Drop down list filter web part in Sharepoint is not getting exported

I would like to implement filtering on my sharepoint list. My list is having title and description columns and I would like to poulate the ASP.NET dropdown list control with titles and when I select the title I would like to show the description. I have followed the link h开发者_运维技巧ttp://msdn.microsoft.com/en-us/library/cc300163(office.12).aspx to implement this.

I have created a blank aspx page in Sharepoint Designer and followed the same steps. everything works fine but when I export the webpart, only description part is getting exported. I cannot see the drop down on the page (but when I preview it on the browser I can see both).

In your question you say that you are creating a aspx page and then exporting a webpart.

It could be that you are placing the drop down on one thing and exporting another.
