TextBox.ScrollBars 属性

获取或设置哪些滚动条应出现在多行 TextBox 控件中。

**命名空间:**System.Windows.Forms
**程序集:**System.Windows.Forms（在 system.windows.forms.dll 中）

语法

声明
<LocalizableAttribute(True)> _
Public Property ScrollBars As ScrollBars
用法
Dim instance As TextBox
Dim value As ScrollBars

value = instance.ScrollBars

instance.ScrollBars = value

[LocalizableAttribute(true)] 
public ScrollBars ScrollBars { get; set; }

[LocalizableAttribute(true)] 
public:
property ScrollBars ScrollBars {
    ScrollBars get ();
    void set (ScrollBars value);
}

/** @property */
public ScrollBars get_ScrollBars ()

/** @property */
public void set_ScrollBars (ScrollBars value)

public function get ScrollBars () : ScrollBars

public function set ScrollBars (value : ScrollBars)

属性值

ScrollBars 枚举值之一，它指示多行 TextBox 控件显示时是不带滚动条、带有水平滚动条、带有垂直滚动条还是同时带有这两种滚动条。默认为 ScrollBars.None。

异常

异常类型	条件
InvalidEnumArgumentException	分配给该属性的值不在该枚举的有效值范围内。

备注

如果将 WordWrap 属性设置为 true，则不管 ScrollBars 属性的值是什么，都不会显示水平滚动条。

示例

下面的代码示例创建带垂直滚动条的多行 TextBox 控件。此示例还使用 AcceptsTab、AcceptsReturn 和 WordWrap 属性来使多行 TextBox 控件可用于创建文本文档。

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

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:
   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.set_Multiline(true);
    // Add vertical scroll bars to the TextBox control.
    textBox1.set_ScrollBars(ScrollBars.Vertical);
    // Allow the TAB key to be entered in the TextBox control.
    textBox1.set_AcceptsReturn(true);
    // Allow the TAB key to be entered in the TextBox control.
    textBox1.set_AcceptsTab(true);
    // Set WordWrap to true to allow text to wrap to the next line.
    textBox1.set_WordWrap(true);
    // Set the default text of the control.
    textBox1.set_Text("Welcome!");
} //CreateMyMultilineTextBox
