	I have an application that I designed plot by their control which takes information from the database and keep it as an image but when I create a new goal this I am not going to comply because it will read the file where you save. As might make my goal created appears in my diagram store without being loaded again, because I could erase the connectors if it creates again.

	You need to detect when the user draws new items and add corresponding records to your database?

	Stoyan, You commented: I have an application that I designed the chart for its control which takes the information from the database and saves it as an image but when I create a new obj that I am not going to comply because it is going to read the file where you saved. As might make my created node (strategic objectives) appears in my chart that you save without being charged again?, Since I could erase the connectors if it is created again. In my diagram for example, I have 10 nodes (strategic goals), then the relationship through links and then burn it, now I create a new node (from sql server I create a new strategic objectives) when I open the diagram I erased everything else, as I do so that in my chart display the 11 nodes (strategic objectives), I hope I understand. greetings

	I'm afraid I don't understand Do you need to add a record to your database when a node or a link is created? Without deleting some other records?

	Stoyan, Yes, I need to discover what and how I can also record in the database and then change my diagram. I could give you an example in this regard??

	Quote: what I want is that the definitions of links between nodes recorded in the database and then be able to modify If there will be just one link between nodes, as shown on that screenshot, you might add a DestinationID field to the nodes' table. Set the value of that field to the ID of the record that corresponds to the link's Destination node. To make it easier to map nodes to their records in the database, you could assign the value of the ID field to the node's Tag. Then when saving the link information, get the value of DiagramLink.Destination.Tag and assign it to the DestinationID field. If you expect to have a random number of links between nodes, you must create a new table for storing the relations defined through links. You should add OriginID and DestinationID fields, and possibly other fields for the any link properties you'd like to have. Now store the Tag values of the link's Origin and Destination nodes into the OriginID and DestinationID fields. When loading the diagram, first create all nodes and set their Tag to the record's ID field value. Next create links using the Diagram.FindNode(tag) method, which will let you find the nodes corresponding to the respective OriginID and DestinationID. I hope that helps, Stoyan

	Stoyan, Thanks for responding, I see that I got it right. What I do is bring the nodes randomly, I could provide an example to be able to implement? greetings.

	It shouldn't matter in what order you are loading the nodes, as long as you save their record IDs as Tag values, so that later you can find the related nodes when creating a link.

	Diagram.Nodes includes nodes from all DiagramNode-derived types, including ShapeNode. You can get the position of a node through its Bounds property. If you need to access ShapeNode specific properties while enumerating Diagram.Nodes, you will have to type-cast the node variable to ShapeNode. There are Origin and Destination properties in DiagramLink that return the respective node. Again, you will have to cast them to ShapeNode if you need to use ShapeNode-specific properties. I hope that helps, Stoyan

	Stoyan, I could send an example of how record in the database as follows: Save the nodes x, y, w, h when to go again in the diagram is in the last position. Save deniciones nodes through links I would be much obliged greetings

	I have a tag and that tag is concatenated with a description and again if it modifying the description gets lost everything. That there is a solution in this regard. greetings
