TextBox.AcceptsReturn 屬性

定義

取得或設定值,指出在多行 TextBox 控制項中按 ENTER 時,是否會在控制項中建立新行文字或啟動表單的預設按鈕。

public:
 property bool AcceptsReturn { bool get(); void set(bool value); };
public bool AcceptsReturn { get; set; }
member this.AcceptsReturn : bool with get, set
Public Property AcceptsReturn As Boolean

屬性值

Boolean

如果 ENTER 鍵在控制項的多行版本中建立新的文字行,則為 true,如果 ENTER 鍵啟動表單的預設按鈕,則為 false。 預設為 false

範例

下列程式碼範例會建立具有垂直捲動條的多行 TextBox 控制項。 這個範例會使用 AcceptsTabAcceptsReturnWordWrap 屬性,讓多行文字方塊控制項適用于建立文字檔。

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 to be entered 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!";
   }
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 to be entered 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!";
 }
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 to be entered 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!"
End Sub

備註

如果此屬性的值是 false ,使用者必須按 CTRL+ENTER,才能在多行 TextBox 控制項中建立新行。 如果表單沒有預設按鈕,則不論此屬性的值為何,ENTER 鍵一律會在控制項中建立新的文字行。
