Hello,

I'm bravely writing my first umbraco user control (umbraco.tv video was a great help) which will eventually be a member search.

I'm able to fetch all the members and some of their built-in values like Email, but I can't figure out how to use the getProperty method to get a custom member field. Seems like it should be easy from googling examples, but i get an 'Object reference not set to an instance of an object' error with this code:

Code:

protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
ResultsField.Text = "Type above and go";
}

foreach (umbraco.cms.businesslogic.member.Member m in
umbraco.cms.businesslogic.member.Member.GetAll)
{
ResultsField.Text += m.getProperty("RegionServed").Value; // throws the error
ResultsField.Text += m.Email; // works fine
}

}

I'm sure 'RegionServed' is the correct alias of my Member property.

Any ideas? Be nice, I'm a former PHP coder and so far C# is a cruel mistress :)

Hi Andrew,

Without knowing the properties for your member type, it sounds like either the alias name is wrong, or the property doesn't exist.

A simple way to identify this is to get the Property object first, before calling the .Value:

Code:

foreach (Member m in Member.GetAll)
{
  Property p= m.getProperty("RegionServed");
  if (p != null)
  {
      ResultsField.Text += p.Value;
      ResultsField.Text += m.Email;
  }
  else
  {
      // do something with members that don't have the "RegionServed" property
  }
}

Hope this helps.

Cheers,
- Lee

PS. I saw your reply on the other forum topic about Member Search. I'll get around to posting some code soon; (got a project deadline for Friday - so working around the clock until then) Boo hoo!

Thanks, that worked perfectly - the RegionServed property simply wasn't set for one of my Members, so .NET threw an error when I tried to access its value.
