Hi,

I have two accordion panes on a page and one of them includes a
DropdownList. I want to fill that DropdownList on page load but null
reference error occurs if the AccordionPane on which the DropdownList
exists is collapsed .Well but how can I fill my
little poor DropdownList with some data?

Thanks in advance.

Hi,

If you familier with Jquery you can use my code for filling dropdown list

from browser side when page loads in web browser.

HTML

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
    <script src="Scripts/jquery-1.4.1-vsdoc.js" type="text/javascript"></script>
    <script src="Scripts/jquery-1.4.1.js" type="text/javascript"></script>
    <script language ="javascript" >
        function f1() {
            $("#DropDownList1").html("<option value='fdgfdg'>gfdg</option><option value='dfgg'>gfdg");

        }
    </script>
</head>
<body onload ="f1()">
    <form id="form1" runat="server">
    <div>
       
        <asp:dropdownlist id="DropDownList1" runat="server" xmlns:asp="#unknown">
      
        </asp:dropdownlist>
     
    </div>

Solution 2

Could you please try accessing the DropDownList by using FindControl method of the Accordion/Accordion Pane.
