关于Repeater中嵌套GridView以及GridView中checkbox的全选功能的实例
具体的思路为：首先生成一个Repeater，然后根据在Repeater绑定的ID生成GridView，具体实现界面及代码如下所示：
前台代码：
',this.checked);" type="checkbox" />
')"> <%#DataBinder.Eval(Container.DataItem, "GroupName")%>
" class="TableLine2" width="100%">
AutoGenerateColumns="False" Width="100%" DataKeyNames="AddressId" OnRowDataBound="GridView1_RowDataBound" OnRowDeleting="GridView1_RowDeleting" OnRowEditing="GridView1_RowEditing" OnRowUpdating="GridView1_RowUpdating" OnRowCancelingEdit="GridView1_RowCancelingEdit" HorizontalAlign="Center">
前台代码中，加红色的AutoGenerateColumns="False" ，只有设置为False时，GridView的更新操作才能被执行，需要注意。
后台代码：
#region 数据绑定
//绑定Repeater
protected void LoadDataRep()
{
pnlmain.Visible = true;
DBConnect db = new DBConnect();
DataTable dt = db.ExecuteDataTable("select * from Address_Group where GroupId in(select GroupId from [Address] group by(GroupId)) and GroupId in(select GroupId from Address_Group where UserId='" + Utilities.CookieUtil.UserID + "')");//
if (dt == null)
{
pnlmain.Visible = false;
litMessage.Text = "没有定义记录
";
}
dt.Columns.Add("GroupNo", typeof(string));
for (int i = 0; i < dt.Rows.Count; i++)
{
dt.Rows[i]["GroupNo"] = i.ToString("00");
}
Repeater1.DataSource = dt;
Repeater1.DataBind();
}
//绑定GridView
protected void BindData(GridView gv, string GroupId)
{
pnlmain.Visible = true;
DBConnect db = new DBConnect();
DataTable dtnow = db.ExecuteDataTable("select [GroupId],[AddressId],[Name],[DeptName],[Mobile],[Ministration] from Address where GroupId=" + GroupId);
gv.DataSource = dtnow;
gv.DataBind();
db.Close();
}
//Repeater绑定数据时，将GroupId绑定到Label上，并根据GroupId绑定对应的gridview
protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
Label lblid = null;

隐藏/显示的JS代码
function clickMenu(ID)
{
targetelement=document.all(ID);
if (targetelement.style.display=="none")
targetelement.style.display='';
else
targetelement.style.display="none";
}全选的JS代码：
function grcheckalll(name,obj)
{
var gridname="Repeater1_ctl"+name+"_GridView1";
var rowcount=document.getElementById(gridname).rows.length;
for(var a=2;a<=rowcount+1;a++)
{
if(a>=10)
{var ckid=gridname+"_ctl&_chkIsCheck";
}
else
{var ckid=gridname+"_ctl0&_chkIsCheck";}
var aa=ckid.replace("&",a);
var bb=document.getElementById(aa);
if(bb!=null)
{
bb.checked=obj;
}
}
} 由于GridView中的控件的ID名字是自动生成的，但是也是有规律的，只需要在浏览器中查看下生成的页面源文件中的name，然后找出规律就可以了。
整体功能也是比较简单，不过对于初次接触这些的还有一些参考的价值的。
