TextBoxBase.HideSelection 属性

定义

命名空间:

System.Windows.Forms

程序集:

System.Windows.Forms.dll

获取或设置一个值，该值指示当文本框控件没有焦点时，该控件中选定的文本是否保持突出显示。

public:
 property bool HideSelection { bool get(); void set(bool value); };

public bool HideSelection { get; set; }

member this.HideSelection : bool with get, set

Public Property HideSelection As Boolean

属性值

Boolean

如果当文本框控件没有焦点时，选定文本不突出显示，则为 true；如果当文本框控件没有焦点时，选定文本保持突出显示，则为 false。 默认值为 true。

示例

下面的代码示例演示如何使用 HideSelection 属性。 若要运行该示例，请将以下代码粘贴到窗体中。 InitializeTextBox在窗体的构造函数或 Load 方法中调用 方法。

   //Declare a textbox called TextBox1.
internal:
   System::Windows::Forms::TextBox^ TextBox1;

private:

   //Initialize TextBox1.
   void InitializeTextBox()
   {
      this->TextBox1 = gcnew TextBox;
      this->TextBox1->Location = System::Drawing::Point( 32, 24 );
      this->TextBox1->Name = "TextBox1";
      this->TextBox1->Size = System::Drawing::Size( 136, 20 );
      this->TextBox1->TabIndex = 1;
      this->TextBox1->Text = "Type and hit enter here...";
      
      //Keep the selection highlighted, even after textbox loses focus.
      TextBox1->HideSelection = false;
      this->Controls->Add( TextBox1 );
   }

//Declare a textbox called TextBox1.
internal System.Windows.Forms.TextBox TextBox1;

//Initialize TextBox1.
private void InitializeTextBox()
{
    this.TextBox1 = new TextBox();
    this.TextBox1.Location = new System.Drawing.Point(32, 24);
    this.TextBox1.Name = "TextBox1";
    this.TextBox1.Size = new System.Drawing.Size(136, 20);
    this.TextBox1.TabIndex = 1;
    this.TextBox1.Text = "Type and hit enter here...";

    //Keep the selection highlighted, even after textbox loses focus.
    TextBox1.HideSelection = false;
    this.Controls.Add(TextBox1);
}

'Declare a textbox called TextBox1.
Friend WithEvents TextBox1 As System.Windows.Forms.TextBox

'Initialize TextBox1.
Private Sub InitializeTextBox()
    Me.TextBox1 = New TextBox
    Me.TextBox1.Location = New System.Drawing.Point(32, 24)
    Me.TextBox1.Name = "TextBox1"
    Me.TextBox1.Size = New System.Drawing.Size(136, 20)
    Me.TextBox1.TabIndex = 1
    Me.TextBox1.Text = "Type and hit enter here..."

    'Keep the selection highlighted, even after textbox loses focus.
    TextBox1.HideSelection = False
    Me.Controls.Add(TextBox1)
End Sub

注解

当其他窗体或对话框具有焦点（例如拼写检查器对话框）时，可以使用此属性在文本框控件中突出显示文本。
