可以設定或設定多線 TextBox 控制項中應該出現哪些捲動條。

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

ScrollBars

其中一個 ScrollBars 列舉值表示多線 TextBox 控制項是無滾動條、水平滾動條、垂直捲動條，或兩者皆有。 預設值為 ScrollBars.None。

例外狀況

InvalidEnumArgumentException

一個不在列舉有效值範圍內的值被賦予該屬性。

範例

以下程式碼範例建立一個多行 TextBox 控制項，並帶有垂直捲動條。 此範例也使用 AcceptsTab、 AcceptsReturn和 WordWrap 屬性，使多行 TextBox 控制在建立文字文件時非常有用。

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

若 WordWrap 屬性設為 true，無論屬性值 ScrollBars 為何，水平捲動條不會顯示。
