关于VS2005中GridView的自定义分页，单选、多选、排序、自增列的简单应用

关于VS2005中GridView的自定义分页，单选、多选、排序、自增列的简单应用。
多选时，只有全部选中时“多选”才选中。

简单示例，代码如下，
fenpage.aspx的代码：

<% @PageLanguage="C#"AutoEventWireup="true"CodeFile="fenpage.aspx.cs"Inherits="gridview_fenpage" %>

<! DOCTYPEhtmlPUBLIC"-//W3C//DTDXHTML1.0Transitional//EN""http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd" >
< html xmlns ="http://www.w3.org/1999/xhtml" >
< head runat ="server" >
< title ></ title >

< script language ="javascript" type ="text/javascript" >
//判断多选是否与选中项（没有选中的返回false）
functionslcNo_click()
{
if(document.form1.checkboxname.length)
{
for(vari=0;i<document.form1.checkboxname.length;i++)
{
if(document.form1.checkboxname[i].checked)
{
returntrue;
}
}
}
else
{
if(document.form1.checkboxname.checked)
{
returntrue;
}
}
alert("请选择后再操作！");
returnfalse;
}

//鼠标经过改变行的颜色
if(!objbeforeItem)
{
varobjbeforeItem=null;
varobjbeforeItembackgroundColor=null;
}
functionItemOver(obj)
{
if(objbeforeItem)
{
objbeforeItem.style.backgroundColor=objbeforeItembackgroundColor;
}
objbeforeItembackgroundColor=obj.style.backgroundColor;
objbeforeItem=obj;
obj.style.backgroundColor="#B9D1F3";
}
//

//多选的全选与取消
functioncheckJs(boolvalue)
{
if(document.all.checkboxname.length>1)
{
for(vari=0;i<document.all.checkboxname.length;i++)
{
document.all.checkboxname[i].checked=boolvalue;
}
}
else
document.all.checkboxname.checked=boolvalue;
}
//

//只有全部选中时“全选”选中
functionSingleCheckJs()
{
varflag1=false;
varflag2=false;

if(document.form1.checkboxname.length)
{
for(vari=0;i<document.form1.checkboxname.length;i++)
{
if(document.form1.checkboxname[i].checked)
flag1=true;
else
flag2=true;
}
}
else
{
if(document.form1.checkboxname.checked)
flag1=true;
else
flag2=true;
}

if(flag1==true&&flag2==false)
document.getElementById("chk").checked=true;
else
document.getElementById("chk").checked=false;
}
