Webpart visible depending on querystring

Hi,

I would like to know if it is possible to hide/show a WebPart depending on the querystring of the page. I have 2 pages with the same name, one for the list, one for the detail, so I thought about putting them together. However, I don't know if it's possible to do that in Portal Engine.

For example:

"http://site.com/myPage.aspx" shows Webpart1 and Webpart2 (list)
"http://site.com/myPage.aspx?id=1" shows Webpart 3 (detail)
"http://site.com/myPage.aspx?id=invalidID" show Webpart1 and Webpart2 (list) + Webpart4 (error message)

Is it possible? I can't seems to find how to do that.

Hello.

Regrettably, you can´t use query macro in web part properties (http://devnet.kentico.com/docs/devguide/appendix_a___macro_expressions.htm), therefore the easiest way would be to create and call custom macro within "Visible " property of given web part. Within this macro´s code, you can get query string parameter´s value (CMS.GlobalHelper.UrlHelper.GetUrlParameter method) and return true / false value according to it.

I've started working on that but I have a question. In a custom macro, all I can return is a string, so how to return a bool for a true/false value?

Web parts can handle it and will show / hide themselves according to this (even) string value. Best Regards, Radek Macalik
