I am using drag and drop event to add nodes from SymbolPalette.
I would also like to support mouse double click or other hot keys for adding nodes on the diagram.

I have added event to handle double click event and in this event the node is added to the diagram. Following is the code snippet for the same.
        private void listView_PreviewMouseDoubleClick(object sender, MouseButtonEventArgs e)
            var selectedPalette = ((System.Windows.Controls.Primitives.Selector)(sender)).SelectedItem as SymbolPaletteItem;
            if (selectedPalette != null)
                var node1 = selectedPalette.Content as Node;
                if (node1 != null)
                    var node = Nodes.Nodes.GetNode(node1.Name);

Now my node is added to collection of nodes in the diagram control model. But I cannot see the ports associated with this node, nor I can select it using single click.

Am I missing on any of the steps while adding the node to diagram control.
