Apply theme properties to custom control

Alex Bibiano González — Wed, 02 Dec 2009 09:31:17 GMT

I have a custom control inherited from another control.

I want to apply to this custom some SF ThemeProperties to integrate it with the SF themed controls.

What’s the best approach to do it?

I have tried to do it on to constructor with this code:

[code]public MyUIPanelManager()
            : base()
        {
            this.TabbedMdiSettings.TabStripFormatStyle.BackColor = ApplicationTheme.ThemeProperties.ThemeFormBorderGradientBegin;
            this.TabbedMdiSettings.TabStripFormatStyle.BackColorGradient = ApplicationTheme.ThemeProperties.ThemeFormBorderGradientEnd;
        }[/code]

But I get a runtime error:

[code]ApplicationException
An error occurred while creating the main form
TargetInvocationException
Se produjo una excepción en el destino de la invocación.
NullReferenceException
Referencia a objeto no establecida como instancia de un objeto.
