No. Web User Controls should do the job just ok. Maybe you are accessing those
properties at wrong time. Try saving those prop values inside ViewState like:

public string userName
{
get { return (string)ViewState["accessUserName"]; }
set { ViewState["accessUserName"] = value; }
}

it's still make me problems.
here is the header.ascx.cs:

private void Page_Load(object sender, System.EventArgs e)
userObj.generateUser()
bla...

public string name
{
get
{
return userObj.name;
}
}

Rename your property to userName or something else, because your Control already
has a propery Name... I think...

i already changed it...
still dont give me the value.It's empty

Have you debugged it and stepped into...

your code suggests you have your Properties defined in your page
load ?? that's wrong .. define them in your variables declaration.

don't know if this will make a difference

private void Page_Load(object sender, System.EventArgs e)
userObj.generateUser()
bla...

public string name
{
get
{
return userObj.name;
}
}

just unzip it to your Inetpub/www folder and create a virtual dir for it.

of course i defined the properties  outside the page_load

public string name
> {
> get
> {
> return userObj.name;
> }
> }

anyway it's not working...
thanks a ton about the zip - i will look at it
