Protected Sub LoginButton_Click(ByVal sender As Object, ByVal e As System.EventArgs)
        
        
        
        If Membership.ValidateUser(UserName.Text, Password.Text) Then
            ' Log the user into the site 
            FormsAuthentication.RedirectFromLoginPage(UserName.Text, RememberMe.Checked)
        End If
        ' If we reach here, the user's credentials were invalid 
        InvalidCredentialsMessage.Visible = True

    End Sub

Keep your post well-formated. Use BB code tags.

>the username and password is not declared..
It means you haven't place textboxes named "username" and "password". Check the ID property of TextBoxes.

sir, ive already placed the textbox and named them accordingly as below.

Protected Sub LoginButton_Click(ByVal sender As Object, ByVal e As System.EventArgs)
        
        
        
        If Membership.ValidateUser(UserName.Text, Password.Text) Then
            ' Log the user into the site 
            FormsAuthentication.RedirectFromLoginPage(UserName.Text, RememberMe.Checked)
        End If
        ' If we reach here, the user's credentials were invalid 
        InvalidCredentialsMessage.Visible = True

    End Sub

Again!!!
Try to read this -

Your source code must be surrounded with BB code tags.

You had a Login control. Use Login1.UserName and Login1.Password property to access the textboxes.

[chriscross86]

Thank you. It really worked.
I have a problem with this statement as well. it sdays 'name 'InvalidCredentialsMessage' is not declared. please help me solve it

InvalidCredentialsMessage.Visible = True

Protected Sub LoginButton_Click(ByVal sender As Object, ByVal e As System.EventArgs)

If Membership.ValidateUser(Login1.UserName, Login1.Password) Then
' Log the user into the site
FormsAuthentication.RedirectFromLoginPage(Login1.UserName, Login1.RememberMe.checked)
End If
' If we reach here, the user's credentials were invalid
InvalidCredentialsMessage.Visible = True

End Sub
