推荐答案

，您必须获取产生错误的文本框，您才能找到该框的父级，例如textbox.parent并进行类型转换来tabcontol并设置焦点..

这是一个粗略的想法，希望能解决您的问题并节省时间.

you must be getting the textbox which is producing the error, you whould be able to find the parent of that box like textbox.parent and typecast it to tabcontol and set the focus..

its a rough idea, wish it will solve your problem and save time.

您可以使用文本框上的选项卡前缀命名来根据控件的选项卡来区分控件.然后控件的父级可以选择该选项卡. 即

you may use the prefix naming of tab on textbox to diffrentiate between controls based on their tabs..secondly you can get the parent of the control then may select that tab..
i.e.

Control ctrl = txtBox.Parent
if ctrl is TabPage
{
  tbControl.SelectedTab = (TabPage) ctrl;
  txtBox.focus()
}

我认为代码应该像这样...

i think code should be some how like this...
