CheckBox cb = (CheckBox)row.FindControl("chkBoxId");
chkBoxId is your check box id.

this is an example
try this

write Javascript function To store Productid (1|2|3|4) in this way

function Fn_JsOrders_GetCheckBoxList() {
            var jsVar_Orders_OrderId = "";
            var flag = false;

            // alert(document.aspnetForm.OrderId.length);
            var ctrls = document.getElementsByTagName("input");
            for (var i = 1; i < ctrls.length; i++) {
                if (ctrls[i].checked == true) {
                    //  alert(jsVar_Orders_OrderId);
                    jsVar_Orders_OrderId = jsVar_Orders_OrderId + ctrls[i].value + "|";
                }
            }
            if (jsVar_Orders_OrderId.length == 0) {
                alert("Please Select Atleast One item");
                flag = false;
            }
            else {
                document.getElementById("<%=hid.ClientID %>").value = jsVar_Orders_OrderId;
                var answer1 = confirm("Are You Sure You Want to Delete ?");
                if (answer1) {
                    flag = true;
                    document.aspnetForm.submit();
                }
                else {
                    flag = false;
                }
            }
            return flag;

        }

hid_Hospital_HospitalId.ClientID (Hiddenfield) declare hiddent field in ur aspx page

In code behid

on click on delete button

Id = (HiddenFieldvalue)

char[] separator = new char[] { '|' };
                string[] strProductId = ProductId.Split(separator);
                string[] strProductQuantity = ProductQuantity.Split(separator);
                for (int i = 0; i < strProductId.Length - 1; i++)
                {
                    int ProdId = Convert.ToInt32(strProductId[i]);

                    

                    Result = fn_Delete(ProdId);

                }
