ColorDialog Class

Represents a common dialog box that displays available colors along with controls that enable the user to define custom colors.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public class ColorDialog : CommonDialog

The inherited member ShowDialog must be invoked to create this specific common dialog box. HookProc can be overridden to implement specific dialog box hook functionality. Use Color to retrieve the color selected by the user.

When you create an instance of ColorDialog, some of the read/write properties are set to initial values. For a list of these values, see the ColorDialog constructor.

The following example illustrates the creation of new ColorDialog. This example requires that the method is called from within an existing form that has a TextBox and Button placed on it.

private void button1_Click(object sender, System.EventArgs e)
 {
    ColorDialog MyDialog = new ColorDialog();
    // Keeps the user from selecting a custom color.
    MyDialog.AllowFullOpen = false ;
    // Allows the user to get help. (The default is false.)
    MyDialog.ShowHelp = true ;
    // Sets the initial color select to the current text color.
    MyDialog.Color = textBox1.ForeColor ;

    // Update the text box color if the user clicks OK  
    if (MyDialog.ShowDialog() == DialogResult.OK)
        textBox1.ForeColor =  MyDialog.Color;
 }
