功能简介：可使用上下键选中行，选中后点击修改，textbox获得gridview中的代码的数据。对你有帮助的话，请记得要点击“好文要顶”哦！！！不懂的，请留言。废话不多说了，贴码如下：
<head runat="server"> <title>GridView分頁</title> <script type="text/javascript"> var currentRowId = 0; var styleName = ""; function SelectRow(ev, strGvName) { var e = window.event || ev; var keyCode = -1; if (e.which == null) keyCode = e.keyCode; // IE else if (e.which > 0) keyCode = e.which; // All others if (keyCode == 40) MarkRow(currentRowId + 1, strGvName); if (keyCode == 38) { MarkRow(currentRowId - 1, strGvName); } document.getElementById("NUM").value = currentRowId; } function MarkRow(rowId, strGvName) { var Grid = document.getElementById(strGvName); var rowCount = Grid.rows.length; if (document.getElementById(strGvName + rowId) == null) return; if (rowId == rowCount) { return; } if (document.getElementById(strGvName + currentRowId) != null) document.getElementById(strGvName + currentRowId).style.backgroundColor = styleName; currentRowId = rowId; styleName = document.getElementById(strGvName + rowId).style.backgroundColor; document.getElementById(strGvName + rowId).style.backgroundColor = 'red'; var obj = document.getElementById(strGvName); obj.rows[rowId].cells[0].focus(); document.getElementById("NUM").value = currentRowId; } </script> <style type="text/css"> .hidden { display: none; } </style> </head>
