I need to add custom propery in nshape

and

how to create custom shape with image


Thanks

Hi Wilhelm,

Yes sure - the default diagram property grid uses the PropertyGrid of the .NET framework. If you define a Tag object to each shape then you need to simply subscribe for the NodeSelected and NodeDeselected events of the view event sink service. For a form on which you have dropped a PropertyGrid control use this code (also demonstrates how to make a custom tag):

private void Form1_Load(object sender, EventArgs e)
{
...
// assing a tag to a shape (actually you can assign a tag to all diagram elements)
shape.Tag = new MyTag();

// subscribe for the node selected/deselected events
nDrawingView1.EventSinkService.NodeSelected += new Nevron.Dom.NodeEventHandler(EventSinkService_NodeSelected);

nDrawingView1.EventSinkService.NodeDeselected += new Nevron.Dom.NodeEventHandler(EventSinkService_NodeDeselected);
}

void EventSinkService_NodeDeselected(Nevron.Dom.NNodeEventArgs args)
{
propertyGrid1.SelectedObject = null;
}

void EventSinkService_NodeSelected(Nevron.Dom.NNodeEventArgs args)
{
NDiagramElement element = args.Node as NDiagramElement;
if (element == null)
return;

propertyGrid1.SelectedObject = element.Tag;
}
