a few years ago I created a connectable custom webpart based on a OSIsoft documentation. This webpart was able to make connection between my custom webpart and the OSIsoft PI Trend webpart.
In those days Sharepoint 2007 was the current version. Now SharePoint 2013 is the current one.
Is there an OSIsoft documentation available where is described how to create a connectable SharePoint 2013 WebPart in combination with SharePoint 2013? In Visual Studio some information is displayed that IRowProvider shouldn't be used because it is obsolete.
In advance thank you very much for your support.
