Simple custom validation trouble...

[song2siren]

Hello

I just need to create a custom validator to check whether a control contains a value and, if it doesn't, change the style of div tag.

I tried this:

Sub surnameCheck_ServerValidate(sender as Object, e as ServerValidateEventArgs)
Dim strValue As String = e.Value
If not strValue is nothing then
e.IsValid = True
Else
e.IsValid = False
lblSurnameRow.Text = "<div class='row error'>"
End If
End Sub

With my controls like this:

<asp:Label ID="lblSurnameRow" runat="server"><div class="row"></asp:Label>
<span class="formElement"><asp:TextBox ID="frmSurname" onfocus="pviiW3Cbg(this,'#F4DFA9')" onblur="pviiW3Cbg(this,'#E5EFFF')" runat="server" /></span>
<asp:CustomValidator ControlToValidate="frmSurname" Display="Dynamic" runat="server" OnServerValidate="surnameCheck_ServerValidate" />

However, the form is submitted regardless of a value in frmSurname.

Hopefully, I'm missing something really simple, but any suggestions would be much appreciated.

Thanks

what you do there is make a server validation. you need to make a client validation too. so you should add a ASP required field validator to your form, bind it to your control and add a custom client script to add for it.
