Javascript variable not found
<p>i have the script on ASPX: </p>

<pre><code>&lt;dx:ASPxButton ID="ASPxButton_PrintLetrVoit" runat="server" Text="Impression lettre de voiture(décalage)" AutoPostBack="False"&gt;
      &lt;ClientSideEvents Click="function (s, e) { e.processOnServer = false; for (var i = 0; i &lt; Tourne.length; i++) {window.open('PrintLettreVoit.aspx?TourneId='+Tourne[i]);}}" /&gt;
&lt;/dx:ASPxButton&gt;
</code></pre>

<p>and in cs :</p>

<pre><code>public List&lt;string&gt; Tourne;

protected void Page_Load(object sender, EventArgs e)
{
      try
      {
          foreach (var oItem in oOrdre_BL.GetAllLettrVoit_Tourne())
          {
           Page.ClientScript.RegisterArrayDeclaration("Tourne", "'"+oItem+"'");
          }
      ......
</code></pre>

<p>unfortunately i got Error on javascript:
i got error:</p>

<pre><code>Horodatage : 06/09/2012 11:23:03
Erreur : ReferenceError: Tourne is not defined
Fichier Source : http://xxxxxxx/Code/BackEnd/FaExped_BackEnd_WebSite/Ordre.aspx
Ligne : 5146
</code></pre>

<p>any idea ?</p>

<p>Thanks you in advance</p>

<p>PS: when i see the source code that generated:</p>

<pre><code>&lt;script type="text/javascript"&gt;
//&lt;![CDATA[
var Tourne =  new Array('');
//]]&gt;
&lt;/script&gt;


&lt;script type="text/javascript"&gt;
//&lt;![CDATA[

WebForm_InitCallback();//]]&gt;
&lt;/script&gt;
&lt;/form&gt;


&lt;/body&gt;
&lt;/html&gt;
</code></pre>

<p>i have modified my code:</p>

<pre><code> &lt;dx:ASPxButton ID="ASPxButton_PrintLetrVoit" runat="server" Text="Impression lettre de voiture(décalage)" AutoPostBack="False"&gt;
                          &lt;ClientSideEvents Click="function (s, e) {   
                          if(typeof(Tourne) !== 'undefined' &amp;&amp; Tourne != null) 
                          {
                            e.processOnServer = false; 

                             for (var i = 0; i &lt; Tourne.length; i++) {window.open('PrintLettreVoit.aspx?TourneId='+Tourne[i]);}
                          }
                          else
                          {alert ('Tous est coches');}

                             }" /&gt;
                        &lt;/dx:ASPxButton&gt;
</code></pre>

<p>but still, it is not a good solution, because i don't know why Tourne is undefined?</p>
