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。Gets or sets which scroll bars should appear in a multiline TextBox control.

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。One of the ScrollBars enumeration values that indicates whether a multiline TextBox control appears with no scroll bars, a horizontal scroll bar, a vertical scroll bar, or both. 預設為 ScrollBars.NoneThe default is 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。A value that is not within the range of valid values for the enumeration was assigned to the property.

範例

下列程式碼範例會建立 TextBox 具有垂直捲動條的多行控制項。The following code example creates a multiline TextBox control with vertical scroll bars. 這個範例也會使用 AcceptsTabAcceptsReturnWordWrap 屬性,讓多行 TextBox 控制項對建立文字檔很有用。This example also uses the AcceptsTab, AcceptsReturn, and WordWrap properties to make the multiline TextBox control useful for creating text documents.

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

如果屬性設定為,就不會顯示水準捲軸 WordWrap true ,不論屬性的值為何 ScrollBarsHorizontal scroll bars will not be shown if the WordWrap property is set to true, regardless of the value of the ScrollBars property.
