node has background color but also transparent

Question

I am setting the background color of a node.

node.OffsetX = offsetx;
node.OffsetY = offsety;
node.Width = width;
node.Height = MinLaneHeight;
node.Background = this.Resources[background] as SolidColorBrush;

How would I also make it transparent to show the horizontal/vertical lines?

I meant to say I want to display the horizontal/vertical grid lines for the nodes.   So the node has a background color but also shows the grid lines.

I'm also interested in how to do this, for the Node() object there doesn't appear to be a FillColour attribute, and setting Background-Color to null seems to make it black (i guess null => #000)

I'm just evaluating the sample FlatDiagram, and trying to get that Decision diamond to be transparent (so the arrows are not hidden)

Any ideas?

thanks!
Dave

Hi Mary,Node’s shape can be customized by using its CustomPathStyle property. The background of the Node’s Shape can be made transparent by applying the Transparent Brush to  Fill Property of the Node’s CustomPathStyle. We have created the sample based on your requirement. Please refer to the sample from the attachment.Please let us know if you have any further queries and we will be happy to help you out.Regards,RamyaNodeBackground_1a5a1bd7.zip

Thanks, that helped me figure out what I was doing wrong.

I did have an opacity setting on the node background color.

I dont remember when I added this line:

diagramView.Page.Background = new SolidColorBrush(Colors.White);

but it caused the horizontal/vertical grid lines to go away.
I understand why now.
