c# - Password control updated in the background does not reflect in the UI in ASP.NET web application -

i have asp.net web application want customize createuser wizard. in user registration workflow, instead of asking users enter password, generating password programmatically , assign password control when being loaded. control disabled , sent notification user. following snippets .aspx , corresponding c# code.

 <asp:textbox id="password" runat="server" cssclass="passwordentry" textmode="password" onload="generaterandompassword" />   protected void generaterandompassword(object sender, eventargs e)     {         textbox pwdtextbox = (textbox)registeruserwizardstep.contenttemplatecontainer.findcontrol("password");          if (pwdtextbox != null)         {             pwdtextbox.text = membership.generatepassword(8, 2);                         }     }
