Change default alpha for new nodes

[Kelly Harrison]

New here, so bear with me....

Is it possible to set the default alpha value for all new nodes added to a diagram?

Do I need to create a custom symbol?

Thanks!

I guess I should point out that I'm working with rectangles exclusively. I'm messing around with the DrawShapes_2008 sample.

Hi ,

Thanks for your interest in Syncfusion products.

To change the default alpha factor of the nodes, you have to handle NodeCollectionChanging event of DocumentEventSink and use FillStyle.ColorAlphaFactor of the node in this event. Please refer to the below code snippet.

this.diagram1.Model.EventSink.NodeCollectionChanging += new CollectionExEventHandler(EventSink_NodeCollectionChanging);
void EventSink_NodeCollectionChanging(CollectionExEventArgs evtArgs)
{
if (evtArgs.Element is Rectangle)
{
Rectangle m_rect = evtArgs.Element as Rectangle;
m_rect.FillStyle.ColorAlphaFactor = 80;
}
}

Here is the working sample.

Please let me know if this helps.
