[VWD 2005] Redirection from login page

**paulorton** · Mar 29th, 2008, 11:59 AM

I'm not doing very well here...

Default.asx displays, user clicks on LoginStatus control, login.aspx displays, user fills in details, user gets returned to default.asps despite presence of DestinationPageUrl="~/MainPage.aspx" in code.

Default.aspx, login.aspx and mainpage.aspx are all in the same folder.

I'm clearly doing something very stupid!

hi,
can u figure out your folder solution explorer strucure ....

**mendhak** · Mar 29th, 2008, 12:54 PM

In the LoggedIn event of this Login control is User.Identity.IsAuthenticated = True?

**paulorton** · Mar 29th, 2008, 01:23 PM

No, there's nothing in the code for this event (if I'm looking in the right place:

Partial Class Default2
Inherits System.Web.UI.Page

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

End Sub
End Class

And, of course, the app has amazingly now decided to work (but only on the local machine!!!).

**mendhak** · Mar 29th, 2008, 01:34 PM

According to MSDN, you should have it. You are doing this on the page with the Login control, right?

Code:

Sub OnLoggedIn(ByVal sender As Object, ByVal e As EventArgs)
    SiteSpecificUserLoggingMethod(Login1.UserName)
End Sub

You'll notice that it's looking at Login1.UserName, another point to look at perhaps.

**paulorton** · Mar 29th, 2008, 05:58 PM

Thanks. I've looked at the MSDN link and added some of the code to my login.aspx which now looks like this:

Code:

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="login.aspx.vb" Inherits="Default2" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<script runat="server">
Sub SiteSpecificUserLoggingMethod(ByVal UserName As String)
    ' Insert code to record the current date and time
    ' when this user was authenticated at the site.
End Sub

Sub OnLoggedIn(ByVal sender As Object, ByVal e As EventArgs)
    SiteSpecificUserLoggingMethod(Login1.UserName)
End Sub
</script>

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <title>Untitled Page</title>
    <link href="default.css" rel="stylesheet" type="text/css" />
</head>
<body>
    <form id="form1" runat="server">
    <div>
        &nbsp;<asp:Login ID="Login1" runat="server" style="left: 312px; position: relative; top: 190px" DestinationPageUrl="~/MainPage.aspx">
        </asp:Login>    
    </div>
    </form>
</body>
</html>

This hasn't made any difference - things behave as they should here (ie. mainpage.aspx loads) but on the server completing the login successfully returns me to default.aspx

BTW, I put a breakpoint on the line

Code:

SiteSpecificUserLoggingMethod(Login1.UserName)

but it wasn't executed (even though the login was successful). Why would that be (or have I misunderstood how debugging works in VWD - I'm only used to VB6)?

**mendhak** · Mar 29th, 2008, 06:20 PM

Because you haven't specified whether that event should be hit or not.

Code:

<asp:Login ID="Login1" runat="server" style="left: 312px; position: relative; top: 190px" DestinationPageUrl="~/MainPage.aspx" OnLoggedIn="OnLoggedIn">
</asp:Login>

</asp:Login>

But why should I have to? Why isn't it sufficient to set the DestinationPageUrl property? I thought these controls were meant to hide a lot of background code. I can see that the LoggedIn event could be useful for all sorts of things but why does giving DestinationPageUrl a value mean that I have to write extra code for it to work?

Its value is true on my local machine but I have no idea if it's the same on the remote server (which is where the problem now is, it would seem).
Is there a way of displaying the value of this property online?

You don't. This is for testing purposes to see if the user does actually log in. A crude way of tracing things.

Yes. Try doing a Response.write of that value, either on the same page or the destination page load event. The 'value' should show up somewhere near the top of the page in an ugly font. Remove it soon afterwards.

**paulorton** · Mar 30th, 2008, 01:08 PM

OK, did that and Response.Write(User.Identity.IsAuthenticated) returned "true".

In other words the user successfully logs in but the setting of login control's DestinationPageUrl property to "~/MainPage.aspx" isn't working - the user is returned to default.aspx (but only on the remote server - it works fine here).

**mendhak** · Mar 31st, 2008, 02:57 AM

Alright, get rid of that testing code you had. So you've now confirmed that the user is in fact logged in on the remote server as well, but the DestinationPageUrl is not respected. Under the <authentication> node in your web.config, you will see a <forms> node. Set a defaultUrl property for it to MainPage.aspx

**paulorton** · Mar 31st, 2008, 03:11 AM

Thanks, done that but I'm still redirected to default.aspx

Just to confirm again, here is the code in login.aspx :

Code:

<asp:Login ID="Login1" runat="server" style="left: 312px; position: relative; top: 190px" DestinationPageUrl="~/MainPage.aspx" OnLoggedIn="OnLoggedIn">
        </asp:Login>

And MainPage.aspx is in the same folder on the server as all the pages I have so far created.

**paulorton** · Mar 31st, 2008, 03:13 AM

Plus I have this (also in login.aspx) :

Code:

<script runat="server">
Sub SiteSpecificUserLoggingMethod(ByVal UserName As String)
    ' Insert code to record the current date and time
    ' when this user was authenticated at the site.
End Sub

Sub OnLoggedIn(ByVal sender As Object, ByVal e As EventArgs)
    SiteSpecificUserLoggingMethod(Login1.UserName)
End Sub
</script>

**mendhak** · Mar 31st, 2008, 04:33 AM

Like you said earlier, you shouldn't need this extra code. We used that to confirm that the user was indeed logged in, and he is.

So get rid of

OnLoggedIn="OnLoggedIn"

and

Code:

<script runat="server">
Sub SiteSpecificUserLoggingMethod(ByVal UserName As String)
    ' Insert code to record the current date and time
    ' when this user was authenticated at the site.
End Sub

Sub OnLoggedIn(ByVal sender As Object, ByVal e As EventArgs)
    SiteSpecificUserLoggingMethod(Login1.UserName)
End Sub
</script>

Could you do what I mentioned in post 13? In the <forms> node, set the defaultUrl attribute.

**paulorton** · Mar 31st, 2008, 04:47 AM

OK, OnLoggedIn="OnLoggedIn" now deleted and I had already set the DefaultURL property to "MainPage.aspx" - still no joy though...

**mendhak** · Mar 31st, 2008, 02:36 PM

I'm at a loss here. Wouldn't be possible for you to upload a sample would it? Can you reproduce the issue in a new project?

**paulorton** · Apr 1st, 2008, 03:43 PM

I am using Access for membership data. MainPage.aspx (the page I am not being redirected to) also loads data from an Access database - if that's relevant. Here's all the code I can see that's relevant (there's nothing in the code behinds).

**paulorton** · Apr 4th, 2008, 09:37 AM

Tried the following code in default.aspx.vb :

Code:

Protected Sub Page_LoadComplete(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.LoadComplete
        If User.Identity.IsAuthenticated Then
            Response.Redirect("MainPage.aspx")
        End If
    End Sub

(If you recall, MainPage is not being loaded after a user logs in and user gets returned to default.aspx).

This code does indeed attempt to load MainPage but the load fails, flagging a "System.Data.OleDb.OleDbException" (the page has a gridview that loads data from an Access database).

I don't suppose it's of any use but here is the stack trace :

Code:

Any idea why the gridview isn't working (it does on my local machine)? Could this be the reason why MainPage wasn't loading when I first started this thread?

**paulorton** · Apr 4th, 2008, 09:53 AM

It's the gridview that's causing all the trouble! If I remove it MainPage loads once the user has logged in.

Here's the code I was using for it - as I said it works fine here :

Code:

<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
    <asp:GridView ID="GridView1" runat="server" DataSourceID="AccessDataSource1" AutoGenerateColumns="False">
        <Columns>
            <asp:BoundField DataField="DateOfWork" HeaderText="DateOfWork" SortExpression="DateOfWork" />
            <asp:BoundField DataField="Worksheet" HeaderText="Worksheet" SortExpression="Worksheet" />
            <asp:BoundField DataField="NumQuestions" HeaderText="NumQuestions" SortExpression="NumQuestions" />
            <asp:BoundField DataField="Try" HeaderText="Try" SortExpression="Try" />
            <asp:BoundField DataField="NumSheets" HeaderText="NumSheets" SortExpression="NumSheets" />
            <asp:BoundField DataField="Errors" HeaderText="Errors" SortExpression="Errors" />
            <asp:BoundField DataField="Percentage" HeaderText="Percentage" SortExpression="Percentage" />
            <asp:BoundField DataField="Time" HeaderText="Time" SortExpression="Time" />
            <asp:BoundField DataField="HomeComment" HeaderText="HomeComment" SortExpression="HomeComment" />
            <asp:BoundField DataField="Parent/StudentComment" HeaderText="Parent/StudentComment" SortExpression="Parent/StudentComment" />
        </Columns>
    </asp:GridView>
    <asp:AccessDataSource ID="AccessDataSource1" runat="server" DataFile="Carmarthen.mdb" SelectCommand="SELECT * FROM [M_AamirAbdullah]"></asp:AccessDataSource>
</asp:Content>

**mendhak** · Apr 4th, 2008, 02:44 PM

Not sure I understand. Had I seen the stacktrace earlier (I just saw it right now), then we'd know that it was indeed database related. How was the gridview causing the problem though?

When I started this thread no exception was caused when the user went back to default.aspx instead of to MainPage.aspx - the app just behaved as if everything was working fine. That's why you couldn't understand what was causing the problem.

The exception is only generated by

Code:

Response.redirect ("MainPage.aspx")

which I only added today in an attempt to try to find another way to get MainPage loaded.

**mendhak** · Apr 6th, 2008, 11:08 AM

So it wasn't aliens, which was going to be my next suggestion. Thanks for saving me from the embarrassment.

**paulorton** · Apr 6th, 2008, 02:12 PM

Do you have any idea what's going wrong with the gridview? I assume it can't talk to the database for some reason...

**mendhak** · Apr 6th, 2008, 03:00 PM

Start a new thread about your gridview since you'll be able to get more people answering your brand new gridview question (it being a new thread, new perspective, etc)
