方法一：

设置属性：

Control.CheckForIllegalCrossThreadCalls = false;

开启一个新线程

Thread th = new Thread(() => Search(detailID.Trim()));
th.IsBackground = true;
th.Start();

public void Search(string detailID)
{
dataGridView1.DataSource =BLLBillConsume.BllGetClearMarketLog_detail(detailID);
dataGridView1.Columns[].DefaultCellStyle.Alignment = DataGridViewContentAlignment.BottomRight;//文本向右对齐
}

上面的方法不推荐，推荐以下方法：

拖一个组件backgroundWorker

设置属性：

backgroundWorker1.WorkerReportsProgress = true;
backgroundWorker1.WorkerSupportsCancellation = true;

执行用时较长的操作，

backgroundWorker1.CancellationPending是用来判断是否允许用户取消

private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
{
dtMain = BLLBillConsume.BllGetClearMarketLog_detail(detailID);
if (!backgroundWorker1.CancellationPending)
{//退出
backgroundWorker1.CancelAsync();
}
}

Thread.Sleep(100000);只是为了模拟界面卡死然后就显示查询到的数据

private void backgroundWorker1_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
dataGridView1.DataSource = dtMain;
dataGridView1.Columns[].DefaultCellStyle.Alignment = DataGridViewContentAlignment.BottomRight;//文本向右对齐
//Search(detailID.Trim());
}

这个是开启线程

backgroundWorker1.RunWorkerAsync();
