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:
public MyUIPanelManager()
: base()
{
this.TabbedMdiSettings.TabStripFormatStyle.BackColor = ApplicationTheme.ThemeProperties.ThemeFormBorderGradientBegin;
this.TabbedMdiSettings.TabStripFormatStyle.BackColorGradient = ApplicationTheme.ThemeProperties.ThemeFormBorderGradientEnd;
}
But I get a runtime error:
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.
