights to quality check.");
}
break;
}
log.JobID = j.ID;
log.UserID = u.ID;
log.PhaseID = jd.PhaseID;
log.EntryType = jd.Status;
jd.UpdateJobDetail(u.Username);
log.AddNewTimeLog();
tstbJobNo.Text = "";
tstbUser.Text = "";
tstbTaskID.Text = "";
tstbCommand.Text = "";
}
为了将数据保留在 datagridview 上，目前我在计时器滴答声上调用 LoadData() -
void LoadData()
{
foreach (JobPhaseTimer timer in timers.Values)
{
JobDetail jd = JobDetail.JobDetailFromJobIDAndPhaseID(timer.JobID, timer.PhaseID);
jd.ActualTime = jd.ActualTime + Convert.ToDecimal(timer.Stopwatch.ElapsedMilliseconds);
jd.UpdateJobDetail("Test");
}
dt = JobManager.GetTodaysJobs();
if (dataGridView1.InvokeRequired)
dataGridView1.Invoke(new MethodInvoker(delegate
{
//access picturebox here#
dt = JobManager.GetTodaysJobs();
dataGridView1.AutoGenerateColumns = false;
dataGridView1.DataSource = dt;
dataGridView1.AutoResizeColumns();
}));
else
{
//access picturebox here
dt = JobManager.GetTodaysJobs();
dataGridView1.AutoGenerateColumns = false;
dataGridView1.DataSource = dt;
dataGridView1.AutoResizeColumns();
}
}
最后，我必须根据 EstimatedTime/ActualTime 格式化单元格颜色。如果 ActualTime (Live) 低于 EstimatedTime - 绿色。如果 ActualTime 大于 EstimatedTime - Red，如果 Actualime 接近（逻辑尚未确定），则显示黄色。
关于如何实现上述目标的任何想法/想法？我以前没有做过实时数据网格！
