WinForm控件导航

Question

我想为用户提供通过键盘在WinForm控件上导航的选项。

我想浏览某些控件，而不是所有控件。
例如-在单选按钮之间导航并跳过同样以相同形式存在的按钮。

我将botton的TabStop属性设置为“ False”，但是在导航并到达按钮控件的索引时，按钮未聚焦，因为如上所述，我将TabStop设置为false，但是导航在最近的地点等待并且确实不继续。

有什么想法可以避免吗？

设计者代码：

    partial class Form1
{
    /// <summary>
    /// Designer variable used to keep track of non-visual components.
    /// </summary>
    private System.ComponentModel.IContainer components = null;

    /// <summary>
    /// Disposes resources used by the form.
    /// </summary>
    /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
    protected override void Dispose(bool disposing)
    {
        if (disposing) {
            if (components != null) {
                components.Dispose();
            }
        }
        base.Dispose(disposing);
    }

    /// <summary>
    /// This method is required for Windows Forms designer support.
    /// Do not change the method contents inside the source code editor. The Forms designer might
    /// not be able to load this method if it was changed manually.
    /// </summary>
    private void InitializeComponent()

如果您确实想在不按Tab键排序的情况下执行此操作，则可以使用此命令

  int gTabCounter = 0;     

        protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
        {
            if (keyData.Equals(Keys.ShiftKey | Keys.Shift)) //you can set any key you want
            {
                List<Control> controls = new List<Control>();
                controls.Add(button1);
                controls.Add(textBox1);                
                if (gTabCounter > 1) gTabCounter = 0;
                controls[gTabCounter].Focus();
                gTabCounter++;
            }
            return base.ProcessCmdKey(ref msg, keyData);
        }

根据如何：在Windows窗体上设置选项卡顺序 ：

设置控件的选项卡顺序

1. 在视图菜单上，单击制表符顺序。

   这将激活表单上的选项卡顺序选择模式。 每个控件的左上角都会出现一个数字（代表TabIndex属性）。

2. 依次单击控件以建立所需的选项卡顺序。

从选项卡顺序中删除控件

1. 在“属性”窗口中将控件的TabStop属性设置为false。 将TabStop属性设置为false的控件仍然保持其按Tab键顺序的位置，即使使用TAB键在控件之间循环时也会跳过该控件。

Answer 3

表单没有导航问题。 该窗体只有两个TabStop项-RadioButton组和Button。 由于Button的TabStop属性设置为false，因此实际上只有一个TabStop项-RadioButton组，即按Tab键似乎无效。

如果您向窗体添加一个或多个其他控件并尝试浏览该窗体，则此解释应该是很有意义的。

可以使用向上和向下箭头遍历RadioButton组。 它使用TabOrder属性来确定单选按钮的导航顺序。 考虑到表格内容，“ TabOrder”可能有点用词不当。
