Sharepoint Web Part with multiple Interface types

Question

0.00/5 (No votes)

See more:

I have created three small Sharepoint web parts (using VSExtensions 1.2). Each webpart can work independently. How can I arrange that webpart B (which contains a datagrid) consumes a parameter (single value, text) from Webpart A and can provide a row parameter to webpart C?

E.g. :
webpart A: retrieves project data (No. and name) from a database. Sends the project number as a parameter to Webpart B.
webpart B: retrieves project tasks (displayed in datagridview, not editable) from a database for the project number consumed from webpart A. Upon user action (button-click) it sends row data (project number and task number) to webpart C.
webpart C: consumes project task information from webpart B, and offers "editable" data to the user.

Thanks for your help.

In a way yes, and that is working. (Webpart A provides text value to webpart B or call it: B consumes from A.) But the question is, how can I make sure B consumes a single text from A, but is able to provide a "data row" to C?

Have B consume from A and C consume from B. It's up to you, as the developer, to provide the proper interfaces and methods to make this happen.
