为什么表单挂在输入焦点？ [英] Why the form hang at inputs focus ?
问题描述
i有xtraform（管理分支），其中包含一些输入和gridview。
加载表单后，我可以关注任何输入（ex ： - CodeInput.Text）没有任何问题。但是当我点击 EditGridbtnREP 时，输入数据就会填满。
请注意： ad_branches之间存在关系桌子和许多其他桌子。
当我再次关注任何输入时，表格挂起，需要2-3分钟。回复。

我尝试了什么：
i创建新表单并逐个复制控件并且问题仍然存在
i尝试评论代码一个接一个，但同样的问题
What I have tried:
i created new form and copied the controls one by one and the problem still exist
i tried comment the codes one by one but the same issue
SplashScreenManager.CloseForm(false);
SplashScreenManager.ShowForm(this, typeof(waitForm), true, true, false);
try { SplashScreenManager.Default.SetWaitFormDescription(strings.Creating_basic_components); } catch { }
InitializeComponent();
mrsalesdbEntities dbContext = ConnectionTools.OpenConn();
try{ SplashScreenManager.Default.SetWaitFormDescription(strings.loading_branches_list); } catch { }
ad_branchesBindingSource.DataSource = dbContext.ad_branches.ToList();
try { SplashScreenManager.Default.SetWaitFormDescription(strings.LOADING_company_data); } catch { }
ad_company_dataBindingSource.DataSource = dbContext.ad_company_data.Local.ToBindingList();
try { SplashScreenManager.Default.SetWaitFormDescription(strings.loading_Countries_Cities); } catch { }
ad_countryBindingSource.DataSource = dbContext.ad_country.ToList();
ad_cityBindingSource.DataSource = dbContext.ad_city.ToList();
推荐答案
我试着逐一评论这些代码，但同样的问题
i tried comment the codes one by one but the same issue
继续评论。你在构造函数中加载了很多东西。你说问题是在点击之后：你也在摆弄鼠标。很多是泼水。加载数据输入字段的奇怪方式（与同步到数据源中的当前项目相比）。
我保证，在某些时候会出现没有问题（当你完成评论时）。
或者，你可以使用调试器。
Keep commenting. You're loading a lot of stuff in the constructor. You say the problem is after the "click": You're also fiddling with the mouse. Lot's of "splashing". Weird way of loading data entry fields (versus syncing to a current item in a DATA SOURCE).
I promise, at some point there will be "no issue" (when you finish commenting).
Or, you can "use the debugger".
