Button derived color selection control similar to the one used in MS Office applications.

Sample Image - ColorButton.gif


ColorButton is a color selection control derived from System.Windows.Forms.Button similar to the one used in MS Office applications. It uses the same colors like MS Office, including support for "Automatic" and "More Colors".

How To Use

Add a normal Button to your Windows Form and set the Text property to an empty string. Then manually change all occurrences of System.Windows.Forms.Button to ColorButton.ColorButton for this button in the source file.


ColorButton adds the following new properties:

Color (get/set)

Gets or sets the selected color. System.Drawing.Color.Transparent is used for the "Automatic" color.

Automatic (get/set)

Gets or sets the string for the "Automatic" button. Setting this to an empty string disables the "Automatic" color feature.

MoreColors (get/set)

Gets or sets the string for the "More Colors" button. Setting this to an empty string disables the "More Colors" color feature.


ColorButton adds the following new event:


This event occurs whenever the user changes the selected color. Use the Color property to determine what the selected color is.

GeneralFixed Control for Clipregion PinmemberCodeMonkey3315-Sep-06 7:23 
Great control! I found a small bug that shows up when another window is dragged over the top of the color control. The button does not draw properly because it is using the clip region as the entire size of the button. I switched the OnPaint call to use 'ClientRectangle' instead and that fixed it for me.
protected override void OnPaint( PaintEventArgs e )
base.OnPaint( e ) ;
int offset = 0 ;
if( panelVisible || ( buttonPushed &&
RectangleToScreen( ClientRectangle ).Contains( Cursor.Position ) ) )
ControlPaint.DrawButton( e.Graphics, e.ClipRectangle, ButtonState.Pushed ) ;
offset = 1 ;
Rectangle rc = new Rectangle( ClientRectangle.Left + 5 + offset,
ClientRectangle.Top + 5 + offset,
ClientRectangle.Width - 24,
ClientRectangle.Height - 11 ) ;

Pen textPen = new Pen( Enabled ? SystemColors.ControlText : SystemColors.GrayText ) ;
Point pt = new Point( rc.Right, ( ClientRectangle.Height + offset ) / 2 ) ;
e.Graphics.DrawLine( textPen, pt.X + 9, pt.Y - 1, pt.X + 13, pt.Y - 1 ) ;
e.Graphics.DrawLine( textPen, pt.X + 10, pt.Y, pt.X + 12, pt.Y ) ;
e.Graphics.DrawLine( textPen, pt.X + 11, pt.Y, pt.X + 11, pt.Y + 1 ) ;
