Error when trying to loop through Form Controls

[oochr1soo]

I have a current form that has some code on the Submit_Click event and I recently added a Class reference at the top to validate the controls and if they fail highlight them. But now when i run the form it fails when it runs the following code:

Sub Submit_Click(sender As Object, e As EventArgs)
If Page.IsValid then

Dim myForm As Control = Page.FindControl("security")
Dim ctl1 As Control

For Each ctl1 In myForm.Controls
If ctl1.GetType().ToString().Equals("System.Web.UI.WebControls.TextBox") Then
If CType(ctl1, TextBox).text = "" Then
AutoEmail1.Ignorefieldlist += CType(ctl1, TextBox).id+","
Else
CType(ctl1, TextBox).Text = "I Ran"
End If
End If
Next ctl1
AutoEmail1.Initiate()
End if
End Sub


It fails specifically on the For Each line. The error i get is:

Object reference not set to an instance of an object.
Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.


Is there a different way i have to write the syntax now for looping through the controls if im using a class to do some validation of them?

Sounds like this line is failing:
Dim myForm As Control = Page.FindControl("security")

Are you sure that FindControl is returning a reference to your form?

EDIT: I fixed it, i had to add ID="myformname" to the form tag..
