Question

Get membership email in HTML Datalist

Asked by: wilcor14

In the itemtemplate of a datalist, I am trying to get access to the email address using membershipprovider in ASP.net 2.0

Why will something like this not work? (See code below)

It's giving me the error:
The provider user key supplied is invalid.  It must be of type System.Guid.
Parameter name: providerUserKey


Thanks for your guidance.


<ItemTemplate>
              <%#Membership.GetUser(Container.DataItem("UserID")).Email%>
   </ItemTemplate>

Try to change it to this:

<%#Membership.GetUser(Container.DataItem("UserID").ToString()).Email%>

Also, you are using VB.NET, right?

 

by: wilcor14Posted on 2009-10-19 at 11:10:13ID: 25607562

Yes, I'm using vb.net 2.0

I tried that but get this error:

Object reference not set to an instance of an object. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.

 

by: Omego2KPosted on 2009-10-19 at 11:21:23ID: 25607665

Ah, so Container.DataItem("UserID") is null, or in VB.NET's case "Nothing". So Try this:

You would want to create your own function as such:
Public Function GetValue(ByVal dataItem As String) As String
      If dataItem Is Nothing Then Return ""
       
      Return Membership.GetUser(dataItem.ToString()).Email
End Function

<%# GetValue(Container.DataItem("UserID")) %>

Omega2K,

that looks like it would solve the issue if the emailaddr are not set but still getting

Object reference not set to an instance of an object.

 

by: Omego2KPosted on 2009-10-19 at 11:48:13ID: 25607874

Container.DataItem("UserID") is null and is not set.

Where are you getting object not set to an instance of an object in the method?

Omego2K,
