TextBox.ScrollBars 屬性

定義

取得或設定在多行 TextBox 控制項中應該顯示的捲軸。

public:
 property System::Windows::Forms::ScrollBars ScrollBars { System::Windows::Forms::ScrollBars get(); void set(System::Windows::Forms::ScrollBars value); };
public System.Windows.Forms.ScrollBars ScrollBars { get; set; }
member this.ScrollBars : System.Windows.Forms.ScrollBars with get, set
Public Property ScrollBars As ScrollBars

屬性值

其中一個 ScrollBars 列舉值,指出多行 TextBox 控制項是顯示為沒有捲軸、有水平捲軸、有垂直捲軸,還是兩者都有。 預設為 ScrollBars.None

例外狀況

不在列舉型別 (Enumeration) 有效值範圍內的值會指派給這個屬性。

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。 這個範例也會使用 AcceptsTabAcceptsReturnWordWrap 屬性,讓多行 TextBox 控制項可用於建立文字檔。

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 TAB 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 TAB 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 TAB 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 WordWrap 屬性設定 true 為 ,則不會顯示水準捲軸,不論 屬性的值 ScrollBars 為何。
