Need help with Login Control

[Learner]

Hello,

I am trying to get the UserID from the aspnet_users from aspnetdb
database with the below code snippet.



Protected

Sub Login1_LoggedIn(ByVal sender As Object, ByVal e As
System.EventArgs) Handles Login1.LoggedIn

Dim UserID As String = String.Empty

Dim ManufacturerID As Integer
UserID =
Membership.GetUser(Page.User.Identity.Name).ProviderUserKey.ToString


Dim BL As New GroundingBL
ManufacturerID = BL.GetManufacturerIDFromUsers(UserID)


End Sub


As you see I am using Login1_LoggedIn event, to me, that means the user
is already logged in. But for some reason the value of
page.User.Identity.Name is empyt ("") when I debug. Am I using the
wrong event here? When I debug all through I get the below error

*************************************************************

****************************************************************

I need the UserID value and should put in a session variable and should
be used to pull other data values in our database based on this UserID
value.

Could some one please help me here and suggest me the right event that
fires off after user completely logged in.



Thanks

For on your ManufactureID is an Int value.
And the UserId of the aspnet_Users table is a Guid();

But to get that value form the table you have to do the following.

Try this.

Guid userID = new Guid();
userID = (Guid)Membership.GetUser(_userName).ProviderUserKey;


string someId = userID.ToString();

Of course this is in C# so you will have to convert to VB

Hope this helps.
