adding variable to HTTP query string from code

[dstepans]

Hello,

is it possible to add a variable to the HTTP query string?
For examle the requested URL was

http://www.somewebsite.com/page.aspx,

but in the page.aspx I have a control that queries the request.querystring("ID"), so what I need is to somehow in the code add an ID variable and set it to lets say 5, so request.querystring("ID") would return 5.

Thanks,
Denis

Hi!
You could add the desired querystring from the refferer page. I.e. on page1.aspx you can have a link like this:

<asp:HyperLink id="lnk" runat="server" NavigateUrl="[URL unfurl="true"]http://www.something.com?ID=5"/>[/URL]

or a button that has its onClick event like this:

Response.Redirect("[URL unfurl="true"]http://www.something.com?ID=5")[/URL]

I hope this is what you wanted!

Hi,
thanks for your response.
Not what I wanted though.

What I would like to do is to exactly the opposite, I would like to avoid placing variable in the referred URLs. The url will look like

http://www.somewebsite.com/page1.aspx

or

http://www.somewebsite.com/page5.aspx

but in page5.aspx.vb file I need to somehow add Cat=5 to the querry string.

Thanks for any help guys.

I think you're referring to data persistence. There are quite a few methods. You could look into hidden form elements, cookies, session variables, temporary database tables, XML/Text Documents, Page properties ... You can then retreive this data and then append it to the URL as a querystring variable.

HTH,
