Examples

The following code example handles the MouseDown event on a TextBox control so that clicking the right mouse button selects all the text in the control. This example requires that you have a form that contains a TextBox control named textBox1.

private void Form1_Load(object sender, EventArgs e)
{
    // This line suppresses the default context menu for the TextBox control. 
    textBox1.ContextMenu = new ContextMenu();
    textBox1.MouseDown += new MouseEventHandler(textBox1_MouseDown);
}

void textBox1_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e)
{
    if (e.Button == MouseButtons.Right)
    {
        textBox1.Select(0, textBox1.Text.Length);
    }
}
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
    TextBox1.ContextMenu = New ContextMenu()
End Sub

Private Sub TextBox1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles TextBox1.MouseDown
    If (e.Button = Windows.Forms.MouseButtons.Right) Then
        TextBox1.Select(0, TextBox1.Text.Length)
    End If
End Sub
