ScriptManager Conflicting with CustomValidator Client Validation Function
<p>For the clarity's sake, consider the following form that is based on a master page file.</p>

<p><strong>Form</strong>:</p>

<pre><code>&lt;%@ Page Language="C#" AutoEventWireup="true" CodeFile="Test.aspx.cs" Inherits="Secured_Test" MasterPageFile="~/MasterPages/Test_SiteMaster.master" %&gt;

&lt;asp:Content runat="server" ContentPlaceHolderID="MainPageContent"&gt;

  &lt;script type="text/javascript"&gt;
    function ClientValidate(source, args) 
    {
      alert('foo');
    }
  &lt;/script&gt;

  &lt;asp:DropDownList runat="server" id="ddl"&gt;
    &lt;asp:ListItem Text="value 1" Value="1" /&gt;
    &lt;asp:ListItem Text="value 2" Value="2" /&gt;
  &lt;/asp:DropDownList&gt;

  &lt;asp:CustomValidator ID="CustomValidator1" runat="server" Text="Error!" ClientValidationFunction="ClientValidate" /&gt;

  &lt;asp:Button ID="Button1" runat="server" Text="Submit" CausesValidation="true" /&gt;

&lt;/asp:Content&gt;
</code></pre>

<p><strong>My master page contains the following code:</strong></p>

<pre><code>&lt;asp:ScriptManager ID="ToolkitScriptManager1" runat="server"&gt;
  &lt;Scripts&gt;
    &lt;asp:ScriptReference Name="jquery" /&gt;
  &lt;/Scripts&gt;
&lt;/asp:ScriptManager&gt;
</code></pre>

<p><strong>Question / Issue:</strong></p>

<p>As is, <code>ClientValidate</code> function never fires. If I remove the ScriptManager call in my MasterPageFile, the code works as expected (<code>ClientValidate</code> is called and and an alert is issued when the button is clicked). Thank you in advance!</p>
