CS:

protected void gv_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            CheckBox checkbox1 = e.Row.FindControl("checkbox1") as CheckBox;
            RequiredFieldValidator rfv = e.Row.FindControl("rfv") as RequiredFieldValidator;
            DropDownList drpPaymentMethod = (DropDownList)e.Row.FindControl("drpPaymentMethod");
            // you can just pass "this" instead of "myDiv.ClientID" and get the ID from the DOM element
            checkbox1.Attributes.Add("onclick", "UpdateValidator('" + checkbox1.ClientID + "','" + drpPaymentMethod.ClientID + "','" + rfv.ClientID + "');");
            if (!checkbox1.Checked)
                drpPaymentMethod.Attributes.Add("disabled", "disabled");
        }
    }

javascript:

function UpdateValidator(chkID, drpID, validatorid) {
        //enabling the validator only if the checkbox is checked
        var enableValidator = $("#" + chkID).is(":checked");

        if (enableValidator)
            $('#' + drpID).removeAttr('disabled');
        else
            $('#' + drpID).attr('disabled', 'disabled');

        var vv = $('#' + validatorid).val();

        ValidatorEnable(document.getElementById(validatorid), enableValidator);
    }
