TextBoxBase.AcceptsTab 属性

定义

命名空间:

System.Windows.Forms

程序集:

System.Windows.Forms.dll

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。

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

public bool AcceptsTab { get; set; }

member this.AcceptsTab : bool with get, set

Public Property AcceptsTab As Boolean

属性值

Boolean

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。 默认值为 false。

示例

下面的代码示例使用 TextBox派生类创建具有垂直滚动条的多行 TextBox 控件。 此示例还使用AcceptsTab和AcceptsReturnWordWrap属性使多行文本框控件可用于创建文本文档。

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.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 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

注解

该 Multiline 属性还必须在 true 控件中获取 TAB 字符。

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