Modifying renderer properties

Hi Gareth,

Absolutely... we made our renderers so you can design your own from scratch or simply change the properties of ours. NavigationBarHeaderBackgroundFill is a BackgroundFill type so you can create any sort of BackgroundFill to set to that property. Some examples are SolidColorBackgroundFill, TwoColorBackgroundFill, ImageBackgroundFill, etc. All of them are in the ActiproSoftware.Drawing namespace.

When you run the NavigationBar sample, you can click the Renderer tag, select a BackgroundFill property, and click the ... button to see a designer window that shows the BackgroundFill in detail with a preview and allows you to select other types of BackgroundFills.

Thanks for that. I forgot to mention that I am trying to do this from code at runtime. I can see how to do it via the designer, but the relevant properties don't seem to be accessible through code.... I must be missing something!

Thanks,
Gareth.

The core renderer properties are simple interfaces, like INavigationBarRenderer. Each implementation exposes its own properties. So you need to cast the renderer (from RendererResolved property) to its appropriate renderer type. Then you can access the BackgroundFill properties.

So once you have that property reference, you can create a background fill like this: Set that to the property and you're all done.

Excellent! Thank-you. I didn't realise what RendererResolved was for. For anyone interested, an example of the full code is: Cheers,
Gareth.

By the way, RendererResolved returns the global renderer if no control-specific renderer
is set in the Renderer property. There is a documentation that covers renderers
so check that out for more info.
