TextBox.ScrollBars 屬性

定義

命名空間:

System.Windows.Forms

組件:

System.Windows.Forms.dll

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

ScrollBars

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

InvalidEnumArgumentException

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 AcceptsTab 、 AcceptsReturn 和 WordWrap 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。
