Node Effects on Custom Nodes

Hi there,

I saw this example http://www.mindfusion.eu/onlinehelp/wpfdiagram/index.htm on your website and wanted to try it out. But i think it's not working because we're using custom nodes. Could you give any tips?

Thanks in advance.

Greets,

Sander

Hi,

The built-in effects cannot be applied to custom nodes, because the control cannot know to which parts of your custom-drawn WPF visual tree they should be applied. These effects mostly add some radial gradients to the nodes' background, so you should be able to draw something similar in the Draw override using a RadialGradientBrush at the locations you want 'reflections' to appear.

I hope that helps,
Stoyan

Ok thanks! I was using that at the moment, but i didn't know it could look that fancy using the RadialGradientBrush.

You could set the node's UIElement.Effect property to a DropShadowEffect instance. That's not one of ours but provided by WPF.

I hope that helps,

Ah, that looks nice. Are there any other nice effects that could make the nodes look a bit more fancy?

Thanks in advance.

Check the other effect classes in the Inheritance Hierarchy section here, I'm not sure what they do:
http://msdn.microsoft.com/en-us/library/system.windows.media.effects.effect.aspx

You could also change the UIElement.Opacity property to make your nodes translucent.

I hope that helps,

Thanks, this has some nice features, but i'm surprised that its quite concise. In other words, the visual options that wpf offers isn't that extensive.
