Problem with display PrintWidget and Others in TooltipDialog!

[HuyNguyen_Quoc]

Hi everybody,

I'm trying to display PrintWidget and Others in TooltipDialog but cannot success. Here is my sample code:

var btn_printer = new dijit.form.DropDownButton({
      dropDownPosition: ['after-centered'], 
      showLabel:false, 
      iconClass:'icon-measure'
     });
     var btn_printer_dialog = new dijit.TooltipDialog({
      content: '<div id="printPane"></div>'
     });
     btn_printer.set('dropDown',  btn_printer_dialog);

var printer = new esri.dijit.Print({
         map: map,
         url: "http://mydomain/arcgis/rest/PrintingTools/GPServer/Export%20Web%20Map%20Task",
  templates: [{
  label: "Map Layout",
  format: "PDF",
  layout: "MAP_ONLY",
  exportOptions: {
  width: dojo.position(dojo.byId("map")).w,
  height: dojo.position(dojo.byId("map")).h,
  dpi: 96
  }
  }]
     }, dojo.byId("printPane"));
  printer.startup();

Please help me to fix it. Thank you.
