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)
{
base.Initialize();
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;
}
}
Public Class CustomActivityDesignerTheme
Inherits ActivityDesignerTheme
Public Sub New(ByVal theme As WorkflowTheme)
MyBase.new(theme)
MyBase.Initialize()
Me.BorderStyle = DashStyle.Solid
Me.BorderColor = Color.FromArgb(0, 0, 0)
Me.BackColorStart = Color.FromArgb(37, 15, 242)
Me.BackColorEnd = Color.FromArgb(189, 184, 254)
Me.BackgroundStyle = LinearGradientMode.Vertical
Me.ForeColor = Color.Black
End Sub
End Class
To use the theme on an ActivityDesigner, apply the ActivityDesignerThemeAttribute to the ActivityDesigner class.
