        function ValidateText(i) {
            if (i.value.length > 0) {
                i.value = i.value.replace(/[^'d]+/g, '');
                var yourBoundColumnValue = i.parentNode.previousSibling.childNodes[0].nodeValue;
                var total = 0;            
                var tot = document.getElementById('<%=lblBalQty.clientId %>').innerHTML
                alert(Number(tot));
                tot.innerHTML = i.value;
                tot.innerHTML = yourBoundColumnValue - i.value;
            }
        }

 function calculate(object) {
        var _name = object.id;
        var New = _name.split('_');
        if (object.value.length > 0) {
            object.value = object.value.replace(/[^'d]+/g, '');
        }
        var _ans = 0;
        var _num1 = document.getElementById(New[0] + "_" + New[1]+ "_" + New[2] + "_" + New[3] + "_txtSupQty").value;
        if (_num1 == 'NaN' || _num1=='') {
            _num1 = 0;
        }
        var yourBoundColumnValue = object.parentNode.previousSibling.childNodes[0].nodeValue;
        if (parseInt(_num1) >= 0 && _num1 != 'NaN' ) {
             _ans = parseInt(yourBoundColumnValue)-parseInt(_num1);
         }
         document.getElementById(New[0] + "_" + New[1] + "_" + New[2] + "_" + New[3] + "_lblBalQty").innerHTML = parseFloat(_ans);                
    }                                

<asp:TemplateField HeaderText="">
<ItemTemplate>
<asp:Button ID="btn_delete_row" runat="server" OnClientClick="qrowdetele(this)" Text="Delete Row" class="btn" />
                                             </ItemTemplate>
                    </asp:TemplateField>

在gridview内部传递objcet this is javascript函数，然后javascript函数。就是这个

function qrowdetele(rowobject)
        {
            var row = rowobject.parentNode.parentNode;
            var rowIndex = row.rowIndex - 1;
           //getting data
            var lablevalue= document.getElementById("ContentPlaceHolder1_grd_view_lbl_for_update_status_"+rowIndex)[0].value;
            alert("RowIndex: " + rowIndex + "lable value:" +lablevalue);
//setting data 
        document.getElementById("ContentPlaceHolder1_grd_view_lbl_for_update_status_" + rowIndex)[0].value = "MarkedForDeletion";

        }

内容占位符1_grd_view_lbl_for_update_status_

ContentPlaceHolder1:gridview所在的内容占位符的id（这里是主控子页面概念中的子页面，因此在正常页面中不需要）

grd_view：是gridview 的id

lbl_for_update_status：标签的id
