TextBoxBase.HideSelection 属性
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。
**命名空间:**System.Windows.Forms
**程序集:**System.Windows.Forms（在 system.windows.forms.dll 中）
语法
声明
Public Property HideSelection As Boolean
用法
Dim instance As TextBoxBase
Dim value As Boolean
value = instance.HideSelection
instance.HideSelection = value
public bool HideSelection { get; set; }
public:
property bool HideSelection {
bool get ();
void set (bool value);
}
/** @property */
public boolean get_HideSelection ()
/** @property */
public void set_HideSelection (boolean value)
public function get HideSelection () : boolean
public function set HideSelection (value : boolean)
属性值
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。默认为 true。
备注
当另一个窗体或对话框（如拼写检查对话框）有焦点时，可以使用此属性使文本框控件中的文本保持突出显示。
示例
下面的代码示例演示如何使用 HideSelection 属性。要运行该示例，请将以下代码粘贴到一个窗体中。在窗体的构造函数或 Load 方法中调用 InitializeTextBox 方法。
'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
//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.
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.
System.Windows.Forms.TextBox textBox1;
//Initialize TextBox1.
private void InitializeTextBox()
{
this.textBox1 = new TextBox();
this.textBox1.set_Location(new System.Drawing.Point(32, 24));
this.textBox1.set_Name("TextBox1");
this.textBox1.set_Size(new System.Drawing.Size(136, 20));
this.textBox1.set_TabIndex(1);
this.textBox1.set_Text("Type and hit enter here...");
//Keep the selection highlighted, even after textbox loses focus.
textBox1.set_HideSelection(false);
this.get_Controls().Add(textBox1);
} //InitializeTextBox
