	Hi, I am creating a custom shape node and would like to place texts above the shape node and inside the shape node at the same time. I have looked in the help but haven�t found any way to do this. Is there anyone who could help me? I would also like to place texts above my anchor points, is it possible and how do I do it?

	Hi, You might set the anchors style to Custom and handle the DrawMark event to draw both the point and its text. To display an additional label for a node, either use the 'Additional' custom drawing style and handle the DrawNode event, or attach a Transparent node containing the text to the main node by calling AttachTo. I hope that helps, Stoyan

	Hi, Thanks for the help. I have a couple of questions though. Is there a way to make the anchor points with its text visible always, not only when the mouse pointer is above the node? I�m having trouble making the AttachToNode to work. I have put the code in the DrawNode method. I create a new ShapeNode that contains the additional text, but when I call its AttachToNode method with my original node as in parameter and run it, a nullreferenceexception is thrown, none of the nodes are null, I have a check before the call. An example would be helpful.

	Hi, Set Diagram.ShowAnchors = Always. Atatching a label to a node drawn by the user could look like this, with a bit of C# 3 syntax Code private void siteMap_NodeCreated(object sender, NodeEventArgs e) { var nb = e.Node.Bounds; var label = new ShapeNode { Transparent = true, Locked = true, Text = "label", Bounds = new Rect(nb.X + nb.Width / 2 - 30, nb.Bottom + 2, 60, 20), Font = new Font("Arial", 10, GraphicsUnit.Point) }; var diag = sender as Diagram; if (diag != null) { label.TextFormat.Alignment = StringAlignment.Center; diag.Nodes.Add(label); label.AttachTo(e.Node, AttachToNode.BottomCenter); } } I hope that helps, Stoyan

	How can we edit the newly created label like above at run time?

	Hi, You could call Diagram.BeginEdit(label) after creating the label, or in response to a (double-) click event. I hope that helps, Stoyan

	I have handled that using mouseleftclick event nad it works fine. But when I type longer text I want to increase the width of the label but its size is fixed. Locked proeprty is allowing this but at the same time I do nto want to detach th text from the main label,. How can I increase the size at runtime.

	Set larger label.Bounds or call label.ResizeToFitText().

	label.ResizeToFitText() is working only when the user clicks on it for the second time untill then the text is not displayed completely. I am trying to set its width by catching keyup (enter key) or with mosue lose focus but those events are never firing aeven after setting the focus explicitly.

	Are you calling ResizeToFit after the text is edited? Try calling it from the NodeTextEdited event handler. Stoyan
