Hi All,

I'm having an issue when saving a diagram using method SaveToFile.

I've created a class called DialogNodeView which extends class TableNode. I'm registering this class using the following code:

[code]Diagram.RegisterItemClass(typeof(DialogNodeView), "custom:DialogNodeView", 1);[/code]

The method "SaveToFile" works fine, it generates the file with no problems. Also, when I call "LoadFromFile" the diagram is loaded correctly and the DiagramNodeView instances are in their correct position. However, I'm not being able to move these instances neither create links from them or to them. It looks like the node is locked, but the Locked property is set to false.

I'm able to insert new nodes in the diagram and move them freely, so the diagram is not locked.


I've investigated a little further and discovered that the "Parent" property of the DiagramNodeView instances that have been loaded from the file are in null.


Should I do something else, in order to make this work?


Thanks
Diego

Hi Stoyan

Thanks for your prompt response.

This is the class's default constructor:

[code]public DialogNodeView()

: this(new DialogNodeViewStyle())
{
}[/code]

The constructor that has the DialogNodeViewStyle parameter calls to the base constructor:
[code]public DialogNodeView(DialogNodeViewStyle nodeStyle) : base()
{
FormatTable();

this.NodeStyle = nodeStyle;
this.Refresh();

this.DoResize(_nodeStyle.DefaultWith, this.CaptionHeight);
}[/code]

I'm not overriding the SaveTo / LoadFrom methods.

Anyway, I'm sending the class code in a few minutes.

Thanks
Diego
