I changed some code. Hope this one works
public class MyButton : System.Windows.Forms.Panel
{
public MyButton()
: base()
{
this.MouseDown += new System.Windows.Forms.MouseEventHandler(MyButton_MouseDown);
this.MouseUp += new System.Windows.Forms.MouseEventHandler(MyButton_MouseUp);
this.MouseMove += new System.Windows.Forms.MouseEventHandler(MyButton_MouseMove);
this.Resize += new EventHandler(MyButton_Resize);
this.Cursor = Cursors.SizeNWSE;
this.Controls.Add(_Button);
_Button.Cursor = Cursors.Hand;
this.BackColor = Color.Red;
}
void MyButton_Resize(object sender, EventArgs e)
{
_Button.Location = new Point(2, 2);
_Button.Size = new Size(this.Width - 4, this.Height - 4);
}
private Button _Button = new Button();
private int x;
private int y;
public Button Button
{
get { return _Button; }
set { _Button = value; }
}
private bool allowResize = false;
private int mousex;
private int mousey;
void MyButton_MouseMove(object sender, System.Windows.Forms.MouseEventArgs e)
{
if (allowResize)
{
if (this.Width / 2 > e.X)
{
if (this.Height / 2 < e.Y)
{
this.Left = this.Left + (e.X - mousex);
this.Height = e.Y;
this.Width = this.Width - (e.X - mousex);
}
else
{
this.Left = this.Left + (e.X - mousex);
this.Top = this.Top + (e.Y - mousey);
this.Width = this.Width - (e.X - mousex);
this.Height = this.Height - (e.Y - mousey);
}
}
else
{
if (this.Height / 2 < e.Y)
{
this.Width = e.X;
this.Height = e.Y;
}
else
{
this.Top = this.Top + (e.Y - mousey);
this.Width = e.X;
this.Height = this.Height - (e.Y - mousey);
}
}
}
}
void MyButton_MouseUp(object sender, System.Windows.Forms.MouseEventArgs e)
{
allowResize = false;
}
void MyButton_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e)
{
allowResize = true;
mousex = e.X;
mousey = e.Y;
}
}

Do you want end user to resize it from gui or you want to resize it by code? |

You should write your own control. Here is a sample I made 2-3 years ago. The main idea is putting button into a panel that 2 pixel larger than button and listening panels mousedown mouseup and mousemove events. And resizing button with panel. Hope it helps.
public class MyButton : System.Windows.Forms.Panel
{
public MyButton()
: base()
{
this.MouseDown += new System.Windows.Forms.MouseEventHandler(MyButton_MouseDown);
this.MouseUp += new System.Windows.Forms.MouseEventHandler(MyButton_MouseUp);
this.MouseMove += new System.Windows.Forms.MouseEventHandler(MyButton_MouseMove);
this.Resize += new EventHandler(MyButton_Resize);
this.Cursor = Cursors.SizeNWSE;
this.Controls.Add(_Button);
_Button.Cursor = Cursors.Hand;
this.BackColor = Color.Red;
}
void MyButton_Resize(object sender, EventArgs e)
{
_Button.Location = new Point(2, 2);
_Button.Size = new Size(this.Width - 4, this.Height - 4);
}
private Button _Button = new Button();
public Button Button
{
get { return _Button; }
set { _Button = value; }
}
private bool allowResize = false;
void MyButton_MouseMove(object sender, System.Windows.Forms.MouseEventArgs e)
{
if (allowResize)
{
this.Width = e.X;
this.Height = e.Y;
}
}
void MyButton_MouseUp(object sender, System.Windows.Forms.MouseEventArgs e)
{
allowResize = false;
}
void MyButton_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e)
{
allowResize = true;
}
}

Hi, If you are interested, I created a custom control that allows your user to move, size and align form controls at run-time. The custom control DLL is free for commercial and non-commercial use and canbe found at : http://www.sharpcontrols.net/Controls/SharpControlSelect.aspxAny comments on the control would be gratefully accepted.
