Hi Tony, I add an editrules option to validate URLs that I thought was worth suggesting.  I think someone who is a lot better at REGEX than I am could take this much further, but I'll post the basic expression that I've settled on for now.

I did this for 3.5A3 - in grid.common.js, add the following in function checkValues

// begin: url validation
        if(edtrul.url === true) {
            if( !(rqfield === false && isEmpty(val)) ) {
                var filter = /^(((https?)|(ftp)):\\/\\/([\\-\\w]+\\.)+\\w{2,3}(\\/[%\\-\\w]+(\\.\\w{2,})?)*(([\\w\\-\\.\\?\\\\/+@&#;`~=%!]*)(\\.\\w{2,})?)*\\/?)/i;
                if(!filter.test(val)) {return [false,g.p.colNames[valref]+": "+jQuery.jgrid.edit.msg.url,""];}
            }
        }
// end: url validation

and in grid.locale-en.js, in the "edit" block, I added

url: "is not a valid URL...prefix required ('http://' or 'https://')",

and of course, in the colModel,

editrules:{url:true}

If shear length is any indication of a REGEX's effectiveness, the one at the end of this page looks pretty good (also posted below):  http://geekswithblogs.net/casualjim/archive/2005/12/01/61722.aspx

^(?#Protocol)(?:(?:ht|f)tp(?:s?)\\:\\/\\/|~/|/)?(?#Username:Password)(?:\\w+:\\w+@)?(?#Subdomains)(?:(?:[-\\w]+\\.)+(?#TopLevel Domains)(?:com|org|net|gov|mil|biz|info|mobi|name|aero|jobs|museum|travel|[a-z]{2}))(?#Port)(?::[\\d]{1,5})?(?#Directories)(?:(?:(?:/(?:[-\\w~!$+|.,=]|%[a-f\\d]{2})+)+|/)+|\\?|#)?(?#Query)(?:(?:\\?(?:[-\\w~!$+|.,*:]|%[a-f\\d{2}])+=(?:[-\\w~!$+|.,*:=]|%[a-f\\d]{2})*)(?:&(?:[-\\w~!$+|.,*:]|%[a-f\\d{2}])+=(?:[-\\w~!$+|.,*:=]|%[a-f\\d]{2})*)*)*(?#Anchor)(?:#(?:[-\\w~!$+|.,*:=]|%[a-f\\d]{2})*)?$

but it threw an error and I couldn't even begin to debug it, so went with the simple example above.

Thanks!

Adam
