Problem with Login Page

[lorena]

I have a small asp.net app that loads a login page with two textboxes for username and password and a login button. Each textbox has a RequiredFieldvalidator and I use the Page.IsValid for the OnClick event of the Login button.

I also have two hyperlinks on the page so that users can go back to non-login pages.

My problem is that the RequiredFieldvalidator events fire when either hyperlink is clicked and keep the hyperlinks from allowing users to navigate off of the page.

<script language="VB" runat="server">

'Code for the login button

Sub Login_Click(Src As Object, E As EventArgs)

If Page.IsValid Then

Dim strUN as string = txtUN.text

Dim strPW as string = txtPwd.text

Dim strConn as string ="Provider=Microsoft.Jet.OLEDB.4.0;Data Source= " & server.mappath("DB/sf.mdb") & ";"

Dim Conn as New OLEDBConnection(strConn)

Conn.Open()

Dim strSQL as string = "SELECT * FROM info WHERE un = '~' and pwd= 'Val1'"

strSQL = Replace(strSQL,"~", strUN)

strSQL = Replace(strSQL,"Val1", strPW)

Dim Cmd as New OLEDBCommand(strSQL,Conn)

 

'Create a datareader, connection object

Dim Dr as OLEDBDataReader = Cmd.ExecuteReader(System.Data.CommandBehavior.CloseConnection)

 

'Get the first row and check the password.

If Dr.Read() then

If Dr("Pwd").ToString = txtPwd.text and DR("UN").ToString=txtUN.text Then

FormsAuthentication.RedirectFromLoginPage(txtUN.Text, false)

Else

lblLoginMsg.text = "Invalid login attempt."

End If

Else

lblLoginMsg.text = "Login name or Password not found."

End If

Dr.Close

End If

End Sub

Sub tds_img_OnClick(Sender As Object, E As ImageClickEventArgs)

If not Page.IsValid then

FormsAuthentication.SignOut()

Response.Redirect ("http://www.homepage.com")

End If

End Sub

Sub sup_img_OnClick(Sender As Object, E As ImageClickEventArgs)

FormsAuthentication.SignOut()

Response.Redirect ("http://www.homepage.com/sup/welcome.htm")

End Sub

</script>

Is there someway to get around this? Some Page event that I am missing?

Thanks in advance for any help.

Figured it out. All I needed to do was set "CausesValidation" on the image buttons to "False"
