สอบถามวิธี Focus แถวใน Gridview เมื่อเรา กด Edit ครับ

//วาง div ครอบ ASP.NET GridView
//<div id="Hack">
//your GridView
$(function() {
var gv = document.getElementById('Hack'); //jQuery Selector $('#Hack');
if (gv != null) {
   var that = $(gv);
   var height = isNaN(window.innerHeight) ? window.clientHeight : window.innerHeight;
   gv.style.height = (height - 1500) + 'px';
   //คำนวณ
   // that.scrollTop(ก็ว่ากันไป); //ยกตัวอย่างเช่น GridView == จำนวนแถว x ความสูงของแต่ละแถว
}
});
//</div

        //jQuery Datatables 1.10.xxx
        $('.myDataTables tbody').on("dblclick", "tr", function () {
            var tables = $('.dataTable').DataTable(); // get all visible Datatables instances
            var oTable = tables.table($(this).parents('table')); //this == tr
            //เลบหอย//oTable.row('.selected').remove().draw(false);     
            var rowArray = oTable.row(this).data(); //Array data
            var rowArray2rowData = rowArray.join("¾"); //String data separated ¾
            var rowData2rowArray = rowArray2rowData.split("¾"); //Array data
            //var ref = $(this).find('td:eq(0)').text(); //$(this).find('td:first').text();
            if (rowArray2rowData) {
                showMessageBox(rowArray2rowData); //Define in WL_Std.js
            }
        });

// SEX CheckBox
var cb_selected = [];
$('.myDataTables tbody').on("change", "tr .checkboxes", function () {
    var id = $(this).parents('tr').attr('id');
    var index = $.inArray(id, cb_selected);
    if (index === -1) {
        cb_selected.push(id);
    }
    else {
        cb_selected.splice(index, 1);
    }
    var checked = $(this).is(":checked");
    if (checked) {
        $(this).attr("checked", true);
        $(this).parents('tr').addClass("active");//active selected
    }
    else {
        $(this).attr("checked", false);
        $(this).parents('tr').removeClass("active");//active selected
    }
});

// คลิ๊กแถว (row Click)
var selected = [];
$('.myDataTables tbody').on('click', 'tr', function () {
    var tables = $('.dataTable').DataTable(); // get all visible Datatables instances
    var oTable = tables.table($(this).parents('table')); //this == tr
    selected.length = 0; //Clear Array
    oTable.$('tr.selected').removeClass('selected');
    //Single row selected.
    selected.push(this.id);
    $(this).toggleClass('selected');
});
