How to set an interest on or off for a contact (data layer)

• 2 minutes to read

You can search for an interest and then set the interest to true or false. Here, we use the ContactInterestHelper.

Code

using SuperOffice;
using SuperOffice.CRM.Entities;
using SuperOffice.CRM.Lists;

using (SoSession newSession = SoSession.Authenticate("sam", "sam"))
{
  //Setting the Interest name to be searched
  string searchIntrsName = "Sams Interests";

  //Retrieve a Contact
  Contact newContact= Contact.GetFromIdxContactId(10);

  //Search and find the contact interests by interest name
  ISoListItem newIntrstItm = newContact.InterestHelper.RootItems.Find(delegate(ISoListItem ISOLstItm)
  {
    return ISOLstItm.Name.Equals(searchIntrsName,StringComparison.InvariantCultureIgnoreCase);
  }
  );

  //Check whether the Interest has been found
  if (newIntrstItm != null && newIntrstItm.Id > 0)
  {
    //Sets the Interest to true or false
    newContact.InterestHelper.SetItemSelection(newIntrstItm.Id, true);
  }
}

Walk-through

The Find method available through the Contact class’s InterestHelper.RootItems can be used to make our search.

ISoListItem newIntrstItm = newContact.InterestHelper.RootItems.Find(delegate(ISoListItem ISOLstItm)
{
  return ISOLstItm.Name.Equals(searchIntrsName,StringComparison.InvariantCultureIgnoreCase);
}
);

The method returns an ISoListItem and requires a delegate that defines the element for which we should search to be passed into the method. The method then returns any interest that matches our search interest by using the Equals method.

Next, we move on to setting the interest to true or false. To do this we use the SetItemSelection method available ContactInterestHelper class. The method requires the interest ID and the new selection status (true or false) to be passed.
