Custom Validator not firing 2

[guitardave78]

Hi guys, I am trying to set up a custom validator but it does not seem to work. My required field validators all work but not this.
For the sake of testing the validator is being set to just return false

here is my code aspx

              <input type="text" id="ad_year" name="ad_year" runat="server" />
			  	<asp:CustomValidator id="CustomValidator1"
				ControlToValidate="ad_year"
				OnServerValidate="ServerValidation"
				ErrorMessage="Not a number!"
				runat="server"/>

here is the c#

    void ServerValidation (object source, ServerValidateEventArgs args)
      {           
            args.IsValid = false;
      }

any ideas why this does not work?

It's because validators are generally designed to work client-side - try inserting your validation sub right in the HTML view. Sorry my example is VB, it should be easy to change if necessary.

<script language="vb" runat="server">
Sub validateme(sender as Object, args as ServerValidateEventArgs)
   args.IsValid = False
End Sub
</script>

<asp:CustomValidator id="CustomValidator1" style="Z-INDEX:101; LEFT: 424px; POSITION: absolute; TOP: 240px" runat="server" ErrorMessage="error!"  ControlToValidate="TextBox1" OnServerValidate="validateme"></asp:CustomValidator>

dace - won't that still run server-side as you have runat=server in your first line?

That just makes it such that there's a reference to it in the code-behind. It'll still run clientside code.

 

[ca8msm]

But you only call this function on the server validate e.g.

OnServerValidate="validateme"

Surely if you want client side validation you have have to use a javascript function on the ClientValidationFunction?

Oh and by the way guitardave - there's a nice sample at:

Again, it's in VB.NET but...

ca8msm - yes it will still run on the server, but I've always found that the one way seems to work and the other doesn't All validator controls validate serverside, even the premade ones. The clientside javascript just makes it seamless (straight from MSDN).

you could also write a javascript function like the following:

<script language="JavaScript">
<!--
  function ValidateMe(sender, args)
  {
    args.IsValid = false;
  }
// -->
</script>

and insert it into the html of the page, then call this. This would make it run a little nicer on uplevel browsers.
