asp.net gridview分页：第一页下一页 1 2 3 4 上一页最末页

效果图：

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();

  }
