There is no source available for the current location
<p>There is no source available for the current location.What does that mean and how do I fix the problem. Here is my <code>code-behind.cs</code>. I trying to create a checkbox that when checked or unchecked displays a label Updated for 1 second then fades out. Functionality is if the user checks or unchecks the checkbox the label is displayed then fades out, please see code I having trouble getting this functionality.</p>

<pre><code>protected void chkDefault_CheckedChanged(object sender, EventArgs e)
    {
        if (chkDefault.Checked == false)
        {
            lblAdmin.Visible = false;
            txtProfileName.Visible = true;
        }
        if (chkDefault.Checked == true)
        {
            lblAdmin.Visible = true;
            txtProfileName.Visible = false;
            txtProfileName.Text = "";
        }
        Update();
    }

    private void Update()
    {
        myLabel.Text = "Updated!";
        UpdatePanel1.Update();
    }
}
</code></pre>

<p>Here is the <code>HTML</code> that goes with it.</p>

<pre><code>&lt;script type="text/javascript"&gt;
    $(function() {
        setTimeout(function() {
            fadeText();
            }, 1500);

            function fadeText() {
                $("#&lt;%=myLabel.ClientID%&gt;").fadeOut("slow");
            }
        }); 
&lt;/script&gt;

&lt;asp:UpdatePanel ID="UpdatePanel1" runat="server"  UpdateMode="Conditional"&gt;
    &lt;ContentTemplate&gt;
        &lt;asp:CheckBox ID="chkDefault" runat="server" Text="Default" Checked="true" 
            width="150px" oncheckedchanged="chkDefault_CheckedChanged" 
            AutoPostBack="true"/&gt;
        &lt;asp:Label ID="myLabel" runat="server" CssClass="fadeLabel"&gt;&lt;/asp:Label&gt;
    &lt;/ContentTemplate&gt;
    &lt;/asp:UpdatePanel&gt;
    &lt;asp:UpdatePanelAnimationExtender ID="UpdatePanelAnimationExtender1" runat="server" 
    BehaviorID="animation" TargetControlID="UpdatePanel1"&gt;
        &lt;Animations&gt;
            &lt;OnUpdated&gt;
                &lt;Sequence&gt;
                    &lt;ScriptAction Script="fadeOut()"&gt;&lt;/ScriptAction&gt;
                &lt;/Sequence&gt;
            &lt;/OnUpdated&gt;
        &lt;/Animations&gt;
&lt;/asp:UpdatePanelAnimationExtender&gt;
</code></pre>
