Question

I am using C# and .Net I need to redirect a user to a specific URL when the authentication (using Membership providers) failed.

I was thinking to use

RedirectToLoginPage(String)

From MSDN: Redirects the browser to the login URL with the specified query string

But I need to change the URL.

Example of use:

 if (!Membership.ValidateUser(userName, password))
    {// do smt here}  

Any other idea how to solve it?

For me this really works

aspx:

Username: <br />
<asp:TextBox runat="server" ID="txtUserName"></asp:TextBox>
<br />
Password: <br />
<asp:TextBox runat="server" ID="txtPassword" TextMode="Password"></asp:TextBox>
<br />
<asp:Button runat="server" ID="btnLogin" Text="Login" onclick="btnLogin_Click" 
    style="height: 26px" />

Code behind:

protected void btnLogin_Click(object sender, EventArgs e)
{
   string username = txtUserName.Text.Trim();
   string password = txtPassword.Text.Trim();

   if (Membership.ValidateUser(username, password))
   {
     //...             
   }
   else
   {
       Response.Redirect("Hello.aspx");
   }
}
