线程间操作无效: 从不是创建控件“XXX”的线程访问它。问题 路过的朋友帮忙看下

Question

网上的解决方案：http://blog.csdn.net/jumtre/article/details/44927271 1：设置 CheckForIllegalCrossThreadCalls false 2：委托   3：用BeginInvoke 或者异步线程 为什么我用了线程还是提示这个错误呢 不明白 看代码 void GetInstance_storeSelectChanged(object sender, StoreSelectChangedEventArgs e) { if (IsOk) return; var temp=frmMain.GetInstance.dialog.Entity;; if (temp == null || temp.Count == 0) return; var sourceno = temp.Aggregate("", (current1, xxx) => current1 + (xxx.sourceno + ",")).TrimEnd(','); Task.Factory.StartNew(() => { var matappList = Voion.Core.SqlClientFactory.Instance.Query("SELECT * FROM matapp_dl WHERE docno=@docno", new { docno = sourceno }); if (matappList == null || matappList.Count == 0) return; foreach (var tagetModel in matappList) { var outlist = new stotheroutlst_pro { zbid = tagetModel.zbid, keyno = tagetModel.zbid, code = tagetModel.proitemno, productno = tagetModel.productno, seqno = 0, proitemno = tagetModel.proitemno, appqty = 1, numb = 2, lostqty = tagetModel.lostqty, sheetsqty = 3, prosheetsqty = 4, needqty = tagetModel.needqty, needsheetqty = 5, outno = "a", active_id = 6, stock_id = 7, userid = User.Idno, inputdate = DateTime.Now, sizelost = 6, retqty = tagetModel.Waitretqty, appid = 100 }; Entity.StotherOutlstProList.Add(outlist); } bindingSource.ResetBindings(false); var thread = new Thread(() => { gridView1.RefreshData(); }); thread.Start(); }); IsOk = true; } 错误的意思是 不是在UI线程修改了这个控件 。 GetInstance_storeSelectChanged是注册事件回调函数  报错的地方  gridView1.RefreshData(); 我已经用线程里面就是一个委托 怎么还是这个 错误呢。 不明白

Answer 1

method(T c,Action action) where T:Control { 　　if(InvokeRequired) 　　{ 　　　　Invoke(new Action(()=>action(c)); 　　} 　　else 　　　　action(c); }   bindingSource.ResetBindings(false); method（gridView1，view=>view.RefreshData()）;
