Looking for C# Spin Control

Is there a control equivalent to the old Spin control? The one with two hour heads and an optional
textbox in the middle? The closest I can find is the NumericUpDown control and it's not the same as
the Spin control. I just want a sizeable up/down arrow pair.

Hello Stewart,

Thank you for using Microsoft Managed Newsgroup Service, my name is Zhi-Xin
Ye, it's my pleasure to work with you on this issue.

You can create an UserControl, put two buttons in it, one on the top and
the other on the bottom. Handle the Paint event of the buttons and use
ScrollBarRenderer.DrawArrowButton() method to draw arrows on the buttons.

For example:

========= Sample code for your information ==============

public class SpinControl : UserControl
{
private Button _UpButton;
private Button _DownButton;

//Button status 0:Normal, 1:Pressed; 2:Hot(Mouse Hover)
private int _UpButtonStatus = 0;
private int _DownButtonStatus = 0;

public SpinControl()
{
this._UpButton = new Button();
this._DownButton = new Button();
this._UpButton.Paint += new PaintEventHandler(UpButton_Paint);
this._DownButton.Paint += new PaintEventHandler(DownButton_Paint);

this._UpButton.MouseDown += new
MouseEventHandler(_UpButton_MouseDown);
this._UpButton.MouseUp += new MouseEventHandler(_UpButton_MouseUp);

this._DownButton.MouseDown += new
MouseEventHandler(_DownButton_MouseDown);
this._DownButton.MouseUp += new
MouseEventHandler(_DownButton_MouseUp);

this._UpButton.MouseEnter += new EventHandler(_UpButton_MouseEnter);
this._DownButton.MouseEnter += new
EventHandler(_DownButton_MouseEnter);

this._UpButton.MouseLeave += new EventHandler(_UpButton_MouseLeave);
this._DownButton.MouseLeave += new
EventHandler(_DownButton_MouseLeave);

this.AjustArrowButtonSize();
this.Controls.Add(this._UpButton);
this.Controls.Add(this._DownButton);
this.Width = 20;
}

void _UpButton_MouseLeave(object sender, EventArgs e)
{
_UpButtonStatus = 0;
}

void _UpButton_MouseUp(object sender, MouseEventArgs e)
{
_UpButtonStatus = 0;
}

void _UpButton_MouseDown(object sender, MouseEventArgs e)
{
_UpButtonStatus = 1;
}

void _UpButton_MouseEnter(object sender, EventArgs e)
{
_UpButtonStatus = 2;
}

void _DownButton_MouseUp(object sender, MouseEventArgs e)
{
_DownButtonStatus = 0;
}
void _DownButton_MouseLeave(object sender, EventArgs e)
{
_DownButtonStatus = 0;

}
void _DownButton_MouseDown(object sender, MouseEventArgs e)
{
_DownButtonStatus = 1;
}
void _DownButton_MouseEnter(object sender, EventArgs e)
{
_DownButtonStatus = 2;
}

protected override void OnResize(EventArgs e)
{
this.AjustArrowButtonSize();
base.OnResize(e);
}

private void AjustArrowButtonSize()
{
this._UpButton.Size = this.Size;
this._DownButton.Size = this.Size;
this._UpButton.Height /= 2;
this._DownButton.Height /= 2;
this._DownButton.Top = this._UpButton.Bottom;
}

void UpButton_Paint(object sender, PaintEventArgs e)
{
if (_UpButtonStatus == 0 )
{
ScrollBarRenderer.DrawArrowButton(e.Graphics,
this._UpButton.ClientRectangle,

System.Windows.Forms.VisualStyles.ScrollBarArrowButtonState.UpNormal);
}
else if (_UpButtonStatus == 1)
{
ScrollBarRenderer.DrawArrowButton(e.Graphics,
this._UpButton.ClientRectangle,

System.Windows.Forms.VisualStyles.ScrollBarArrowButtonState.UpPressed);
}
else
{
ScrollBarRenderer.DrawArrowButton(e.Graphics,
this._UpButton.ClientRectangle,

System.Windows.Forms.VisualStyles.ScrollBarArrowButtonState.UpHot);
}

}

void DownButton_Paint(object sender, PaintEventArgs e)
{
if (_DownButtonStatus == 0)
{
ScrollBarRenderer.DrawArrowButton(e.Graphics,
this._UpButton.ClientRectangle,

System.Windows.Forms.VisualStyles.ScrollBarArrowButtonState.DownNormal);
}
else if (_DownButtonStatus == 1)
{
ScrollBarRenderer.DrawArrowButton(e.Graphics,
this._UpButton.ClientRectangle,

System.Windows.Forms.VisualStyles.ScrollBarArrowButtonState.DownPressed);
}
else
{
ScrollBarRenderer.DrawArrowButton(e.Graphics,
this._UpButton.ClientRectangle,

System.Windows.Forms.VisualStyles.ScrollBarArrowButtonState.DownHot);
}
}
}

Why create a new de facto enum type without even naming the constants? You
already have the System.Windows.Forms.VisualStyles.ScrollBarArrowButtonState
enum which has exactly what you want, and you can avoid the if statements
later on.
 
Hi Ben,

You're right, it's more concise to use the ScrollBarArrowButtonState enum,
I somehow ignore that.

public class SpinControl : UserControl
{
private Button _UpButton;
private Button _DownButton;

private ScrollBarArrowButtonState _UpButtonStatus;
private ScrollBarArrowButtonState _DownButtonStatus;

public SpinControl()
{
this._UpButton = new Button();
this._DownButton = new Button();
this._UpButton.Paint += new PaintEventHandler(UpButton_Paint);
this._DownButton.Paint += new PaintEventHandler(DownButton_Paint);

this._UpButton.MouseDown += new
MouseEventHandler(_UpButton_MouseDown);
this._UpButton.MouseUp += new MouseEventHandler(_UpButton_MouseUp);

this._DownButton.MouseDown += new
MouseEventHandler(_DownButton_MouseDown);
this._DownButton.MouseUp += new
MouseEventHandler(_DownButton_MouseUp);

this._UpButton.MouseEnter += new EventHandler(_UpButton_MouseEnter);
this._DownButton.MouseEnter += new
EventHandler(_DownButton_MouseEnter);

this._UpButton.MouseLeave += new EventHandler(_UpButton_MouseLeave);
this._DownButton.MouseLeave += new
EventHandler(_DownButton_MouseLeave);

this.AjustArrowButtonSize();
this.Controls.Add(this._UpButton);
this.Controls.Add(this._DownButton);
this.Width = 20;
}

void _UpButton_MouseLeave(object sender, EventArgs e)
{
_UpButtonStatus = ScrollBarArrowButtonState.UpNormal;
}

void _UpButton_MouseUp(object sender, MouseEventArgs e)
{
_UpButtonStatus = ScrollBarArrowButtonState.UpNormal;
}

void _UpButton_MouseDown(object sender, MouseEventArgs e)
{
_UpButtonStatus = ScrollBarArrowButtonState.UpPressed;
}

void _UpButton_MouseEnter(object sender, EventArgs e)
{
_UpButtonStatus = ScrollBarArrowButtonState.UpHot;
}

void _DownButton_MouseUp(object sender, MouseEventArgs e)
{
_DownButtonStatus = ScrollBarArrowButtonState.DownNormal;
}
void _DownButton_MouseLeave(object sender, EventArgs e)
{
_DownButtonStatus = ScrollBarArrowButtonState.DownNormal;

}
void _DownButton_MouseDown(object sender, MouseEventArgs e)
{
_DownButtonStatus = ScrollBarArrowButtonState.DownPressed;
}
void _DownButton_MouseEnter(object sender, EventArgs e)
{
_DownButtonStatus = ScrollBarArrowButtonState.DownHot;
}

protected override void OnResize(EventArgs e)
{
this.AjustArrowButtonSize();
base.OnResize(e);
}

private void AjustArrowButtonSize()
{
this._UpButton.Size = this.Size;
this._DownButton.Size = this.Size;
this._UpButton.Height /= 2;
this._DownButton.Height /= 2;
this._DownButton.Top = this._UpButton.Bottom;
}

void UpButton_Paint(object sender, PaintEventArgs e)
{
ScrollBarRenderer.DrawArrowButton(e.Graphics,
this._UpButton.ClientRectangle, _UpButtonStatus);
}

void DownButton_Paint(object sender, PaintEventArgs e)
{
ScrollBarRenderer.DrawArrowButton(e.Graphics,
this._UpButton.ClientRectangle, _DownButtonStatus);
}
}

It makes sense. However, I already rolled my own ArrowButton and SpinButton controls.

The ArrowButton restricts the "clickable" area to the area inside the arrow -- not the rectangle it
is panted in. It also has a "Faces" property so I can use it as up, down, left or right.

The SpinButton uses two ArrowButton controls and a Label.
