TextBoxBase.AcceptsTab 属性

获取或设置一个值，该值指示在多行文本框控件中按 Tab 键时，是否在控件中键入一个 Tab 字符，而不是按选项卡的顺序将焦点移动到下一个控件。

**命名空间:**System.Windows.Forms
**程序集:**System.Windows.Forms（在 system.windows.forms.dll 中）

语法

声明
Public Property AcceptsTab As Boolean
用法
Dim instance As TextBoxBase
Dim value As Boolean

value = instance.AcceptsTab

instance.AcceptsTab = value

public bool AcceptsTab { get; set; }

public:
property bool AcceptsTab {
    bool get ();
    void set (bool value);
}

/** @property */
public boolean get_AcceptsTab ()

/** @property */
public void set_AcceptsTab (boolean value)

public function get AcceptsTab () : boolean

public function set AcceptsTab (value : boolean)

属性值

如果用户可以使用 Tab 键在多行文本框控件中输入 Tab 字符，则为 true；如果按 Tab 键移动焦点，则为 false。默认为 false。

备注

如果将 AcceptsTab 属性设置为 true，则用户必须按 Ctrl+Tab 键将焦点移动到 Tab 键顺序中的下一个控件。

示例

下面的代码示例使用派生类 TextBox 来创建一个带垂直滚动条的多行 TextBox 控件。此示例还使用 AcceptsTab、AcceptsReturn 和 WordWrap 属性来使多行文本框控件可用于创建文本文档。

Public Sub CreateMyMultilineTextBox()
    ' Create an instance of a TextBox control.
    Dim textBox1 As New TextBox()
    
    ' Set the Multiline property to true.
    textBox1.Multiline = True
    ' Add vertical scroll bars to the TextBox control.
    textBox1.ScrollBars = ScrollBars.Vertical
    ' Allow the RETURN key in the TextBox control.
    textBox1.AcceptsReturn = True
    ' Allow the TAB key to be entered in the TextBox control.
    textBox1.AcceptsTab = True
    ' Set WordWrap to true to allow text to wrap to the next line.
    textBox1.WordWrap = True
    ' Set the default text of the control.
    textBox1.Text = "Welcome!" & Environment.NewLine & "Second Line"
End Sub

public void CreateMyMultilineTextBox()
 {
    // Create an instance of a TextBox control.
    TextBox textBox1 = new TextBox();
    
    // Set the Multiline property to true.
    textBox1.Multiline = true;
    // Add vertical scroll bars to the TextBox control.
    textBox1.ScrollBars = ScrollBars.Vertical;
    // Allow the RETURN key in the TextBox control.
    textBox1.AcceptsReturn = true;
    // Allow the TAB key to be entered in the TextBox control.
    textBox1.AcceptsTab = true;
    // Set WordWrap to true to allow text to wrap to the next line.
    textBox1.WordWrap = true;
    // Set the default text of the control.
    textBox1.Text = "Welcome!" + Environment.NewLine + "Second Line";
 }

public:
   void CreateMyMultilineTextBox()
   {
      // Create an instance of a TextBox control.
      TextBox^ textBox1 = gcnew TextBox;
      
      // Set the Multiline property to true.
      textBox1->Multiline = true;
      // Add vertical scroll bars to the TextBox control.
      textBox1->ScrollBars = ScrollBars::Vertical;
      // Allow the RETURN key in the TextBox control.
      textBox1->AcceptsReturn = true;
      // Allow the TAB key to be entered in the TextBox control.
      textBox1->AcceptsTab = true;
      // Set WordWrap to true to allow text to wrap to the next line.
      textBox1->WordWrap = true;
      // Set the default text of the control.
      textBox1->Text = "Welcome!" + Environment::NewLine + "Second Line";
   }

public void CreateMyMultilineTextBox()
{
    // Create an instance of a TextBox control.
    TextBox textBox1 = new TextBox();
    // Set the Multiline property to true.
    textBox1.set_Multiline(true);
    // Add vertical scroll bars to the TextBox control.
    textBox1.set_ScrollBars(ScrollBars.Vertical);
    // Allow the RETURN key in the TextBox control.
    textBox1.set_AcceptsReturn(true);
    // Allow the TAB key to be entered in the TextBox control.
    textBox1.set_AcceptsTab(true);
    // Set WordWrap to true to allow text to wrap to the next line.
    textBox1.set_WordWrap(true);
    // Set the default text of the control.
    textBox1.set_Text("Welcome!" + Environment.get_NewLine()
        + "Second Line");
} //CreateMyMultilineTextBox
