Aug 11, 2010

How exactly do I style this control?

I have tried this but it doesn't work.

<asp:FileUpload id="upload_tb" runat="server" />
width: 500px;

Also how can I style the browse button that comes with this control? If it is not possible are there other alternatives?


I checked the generated source and gives the control this id ctl00_main_content_upload_tb

I changed the CSS to
