c# windows form Tab Order
提问by Sertan Pekel
I have a windows form in C# project that keeps Student Info. I caught the image:
我在 C# 项目中有一个 Windows 窗体，用于保存学生信息。我抓到了图像：
I want to add data with sequential order as follows but when I enter data to Surname textbox, TAB button jumps to E-Mail textbox, then Phone Number textbox and lastly to Date of Birth DateTimePicker.
我想按如下顺序添加数据，但是当我将数据输入到姓氏文本框时，TAB 按钮跳转到电子邮件文本框，然后是电话号码文本框，最后是出生日期 DateTimePicker。
I made all control's TabStop property "False" on the form except these textboxes. And I arranged their TabOrder via Properties Section as follows 0,1,2.. as I intented. But the order followed as I wrote above. Then I opened Tab Order function via "View" on menu strip.. I clicked all controls which I wanted to use in order, but no use. The form and Tab button act as before. I caught Tab Order function image below:
除了这些文本框，我在表单上设置了所有控件的 TabStop 属性“False”。我按照我的意图通过属性部分将它们的 TabOrder 安排为如下 0,1,2..。但是按照我上面写的顺序。然后我通过菜单条上的“查看”打开了标签顺序功能..我点击了我想按顺序使用的所有控件，但没有用。表单和 Tab 按钮的作用和以前一样。我在下面找到了 Tab Order 函数图像：
What shall I do now?
我现在该怎么办？

TabIndex is important for controls which are siblings of the same parent. However, if your TextBox and ComboBox controls are each inside different parents then their parent controls must have a the proper TabIndex.
TabIndex 对于属于同一父级的同级控件很重要。但是，如果您的 TextBox 和 ComboBox 控件分别位于不同的父控件中，则它们的父控件必须具有正确的 TabIndex。
In the Windows Forms Designer you can see which controls are children of which panels by bringing up the Document Outline. Go to View -> Other Windows -> Document Outline.
在 Windows 窗体设计器中，您可以通过调出文档大纲来查看哪些控件是哪些面板的子项。转到查看 -> 其他窗口 -> 文档大纲。
If each TextBox or ComboBox is directly inside a parent then its TabIndex doesn't matter, it can be 0. It's the parent (and possibly the parent's parent's) TabIndex which needs to be in order.
如果每个 TextBox 或 ComboBox 直接位于父级内部，则其 TabIndex 无关紧要，它可以为 0。它是父级（也可能是父级的父级）TabIndex 需要按顺序排列。
