Hey This Javascript work fine for me

//for serching gridview on keyup
        function Filter(Obj) {

            var grid = document.getElementById('cntPlcHolder_gvDisplay');
            var terms = Obj.value.toUpperCase();
            var cellNr = 0; //your grid cellindex like name
            var ele;
            for (var r = 1; r < grid.rows.length; r++) {
                ele = grid.rows[r].cells[cellNr].innerHTML.replace(/<[^>]+>/g, "");
                if (ele.toUpperCase().indexOf(terms) >= 0)
                    grid.rows[r].style.display = '';
                else grid.rows[r].style.display = 'none';
            }
        }

<asp:TextBox ID="TextBox1" runat="server">

<input type='text' önkeyup='Filter(this);' id="txtSearch" class="SmallTextBox" runat="server" />
