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[2].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[2].DefaultCellStyle.Alignment = DataGridViewContentAlignment.BottomRight;//文本向右对齐 //Search(detailID.Trim()); }
这个是开启线程
backgroundWorker1.RunWorkerAsync();
