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.ScrollBarArrowBu ttonState.UpNormal);
}
else if (_UpButtonStatus == 1)
{
ScrollBarRenderer.DrawArrowButton(e.Graphics,
this._UpButton.ClientRectangle,
System.Windows.Forms.VisualStyles.ScrollBarArrowBu ttonState.UpPressed);
}
else
{
ScrollBarRenderer.DrawArrowButton(e.Graphics,
this._UpButton.ClientRectangle,
System.Windows.Forms.VisualStyles.ScrollBarArrowBu ttonState.UpHot);
}
}
void DownButton_Paint(object sender, PaintEventArgs e)
{
if (_DownButtonStatus == 0)
{
ScrollBarRenderer.DrawArrowButton(e.Graphics,
this._UpButton.ClientRectangle,
System.Windows.Forms.VisualStyles.ScrollBarArrowBu ttonState.DownNormal);
}
else if (_DownButtonStatus == 1)
{
ScrollBarRenderer.DrawArrowButton(e.Graphics,
this._UpButton.ClientRectangle,
System.Windows.Forms.VisualStyles.ScrollBarArrowBu ttonState.DownPressed);
}
else
{
ScrollBarRenderer.DrawArrowButton(e.Graphics,
this._UpButton.ClientRectangle,
System.Windows.Forms.VisualStyles.ScrollBarArrowBu ttonState.DownHot);
}
}
}
