Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in system.windows.forms.dll)

public bool HideSelection { get; set; }

/** @property */
public void set_HideSelection (boolean value)

Property Value

true if the selected text does not appear highlighted when the text box control loses focus; false, if the selected text remains highlighted when the text box control loses focus. The default is true.

You can use this property to keep text highlighted in a text box control while another form or a dialog box has focus, such as a spelling checker dialog box.

The following code example demonstrates how to use the HideSelection property. To run the example, paste the following code in a form. Call the InitializeTextBox method in the form's constructor or Load method.

//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.
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
