Validators not Validating

Would anyone know why the validations on the page below wouldn't work. I am going through a book and learning and for some reason when I put in the last subroutine to insert the record the validation checks on the controls on the form no longer work.

<%@ Import Namespace="System.Data.SqlClient" %>
<title>The Intranet Site</title>
<script runat="server" language="VB">
Dim objConn As New SQLConnection("Server=XXXXXXX; database=Dorknozzle; uid=XXXXXXX; Pwd=XXXXXXXX;")
Dim objCmd As SQLCommand
Dim objRdr As SQLDataReader 

Sub Page_Load()
 If Not IsPostBack Then
 objCmd = New SQLCommand("Select * From HelpDeskCategories", objConn)
 objRdr = objCmd.ExecuteReader()
 ddlCategory.DataSource = objRdr
 ddlCategory.DataValueField = "CategoryID"
 ddlCategory.DataTextField = "Category"
 objCmd = New SQLCommand("Select * From HelpDeskSubjects", objConn)
 objRdr = objCmd.ExecuteReader()
 ddlSubject.DataSource = objRdr
 ddlSubject.DataValueField = "SubjectID"
 ddlSubject.DataTextField = "Subject"
  End If
End Sub

Sub SubmitHelpDesk(s As Object, e As EventArgs)
    objCmd = New SQLCommand("INSERT INTO HelpDesk (EmployeeID, StationNumber, CategoryID, SubjectID, Description, StatusID)" & _
 "VALUES (@EmployeeID, @StationNumber, @CategoryID, @SubjectID, @Description, @StatusID)", objConn)
 objCmd.Parameters.Add("@EmployeeID", 5)
 objCmd.Parameters.Add("@StationNumber", txtStationNum.Text)
 objCmd.Parameters.Add("@CategoryID", ddlCategory.SelectedItem.Value)
 objCmd.Parameters.Add("@SubjectID", ddlSubject.SelectedItem.Value)
 objCmd.Parameters.Add("@Description", txtDescription.Text)
 objCmd.Parameters.Add("@StatusID", 1)
End Sub

Surround the code in your SubmitHelpdesks routine with:

If IsValid
End If

It might be that the client side validation isn't working because the validator controls don't render client script for the specific browser (I've seen this happen on certain FireFox versions).

So checking the Page's IsValid property is always recommended practice.

I changed the code as requested... and it is working as should now. Could you explain why it didn't work as explained in the book I am using for learning. Just hoping to learn more.

Thanks for all your help!

Web form and a gridview on the same page with data validators
I have a form where a user can submit a new customer and directly below that is a gridview where they can view the customer they just submited plus their other customers they have submited in the past. Now this gridview has the edit/update property so the user can modify their customer information. The whole idea is to have 1 single page where a user can do everything they need to without having to be linked to another page. On this page we can submit new customer info and view the status/info of existing customers and edit that info as needed. So far that works fine. I can submit the new c...

validate Textbox in Web User Control from web form?
ASP.NET 2.0 I have a web user control that contains a textbox.  I need to add some validation (like requiredfieldvalidator, comparevalidator, etc). I would normally add the validator to my web user control by placing the validator next to my textbox.  However, I need the validation message somewhere else on my web form, not near the user control. So how would I associate a validation control on my web form with the text box inside my web user control?  Can this be done; any alternatives out there? Thanks!   The error message should occur wherever you place the vali...

Hi, is it possible to use validation contorls with Javascript disabled in the client browser. If not, what are the alternatives? Many thanks Gareth Sure, it works fine.

Defaultbutton and Validators causing form to submit when it is not valid.
In Internet Explorer, when you have a single textbox, a defaultbutton on the form, and a validator, by pressing enter in the textbox the first time (if it is invalid), the validator fires and the form doesn't submit.  However, this sets __defaultFired to true, therefore the next time you click enter, even though the textbox is not valid, the page submits.  In this case, the page_load executes and ispostback is true, however the button onclick server side function does not fire. I have included an aspx page below that experiences this bug.  The bug can be witnessed by opening ...
