Hi Balaji,
Thanks for evaluating Syncfusion products.
We have used SQL server 2005 express edition to create the sample for you.
Here are the details about your query,
Saving diagram into Database
-------------------------------------------------
You can save the node objects into database. Please follow the steps below for this.
1) First save the diagram in EDD format.
1) Convert diagram(EDD) into bytes using Stream.
2) Insert bytes into table column.
You can use varbinary(max) datatype for inserting diagram since diagram file size will be large to access.
Similarly you can load the diagram from database by reading it from Stream.
Please refer the working sample and let us know if you still face any issues.

You can follow up any other queries in DirectTrac itself (in which you had created an incident earlier).
Regards,
Fahad
