Custom Validator not Validating

Colonel Angus · April 8th, 2004, 08:20 AM

I am using a custom validator to check the sum of 2 values entered into textboxes. In the HTML, I have the onServerValidate set to my Handler, "CustomValidator1_ServerValidate"

The handler goes like this:
Protected Sub CustomValidator1_ServerValidate(ByVal source As System.Object, ByVal args As System.Web.UI.WebControls.ServerValidateEventArgs) Handles CustomValidator1.ServerValidate
         If Not txtHour.Text Is System.DBNull.Value And Not txtHourTenths.Text Is System.DBNull.Value Then
            If IsNumeric(txtHour.Text) And IsNumeric(txtHourTenths.Text) Then
                If (CInt(txtHour.Text) + CInt(txtHourTenths.Text)) = 0 Then
                    CustomValidator1.IsValid = False
                End If
            End If
        End If
    End Sub

This never produces the desired result - if both textboxes are not NULL, are numeric and add up to zero, then the validator message should be displayed.

Is there a flaw with my implementation?

Thanks in advance

Try using 'Is Nothing' instead of 'Is System.DBNull.Value'.

I forget which to use and in which case but it's worth a try.

That had no effect - I believe Nothing is an object reference as opposed to a value.

Hi there,

If txtHour is a valid TextBox, and its Text property is empty, then it will return an empty string, and not nothing or null. So, you can check for the Length of the string:

Code:

If txtHour.Text.Length > 0 Then
  If IsNumeric(txtHour.Text) And IsNumeric(txtHourTenths.Text) Then
    If (CInt(txtHour.Text) + CInt(txtHourTenths.Text)) = 0 Then
      CustomValidator1.IsValid = False
    End If
  End If
End If

HtH,

I see where you are going with length > 0.

I tried it, and my validator still doesn't show up on postback and both textboxes have 0 in them. Is there some fundamental principle of using a CustomValidator server-side function that I am not taking into account?

For what it's worth, I wrote this reply while listening to Love Is Green by Jeff Beck (from the album Wired)

He, did you write your own "Query WinAmp Web service" as well?? ;)

Can you post the code for the entire page? Maybe there is something else why the code doesn't work.
Does the CustomValidator1_ServerValidate get hit at all? What happens when you set a break point?

Other then testing the length, you can also check to see if the textbox is equal to String.Empty. Both ways do the same thing.

I had problems with custom validation myself. I turn off CausesValidation for all buttons. Then when the validation button was clicked, it called Page.Validate() and then checked if the Page.IsValid is true. However, I never could get the CustomValidator to trigger. So what I did was manually triggered each custom validator, as so:

customvalidator1.Validate()

and checked if:

customvalidator1.IsValid = True

I don't know if this is the problem you are having, but I hope this helps.

Ok, here's the code:

In the page, I declare the Validator:
<asp:customvalidator id="CustomValidator1" style="Z-INDEX: 174; LEFT: 208px; POSITION: absolute; TOP: 736px" runat="server" ErrorMessage="Inquiry Duration must be greater than zero" OnServerValidate="CustomValidator1_ServerValidate" ControlToValidate="txtHourTenths"></asp:customvalidator>

In the codebehind, I have this code:
Sub CustomValidator1_ServerValidate(ByVal source As System.Object, ByVal args As System.Web.UI.WebControls.ServerValidateEventArgs) Handles CustomValidator1.ServerValidate
        If txtHour.Text.Length > 0 And txtHourTenths.Text.Length > 0 Then
            If IsNumeric(txtHour.Text) And IsNumeric(txtHourTenths.Text) Then
                If (CInt(txtHour.Text) + CInt(txtHourTenths.Text)) = 0 Then
                    CustomValidator1.IsValid = False
                End If
            End If
        End If
    End Sub

Then finally on submit of the page via a button, I have this in the codebehind:
Private Sub btnSubmit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSubmit.Click
        'check for contact info
        lblNoContact.Visible = False
        If txtAddress1.Text = "" And txtCity.Text = "" And txtZip.Text = "" And txtPhone.Text = "" And txtEmail.Text = "" Then
            lblNoContact.Visible = True
        Else
            If Page.IsValid Then
                Dim obj As New clsMyObject
                obj.Address1 = txtAddress1.Text
                obj.Address2 = txtAddress2.Text
                .
                .
                .
                obj.UserID = Session("UserID")
                Session("ConfirmText") = "Inquiry Added"
                obj.Add()
                Response.Redirect("DEconfirm.aspx")
            End If
        End If
    End Sub

That's it; again, I have a suspicion it's something basic that I'm missing. Hope this helps!

Brian, I will try the String.Empty suggestion after this posting - thank you.

Can you post the rest of the ASPX page as well? Makes it easier to replay your scenario.....
Or link to it somewhere online if it is very long.....
