Do you have an actual question? BTW: only add code that is directly related to the problem you require help with: no one has the time to wade through everything!

Sergey Alexandrovich Kryukov 6-Jun-12 14:51pm

Right. I always insist that in complex problems inquirers should create a code complete but short sample focused on a specific problem, specially for the CodeProject question.
First, it helps to isolate problem, which itself can lead to its resolution without asking CodeProject. And finally, it makes the question answerable.

Hi,

I don't think you can access the radio collection named 'se' in the way you're trying to. Replace this code:

JavaScript

function jksitesearch(curobj)
     {
         for (i = 0; i < document.jksearch.se.length;i++ )
        { //loop through radio to see which is checked
            if (document.jksearch.se[i].checked == true)
                switchaction(document.jksearch.se[i],i)
        }
        document.getElementById("hiddenquery").value = "site:" + domainroot + " " + curobj.qfront.value
    }

With:

C#

function jksitesearch(curobj)
     {
         var se = document.getElementsByName('se');
         for (i = 0; i < se.length;i++ )
        { //loop through radio to see which is checked
            if (se[i].checked == true)
                switchaction(se[i],i)
        }
        document.getElementById("hiddenquery").value = "site:" + domainroot + " " + curobj.qfront.value
    }
