	Hi Stoyo, Is it possible to view and set properties for custom node types (some string and numeric values) in the property grid, during runtime. I am trying to set the selected node as the object for property grid but it doesn't work.

	Hi, Are your custom properties public? I think the property grid displays only public properties. Stoyan

	Hi Stoyo, Find the code snippets attached. The properties are public. Code public class cNode : ShapeNode { public string label; public string Label { get { return label; } set { label = value;} } } Code private void diagram1_NodeSelected(object sender, NodeEventArgs e) { DiagramNode node = e.Node; cNode cnode = node as cNode; propertyGrid1.SelectedObject = cnode; }

	Also, when I create a new cNode object in my form constructor, the property grid shows the custom properties. However, it doesn't show for the specific nodes that are created within diagramView.

	Do you mean nodes drawn with the mouse don't have these properties? That probably happens because the nodes are ShapeNode instances. You will have to set Behavior = Custom and CustomNodeType = typeof(cNode) to enable drawing custom nodes. I hope that helps, Stoyan

	I had set Behavior = Custom and CustomNodeType = typeof(cNode) to enable drawing custom nodes. It didn't work. Let me know if you have any other ideas. I will try to troubleshoot.

	The IconNodes sample project sets Behavior and CustomNodeType the same way. Adding a property grid to it shows the new properties of IconNode objects - Label and Icon. Check if your Behavior value doesn't change to DrawShapes or LinkShapes later, e.g. it might reset to LinkShapes if you load a file using DiagramView.Load methods. I hope that helps, Stoyan
