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：

<asp:Panel ID="pnlmain" runat="server">
        <asp:Repeater ID="Repeater1" runat="server"  OnItemDataBound="Repeater1_ItemDataBound">
        <ItemTemplate>
        <table class="small" width="100%">
        <tr width="100%" class="TableHeader" align="left" >
        <td width="20px">
<input id="Checkbox1" name='<%#DataBinder.Eval(Container.DataItem, "GroupId")%>' onClick="grcheckalll('<%#DataBinder.Eval(Container.DataItem, "GroupNo")%>',this.checked);" type="checkbox" /><!--Repeater中的CheckBox，全选操作-->
          </td>
<td width="780px" title="点击隐藏/显示" onclick="clickMenu('tr+<%#DataBinder.Eval(Container.DataItem, "GroupId")%>')"> <%#DataBinder.Eval(Container.DataItem, "GroupName")%><!--此处为设置某个点击某组标题可以隐藏或显示-->
        </td>
        </tr>
        <tr  id="tr+<%#DataBinder.Eval(Container.DataItem, "GroupId")%>" class="TableLine2" width="100%"><td align="center" valign="middle" nowrap colspan="2">
        <asp:Label ID="lbl_Id" Visible=false Text='<%# DataBinder.Eval(Container.DataItem,"GroupId").ToString() %>' Runat=server />
        <asp:GridView ID="GridView1" CssClass="small" runat="server" BorderStyle="Inset" AutoGenerateColumns="False" Width="100%" DataKeyNames="AddressId" OnRowDataBound="GridView1_RowDataBound" OnRowDeleting="GridView1_RowDeleting" OnRowEditing="GridView1_RowEditing" OnRowUpdating="GridView1_RowUpdating" OnRowCancelingEdit="GridView1_RowCancelingEdit" HorizontalAlign="Center">
            <Columns >
                <asp:TemplateField HeaderText="选择">
                    <ItemTemplate>
                        <asp:CheckBox ID="chkIsCheck" runat="server" />

                    <ControlStyle Width="120px" />

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。

全选、隐藏/显示的JS代码：

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。
