I use a SQL statment to select the userid from a user with user.identity.name. This works fine in a aspx page. I can format the id to a string a display it in a label.

SqlCommand intgebruikersid = new SqlCommand("select UserId from aspnet_Users where UserName = '" + User.Identity.Name + "'", conn);

Now, if i want to do exactly the same with another page it wont display the userid in a label. The only difference this other page has, is that it uses a template with a MasterPage file.

I am using asp.net2.0

Thankyou,

You don't need to run a query to get the Id if you use the Membership feature.

You can get the Id from the MembershipUser class.

Use the Membership.GetUser method to get the MembershipUser class for the current logged in user. The property ProviderUserKey will return the User id.

you can try use:

Page.Identity.Name 

in master page or someother pages

Would you please elaborate on that?

I'm trying to retrieve the id of a logged-in user through the Login Name control in VWD2005.
I would like to put the retrieved id in a label on my page so that it can then by inserted together with other product details in my orders table.

This is the code i've been fiddling with:

If User.Identity.IsAuthenticated = False Then
            Server.Transfer("login.aspx")
        End If
        
        If User.Identity.IsAuthenticated = True Then
            
            Dim m As MembershipUser
            
            m = Membership.GetUser()
            Response.Write("ID=" + m.ProviderUserKey.ToString())
            
        End If

 Now I'm getting this error: "Object reference not set to an instance of an object."

I'm new to all this. I just do not know what is means.

Thanks in advance.
