[Solved] Expand/Collapse PanelBar from JQuery Script

[John]

I'm trying to dynamically expand/collpase Telerik Panel bar from Jquery (onload)
Using  jquery-1.7.1.min.js script file reference  

I'm getting error when  I try to use the following code (reason is .element is undefined), Could you please assist me?

function expandPanel(){
      var panelBar  = $("#PanelBar").data("tPanelBar");
      var item = ("> li",panelBar.element)[0];
      panelBar.expand(item);
}

$(document).ready(function () {

expandPanel();
}

Hello Chris,

Your code looks completely valid. I suspect you are loading the jQuery mutiple times in your page and this causes the data of the PanelBar client object to be cleared.
Make sure you load only once the jQuery script or share your layout page code and current view code so we can take a look.
