Metin kutusu denetiminin davranışlarını özel denetimime nasıl ekleyebilirim?

Question

Özel yuvarlak metin kutum var. Ancak metin düzenleme, metin seçimi vb. Gibi metin kutusu davranışlarını ekleyemedim. Kendimi yapmaya karar verirsem bu özellikler çok zaman alır. Bu özellikleri metin kutusuna nasıl ekleyebilirim?

Benim TextBox sınıfı: Ben Hazeldev's custom controls bir çözüm bulduk

Bu çözümde çocuk kontrolümüz olarak bir metin kutusu kontrolü ekliyoruz.

public class AltoTextBox : Control 
{ 
    int radius = 15; 
    public TextBox box = new TextBox(); 
    GraphicsPath Shape; 
    public AltoTextBox() 
    { 
     SetStyle(ControlStyles.SupportsTransparentBackColor, true); 
     SetStyle(ControlStyles.UserPaint, true); 
     SetStyle(ControlStyles.ResizeRedraw, true); 

     AddTextBox(); 
     Controls.Add(box); 

     BackColor = Color.Transparent; 
     ForeColor = Color.DimGray; 

     Text = null; 
     Font = new Font("Comic Sans MS", 11); 
     Size = new Size(135, 33); 
     DoubleBuffered = true; 
    } 
    void AddTextBox() 
    { 
     box.Size = new Size(Width - 2*radius, Height - 6); 
     box.Location = new Point(radius, 3); 
     box.BorderStyle = BorderStyle.None; 
     box.TextAlign = HorizontalAlignment.Left; 
     box.Multiline = true; 
     box.Font = Font; 
    } 
    protected override void OnBackColorChanged(EventArgs e) 
    { 
     base.OnBackColorChanged(e); 
    } 
    protected override void OnTextChanged(EventArgs e) 
    { 
     base.OnTextChanged(e); 
     box.Text = Text; 
    } 
    GraphicsPath innerRect; 
    protected override void OnFontChanged(EventArgs e) 
    { 
     base.OnFontChanged(e); 
     box.Font = Font; 
    } 
    protected override void OnResize(System.EventArgs e) 
    { 
     base.OnResize(e); 
     Shape = new RoundedRectangleF(Width, Height, radius).Path; 
     innerRect = new RoundedRectangleF(Width - 0.5f, Height - 0.5f, radius, 0.5f, 0.5f).Path; 

     AddTextBox(); 
    } 
    protected override void OnPaint(PaintEventArgs e) 
    { 
     Bitmap bmp = new Bitmap(Width, Height); 
     Graphics grp = Graphics.FromImage(bmp); 
     grp.SmoothingMode = SmoothingMode.HighQuality; 
     grp.DrawPath(Pens.Gray, Shape); 
     grp.FillPath(Brushes.White, innerRect); 
     e.Graphics.DrawImage((Image)bmp.Clone(), 0, 0); 

     base.OnPaint(e); 
    } 

}
