jQuery.fn.highlight = function (pat) {

    function innerHighlight(node, pat) {

        var skip = 0;

        if (node.nodeType == 3) {

            var pos = node.data.toUpperCase().indexOf(pat);

            if (pos >= 0) {

                var spannode = document.createElement('span');

                spannode.className = 'highlight';

                var middlebit = node.splitText(pos);

                var endbit = middlebit.splitText(pat.length);

                var middleclone = middlebit.cloneNode(true);

                spannode.appendChild(middleclone);

                middlebit.parentNode.replaceChild(spannode, middlebit);

                skip = 1;

            }

        }

        else if (node.nodeType == 1 && node.childNodes && !/(script|style)/i.test(node.tagName)) {

            for (var i = 0; i < node.childNodes.length; ++i) {

                i += innerHighlight(node.childNodes[i], pat);

            }

        }

        return skip;

    }

    return this.each(function () {

        innerHighlight(this, pat.toUpperCase());

    });

};

jQuery.fn.removeHighlight = function () {

    return this.find("span.highlight").each(function () {

        this.parentNode.firstChild.nodeName;

        with (this.parentNode) {

            replaceChild(this.firstChild, this);

            normalize();

        }

    }).end();

};

Then Add this Script in Head Tag and add TextBox ID in third line..

Dnt delete ClientID, write down it with ur textboxid..

e.g : var  value = document.getElementById('<%#urtxtboxid.ClientID%>').value;

  <script type='text/javascript'>

        function mark() {

            var value = document.getElementById('<%#TextBox7.ClientID%>').value;

            $('#GridView1').highlight(value);

        }

    </script>

Then Call Mark() Method from through javascript as ur wish... like 'onmouseover=mark();'  OR onblur="mark();" etc......
