Can you post your exact code? The error message seems to suggest you implemented it differently....

this is the code in the .cs file :

using System;
using System.Web;
using System.Web.UI;

namespace Osfp.Web.GlobalEvents
{
publicclassbgclass : IHttpModule
{
publicvoid Init(HttpApplication context)
{
context.PreRequestHandlerExecute += newEventHandler(this.app_PreRequestHandlerExecute);
}
privatevoid app_PreRequestHandlerExecute(object Sender, EventArgs E)
{
Page p = HttpContext.Current.Handler asPage;
if (p != null)
{
ProfileCommon pb = (ProfileCommon)HttpContext.Current.Profile;
p.Theme = pb.Theme;
HttpContext.myContext = HttpContext.Current;
myContext.Response.Redirect(myContext.Request.Url. ToString());

}
}
publicvoid Dispose()
{
}
}
}

There's a dot between HttpContext and myContext that shouldn't be there. So you need to change this:

HttpContext.myContext = HttpContext.Current;

to this:

HttpContext myContext = HttpContext.Current;

i think is not the right place to paste that code...
when i run it, is tring to load but is does not.
anu other idea?

I am sorry. This is not the right place indeed. This is where the theme is applied from the profile. With this code there, you'll end up in a loop.

Instead, move it to the page where you set the profile based on the current DropDownList......

Sorry for the confusion....

you mean in aspx.c#?
using System;
using System.Web;
using System.Web.UI.WebControls;

partial class FanClub : System.Web.UI.Page
{
private void Page_Load(object sender, System.EventArgs e)
{
if (!Page.IsPostBack)
DisplayProfileProperties();
}
protected void btnCancelChanges_Click(object sender, System.EventArgs e)
{
DisplayProfileProperties();
}
protected void btnSaveChanges_Click(object sender, System.EventArgs e)
{
Profile.Theme = ((DropDownList)FCLoginview.FindControl("ThemeList" )).SelectedValue;
Profile.Name = ((TextBox)FCLoginview.FindControl("txtName")).Text ;
Profile.Address = ((TextBox)FCLoginview.FindControl("txtAddress")).T ext;
Profile.City = ((TextBox)FCLoginview.FindControl("txtCity")).Text ;
Profile.County = ((TextBox)FCLoginview.FindControl("txtCounty")).Te xt;
Profile.PostCode = ((TextBox)FCLoginview.FindControl("txtPostCode")). Text;
Profile.Country = ((TextBox)FCLoginview.FindControl("txtCountry")).T ext;
Profile.Mailings = ((CheckBox)FCLoginview.FindControl("chkMailing")). Checked;
Profile.Email = ((TextBox)FCLoginview.FindControl("txtEmail")).Tex t;
Profile.MemberName = ((TextBox)FCLoginview.FindControl("txtAlias")).Tex t;
Server.Transfer(SiteMap.CurrentNode.Url);
}
protected void FCLoginview_ViewChanged(object sender, System.EventArgs e)
{
DisplayProfileProperties();
}
private void DisplayProfileProperties()
{
TextBox NameBox = (TextBox)FCLoginview.FindControl("txtName");
if (NameBox != null)
{
((DropDownList)FCLoginview.FindControl("ThemeList" )).SelectedValue = Profile.Theme;
((TextBox)FCLoginview.FindControl("txtName")).Text = Profile.Name;
((TextBox)FCLoginview.FindControl("txtAddress")).T ext = Profile.Address;
((TextBox)FCLoginview.FindControl("txtCity")).Text = Profile.City;
((TextBox)FCLoginview.FindControl("txtCounty")).Te xt = Profile.County;
((TextBox)FCLoginview.FindControl("txtPostCode")). Text = Profile.PostCode;
((TextBox)FCLoginview.FindControl("txtCountry")).T ext = Profile.Country;
((CheckBox)FCLoginview.FindControl("chkMailing")). Checked = Profile.Mailings;
((TextBox)FCLoginview.FindControl("txtEmail")).Tex t = Profile.Email;
((TextBox)FCLoginview.FindControl("txtAlias")).Tex t = Profile.MemberName;
}
}

}
if so, in which procedure?

I don't have this book so I don't know this site, but you could try it instead of the Server.Transfer line. E.g. replace:

Server.Transfer(SiteMap.CurrentNode.Url);

with

Response.Redirect(Request.Url.ToString());

i paste that code into the btnSaveChanges function and worked.
it only happens when i press the save button. any other idea?

Imar · January 20th, 2009, 01:22 PM

Because this code is only triggered when you click the Save button:

protected void btnSaveChanges_Click(object sender, System.EventArgs e)
{
...
}

What would you like to happen and when?

well it does what i was expecting. when i press it, it changes the background.
but it would be more interesting to happened without pressing the button.
