HTML code

  function selectAll(obj)    {        var theTable  = obj.parentElement.parentElement.parentElement;        var i;        var j = obj.parentElement.cellIndex;                for(i=0;i<theTable.rows.length;i++)        {            var objCheckBox = theTable.rows[i].cells[j].firstChild;            if(objCheckBox.checked!=null)objCheckBox.checked = obj.checked;        }    }<ItemTemplate> <asp:CheckBox ID="chbCheck" runat="server" /></ItemTemplate><HeaderTemplate>　<asp:CheckBox ID="chbCheckHeader"  onclick="selectAll(this);" AutoPostBack="false" runat="server" /></HeaderTemplate>

你可以分在前台和后台。
于后台的在此先放一下，一下如何在前台操作.
效果可以考很多网站。比如迅雷的首,分作了"全(全部中)"和"全消(全部不)"按.
段代的可以考一下:
JScript code
function checkAll(checkedValue){    for(var i=0;i<document.getElementsByName("chk").length;i++)    {        var thisCheckBox=document.getElementsByName("chk")[i];        thisCheckBox.checked=checkedValue;    }}
