I am trying to add an accordion control to one of my pages.
Following is the code:
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server">

<cc1:Accordion ID="Accordion1" runat="server">
<panes>
<cc1:AccordionPane ID="AccordionPane1" runat="server">



</form>

but I am getting this error:
An unhandled exeception has occurred.
Collection was modified; enumeration operation may not execute

Searched on this error but no results seemed to pertain to my problem. Can someone tell me what I have done wrong?

Thanks

推荐答案

您似乎丢失了< ;％@注册Assembly ="AjaxControlToolkit"命名空间="AjaxControlToolkit" TagPrefix ="ajaxToolkit">.

另外，请确保已在项目中包含AjaxControlToolkit的DLL.您也可以签出

希望这对您有帮助...:)

You seem to be missing <%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="ajaxToolkit">.

Also, make sure you''ve included the AjaxControlToolkit''s DLL in your project. You can also check out

为手风琴标题和内容添加CSS类.

然后错误就会消失.....

Add CSS class for accordion header and content.

then error will dissapear.....

确保已包含< cc1:Accordion ID ="Accordion1" runat ="server的SelectedIndex =" 0属性>
并且在Accordian标签中，我们应该至少实现了3个属性以及id，runat属性

希望这对您有帮助...

make sure you''ve included the SelectedIndex="0" property of <cc1:Accordion ID="Accordion1" runat="server">
and in accordian tag we should have implemented at least 3 properties along with id , runat properties

Hope this may help u...
