	I have a new class and inherit from Shapenode. I have in this class a funktion SetShapeProperties. [code]private void SetShapeProperties() { this.Shape = Shapes.BpmnParallelFork; this.Bounds = new Rect(100, 200, 30, 30); this.Brush = Brushes.LightYellow; this.TextBrush = Brushes.Black; }[/code] I create a Shape like this (constuctor calls SetShapeProperties) [code] MyShape shape = new MyShape(); mydiagram.Nodes.Add(shape);[/code] Due to the ShapeDesigner the BpmnParallelFork has a Textarea beneath the Shape. When i enter a Text in the Shape, i get no text. Neither inside nor outside.

	The text area is defined in terms of percents of the node size, and for a 30x30 pixels node there might not be much space left for the text. You can either define much larger text area for BpmnParallelFork, or use an attached transparent node to display the text. I hope that helps, Stoyan

	Hi Stoyan, yes the shape was to small. When i resize it I get my text. I would like to try defining much larger text area AND a much bigger Textbox to change the text. It's very small for typing a text :) 1. Can I achieve this without an attached label? 2. If yes: Do I have to create a new Shapetemplate or can i define the size/position of the textarea by a property of the BpmnFork Shape? 3. If no: how can I bind the attached label to the node (something like SetBinding(label.Text, node.Text);? Hope you understand my request.

	Hi, It should be possible. For specifying the textbox size, implement the InplaceEditable interface and return larger rectangle from GetEditRect. I think it's relative to the node, a TextBox starting from 0,0 will coincide with the node's top-left corner. For rendering the text, you could either modify Shapes.BpmnParallelFork.TextArea, or overide the ShapeNode.Draw method like this: Code override Draw(DrawingContext dc, RenderOptions ro) { ro.EnableText = false; base.Draw(...); ro.EnableText = true; dc.DrawText(...); } I hope that helps, Stoyan

	Hi Stoyan, it worked very well. I used the GetEditRect Function to specify the textbox and i modified the TextArea as suggested. Thank you very much.
