<script type="text/javascript">        function Check(parentChk, pattern) {
            var elements = document.getElementsByTagName("INPUT");
            for (i = 0; i < elements.length; i++) {
                if (parentChk.checked == true) {
                    if (IsCheckBox(elements[i]) && IsMatch(elements[i].id, pattern)) {
                        elements[i].checked = true;
                    }
                }
                else {
                    if (IsCheckBox(elements[i]) && IsMatch(elements[i].id, pattern)) {
                        elements[i].checked = false;
                    }
                }
            }
        }
        function IsMatch(id, pattern) {
            var regularExpression = new RegExp(pattern);
            return id.match(regularExpression);
        }
        function IsCheckBox(chk) {
            return (chk.type == 'checkbox');
        }
           </script>
 <asp:TemplateField HeaderText="全选">
                                <HeaderTemplate>
                                    <asp:CheckBox ID="CheckBox1" runat="server" Text="全选" onclick="Check(this,'^DataGridView')" />
