Does anyone have a good example of how to use the UrlHelper Class to add to the query string when using a smart filter. I am trying to add in a form control that will accept a "From" date and a "To" date from the user and add a query string to a filter. I can get the filter to accept the values from the url when I type them in manually, but I don't understand how the UrlHelper is used to add these to the URL.

Any help would be appreciated.

Thanks
