Store the User ID and password in variables. After matching the entered credentials, user should get navigated to the welcome.aspx page with message “Welcome Mr./Mrs____”.
Answer:
Introduction:
Here, we create a ASP.NET login page which can accept username and password from the user and validate it.
If username and password match, the login page redirects to welcome.aspx page and displays the welcome message, else it throws an error message.
The username and password are stored in the local variable in page. We will use the VB language to develop this application.
Login-page.aspx
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<script language="VB" runat="server">
Private Sub Page_Load(sender As Object, e As EventArgs)
If Request.RequestType = "POST" Then
Dim userid As String = Request.Form("txtUserid")
Dim password As String = Request.Form("txtpwd")
If userid = "matrix" And password = "12345" Then
Response.Redirect("welcome.aspx")
Else
lblStatus.Text = "Invalid userid or password!"
End If
End If
End Sub
</script>
<form id="f1" method="post" runat="server">
<fieldset style="width:280px; background-color:aqua">
<legend>Login</legend>
<table>
<tr>
<td>User ID:<font color="#cc0000">*</font></td>
<td><asp:TextBox ID="txtUserid" runat="server"></asp:TextBox><br /> </td>
</tr>
<tr>
<td>Password:<font color="#cc0000">*</font></td>
<td><asp:TextBox ID="txtPwd" runat="server" TextMode="Password"></asp:TextBox><br /></td>
</tr>
<tr>
<td> </td>
<td><asp:Button ID="btnLogin" runat="server" Text="Login" /></td>
</tr>
<tr>
<td> </td>
<td><asp:Label ID="lblStatus" runat="server" Text=""></asp:Label></td>
</tr>
</table>
</fieldset>
</form>
</body>
</html>
Output:
Login Screen
Wrong userid or password
Correct userid and password (welcome page)
