Designer themes define the look and feel of a designer. This includes any background styles, foreground styles, fonts, and icons defined for the designer.

You can create a custom designer theme if you want to provide configuration abilities to properties unique to your designer. If you do not specify a designer theme for a custom designer, the theme from the base class is used.

The following example shows how to create a custom ActivityDesignerTheme by deriving from the ActivityDesignerTheme class and setting the appropriate properties for the new theme.

public class CustomActivityDesignerTheme : ActivityDesignerTheme
    public CustomActivityDesignerTheme(WorkflowTheme theme)
        : base(theme)
        this.BorderStyle = DashStyle.Solid;
        this.BorderColor = Color.FromArgb(0, 0, 0);
        this.BackColorStart = Color.FromArgb(37, 15, 242);
        this.BackColorEnd = Color.FromArgb(189, 184, 254);
        this.BackgroundStyle = LinearGradientMode.Vertical;
        this.ForeColor = Color.Black;

To use the theme on an ActivityDesigner, apply the ActivityDesignerThemeAttribute to the ActivityDesigner class.
