这篇文章主要介绍了asp.net gridview分页：第一页 下一页 1 2 3 4 上一页 最末页，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,需要的朋友可以参考下
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;

document.getElementById("NUM").value = currentRowId;
}
</script>
