Hi,

 

I have a tree control and that contains two databases with tables as tree nodes. I have a requirement to drag couple of tables from these databases (from tree) and drop on them as Nevron shape on Nevron canvas. What is the recommended shape you suggest? (I need to display table columns and data type and PK/FK relation text)

 

After drag and drop of these tables, I need to visually map the fields between tables using Nevron connectors, what type of connector shape can I use?

 

After mapping the fields visually, I need to identify the mapping relationship (which field is mapped with which field between table shapes) by .NET code in the diagram.  How can I do this?

 

Please suggest me the recommended shapes and methodology. I have tried couple of shapes (NErmShape and NTableShape) I could not find out the mapping relationship.

 

Thanks in advance.

Hi Montford,

I understood your requirement. What you have to do is to manually create custom ERM shape for each table, when the user drags it into the drawing view. You can easily do this by using code similar to:

NErmShape shape = new NErmShape(0, 0, 10, 10);
shape.CreateFromTable(dataTable);

Where dataTable is the table that the user has dragged into the drawing view. Next you can provide the user with the ability to connect the tables using Erm connectors.
