Problem with Profiles in ASP .NET

[Itarlydar]

I made an ASP .net application which use the asp .net login system. I use the a class which gets some details of the logged in user such as Name, address etc. In the page that the user can change his details i have those commands. If i don't use the commands in the page_load the address changes in the database successfully, but if i use them the database doesnt make the changes in the address. How is it possible? The profileC class uses the Inherits from ProfileBase class\[code\] protected void Page_Load(object sender, EventArgs e) { if (HttpContext.Current.User.Identity.IsAuthenticated) { classes.ProfileC pr = classes.ProfileC.GetProfileC(HttpContext.Current.User.Identity.Name); TxtAddress.Text = pr.UserAddress; } } protected void BtnAdd_Click(object sender, EventArgs e) { classes.ProfileC pr = classes.ProfileC.GetProfileC(HttpContext.Current.User.Identity.Name); pr.UserAddress = TxtAddress.Text; pr.Save(); }}\[/code\]
