Code Snippets

Visual WebGui provides simple way to implement Logon screen.  Adding 'Authentication' element in the web.config file, send the user to the page specified in that element if he/she is not logged on.

<Authentication Mode="Main" Type="Gizmox.WebGUI.Sample.Forms.Logon, Gizmox.WebGUI.Sample" />

Currently the only supported Mode (notice Mode attribute) is Main. In the future we'll also implement Dialog mode.

Jconstantino and rhernandez_64 asked for this feature in this post. Although this feature isn't in our roadmap for the near future, its functionality can be achieved relatively easily. Here are two simple steps you need to take in order to implement a dialog logon screen:

1.     Move all the code in the "Form_Load" method of your main form to new method that will be called after the user successfully logged on. Instead if the user is not logged on you should show a dialog popup screen:

Old code:

private void MainForm_Load(object sender, EventArgs e)
      {
            InitializeData();
            Foo();

}

New code:

private void MainForm_Load(object sender, EventArgs e)
      {

//if user is not logged on - show logon screen
      if (!Context.Session.IsLoggedOn)

{

                  Logon objLogonPopup = new Logon();

objLogonPopup.Closed += new EventHandler(objLogonPopup_Closed);
objLogonPopup.ShowDialog();
}

}

private void FormLoad_AfterLogon()
      {
            InitializeData();
            Foo();
            }

2.     Create a logon form. And set Context.Session.IsLoggedOn (Boolean) accordingly. If user logged on successfully, then close the form. Else alert the user:

private void btnLogon_Click(object sender, EventArgs e)
      {
            Context.Session.IsLoggedOn = (txtPassword.Text == "pass1" &&

txtUsername.Text == "user1");

            if (Context.Session.IsLoggedOn)
            {
                this.Close();
            }
            else
            {
                MessageBox.Show(    "Username or Password inocrrect!",

"Login Faild",

MessageBoxButtons.OK,

MessageBoxIcon.Error);

}

}
