ItemCommand only raised in IE

[golddog]

Not exactly accurate, but telerik won't let me edit the title.

The grid is a list of documents the user has stored.  To view a stored document, I created the view link; within the ItemCommand event handler I create a file and stream it back to the user as shown below.  However, the javascript to open a window to facilitate the streaming never gets invoked (except in IE browsers).

This is in a user control, although I don't think that's important.  Here's the mark-up:

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">

        }

        mediaList.get_ViewDocumentModalUrl = function mediaList_getViewDocumentModalUrl(mimeType) {
            var url = '<%= Page.ResolveClientUrl("~/MediaLibrary/Modals/ViewDocument.aspx") %>' + '?type=' + mimeType;
            return url;
        }

                }
            }

                //check for empty string or invalid extension
                if (inputs[i].value != "" && upload.isExtensionValid(inputs[i].value)) {

And the ItemCreated event handler, where I set up the "View" link.

protected void grdDocumentLibrary_ItemCreated(object sender, GridItemEventArgs e)
{
    if (e.Item is GridDataItem)
    {

        LinkButton btn = (LinkButton)((GridDataItem)e.Item)["ViewColumn"].FindControl("lnkView");
        Page page = HttpContext.Current.CurrentHandler as Page;
        Telerik.Web.UI.RadAjaxManager ajaxMgr = Telerik.Web.UI.RadAjaxManager.GetCurrent(page);
        if (ajaxMgr != null)
        {
            ajaxMgr.AjaxSettings.AddAjaxSetting(btn, grdDocumentLibrary, loadingPanel);
        }
    }
}

And here's where I handle the ItemCommand:

protected void grdDocumentLibrary_ItemCommand(object sender, GridCommandEventArgs e)
 {
     if (e.CommandName == RadGrid.InitInsertCommandName)
     {
         e.Canceled = true;
         e.Item.OwnerTableView.InsertItem(new PartnerDocument());
     }
     else if (e.CommandName.Equals("View"))
     {
         BernardClientContext bcc = BuildClientContext();
         DocumentService ds = new DocumentService(new DocumentRepository(bcc));
         Document doc = ds.GetById(new Guid((string)e.CommandArgument));

         string filePath = System.Configuration.ConfigurationManager.AppSettings["GeneratedDocuments"];
         if (HttpContext.Current != null)
         {
             filePath = HttpContext.Current.Server.MapPath(filePath);
         }

         string fileName = null;
         Mutex fileMutex = null;
         try
         {
             while (true)
             {
                 fileName = doc.FileName + "_" + System.DateTime.Now.ToString("ddMMyyyyhhmmss") + doc.DocumentType.Name;

                 bool created;
                 fileMutex = new Mutex(true, fileName.Replace("\\", "_"), out created);
                 if (fileMutex != null && created)
                 {
                     if (!System.IO.File.Exists(filePath + fileName))
                         break;

                     fileMutex.ReleaseMutex();
                 }

                 System.Threading.Thread.Sleep(1000);
             }

             File.WriteAllBytes(filePath + fileName, doc.DocumentContent.Content);

             Page page = HttpContext.Current.CurrentHandler as Page;
             Telerik.Web.UI.RadAjaxManager ajaxMgr = Telerik.Web.UI.RadAjaxManager.GetCurrent(page);
             Session["documentToStream"] = filePath + fileName;
             if (ajaxMgr != null)
             {
                 ajaxMgr.ResponseScripts.Add(String.Format("mediaList.openViewWindow('{0}'); return false;", doc.MimeType));
             }
             else
             {
                 page.ClientScript.RegisterStartupScript(page.GetType(), "documentStream", String.Format("mediaList.openViewWindow('{0}'); return false;", doc.MimeType), true);
             }

         }
         finally
         {
             if (fileMutex != null)
                 fileMutex.ReleaseMutex();
         }
     }
 }

One of my co-workers found that splitting my javascript between RadCodeBlack and RadScriptBlock was the culprit.  Clearly, I need to read up on those.
