[CLOSED] Call an AJAX function from the key map extension...
How do I call my ajax function when the enter key is pressed on this page?

<script runat="server">
Protected Overloads Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
End Sub
<AjaxMethod()> _
Protected Sub btnLogin_Click(ByVal sender As Object, ByVal e As AjaxEventArgs)
'get the users credentials
Dim username As String = Me.txtUsername.Text
Dim password As String = Me.txtPassword.Text
'do we want to persist the cookie after browser close
Dim rememberme As Boolean = chkRememberMe.Checked
'Dim cs As String = Helpers.Connection.ConnectionString(Request.ServerVariables("SERVER_NAME"))
'Dim ds As DataSet = SqlHelper.ExecuteDataset(cs, "spLogin", username, password)
'If ds.Tables(0).Rows.Count > 0 Then
If True Then
'we have an authenticated user
WindowLogin.Hide()
Else
Me.WindowLogin.Title = "Login Unsuccessful - Please Try Again"
End If
End Sub
