Hi,

Are you using RegisterItemClass to enable serialization of custom objects in the WinForms app? You should now call RegisterItemClass from the web application too, using the same class IDs to enable loading objects from the custom class.

I hope that helps,

Hi,

The IDs are saved in a static table in the Diagram class, so you might add Global.asax (using the "Global application class" template from the New Item list) and register the class in Application_Start. Otherwise you might check if ((view.Diagram as IItemFactory).ClsidTable.ContainsKey(...)) before calling the Register method in Form_Load.

I hope that helps,
Stoyan

Also, I should note that when I use the flowcharter sample for the Flowchart.NET product, (add in the registeritem code) and load the saved diagram, then I do get the expected result.

Thanks again for your help!

Hello,

Yes, for testing purposes, I have made my custom code very simple (empty) to make sure there aren't any windows specific objects:
Public Class SchematicNote
    Inherits MindFusion.Diagramming.ShapeNode
End Class

This is the same dll reference from both the saving windows application and the loading web application.

Hello,

No, I am using the same build of by custom object dll for saving that I am for loading. There should be no extra data saved with the diagram.

I decided that my custom application had to many factors to make a decent test, so i built a test case from your samples, it gave the same result.. Here is what I did:

I took the IconNodes sample from Flowchart.net, and replaced the reference to IconNode with my custom dll that contains this code:
namespace IconNodes {
public class IconNode : ShapeNode {}
}
I took out the parts that assign an icon so my simplified object would work with the application.
Then, I ran the sample, add some squares and save to file.
Then, I used the Flowcharter sample from Netdiagram, and referenced the same custom dll,
added the registeritemclass code to register my class, ran the sample and loaded the file I saved.
It comes up as blank, the squares do not show up. If I use the IconNode sample and load the diagram, they do show up.

Thanks again!
